can be applied to various wastewater treatment (for sewage treatment using polyacrylamide is generally divided into two processes, one is the high polymer electrolyte and particle surface charge neutralization; 2 it is the long chain of polymer electrolyte and particle floccules bridge formation. The main purpose of flocculation is that by joining polyacrylamide the tiny suspended particles and colloid particles in the sludge together form a bulky floccules. With the increase of floccules, sedimentation velocity increasing. In order to better pressure mud through filter press, which reached the requirements of environmental protection processing, dry mud sinotrans for incineration.)
is a polymer water-soluble organic polymer with a molecular weight of several million to tens of millions, forming a larger flocculation between particles and the resulting massive surface adsorption.
At present domestic representative of polyacrylamide polymer PAM: nonionic polyacrylamide (abbreviated NPAM, molecular weight of 800-15 million), the anionic polyacrylamide (abbreviated APAM, molecular weight of 800-20 million), cationic polyacrylamide (abbreviated CPAM, molecular weight of 800-12 million, ion of 10% - 80%).
The dosage is usually one millionth of a millionth of the amount of wastewater.
Therefore, it is mainly formed by artificial synthesis.
