Black odor water treatment method based on biochar immobilization composite microorganism treatment and aeration reoxygenation system of black odor water treatment method

Abstract

The invention provides a black odor water treatment method based on biochar immobilization composite microorganism treatment and an aeration reoxygenation system of the black odor water treatment method. The treatment method comprises the following steps: (1) surveying the river pollution profile, (2) performing source control and sewage interception, (3) performing aeration and reoxygenation treatment, (4) performing degradation and purification treatment by using a biochar immobilization composite microorganism system, and (5) performing comprehensive monitor and long-term dynamic assessment on the health of an urban river ecosystem. Input of energy materials is small, man-made management control is less, economical efficiency is achieved, and the cost is only 30-50% of the cost of a traditional environmental engineering technology. According to the immobilization composite microorganism ecological restoration technology, natural organisms or slightly modified organisms rather than artificial substances are utilized to purify sewage in rivers and lakes, the environmental compatibility is good, and no secondary pollution to the environment is caused; and the method can be combined with hydrophilic landscape construction, and the external forms are natural, and is more humanized.

Description

technical field [0001] The invention relates to the field of ecological water treatment of polluted water bodies, in particular to a method for treating black and odorous water bodies based on biological carbon immobilization and composite microbial treatment and an aeration and reoxygenation system thereof. Background technique [0002] Urban black and odorous water bodies are a water environment problem that the common people strongly report, which not only damages the urban living environment, but also seriously affects the image of the city. The work of urban black and odorous water treatment is highly systematic and involves a wide range of areas. [0003] There are various treatment technologies for black and odorous water bodies in urban rivers and lakes, and source control and emission reduction are the most effective means to achieve a radical cure for black and odorous water bodies. At home and abroad, a large number of online restoration technologies for urban ri...

AI Technical Summary

Problems solved by technology

The inventive method is simple and easy, and the energy consumption and investment and construction costs are low, but the process is limited to river beaches and bank slopes, and the area is limited; and the unit process adopts a conventional process, and no process adjustment is made for the black and odorous water quality, resulting in low treatment efficiency. Insufficient natural reoxygenation capacity cannot be used for effective treatment of black and odorous rivers and lakes
