Multiple sewage processing material

Abstract

The invention relates to a multiple sewage processing material, which comprises the following raw materials by weight: 3-10 parts of polyvinyl ester, 5-7 parts of heavy liquid paraffin, 3-5 parts of attapulgite, 3.2-6 parts of maleic anhydride grafted polypropylene, 4-9 parts of sodium sulfate, 2.5 parts of 8 parts of active carbon, 1-5 parts of sodium benzenesulfonate, 4-8 parts of cobalt oxide, 12-18 parts of alumina, 1.5-7 parts of sodium dodecanesulphonate, 6-11 parts of montmorillonite, 6-14 parts of carboxymethyl methyl cellulose, 1-5 parts of ferric hydroxide, 1.2-3 parts of anatase titanium dioxide, 6-13 parts of polyethyleneimine and 6-10 parts of aluminum sulfate. The multiple sewage processing material has good processing effect, can better absorb particles, and can reduce the metal ion in sewage with little usage amount.

Description

technical field

[0001] The invention relates to a multiple sewage treatment material. Background technique

[0002] With the progress of society and the development of modern technology, pollution is becoming more and more serious, especially water pollution, which is quite difficult to control. Water pollution is mainly due to various exogenous substances discharged by humans. After entering the water body, it exceeds the self-purification of the water body itself. A phenomenon of the extent to which the action can be tolerated. Sewage may seep into groundwater and pollute it. Adding a reducing agent to the existing wastewater to reduce metal ions has a single treatment effect and cannot treat the wastewater well. Contents of the invention

[0003] In view of the deficiencies of the prior art, the problem to be solved by the present invention is to provide a multi-layer sewage treatment material with good treatment effect, which can not only adsorb particles well, but a...
