Microbial sewage treating agent for deep synergistic purification of sewage and preparation method

Abstract

The invention provides a microbial sewage treating agent for deep synergistic purification of sewage and a preparation method. Anaerobic digestive bacteria-silicone colloidal particles are formed by anaerobic digestive bacteria, seaweed nutrients, silicone and a dispersing agent through mixing and granulation, meanwhile, high molecular weight polyethylene and porous ceramic powder are mixed and ground, then, denitrifying bacteria are added, a denitrifying bacterium premix is obtained, an inorganic adhesive is sprayed to the surfaces of anaerobic digestive bacteria-silicone colloidal particles,the anaerobic digestive bacteria-silicone colloidal particles covered with the inorganic adhesive and the denitrifying bacterium premix are rolled and mixed, granulation and pelletizing are performed, and the microbial sewage treating agent for deep synergistic purification of sewage is obtained. According to the method, the anaerobic digestive bacteria are immobilized through silicone and covered with a denitrifying bacterium premix film, the defect that denitrifying bacteria and anaerobic digestive bacteria have difficulty in playing a role in sewage is overcome, the removal process is simple, the removal efficiency is high, the preparation and use cost is low, and large-scale popularization and application can be realized.

Description

Technical field [0001] The invention relates to the field of wastewater treatment, in particular to the treatment of organic pollutants and nitrogen-containing pollutants in wastewater, and in particular to a microbial sewage treatment agent for deep synergistic purification of wastewater. Background technique [0002] With the development of society and economy, more and more industrial wastewater and domestic sewage have seriously polluted water bodies, damaged the ecological environment, and threatened human health and survival. Although the existing water treatment technology continues to improve, the various pollution sources make it difficult to purify thoroughly. Among them, nitrogen pollution is an important factor that causes eutrophication and anoxic water quality deterioration. In particular, ammonia nitrogen in water has the most impact on water quality. Obviously, the existing urban domestic sewage and industrial wastewater contain a large amount of organic pollutant...

Problems solved by technology

[0009] In view of the low total nitrogen removal rate of the currently widely used biological denitrification technology, it is difficult to remove the defects fundamentally, and the denitrifying bacteria and anaerobic digestion bacteria interfere with each other when the existing microorganisms treat wastewater, and it is difficult to simultaneously treat organic pollutants and containing nitrogen. The defects of nitrogen removal, there are problems such as complicated treatment process, high treatment cost and low treatment efficiency. The present invention proposes a microbial sewage treatment agent and preparation method for deep synergistic purification of wastewater, thereby effectively realizing the treatment of nitrogenous pollutants and organic pollutants. Co-processing of pollutants with high treatment efficiency and low cost
