??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 method 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 forms 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 i

（工業(yè)葡萄糖在污水中的作用；污水處理中為什么要加工業(yè)葡萄糖）
二、污水處理調(diào)試期間投加工業(yè)葡萄糖等是為了提供碳源，這是為了更好的培育細(xì)菌，提高污水的可生化性，有效改進(jìn)污泥的親和性，比尿素的效果要來的快。若運(yùn)行的體系中COD、BOD不足以供給菌種生長繁衍的話，就需要另外投加，以防污泥老化，生物活性降低。
工業(yè)葡萄糖主要用于以活性污泥法處理污水。
參加活性污泥處理的微生物，在其生命活動(dòng)過程中，需要不斷從周圍環(huán)境的污水中汲取其所有必要的營養(yǎng)物質(zhì)，包括：碳源、氮源、無機(jī)鹽類以及某些生長素等。待處理的污水中有必要充分含有這些物質(zhì)。
碳是構(gòu)成微生物細(xì)胞的重要物質(zhì)，參加活性污泥處理的微生物對(duì)碳源需求量較大，一般以BOD5計(jì)，不該低于100mg/L。日子污水碳源比較充足，關(guān)于一些碳源不足的工業(yè)廢水則應(yīng)彌補(bǔ)碳源，如日子污水或是淀粉、葡萄糖等。
我廠是出產(chǎn)工業(yè)葡萄糖的專業(yè)廠家，出產(chǎn)的工業(yè)葡萄糖分為一級(jí)工業(yè)葡萄糖、二級(jí)工業(yè)葡萄糖、優(yōu)等工業(yè)葡萄糖和污水級(jí)專用葡萄糖。
咱們也可按用戶要求調(diào)配適用于客戶的產(chǎn)品。
