處理飲用水的話,含量低的聚合氯化鋁會有較多雜質和水不溶物,所以要求用高含量。特別是造紙,化妝品制作中更是要用高含量的。 處理飲用水必須用飲水級的,工業(yè)級的在檢測時不檢測重金屬,另外水不溶物也高于飲用水的,總的來說飲用水級的關乎人命,不能亂用,一定要是真正的飲用水級的,如果工業(yè)級的被用于飲用水,隱患很多。而且純度不同,工業(yè)用都是26-28%,飲用水用30%。 而污水處理的話,含量高低要求并不嚴格,含量低的不是太多就行,可以多投放些藥劑也可以達到預定的效果。 ![]() 河南安家凈環(huán)保科技有限公司專業(yè)生產(chǎn)聚氯化鋁,主要分為飲水級,工業(yè)級,生產(chǎn)工藝主要分為噴霧法,滾筒法,資源貧乏山區(qū)的水處理時,直接加入水箱或水池中,攪拌均勻后靜止放置,上清液使用。一般情況下,50kg的水使用1g噴霧干燥型聚合氯化鋁。首先將噴霧干燥型聚合氯化鋁溶于10%~30%的水溶液中,然后加入待處理水中。根據(jù)處理后水的濁度,可適當提高或降低耗水量。 與普通聚合氯化鋁相比,噴霧干燥型聚合氯化鋁具有較好的吸附性能、較大的絮凝塊、沉降效果和處理后的水質較好。一般噴霧干燥型聚合氯化鋁采用更加先進的生產(chǎn)工藝,噴霧干燥法生產(chǎn)的聚合氯化鋁也分為了飲水級聚合氯化鋁和工業(yè)級聚合氯化鋁以及食品級聚合氯化鋁。飲水級聚合氯化鋁主要用于人們的日常飲用水,工業(yè)級聚合氯化鋁主要用于工業(yè)廢水的處理,而食品級聚合氯化鋁多用于食品添加劑和醫(yī)用方面。 噴霧干燥型聚合氯化鋁的產(chǎn)品質量很多時候關系到人們的生命健康,因此,生產(chǎn)艱難的凈水材料行業(yè)發(fā)展2020水環(huán)境保護的發(fā)展前景 2020年是一個不平凡的一年 剛結束報告中兌今年各個行業(yè)經(jīng)濟發(fā)展包括為了一到兩年的經(jīng)濟增長做出了預期判斷 保民生;A成了關鍵 保穩(wěn)定是當下務 凈水行業(yè)涉及的產(chǎn)業(yè)一樣是很大的 從工廠生產(chǎn)排位到老百姓的飲用水 河流質量 包括近兩年來各個地方推行的改水改廁村鎮(zhèn)污水綜合處理規(guī)劃 循環(huán)使用 聚丙烯酰胺聚合氯化鋁 聚合硫酸鐵這些水解材料成了非常需要的產(chǎn)品 洗沙廠在4月之后也進入了高發(fā)展階段 同樣離不開凈水材料的應用 總結一下實際生意洽談中遇到的問題 近期接到好多個洗沙場老板電話 很多都是剛上的污水洗沙設備 壓濾機等 投資都是幾百萬上千萬 幾個月的努力調試生產(chǎn) 到現(xiàn)在到了污泥脫水時 沙場老板很多都不能跟我們這些藥劑陰離子聚丙烯酰胺廠商達成合作信任 從寄樣品實驗選型到后期發(fā)10袋貨試用 一切問題都結局了 沙場老板還是要安排1-2噸藥劑使用后再付款 親愛的污水廠沙場老板 我們的產(chǎn)品質量已經(jīng)展現(xiàn)在您面前了 洗沙本來也不是很復雜的問題 質量保證是做一個商人基本的原則底線 陰離子聚丙烯酰胺的分類也無法低水解 喝高粘稠 洗沙廠用的基本價位在6000-8000之間 如果做循環(huán)水用 再加點pac 聚合氯化鋁就可以 24含量就夠用了 生意是談的 但也是有底線的 建立在互相信任的基礎上 我們免費上機實驗在免費提供1-2袋試用 這已經(jīng)使我們的真誠 誠意 歡迎各位老板寄樣選型 包括聚丙烯酰胺聚合氯化鋁 現(xiàn)在生化培菌處理也很流行 氨氮去除劑 醋酸鈉 葡萄糖也同樣有銷售 2020眼看就要過半 經(jīng)濟需要穩(wěn)定 保生產(chǎn)保穩(wěn)定 保民生 離不開我們凈水人的努力 為青山綠水努力 噴霧干燥型聚合氯化鋁具有明確而嚴格,可以保證人們的健康和安全。 滾筒式聚氯化鋁 鋁含量一般,水不溶物高,多用于污水處理. 板框式聚氯化鋁 鋁含量高, 水不溶物低. 用于污水處理和飲用處理.AM聚丙烯酰胺的合成及工藝物理特性:PAM由丙烯腈與水在骨架銅催化劑作用下直接反響生成聚丙烯酰胺再經(jīng)離子交流聚合單調,等工序即得廢品,工藝簡介如下:催化劑:催化水合CH2=CHCN+H2O 濕度 CH2=CHCONH2 聚合nCH2=CHCONH2-引發(fā)劑-CH2CHCONH2 聚丙烯酰胺工業(yè)用處:聚丙烯酸胺(PAM)分子量高、水溶性好、可調理分子量,并能夠引進各種離子基團以得到特定的性能。低分子量是分散資料有效增調劑或穩(wěn)定劑,高分子量是重要的絮凝劑,它能夠制造出親水而水不溶性的凝膠,它對許多團體外表和溶解物質有良可以作為凈水藥劑使用,也可以在造紙領域被當做助留劑使用,部分造紙使用草漿纖維較短,細胞雜質較高,導致了紙張強度較差,抄紙過程中濾水困難。對于此問題處理辦法有兩種:機械截留和膠體絮凝。 機械截留類似于過濾作用,它適用于紙張中較長部分纖維,纖細組分隱藏高的原因無法由此說明,助留劑的助留作用也無法用此解釋; 膠體絮凝作用為:凝聚作用和絮凝作用。分子量較小或者無機鹽、電荷密度較高的聚合物使膠體懸浮液穩(wěn)定性喪失從而發(fā)生絮聚作用稱之為凝聚作用,經(jīng)過電荷中和、異相凝聚和補綴作用幾種方法產(chǎn)生的沉積物。聚合氯化鋁是指聚凝作用中所提到的無機鹽。電荷密度較高的聚合物。 運用聚合氯化鋁處理了造紙進程由酸性改為中、堿性規(guī)模,紙漿中的陰離子雜質的問題,紙機操作以及紙質量的一系列問題,聚合氯化鋁帶有陽電荷,可以有效的控制陰離子的作用,有利于紙張濾水性 改善,聚合氯化鋁極容易在纖維外表形成吸附,還可以將帶有負電荷的填料和纖維吸附,使細料的藏著率有效的提高,漿料的濾水功效得到進一步的改善好的粘附力。由于以上性能PAM普遍應用于絮凝、增稠、減阻、擬膠、粘結、阻垢等范疇 。 陰離子聚丙烯酰胺依據(jù)不同用處和用戶對產(chǎn)品性能的央求,可選用不同分子量運用。 在工業(yè)廢水處置中,特別是關于懸浮顆粒、較粗、濃度高、粒子帶陽電荷,水的PH值為中性工堿性的污水如鋼鐵廠廢水,電鍍廠廢水,冶金廢水,洗煤廢水等污水處置效果很好。 在飲用水處置。我國很多自來水廠的水源自江河泥少及礦物質含量高,比擬混濁,雖經(jīng)過沉淀處置,但仍達不到央求,需求投加絮凝劑,才干使水質變清,很多自來水廠采用無機絮凝劑,但投加量大,構成污泥量增大效果不好,采用陰離子聚丙烯酰胺作絮凝劑,投加量是無機絮凝的50分之一但效果是無機絮凝劑的幾倍至幾十倍,特別是我公司消費的聚丙烯酰胺,剩余單體已抵達食品級(小于0.05%),接近國外先進程,對處置飲用水更為合適,關于有機物污染嚴重的江河水和陰離子聚丙烯酰胺配合運用效果更好。 