Abstract

The invention relates to a sewage treatment agent. The sewage treatment agent is prepared from the following components: chitosan solidified tannin, a sodium bentonite-loaded microbial agent, graphene, a biological compound enzyme, an organic-inorganic flocculant, a flocculation aid, sodium hydrogen sulfite, coconut shell powder and sawdust. The sewage treatment agent disclosed by the invention ishigh in bioactive substance stability and high in activity, has good adsorption capacity, flocculation capacity and biodegradation capacity, is applied to river sewage and aquaculture wastewater treatment, can effectively remove most of heavy metals, complexes and organic matters in sewage, effectively reduce the nitrogen and phosphorus content in sewage, and purifiy water, and is efficient and environmentally friendly; and no secondary pollution is caused.

Description

technical field [0001] The invention relates to a sewage treatment agent and its preparation method and application. Background technique [0002] In recent years, intensive aquaculture and animal husbandry have developed rapidly in China. However, most aquaculture in my country adopts closed waters. The self-purification ability of water bodies is far lower than the eutrophication speed of water bodies, and the water environment has been greatly damaged. Due to the application of feed, the accumulation of animal carcasses and animal manure, the proportion of organic matter and nitrogen and phosphorus in the breeding wastewater is extremely high, and the antibiotics in the feed fed for a long time make the animals collectively develop drug-resistant bacteria to attack humans and animals. Animal husbandry wastewater mainly includes livestock urine, residual feces, feed residues, etc., which are characterized by high pollutant concentration, high suspended solids, high nitroge...
