Composite coagulant for treating river basin sewage with high organic matter content

Abstract

The invention discloses a composite coagulant for treating river basin sewage with high organic matter content and relates to the technical field of a composite coagulant for organic matter treatment.The composite coagulant specifically contains components as follows: deionized water, an extracting solvent A, an extracting solvent B, activated carbon A, activated carbon B, a surfactant and a foaming agent in a ratio being 100:12:18:10:15:3:1. According to the composite coagulant for treating the river basin sewage with the high organic matter content, the sewage is treated with an extractionmethod, a traditional extraction agent is improved, and the composite coagulant for the organic matter treatment is prepared; the composite coagulant integrates the decarbonization capacity of a decarbonizer for organic matter, the extraction capacity of the extraction agent for the organic matter and the adsorption capacity of activated carbon for organic molecules, and can remove the organic matter from wastewater in a large area and larger range.

Description

technical field [0001] The invention relates to the technical field of a composite coagulant for treating organic matter, in particular to a composite coagulant for treating sewage in river basins with high organic content. Background technique [0002] In the environment of modern water pollution, various water treatment methods and technologies are developed, utilized, developed and expanded by people. In water pollution, there is a kind of pollution called organic pollution, which is a carbon-containing compound ( Carbon oxides, carbon sulfides, carbonic acid, carbonates, bicarbonates, metal carbides, cyanides, thiocyanides, carboranes, metal alkyls, metal carbonyls, organic ligand complexes of metals, etc.) Or the general term for hydrocarbons and their common derivatives. When the content of organic matter in the water body is large, it will inevitably cause serious pollution to the water body, and it needs to be treated. [0003] The existing compound coagulants for o...

Problems solved by technology

[0003] The existing compound coagulants for organic matter treatment mainly include chemical treatment agents, biological treatment agents, etc., and the chemical treatment agents also contain extractants, which use extraction chemical means to separate organic matter from water, but modern extractants do not It cannot be applied to large-scale watershed sewage treatment. In the sewage treatment process, the recovery and condensation of organic matter still need to be considered. A single extraction agent cannot exert a good extraction effect, which leads to the use of extraction methods. The application of the removal method is limited

[0004] A sewage treatment composite gel material for embedding microorganisms and its preparation method disclosed in the Chinese invention patent application publication CN105523643A, although the sewage treatment composite gel material for embedding microorganisms and its preparation method uses carrageenan, polymer Acrylamide composite gel is used as an embedding agent, porous starch is used as an adsorbent as a carrier, and inorganic powder is used as an additive to embed microorganisms and be used in sewage treatment. It can effectively absorb and remove heavy metal ions and degrade organic matter. Its preparation process is simple. The cost is low, and it has market application prospects. However, the composite gel material for sewage treatment that entraps microorganisms and its preparation method do not solve the problems of recyclable organic matter and the retention of organic matter molecules in water bodies.