聚丙烯酰胺用作淀粉廠及酒精廠的流失淀粉及酒糟的回收。往常很多淀粉廠排出的廢水內(nèi)淀粉很高,排放之后影響環(huán)境,糜費資源,投加PAM,使淀粉沉淀,沉淀物經(jīng)壓濾機壓濾變成餅類可作飼料,酒精廠大量的酒糟就是采用這種工藝加工的,黑龍江某酒精廠就是聚丙烯酰胺作絮凝劑,對酒糟中止回收的而且獲得了很大的經(jīng)濟效益。 ![]() ![]() 聚丙烯酰胺用作油田調剖堵水的堵水劑,三次采油的驅油劑。 聚丙烯酰胺用作造紙助劑,PAM在造紙方面用處很普遍,可作為長纖維造紙分散劑,干濕加強劑,助留,助濾劑及造紙廢水的絮凝劑等。 最新型的水處置劑聚丙烯酰胺,在很多場所處置污水和上水時,陰離子聚丙烯酰胺和陽離子聚丙烯酰胺配合運用要比單獨運用一種離子型聚丙烯酰胺產(chǎn)生十分顯著和協(xié)同效應,PAM對降低外表張力的才干要遠遠大于同條件下陽離子或陰離子單獨存在的才干,為抵達降低外表張力的央求,需求同時運用陰離子和陽離子聚丙烯酰胺,便兩者如運用不當,會產(chǎn)生白色沉淀物,失去運用效果 。而PAM具有兩性離子的特性,它能夠完成陰離子、陽離子的配合協(xié)同作用,面沒有任何沉淀物的產(chǎn)生,特別是對水質狀況比擬復雜或水的性質經(jīng)常變化的,運用PAM作為處置絮凝劑更為便當,效果更好。 在污水預處置中采用的污泥取自以錢塘江水為水源的沉淀池,該水廠以聚合氯化鋁PAC為絮凝劑。污泥經(jīng)自然濃縮到含固率為2.7%~2.8%,經(jīng)測定,污泥中有機物含量為12.1%,sj如含量為52.1%,Al。含量為20.2%。 PAM有陽離子型、陰離子型和非離子型三品種型。非離子型PAM溶解速度較慢,普通不用于污泥預處置,因而實驗僅選用兩種有代表性的陽離子聚丙烯酰胺和陰離子聚丙烯酰胺。陽離子型PAM分子量1200萬,丙烯酰胺單體含量0.012%。陰離子型PAM分子量1250萬,丙烯酰胺單體含量0.013%。兩種PAM配制濃度均為0.05%%,冰箱冷藏24h后運用。 (1)PAM預處置污泥取lOOml污泥,放入300ml的燒杯中,采用六聯(lián)攪拌機以1130rpm的轉速快 速攪拌30s后疾速投加~定量制備好的PAM,繼續(xù)以lOOrpm的轉速攪拌30s, 然后降低攪拌機轉速到20~30rpm慢速攪拌60s促進絮凝。分別測定預處置后污泥的比阻、毛細吸水時間(CST)、過濾液的粘度和離心液的粘度。 (2)比阻按考克力(Coackley)提出的實驗辦法,采用布氏漏斗實驗。布氏漏斗的直徑為80mm,濾紙采用由70mm定量中速濾紙,實驗真空度控制為0.01MPa。實驗反復3次取均勻值。 (3)為了降低比阻,進步污泥脫水效果,在污泥脫水前普通均需對污泥中止預處置。污泥預處置的辦法有冰凍一凍結預處置、熱處置、酸處置、堿處置、石灰預處置和高分子絮凝劑預處置等,其中高分子絮凝劑聚丙烯酰 ![]() ![]() ![]() 胺(PAM) 預處置是目前國內(nèi)外采用最普遍的預處置辦法。 (4) 聚丙烯酰胺絮凝劑預處置普通占整個污泥處置費用較高的比例,因而,聚丙烯酰胺的優(yōu)加率的合理肯定對降低污泥預處置費用相當關鍵。對選擇聚丙烯酰胺的實驗辦法的研討已展開多年,包括比阻、CST值、污泥流變性、分別液粘度、活動電流等。The synthesis and process physical properties of AM polyacrylamide: PAM is prepared by direct reaction of acrylonitrile with water under the action of framework copper catalyst, and then dried by ion exchange polymerization. The process is as follows: catalyst: catalytic hydration CH2 = CHCN + H2 humidity CH2 = CHCONH2 polymerization nCH2 = CHCONH2 - initiator - CH2CHCONH2 Industrial uses of polyacrylamide: Polyacrylamide (PAM) has high molecular weight, good water solubility, adjustable molecular weight, and can introduce various ionic groups to obtain specific properties. Low molecular weight is an effective additive or stabilizer for dispersing materials. High molecular weight is an important flocculant. It can produce hydrophilic and water-insoluble gel, which has good adhesion to many groups of surface and dissolved substances. Because of the above properties, PAM is widely used in flocculation, thickening, drag reduction, glue imitation, bonding, scale inhibition and other fields. Anionic polyacrylamide can be used in different molecular weights according to different uses and user's requirements for product performance. In industrial wastewater treatment, especially for suspended particles, coarser, high concentration, positive charged particles, neutral and alkaline wastewater such as iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other wastewater treatment effect is very good. In drinking water treatment. The water source of many Waterworks in our country is low in mud and high in mineral content, which is turbid. Although it has been treated by precipitation, it still can not meet the requirements. Flocculants are needed to make the water quality clear. Many waterworks use inorganic flocculants, but the amount of inorganic flocculants is large, resulting in poor effect of sludge increase. Anionic polyacrylamide acrylamide monomer was 0.012%. The molecular weight of anionic PAM was 12.5 million and the content of acrylamide monomer was 0.013%. The concentration of two kinds of PAM is 0.05%. They are used after refrigeration for 24 hours. (1) PAM pretreatment sludge takes lOml sludge and puts it into a 300 ml beaker. Six-unit mixers are used to mix at 1130 RPM speed for 30 seconds, and then the PAM is added to the sludge quickly and quantitatively. The PAM is stirred at lOOrpm speed for 30 seconds, then the speed of the mixer is reduced to 20-30 rpm and the slow stirring speed is 60 seconds to promote flocculation. The specific resistance of pretreated sludge, capillary water absorption time (CST), the viscosity of filtrate and the viscosity of centrifuge were measured. (2) The specific resistance is tested by Brinell funnel according to the test method proposed by Coackley. The diameter of Brinell funnel is 80 mm. The filter paper is made of 70 mm medium speed filter paper. The vacuum degree of the test is controlled to 0.01 MPa. The experiment was repeated three times to get the average value. (3) In order to reduce specific resistance and improve sludge dewatering effect, sludge should be pretreated before sludge dewatering. Sludge pretreatment methods include freeze-thaw pretreatment, heat treatment, acid treatment, alkali treatment, lime pretreatment and polymer flocculant pretreatment. Polymer flocculant polyacrylamide (PAM) pretreatment is the most widely used pretreatment method at home and abroad. (5)實驗研討標明:投加陽離子型和陰離子型PAM后污泥比阻都降低近2個數(shù)量級,顯著改善了污泥的脫水性能。陰離率為0.3kg/T干污泥,陽離子聚丙烯酰胺絮凝劑,可見陰離子型PAM的投加率遠小于陽離子型PAM的投加率,且陰離子型PAM的價錢約是陽離子型PAM價錢的1/2,故陰離子型PAM可作為自來水廠污泥預處置藥劑的首選。 (6)依據(jù)CST值變化肯定PAM最投加率與測定比阻得到的最投加率分歧。并且CST值與比阻之間存在線性相關關系,比阻值越大,CST值越大,因而能夠采用CST值來近似替代污泥比阻反映污泥的脫水性能。與比阻相比,cST值測定快速、煩瑣,不但適用于實驗室研討,還可用于消費現(xiàn)場,快速理解污泥脫水性能的變化,使操作人員及時調楚PAM投加率,儉省藥劑費。