Problems solved by technology

[0004] 1. The production cost of traditional packing is high and the performance is low;
[0005] 2. Traditional packing has low specific surface area and poor adsorption capacity;
[0006] 3. Traditional fillers have poor degradability of pollutants, unstable biological phase, and single types of microorganisms
[0007] The above-mentioned fillers are less effective in treating high-concentration organic wastewater, such as high-concentration COD, ammonia nitrogen and other pollutants in livestock and poultry wastewater

Embodiment Construction

[0044]In line with the principle of using waste to treat waste and utilizing resources, the present invention preferentially selects corresponding landfills to transform the cultivation conditions, so as to meet the requirements for temperature, oxygen concentration and organic nutrients in the cultivation of multi-biological phase microbial bacteria micelles; at the same time The culture cycle is also the key to the selection of multi-biophase microbial micelle fillers. After aerobic, facultative, and anaerobic oxygen concentration gradient changes, a type of soil-type microbial community with strong shock load resistance, rough living conditions, and strong degradation ability is formed under long-term domestication of high-concentration organic solutions.

[0045] According to the principle of co-situ nitrification and denitrification and anaerobic ammonium oxidation, the "multi-biophase microbial micelle" after screening and cultivation is used as the substrate, relying on ...

Abstract

Provided is a cultivation method for multiple-biophase microbial zoogloea used for waste water treatment, comprising the following steps: establishing an environment for cultivating multiple-biophase microbial zoogloea; screening the multiple-biophase microbial zoogloea; selecting an implantation carrier for the multiple-biophase microbial zoogloea; and domesticating strains.

Description

technical field [0001] The invention belongs to the technical field of ecology and environmental protection, and in particular relates to a method for cultivating multi-biological-phase microbial bacteria micelles for wastewater treatment. Background technique [0002] The bacteria micelles in the prior art, such as the micelles existing in the activated sludge or the bacteria micelles grown on the filler by the biofilm method, are all formed by the growth of metabolically active microbial sludge in the biological treatment system, The inoculation environment of this kind of bacteria micelles is simple, without artificial screening steps, the implantation carrier is single, and the controllability of domestication is poor, and the biological phase formed is often a single aerobic phase or anaerobic phase. [0003] The core of conventional biological filter bed treatment is the microbial implantation filler. The fillers in the prior art are generally divided into three types ...
