The colloid in the sewage or sludge is rapidly precipitated through the precipitate or the hydrolysate thereof, so that large-particle precipitate which is convenient to separate is formed;
polyacrylamide is called PAM for short, is commonly called flocculant or coagulant, and belongs to a coagulant. The average molecular weight of PAM is from thousands to tens of millions, and there are several functional groups along the bond-shaped molecule, which can be mostly ionized in water, and adsorb the suspended particles in sewage, so that the macromolecular chains are intertwined and cross-linked to form a bridge, thereby enlarging the flocculation structure and thickening, and finally forming a precipitate.
After PAC/PAM is added into raw water, the PAC/PAM is fully mixed with water, most of colloidal impurities in the water lose stability, destabilized colloidal particles collide and agglomerate with each other in a flocculation tank to finally form flocs which can be removed by a precipitation method, and most of COD, organic matters, suspended matters and the like in water are finally removed in a precipitation sludge discharge mode.