is used as flocculant, and the dosage is inorganic flocculant. One fiftieth of the flocculants, but the effect is several times to dozens of times that of inorganic flocculants. Especially the polyacrylamide produced by our company, the residual monomers have reached the food grade (less than 0.05%), close to the advanced level abroad, non-toxic, more suitable for the treatment of drinking water, and better for the use of organic pollutants polluted river water and anionic polyacrylamide. Polyacrylamide is used to recover lost starch and distiller's grains in starch and alcohol factories. At present, the starch in the waste water discharged by many starch factories is very high. After discharging, it affects the environment, wastes resources, and adds PAM to make starch precipitate. The precipitate is filtered by pressure filter to become cake and can be used as feed. A large number of distillers'grains in the alcohol factories are processed by this process. A certain alcohol factory in Heilongjiang Province uses polyacrylamide as flocculant, which recycles the distillers' grains and obtains a great deal of experience. Economic benefits. Polyacrylamide is used as water shutoff agent for profile control and water shutoff in Oilfield and oil displacement agent for tertiary oil recovery. Polyacrylamide is used as paper-making additive. PAM is widely used in paper-making. It can be used as long fiber paper-making dispersant, wet and dry reinforcing agent, retention aid, filter aid and flocculant of paper-making wastewater. The latest type of water treatment agent polyacrylamide, when treating sewage and water in many occasions, the combination of anionic polyacrylamide and cationic polyacrylamide has a very significant and synergistic effect than using one kind of ionic polyacrylamide alone. The ability of PAM to reduce surface tension is much greater than the ability of cations or anions existing alone under the same conditions. For the requirement of low surface tension, both anionic and cationic polyacrylamide need to be used at the same time. If they are used improperly, white precipitates will be produced and the effect of using them will be lost. PAM has the characteristics of amphoteric ions. It can complete the coordination of anions and cations. There is no precipitate on the surface. Especially, it is more convenient to use PAM as a flocculant because of the complex water quality or the changeable nature of water. The sludge used in sewage pretreatment is taken from the sedimentation tank with Qiantang River water as its source of water, and PAC is used as a flocculant in the water plant. The sludge was naturally concentrated to a solid content of 2.7%-2.8%. The organic matter content in the sludge was 12.1%, SJ content was 52.1%, Al content was determined. The content was 20.2%. There are three types of PAM: cationic, anionic and nonionic. Non-ionic PAM dissolves slowly and is generally not used for sludge pretreatment. Therefore, only two representative cationic polyacrylamides and anionic polyacrylamides are selected in the experiment. The molecular weight of cationic PAM was 12 million and the content of (7)不管是陽離子聚丙烯酰胺絮凝劑還是陰離子聚丙烯酰胺絮凝劑,隨著投加率的增加,濾液和離心液粘度都呈現(xiàn)與比阻和CST值類似的變化規(guī)律,呈現(xiàn)了明顯的最小值,而且該最小值對應投加率與污泥比阻和CST值實一步的實驗研討。 