加速顆粒沉降。 Flocculants are mainly used in the field of water supply and sewage treatment. It is a polymer coagulant added to wastewater. After the polymer coagulant dissolves, the polymer is bed.方法所得出的分類是不一樣的,假如依照離子型可分為陰、非、兩性及陽離子聚丙烯酰胺,假如依照形狀的話,能夠分為膠體、渙散液、乳液和干粉顆粒四種形狀,那么這四種形狀哪一種更適合我們
呢?公司給您一些主張,接下來是我們的經(jīng)歷所得,希望您會感興趣。
??在平常假如我們常常運用,能夠選擇干粉顆粒狀聚丙烯酰胺,The classification obtained by the b is different. If the ionic type can be divided into Yin, non, amphoteric and cationic polyacrylamide, if according to the shape, it can be divided into four shapes: colloid, laxity, emulsion and dry powder. Which of these four bs is more suitable for us? The company gives you some suggestions. Next is our experience. I hope you will be interested.
In general, if we often use it, we can choose dry powder granular polyacrylamide. Because of its highest solid content, dry powder polyacrylamide is generally stored in dry and cool places for more than two years, but if mixed with solution, its storage time will be limited. Generally speaking, when the concentration of solution is 0.1%, non-ionic and anionic polyacrylamide will dissolve. The stability of cationic polyacrylamide solution depends on the concentration of the solution. For example, the more concentrated the solution is, the longer the storage time of 3%-5% solution is, but the 3%-5% solution can not be directly used to treat sewage. This solution needs to be diluted before use, and the PH value of cationic polyacrylamide solution is less than 5.5. Stability, if greater than 6.0, will be due to hydrolysis and failure, water medium dispersion polyacrylamide shelf life of six months.
Therefore, polyacrylamide is still a better choice of solids, can be used with the mix, do not cause waste.
Of course, we must pay attention to the conditions and taboos of preserving polyacrylamide. Polyacrylamide is more sensitive to iron ions, calcium ions and magnesium ions than anionic polymers. In particular, iron ions are catalysts for the chemical degradation of all polyacrylamide. Therefore, in the manufacture, handling and storage of polyacrylamide solutions, we must try to avoid iron ions entering and touching the solution. The equipment should be made of plastics, stainless steel, FRP or carbon steel with surface coating resin.由于它的固含量,一般情況下干粉聚丙烯酰胺在干燥、陰涼的當?shù)厥羌拇娑暌陨系?,但假如配成溶液的話,它的寄存時刻就有限了,一般說,溶液濃度為0.1%的時候,非離子與陰離子聚丙烯酰胺溶液不會超過一周的時刻,陽離子聚丙烯酰胺溶液則不會超過一天,而且溶液的穩(wěn)定性與溶液的濃度有關,配的濃度越濃,例如3%——5%的溶液寄存時刻越長,但3%——5%的溶液不能直接去處理污水,這種在運用前需要稀釋,陽離子聚丙烯酰胺溶液PH值小于5.5的時后比較穩(wěn)定,假如大于6.0的話,就會由于水解的原因而失效,水介質(zhì)渙散型聚丙烯酰胺保質(zhì)期為六個月。
??所以聚丙烯酰胺仍是選用固體的比較好,能夠做到隨配隨用,不造成糟蹋。
??當然大家一定要注意保存聚丙烯酰胺各種條件和忌諱,聚丙烯酰胺對鐵離子、鈣離子、鎂離子比陰離子聚合物質(zhì)靈敏,尤其是鐵離子是造成所有聚丙烯酰胺化學降解的催化劑,所以在制造、搬運與儲存聚丙烯酰胺溶液的話,一定要盡量避免鐵離子進入與溶液觸摸設備要用塑料、不銹鋼、玻璃鋼或表面涂料樹脂的碳鋼制造。

水污染的破壞很明顯,聚氯化鋁對處理水污染是合理的。生產(chǎn)聚合氯化鋁這些問題一定要重視!
聚氯化鋁生產(chǎn)過程中有哪些相關問題?
