Composite sewage treatment agent

Abstract

The invention discloses a composite sewage treatment agent. The composite sewage treatment agent is prepared from raw materials in parts by weight as follows: 10-20 parts of exocarpium, 5-10 parts of attapulgite, 8-15 parts of dodecyl dimethyl benzyl ammonium chloride, 5-15 parts of activated carbon, 5-10 parts of polyferric sulfate, 0.5-1 part of n-butyl acetate, 5-10 parts of sodium carbonate, 5-10 parts of sodium xylene sulfonate, 3-10 parts of sodium tripolyphosphate, 2-8 parts of tall oil fatty acid, 5-18 parts of a peracetic acid disinfection solution, 2-5 parts of lauryl betaine, 2-5 parts of octadecyl trimethyl ammonium chloride and 10-15 parts of fly ash. The sewage treatment agent can effectively reduce content of heavy metal ions, COD (chemical oxygen demand) and SS (suspended solids) of sewage; the preparation method is simple, and the product cost is lower; the sewage treatment period is short, and treated sewage can meet the cyclic utilization standard; the sewage treatment agent is free of toxic substances and is good in decoloration effect, and treated water is odorless.

Description

Technical field [0001] The invention relates to a sewage treatment agent, in particular to a composite sewage treatment agent. Background technique [0002] Sewage treatment agent, as the name implies, is an additive that needs to be used in sewage treatment, such as polyacrylamide, cationic polyacrylamide, anionic polyacrylamide, non-ionic, zwitterionic polyacrylamide, polyaluminum chloride, etc. in different uses Both can be used as sewage treatment agent. [0003] Polyscrylamide (Polyscrylamide) referred to as PAM, the molecular formula is: [CH 2 -CH(CONH 2 )] n , Is a linear polymer with a molecular weight of 4-20 million. The appearance of solid product is white or slightly yellow powder. The liquid is a colorless viscous colloid. It is easily soluble in water and decomposes when the temperature exceeds 120℃. . There are reports in the literature that foreign researchers have found that the degradation products of polyacrylamide can be used as nutrients for bacterial life ac...

Problems solved by technology

[0005] 1) The preparation method is complicated, resulting in higher product cost;

[0006] 2) The sewage treatment cycle is long, and the water quality after treatment is poor, which cannot meet the recycling standard;

[0007] 3) The sewage treatment agent contains toxic substances, which will cause harm to the body of workers and cause certain harm to the environment;

[0008] 4) The decolorization effect of sewage treatment is poor, and the treated water still has an odor