噴霧干燥聚氯化鋁 鋁含量高, 水不溶物低,溶解速度快,用于飲用水及更高標準水處理. PAC聚氯化鋁由于噴霧干燥穩(wěn)定性好,適應水域寬,水解速度快,吸附能力強,形成礬花大,質密沉淀快,出水濁度低,脫水性能好等優(yōu)點,在同樣水質的情況下,噴霧干燥聚氯化鋁投加量減少,尤其在水質不好的情況下,噴霧干燥產(chǎn)品投量與滾筒干燥聚氯化鋁相比,可減少一半,不僅減輕了工人的勞動強度,而更重要的是減少用戶的制水成本。除此之外,用噴霧干燥產(chǎn)品可保證安全性,減少水事故,對居民飲用水非常安全可靠。When treating drinking water, polyaluminium chloride with low content will have more impurities and water insolubles, so high content is required. Especially in papermaking, cosmetics production is to use high content. Drinking water must be treated at drinking water level. Heavy metals are not detected at industrial level, and insoluble substances in water are also higher than drinking water. Generally speaking, drinking water level is related to human life and can not be used arbitrarily. It must be a real drinking water level. If industrial level is used for drinking water, there are many hidden dangers. And the purity is different, industrial use is 26-28%, drinking water is 30%. And sewage treatment, the content requirements are not strict, low content is not too much, you can put more medicines can also achieve the desired effect. Henan an Jia Jing Environmental Protection Technology Co., Ltd. specializes in the production of polyaluminium chloride, which is mainly divided into drinking water level and industrial grade. The production process is mainly divided into spray method and roller method. Drum-type polyaluminium chloride is generally used for sewage treatment because of its high water insoluble content. Plate-frame polyaluminium chloride has high content and low water insoluble. It is used for sewage treatment and drinking treatment. Spray drying has high content of polyaluminum chloride, low insoluble substance and fast dissolution rate. It is used for drinking water and higher standard water treatment. PAC polyaluminium chloride has the advantages of good stability in spray drying, wide adaptation to water area, fast hydrolysis speed and strong adsorption capacity. It has the advantages of large alum, high quality and fast sedimentation, low turbidity and good dewatering performance. Under the same water quality, the dosage of spray drying polyaluminum chloride is reduced, especially when the water quality is not good, the product volume of spray drying is compared with that of drum drying polyaluminum chloride. It can be reduced by half, which not only reduces the labor intensity of workers, but also, more importantly, reduces the cost of water production for users. In addition, spray drying products can ensure safety and reduce water accidents, which is very safe and reliable for drinking water. |