??1.不溶物聚合氯化鋁的堿度對聚合氯化鋁的絮凝效果有很大影響。作為聚合氯化鋁的專業(yè)生產(chǎn)廠家,通過對一些具體實例的對比研究和對聚合氯化鋁絮凝效果的實驗,發(fā)現(xiàn)聚合氯化鋁的絮凝效果與堿度非常相似。
通過焦化廢水混凝處理試驗,得出了焦化廢水處理所需聚合氯化鋁的佳堿度、投加量和pH值范圍,并根據(jù)不同堿度下處理的聚合氯化鋁水鋁含量的不同,得出了利用率。
廢水經(jīng)處理后,鋁含量與聚合氯化鋁的堿度密切相關,在相同堿度下,pH值對殘余鋁含量有很大影響。根據(jù)聚合氯化鋁的實驗數(shù)據(jù),當pH值接近中性時,水中的殘余鋁含量最小,pH值會使殘余鋁含量增加。當聚合氯化鋁的堿度為1.5時,處理后的廢水中鋁的含量很低。
堿度也是聚合氯化鋁生產(chǎn)中必須控制的重要指標。由于它對聚合氯化鋁的絮凝效果影響很大,是需要嚴格執(zhí)行的標準之一。
此外,聚合氯化鋁的絮凝效果不僅與堿度密切相關,而且受聚合氯化鋁含量和不溶物的影響也很大。在聚合氯化鋁的使用過程中,合理的使用方法也是保證聚合氯化鋁絮凝效果的前提之一
??標準規(guī)定了市售聚氯化鋁的不溶物含量。由于國內(nèi)企業(yè)一般以礦物為原料,礦物等原料一般成分復雜,需要粉碎并加入粉末中。粉末越細,氧化鋁的溶解速率越高。但是,諸如不溶物質(zhì)的雜質(zhì)更難以沉淀。
??2.產(chǎn)品純度問題
??氧化鋁含量是聚氯化鋁產(chǎn)品的重要指標。通常認為含量越高,純度越高,質(zhì)量越好。在中國的聚氯化鋁行業(yè),除少數(shù)公司外,可以生產(chǎn)一些系列產(chǎn)品和特殊產(chǎn)品。大多數(shù)公司使用鋁土礦,鋁酸鈣和副產(chǎn)品生產(chǎn)單一的低質(zhì)量聚氯化鋁產(chǎn)品,生產(chǎn)規(guī)模小。技術(shù)含量低,產(chǎn)品有效成分氧化鋁含量低,雜質(zhì)多,高效低成本的復合聚鋁鹽和高純度聚氯化鋁產(chǎn)品少,不能滿足市場需求,特別是造紙工業(yè)的高純度。需要聚氯化鋁產(chǎn)品。
??3.劑量問題
??制備聚氯化鋁的方法很多,但它是一種酸溶液法和堿溶液法,用于實現(xiàn)一定規(guī)模的工業(yè)生產(chǎn),其中引起生產(chǎn)成本和氧化鋁溶解速率等問題。酸溶解方法比堿溶性方法更實用,酸溶液涉及濃度和劑量等問題。濃度越高,氧化鋁的溶解速率越大,但揮發(fā)性越強,因此應適當配置濃度。質(zhì)量分數(shù)通常約為20%;劑量小,氧化鋁溶解率低。當投資額很大時。制備的聚氯化鋁鹽堿度低,腐蝕性強。運輸很困難,因此有必要制定合理的劑量。

Thereafter, the construction of the concept factory was vigorously promoted. By the end of 2014, the preliminary design and site selection work will be completed, the overall design will be completed in 2016, and the project construction approval and construction design will be completed in 2017. Officials said that the first sewage treatment conceptual plant could be completed in 2019.
Wang Hongchen, deputy dean of the Environmental College of Renmin University of China, told reporters that a year and a half ago, the sewage treatment conceptual plant had gathered a group of powerful basic teams to carry out relevant experiments on the spot, build production and R&D centers, speed up the transbation of science and technology, and carry out extensive industrial cooperation. "One is to build the experience center of new technology, promote the research and development, transbation and promotion of new technology; the other is to build the production-oriented research and development center of municipal sewage treatment, and build a new model of new technology from laboratory to practical application. Thirdly, we should promote the development of wastewater treatment technology from laboratory to engineering, and create a new high ground for China's cooperative industries.
