Phosphorus removers for domestic and municipal sewage are developed for low-concentration phosphorus removal, targeting incomplete and unstable postnatal phosphorus treatment. The principle of domestic and municipal sewage phosphorus removal agents is to form an adsorption system in water. Through the adsorption, bridging, and precipitation of sewage phosphorus, as well as the adsorption of micelles, it precipitates together with activated sludge during precipitation to achieve complete phosphorus removal.the goal of.
The water quality characteristics of municipal domestic sewage are mainly as follows: the wastewater contains a large amount of grease, food residues, etc., with high suspended solids and large color; the wastewater contains a large amount of residual food, etc., resulting in a strong taste of the wastewater and easy to stink; the quality and quantity of the wastewater The fluctuations are relatively large; the concentration of organic matter in the wastewater is large, and the sources of nitrogen and phosphorus are also high. Direct discharge can easily cause eutrophication of the water body.
biofloc
Biological flocculation is a decontamination method that uses microorganisms or metabolites produced by microorganisms to evolve flocculation and sedimentation. Microbial flocculants are a type of metabolites produced by microorganisms and secreted out of cells with flocculating activity. It is generally composed of polysaccharides, proteins, DNA, cellulose, glycoproteins, polyamino acids and other high molecular substances. The molecules contain a variety of functional groups, which can cause colloid suspensions in water to aggregate and precipitate with each other.
Biosorption method
Biosorption method is a method that uses the chemical structure and composition characteristics of the organism itself to adsorb metal ions dissolved in water, and then removes the metal ions in the aqueous solution through solid-liquid two-phase separation.
