Flocculating agent for industrial wastewater treatment and manufacturing method thereof

Abstract

The invention discloses a flocculating agent for industrial wastewater treatment and a manufacturing method thereof, and belongs to the field of water treatment agents. The flocculating agent is manufactured from, by weight, 8-18 parts of polyacrylamide, 5-15 parts of ferrous sulfate, 3-9 parts of aluminum potassium sulphate, 4-12 parts of polysilicate, 4-12 parts of aluminium polychlorid, 8-12 parts of polyoxyethylene, 5-10 parts of barium carbonate, 10-25 parts of tripoli, 8-18 parts of zinc chloride, 3-9 parts of aluminium chloride, 5-15 parts of polymeric phosphate-ferric chloride, 1-5 parts of polymeric ferric phosphate and 50-70 parts of water. The flocculating agent for industrial wastewater treatment is short in flocculent precipitate time, good in effect and low in cost, the active emulsifying ability of hydrones is improved, hazardous substances and heavy metal of water are degraded, high-concentration and high-turbidity wastewater and non-degradable wastewater can be effectively treated particularly, the flocculating agent can be widely used for municipal wastewater and various industrial wastewater treatment and polluted river and lake water treatment, and the treated water can be recycled.

Description

technical field [0001] The invention relates to a flocculant for treating industrial waste water and a preparation method thereof, belonging to the field of water treatment agents. Background technique [0002] Coagulation treatment is one of the key links in wastewater treatment, which can remove turbidity and pollution, and reduce the pollution load of subsequent sewage treatment. The flocculant is the key factor to determine the effect of coagulation treatment, and has an important impact on the operation status of the subsequent process, the final effluent water quality and cost. According to its chemical composition, flocculants can be generally divided into two types: inorganic flocculants and organic flocculants. Inorganic flocculants include inorganic coagulants and inorganic polymer flocculants; organic flocculants include synthetic organic polymer flocculants, natural organic polymer flocculants and microbial flocculants. Flocculants are mainly groups with positi...

Problems solved by technology

Due to the current disadvantages of slow flocculation and sedimentation and high drug consumption

Polymer flocculants such as basic polyaluminum chloride (PAC), polyaluminum sulfate, polyferric sulfate, etc., overcome the disadvantages of low processing efficiency of low molecular flocculants, but their cost is high, and when low temperature and low turbidity Poor processing effect

Organic flocculants are generally polymers, such as polyamine flocculants, quaternary ammonium starch-based flocculants, and polyacrylamide flocculants. Among them, polyacrylamide has the advantages of less dosage, strong ability to clarify water quality, and fast flocculation speed. It is not easily affected by the pH value of water, and the amount of sludge generated is less, which has been widely used. However, polyacrylamide has strong neurotoxicity and certain carcinogenicity. When a large amount of polyacrylamide is used to treat wastewater, it will produce polymer residues. , destroying the biological chain of the water body, thereby affecting human health
