Problems solved by technology

However, since the use of biological fillers only changes the carrier mode of microorganisms, the cultivation of microbial flora still relies on natural selection, and the domestication time is still relatively long, and because biological fillers do not have microbial selectivity, any type of bacteria and algae are It can attach and reproduce, and sometimes even contribute to sludge bulking, and it is difficult to greatly increase the degradation rate of pollutants

Embodiment 1

[0033] For the aerobic section of municipal and industrial sewage treatment, the ecological enzymes that can rapidly improve the degradation efficiency of municipal and industrial sewage treatment processes include multi-layer fiber filament structures and biological enzyme preparations; the raw materials of the biological enzyme preparations include strong bacterial flora and biological enzyme.

[0034] Among them, the multi-layer fiber filament structure such as figure 1 and figure 2 As shown, the multi-layer fiber silk structure is composed of a loose layer, a dense layer and a nutrient base layer, the dense layer is sandwiched between two loose layers, the nutrient base layer is wrapped on the surface of the loose layer and the dense layer, and the nutrient base layer The thickness of the layer is 0.15mm, the thickness of the loose layer is 4.28mm, and the thickness of the dense layer is 2.57mm.

[0035] The loose layer is composed of fiber filaments, the dense layer is a...

Embodiment 2

[0038] This embodiment is the preparation method of the strong flora of embodiment 1, specifically comprising the following steps:

[0039] (1) Phanerochaete chrysosporium, Sphingomonas, denitrifying bacteria, saccharomyces, nitrifying bacteria, Pseudomonas stutzeri, and lactic acid bacteria were respectively cultivated to a saturated state in their respective culture media;

[0040] (2) Phanerochaete chrysosporium, Sphingomonas, denitrifying bacteria, saccharomyces, nitrifying bacteria, Pseudomonas stutzeri and lactic acid bacteria obtained by step (1) are by 10.3 with the number of effective viable bacteria: The ratio of 11.1: 16.4: 18.9: 15.8: 12.6: 14.9 is used for mixed culture, and fructooligosaccharides are added to the mixed flora according to the weight ratio of (8-10): 1 during the mixed culture process. Cultivate until the total number of effective viable bacteria is no less than 32 billion cfu / g.

Embodiment 3

[0042] This embodiment is the preparation method of the multi-layer fiber filament structure described in embodiment 1, specifically comprising the following steps:

[0043] (1) The fiber filaments are assembled into sheets to obtain a loose layer;

[0044] (2) the dense layer is sandwiched between two loose layers, and then 27% of the fiber filaments are pressed into the porous honeycomb structure of the dense layer, so that the loose layer and the dense layer are connected;

[0045] (3) Immerse the product obtained in step (2) in the nutrient base solution, wrap the nutrient base layer on its surface, and dry it at 110° C. for 30 minutes.

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...