According to the introduction, the concept factory initially established the technical route of sustainable water treatment facing the future, and established the business model and innovation model of "ecological complex" and "production-oriented R&D center" guiding industrial development.
For the basic ideas of the technical route, experts said that the main way is to improve energy recovery by carbon segregation, and to achieve the level of water treatment available. The effluent standard of "concept plant" will be much higher than that of current sewage treatment plants, which is of great significance for improving the quality of water environment and promoting ecological construction. "In the future, the conceptual plant will be expanded to an ecological area, like a demonstration of an urban ecological complex, and ultimaby realize that a treatment plant can drive a city's ecosystem." Wang Hongchen said.
"Sewage treatment conceptual plant is an innovative work. It can not simply be regarded as a project, a project, a factory, but a social work to promote the leapfrog development of the industry." Wang Hongchen said so.
The damage of water pollution bly shows that polyaluminium chloride is a reasonable way to deal with water pollution.
As a new year's first film, the piglet's past New Year is not the same as most movie promotion or promotion films. It's a story of "who is page". It's a story of "who is Paige": Li Yubao, who stays behind, doesn't know what his grandson wants to be "Paige". Finally, a pink Page was welded with a blower and sent to his grandson.

Henan Settlement Net Hebei Science and Technology Co., Ltd. year, has gone through 14 years in the beginning, the experience of the storm and pain in the hearts of the people, sweat and tears, success and happiness intertwined. Settlement net do not want to do anything is to do a good job of products, after hard struggle, our plant water treatment pharmaceutical products to reach the national GB15892-2003 specification. And through the ISO 9001:2000 international quality system certification, from all aspects of checks, the perbance rate of the contract is 100%, the qualified rate of the products has reached 100%, which has been promulgated by the Municipal Technical Supervision Bureau as a reliable unit of quality and measurement.
According to the dosage of polyaluminium chloride in different water quality, the net settled polyaluminium chloride is introduced.
1. In low turbidity water, the solid polyaluminium chloride product is diluted by adding tap water in proportion of 1:3, and stirred until compleby dissolved.
2. In daily and production wastewater, the polyaluminium chloride product should be added about 30g per ton of wastewater. Then add diluted polyacrylamide products. (If the effect is not obvious, please reduce or increase the product dosage as appropriate. )
3. In the sewage treatment of paper mills, the b share of low turbidity water should be selected and equipped. If the effect is not obvious, it can be increased at a reasonable level.
4. When the turbidity of raw water is 100-500 mg/L, the dosage is 5-10 mg, i.e. 5-10 kg per thousand tons of water. It is better to carry out small-scale tests according to the characteristics of water quality before using, select the appropriate value, and then put it into use.

大多時候聚合氯化鋁的固體在我們進行直接觀察時,會因為聚合氯化鋁中有一些顆粒物質(zhì)或者塊狀物,尤其在滾筒型的聚合氯化鋁中存在更多,就異味聚合氯化鋁的產(chǎn)品質(zhì)量不行,其實這是不對的。聚合氯化鋁的水不溶物一般是由于生產(chǎn)原料和生產(chǎn)工藝決定的construction, and do not pollute building water.
污水處理廠常用的外部碳源是甲醇,工業(yè)葡萄糖等。甲醇應該是最理想的反硝化補充碳源,但其高成本,高毒性和運輸困難逐漸被其他產(chǎn)品所取代。工業(yè)葡萄糖通常用作額外的碳源。過程測試水質(zhì)測試中心在工業(yè)葡萄糖成分的測量和計算方面做得很好。在實驗室中,以1/100的比例添加工業(yè)葡萄糖,測量COD和BOD含量,并計算每10,000平方米污水的工業(yè)葡萄糖的理論劑量。劑量的劑量是根據(jù)在《給水排水設
