Heavy metal wastewater treatment agent

Abstract

The invention discloses a heavy metal wastewater treatment agent which is composed of, by weight, 10-20 parts of exocarpium citris grandis, 5-10 parts of sodium carboxymethylcellulose, 8-15 parts of sodium dichloro isocyanurate, 5-15 parts of activated carbon, 5-10 parts of polymerized iron sulfate, 0.5-1 part of butyl acetate, 5-10 parts of sodium carbonate, 5-10 parts of sodium cumenesulfonate, 3-10 parts of sodium tripolyphosphate, 2-8 parts of tall oil fatty acid, 5-18 parts of peracetic acid disinfectant, 2-5 parts of lauryl betaine, 2-5 parts of octadecyl trimethyl ammonium chloride and 10-15 parts of coal ash. The heavy metal wastewater treatment effect can effectively lower content of heavy metal ions, COD and SS in wastewater; a preparation method is simple, and product cost is low; the wastewater treatment agent is short in wastewater treatment period, and wastewater treated by the agent can reach recycling standards; the wastewater treatment agent is free of toxic substance and good in discoloring effect, and water treated by the agent is free of undesirable smell.

Description

technical field [0001] The invention relates to a sewage treatment agent, in particular to a heavy metal wastewater treatment agent. Background technique [0002] As the name implies, sewage treatment agent is an additive that needs to be used in sewage treatment, such as polyacrylamide, cationic polyacrylamide, anionic polyacrylamide, nonionic, zwitterionic polyacrylamide, polyaluminum chloride, etc. in different uses It can be used as a sewage treatment agent. [0003] Polyacrylamide (Polyscrylamide) is referred to as PAM, and its molecular formula is: [CH 2 -CH(CONH 2 )] n , is a linear polymer with a molecular weight between 4 million and 20 million. The appearance of the solid product is white or slightly yellow powder, and the liquid is a colorless viscous colloid. It is easily soluble in water and easily decomposes when the temperature exceeds 120 ° C. . It has been reported in the literature that foreign researchers have found that the degradation products of po...

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
