In-situ biologically repairing method of polluted water body with composite enzyme biopromoter

Abstract

The in-situ biological repairing method of polluted water body with composite enzyme biopromoter is to throw composite enzyme biopromoter in the amount and mode determined based on pollutant quantity to the polluted water body. The work flow includes the steps of: examining the polluted water body, analyzing the polluted water amount and total pollutant amount, determining the repair plan, establishing operation platform, and repairing the water body in different stages. The present invention has the advantages of restoring water self-cleaning capacity, restoring the natural ecological environment, low ecological risk and simple operation, and is suitable for treatment on different kinds of polluted water bodies.

Description

【Technical field】 [0001] The invention relates to the technical field of environmental protection, in particular, it is a method for in-situ bioremediation of polluted water bodies using a compound enzyme bioaccelerator, which is suitable for urban slow-flow, closed-type black and odorous rivers or eutrophication Environmental governance of river courses and large areas of polluted waters. 【Background technique】 [0002] According to statistics, more than 90% of urban rivers in China are currently polluted at different levels. In order to beautify the city and create a harmonious and sustainable living environment, it is necessary to treat the polluted water body. The use of remediation in situ organisms to treat polluted water is a newly developed technology in the field of environmental protection. Purification of water bodies through absorption, transformation, removal or degradation, has the advantages of less investment, high benefits, less environmental impact, less ...

However, in order to maintain the long-term restoration effect, the existing microbial growth promoters generally contain high-efficiency bacteria that secrete biologically active substances, and are mainly used in micro-polluted water bodies such as groundwater and aquifers, as well as those affected by oil and specific organic substances. Polluted water bodies, most of the microbial growth promoters are still in the research stage, and there are few engineering examples

The bioremediation test conducted by East China Normal University in my country on urban black and odorous rivers using water purification and growth-promoting liquid produced in the United States shows that the water purification and growth-promoting liquid has a significant effect on eliminating black and odorous water bodies and increasing dissolved oxygen in water bodies. Multiple reagents are compounded, and the use and operation process is more complicated
