1, the above mentioned as a regulator of phosphorus removal flocculant, used to regulate sewage water quality, improve the phosphorus removal effect of phosphorus removal flocculant, reduce the amount of agents.
2. As a chemical phosphorus removal flocculant, a large number of calcium ions will be formed after the dissolution of complex alkali itself, and calcium ions will react with carbonate to generate calcium phosphate precipitates with microsolubility.
3. Remove SS in water, and use its own active white mud, diatomite and other adsorptive substances and the adsorptive substances and charged ions generated after hydrolysis to carry out electric neutralization and adsorption precipitation treatment with suspended substances in water, so as to greatly reduce the content of pollutants in water and improve the treatment effect.
4, as a metal ion removal agent, so as to improve the biodegradability of sewage, reduce the damage of metal substances in water to the biochemical system, improve the effect of biochemical phosphorus removal.
5, improve the alkalinity of water quality, supplement the alkali consumed by microbial phosphorus removal, improve the effect of biochemical treatment.
