Abstract

The invention discloses a mixed sewage treating agent which is prepared from the following raw materials in parts by weight: 10-20 parts of pomelo peel, 5-10 parts of attapulgite, 8-15 parts of dodecyldimethylbenzyl ammonium chloride, 5-15 parts of graphene, 5-10 parts of polyferric sulfate, 0.5-1 part of butyl acetate, 5-10 parts of sodium carbonate, 5-10 parts of sodium xylene monosulfonate, 3-10 parts of sodium tripolyphosphate, 2-8 parts of tall oil fatty acid, 5-18 parts of peroxyacetic acid disinfectant, 2-5 parts of lauryl betaine, 2-5 parts of octadecyltrimethyl ammonium chloride and 10-15 parts of fly ash. The sewage treating agent can effectively lower the contents of heavy metal ions, COD (chemical oxygen demand) and SS (suspended sediment) in the sewage. The preparation method is simple, and the product cost is lower. The mixed sewage treating agent has the advantage of short sewage treatment period, and the treated sewage can reach the cyclic utilization standard. The sewage treating agent is free of toxic substances, and has favorable decolorization effects; and the treated water does not have any stink.

Description

Technical field [0001] The invention relates to a sewage treatment agent, in particular to a mixed sewage treatment agent. Background technique [0002] As the name suggests, sewage treatment agent 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 activi...
