The main effects of Polyacrylamide (PAM) in water treatment are that (1) the dosage of flocculant is reduced, and the polyacrylamide is used as coagulant aid to be matched with other flocculants on the premise of reaching the same water quality, so that the dosage of flocculant can be greatly reduced; (2) The water quality is improved, and the polyacrylamide and the inorganic flocculant are matched for use in the drinking water treatment and the industrial sewage treatment, so that the water quality can be obviously improved; (3) The strength and sedimentation velocity of the floccules are improved, and the floccules formed by the polyacrylamide are high in strength and good in sedimentation performance, so that the solid-liquid separation velocity is improved, and sludge dewatering is facilitated; (4) The use of polyacrylamide can greatly reduce the dosage of inorganic flocculant, thereby avoiding the deposition of inorganic substances on the surface of equipment and slowing down the corrosion and scaling of the equipment.
In the application, the coagulant for sewage treatment is different from the flocculant in function, the coagulant can coagulate water-soluble pollutants into tiny insoluble matters, the flocculant is only responsible for coagulating tiny particles into large alum, that is, the coagulant is added in front, the flocculant is added after the coagulant, and the two medicaments are mutually matched to treat sewage.
In the application, in the drug-adding flocculation device, by utilizing the characteristic that water has different solubilities under different pressures, all or part of water to be treated (or treated) is pressurized and dissolved, the air dissolving amount in the water is increased, the air is introduced into the culture sewage added with the coagulant, and released under normal pressure, the air is separated out to form small bubbles, and the small bubbles are adhered to impurity floccules, so that the overall density of the floccules is lower than that of the water and rise, and solid-liquid separation is realized.
In the application, in the adsorption and filtration tank 301, the adsorption is to adsorb the organic matters in the sewage onto the surface of the activated carbon through the surface adsorption action of the activated carbon, so that the organic matters are extracted from the water, the water quality is effectively purified, and when the organic matters in the sewage are combined with the surface of the activated carbon, the electric charge on the surface of the activated carbon is changed, so that the organic matters on the surface of the activated carbon are adsorbed;
The filtering is carried out by taking laminar anthracite, sand, finely divided garnet or other materials as a bed layer, the top layer of the filtering bed is composed of the lightest and coarsest grade materials, and the heaviest and finest grade materials are placed at the bottom of the filtering bed, the principle is that the filtering is carried out according to depth, larger particles in water are removed at the top layer, and smaller particles are removed at the deeper part of a filter medium, so that the water quality reaches the standard after coarse filtering.
In the application, the sterilizing device adopts sodium hypochlorite for sterilization, and the most main action mode is that hypochlorous acid is formed through the hydrolysis of the sodium hypochlorite, and then the hypochlorous acid is further decomposed to form nascent oxygen [ O ], so that the protein of thalli and viruses is denatured by the extremely strong oxidizing property of the nascent oxygen, thereby killing pathogenic microorganisms.
