Biochemical preparation used for treating electric power system domestic sewage, and preparation method thereof

Abstract

The invention belongs to the technical field of microorganisms, and discloses a biochemical preparation used for treating electric power system domestic sewage. The biochemical preparation is prepared through the following steps: 1, preparing a fermentation liquid; 2, preparing a liquid culture medium; 3, preparing a concentrate; 4, preparing a carrier; and 5, carrying out stirring and low-temperature drying. The biochemical preparation has the advantages of reasonable compatibility and strong synergism of all strains, effective utilization of ammonia nitrogen, SS and PP in wastewater, and great reduction of the content of CODs and BODs.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a biochemical preparation for treating domestic sewage in an electric power system and a preparation method thereof. Background technique [0002] Domestic sewage is the sewage produced in the process of human life, and it is one of the main pollution sources of water bodies. The amount of domestic sewage discharged by each person in the city is 150-400L per day, which is closely related to the living standard. Domestic sewage is characterized by high nitrogen, sulfur and phosphorus content, and it is difficult to treat later. People should protect water resources. China's national conditions are relatively special. The per capita water resources are small and the spatial distribution is unbalanced. With the acceleration of urbanization and industrialization in China, the demand gap for water resources is also increasing. In this context, the sewage treatme...

Problems solved by technology

Activated carbon is widely used as an important adsorbent material because of its rich pore structure and huge specific surface area, good chemical stability and strong adsorption capacity, but its cost is high

There are also non-metallic ionic minerals such as attapulgite for adsorption, but natural non-metallic minerals have the following limitations as adsorbents: natural non-metallic minerals have high density and limited specific surface area, and the surface of natural non-metallic minerals is mostly negatively charged. And directly using natural non-metallic powder ore such as clay minerals as the adsorbent will have the problem of difficult separation of solid and liquid after adsorption

From the principle of denitrification and phosphorus removal, some chemical and physical methods can effectively remove nitrogen, sulfur and phosphorus in sewage, but in general, the removal of these two methods is not complete, and the removal of nitrogen and phosphorus Biological treatment has the advantages of simultaneously removing C, S, N, P and low treatment cost

Traditional wastewater treatment methods using activated sludge to cultivate domesticated microorganisms can no longer effectively remove these pollutants. These substances have accumulated in the environment for a long time, causing great pollution to the ecological environment on which we live, and affecting human physical and mental health. bring great harm

A considerable number of industrial polluting enterprises in our country would rather be punished than invest in wastewater treatment. Even if there is a sewage treatment plant, the operation is extremely abnormal.
