A kind of sewage treatment agent its preparation method and application

Abstract

The invention relates to a sewage treatment agent. The sewage treatment agent includes the following components: chitosan solidified tannin, sodium bentonite load agent, graphene, biological complex enzyme, organic-inorganic flocculant, flocculant aid, sodium bisulfite, coconut shell powder and wood chips . The biologically active substance of the sewage treatment agent of the present invention has strong stability, high activity, good adsorption capacity, flocculation capacity and biodegradation capacity, and can be used in the treatment of river sewage and aquaculture wastewater, and can effectively remove most of the heavy metals and complexation in sewage. It can effectively reduce the nitrogen and phosphorus content in the sewage, purify the water body, be efficient and environmentally friendly, and will not cause secondary pollution.

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...
