Ecological enzymes that can rapidly increase the density and degradation efficiency of beneficial bacteria in the reaction environment

Abstract

The invention relates to the technical field of bio-film treatment wastewater, in particular to an ecological enzyme substance capable of quickly improving the density and degradation efficiency of beneficial bacteria in a reaction environment. The ecological enzyme substance comprises a multilayer cellosilk structure and a bio-enzyme preparation, wherein raw materials of the bio-enzyme preparation include strong bacterial colonies and bio-enzyme; the multilayer cellosilk structure comprises loose layers, a compact layer and a nourishment base layer; the compact layer is clamped between the two loose layers; the surfaces of the loose layers and the compact layer are wrapped with the nourishment base layer. In the wastewater, the amount of the multilayer cellosilk structure is 0.5-1 m<2> / ton and the amount of the bio-enzyme preparation is 2-20 g / ton; by utilizing the special multilayer cellosilk structure, nourishment balance of mineral salts and artificially adhered preferred strains and bio-enzyme, the bacterial colonies in the wastewater can be quickly multiplied and a purpose of efficiently degrading pollutants can be achieved.

Description

technical field

[0001] The invention relates to the technical field of biofilm treatment of sewage, in particular to an ecological enzyme that can rapidly increase the density and degradation efficiency of beneficial bacteria in the reaction environment. Background technique

[0002] In the domestic municipal sewage treatment and industrial wastewater treatment, the activated sludge method is still the main treatment method. The activated sludge method uses granular sludge as a biological carrier, relies on the regulation of pollutants in the sewage and process parameters, and artificially cultivates the required microorganisms. Therefore, the activated sludge method has the advantages of long domestication time, low treatment efficiency, and large civil construction area. , high sludge production and other shortcomings. At present, some sewage plants use biological fillers such as volcanic rocks and glass balls instead of granular sludge as biological carriers. The biolog...
