Sewage treatment agent and method for treating black and odorous water body by sewage treatment agent

Abstract

The invention discloses a sewage treatment agent. The sewage treatment agent is prepared from a high molecular polymer flocculating agent, an inorganic flocculating agent, a fungus nutrient substance,an aerobic complex microbial flora, a facultative complex microbial flora, an anaerobic complex microbial flora and an inorganic nano-material; a method for treating a black and odorous water body comprises the following step: directly adding the sewage treatment agent into the black and odorous water body or adding a coating treatment agent prepared from the sewage treatment agent into the blackand odorous water body. The sewage treatment agent provided by the invention can be used for effectively managing the black and odorous water body, has an ideal management effect and does not cause damages to the environment and the water quality does not rebound after management. The method for treating the black and odorous water body is simple and efficient to operate and is green and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of environmental protection and treatment, and relates to a sewage treatment agent, in particular to a sewage treatment agent and a method for treating black and odorous water bodies. Background technique [0002] The black and odorous state is an extreme state of water body, and its own characteristics are also very different from other states. Its physical and chemical environment is characterized by strong reduction, extremely serious organic and inorganic pollution, and the water body has peculiar smell, which is no longer suitable for the survival of aquatic organisms. The aquatic vegetation is degraded or even extinct. The food chain is broken, the food web is fragmented, the ecosystem structure is seriously unbalanced, and its functions are seriously degraded or even lost. At present, most urban rivers in our country have evolved into black and smelly rivers. In many cities in our country, the organic polluti...

Problems solved by technology

[0003] At present, the methods for treating black and odorous water bodies include: external source blocking, internal source control, water quality purification, hydrodynamic improvement and ecological restoration, etc. However, the existing black and odorous water body treatment methods cannot completely solve the water pollution problem, not only treating It takes a long time, the treatment method is complicated, consumes a lot of manpower and material resources, and the water body after treatment is easy to rebound, and although artificial dosing of chemicals can achieve the treatment effect in a short period of time, it will destroy the ecological environment. In addition to comprehensive treatment, microorganisms are usually used to treat black and odorous water bodies

[0004] Although the use of microorganisms for sewage treatment has the advantages of harmlessness, stability, and high efficiency, it has high requirements on pH, temperature, solvents, etc., and is not easy to store, which greatly limits its wide application in wastewater treatment.
