絮凝作用逐漸增強(qiáng)的作用;一起,聚丙烯酰胺分子的負(fù)電性亦逐漸增強(qiáng),又阻礙了其與負(fù)電性的泥沙雜質(zhì)相吸附,并且在吸附架橋中起 首要作用的活性基團(tuán)-酰胺基也不斷減少,然后跟著水解度的添加能夠分為膠體、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(lái)是我們的經(jīng)歷所得,希望您會(huì)感興趣。
??在平常假如我們常常運(yùn)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(dāng)?shù)厥羌拇娑暌陨系?,但假如配成溶液的?huà),它的寄存時(shí)刻就有限了,一般說(shuō),溶液濃度為0.1%的時(shí)候,非離子與陰離子聚丙烯酰胺溶液不會(huì)超過(guò)一周的時(shí)刻,陽(yáng)離子聚丙烯酰胺溶液則不會(huì)超過(guò)一天,而且溶液的穩(wěn)定性與溶液的濃度有關(guān),配的濃度越濃,例如3%——5%的溶液寄存時(shí)刻越長(zhǎng),但3%——5%的溶液不能直接去處理污水,這種在運(yùn)用前需要稀釋?zhuān)?yáng)離子聚丙烯酰胺溶液PH值小于5.5的時(shí)后比較穩(wěn)定,假如大于6.0的話(huà),就會(huì)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(gè)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(dāng)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(duì)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(xué)降解的催化劑,所以在制造、搬運(yùn)與儲(chǔ)存聚丙烯酰胺溶液的話(huà),一定要盡量避免鐵離子進(jìn)入與溶液觸摸設(shè)備要用塑料、不銹鋼、玻璃鋼或表面涂料樹(shù)脂的碳鋼制造。
,又存在使絮凝作用逐漸變差的要素。 陰離子聚丙烯酰胺作為綜合成果:水解比過(guò)大,加堿費(fèi)用較高,水解比過(guò)小,又會(huì)使反應(yīng)不足,陰離子型聚丙烯酰胺的混凝或助凝作用較差。 所以陰離子聚丙烯酰胺不一定水解度越高越好,什么都會(huì)有個(gè)限度,適宜的才是zui優(yōu)的河南安家凈環(huán)保是一家專(zhuān)業(yè)出產(chǎn)各種水處理藥劑,致力于綠色環(huán)保可再生資源的繼續(xù)使用,很多投入了科 研資金,首要產(chǎn)品有聚丙烯酰胺絮凝系列,聚合氯化鋁系列,聚合硫酸鐵系列,堿式氯化鋁等均受到全國(guó)客戶(hù)的一致好評(píng),咱們將一如即往的出產(chǎn)出品質(zhì)優(yōu)質(zhì)的產(chǎn)品來(lái)報(bào)答客戶(hù)對(duì)咱們一向的支持聚丙烯酰胺生產(chǎn)及市場(chǎng)現(xiàn)狀分析,可得以下幾點(diǎn)認(rèn)識(shí):

It can reach the intent of deep dephosphorization at the same time of coagulation and turbidity removal of urban water source.
Thus, the phosphorus content in treated drinking water can be reduced to below the threshold value, without changing the original water treatment process, without adding large water treatment structures, which is simple, economical and practical, and can achieve remarkable social and economic benefits.
The amount of phosphorus removal agent used in river regulation will not cause adverse effects. After all, iron is also a trace element needed for microbial growth. However, if the dosage is too large, the sludge activity will be affe
聚合氯化鋁的使用方案后在進(jìn)行大量的投加使用,其中小試需要得到的有聚合氯化鋁的類(lèi)型、含量、溶解濃度、使用方法等。那么如何進(jìn)行聚合氯化鋁的小試呢?河南環(huán)保科技有限公司為您介紹一下。
聚合氯化鋁的小試一般是先將聚合氯化鋁配置成5%濃度的水溶液來(lái)進(jìn)行實(shí)驗(yàn)。通常為了方面可以稱(chēng)取5g的聚合氯化鋁固體,然后添加到100ml的水中,就可以配置成聚合氯化鋁的水溶液。然后將需要處理的污水進(jìn)行取樣并分配成相同的若干份,然后就可以使用聚合氯化鋁進(jìn)行小試。
用滴管將聚合氯化鋁的水溶液慢慢添加到污水中,
