Problems solved by technology

The application of strong acid and strong chlorine, on the one hand, has a certain application effect of sewage treatment, but it brings secondary pollution of sludge. Aeration itself strengthens the forced feeding of gas, and solves the "standard" The most serious problem is that it leaves more polluting and smellier problems. The actual cases of pure biological bacteria treatment of sewage have not really appeared in sewage treatment. The reason is that they all show Because the flora is not strong enough

Abstract

The invention relates to the technical field of sewage treatment, and particularly discloses a composite active microbial agent for water treatment, and an application thereof. The composite active microbial agent for water treatment is characterized in that the composite active microbial agent comprises a composite flora and an inducer which are mixed into a whole, and the composite flora is composed of nitrifying bacteria, denitrifying bacteria, bacillus, pseudomonas, activating enzyme, photosynthetic bacteria and a sweetness strain; and the inducer is composed of amino acids, yeast extract,chitin, chitosan oligosaccharide and glucose. The product disclosed in the invention has the characteristics of simplicity in preparation, low production cost, strong flora survivability, easiness inculture, rapidness in propagation, strong adaptive capacity to the environment, natural evolution, meeting the requirements of sewage treatment, and strong applicability.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a composite active bacterial agent for water treatment and its application. Background technique [0002] In recent years, due to frequent human activities, the amount of sewage discharge has increased. Sewage mainly includes domestic sewage, aquaculture sewage and industrial wastewater. Among them, the composition of industrial sewage is relatively complex, especially a large number of artificially synthesized compounds entering the environment. These substances are mainly ammonia nitrogen, sulfide and phosphorus-containing compounds. Due to the complexity of the structure of these substances, traditional wastewater treatment methods have not been effective. These pollutants are removed; in addition, with the acceleration of social industrialization, a large amount of refractory organic pollutants are discharged into the environment, such as polycyclic aromatic hydroca...
