River course water body and sediment in-situ remediation process using enzyme-bacterial microbial agent

Abstract

The invention discloses a river course water body and sediment in-situ remediation process using an enzyme-bacterial microbial agent, wherein the in-situ remediation process comprises: 1, raw materialselection; 2, bacterial activation; 3, bacterial fermentation; 4, enzyme and bacterial compounding; 5, sediment tedding; 6, sediment backfilling; and 7, microbial agent activation. According to the present invention, the remediation agent is formed by compounding Pediococcus acidi lactici, Enterococcus faecalis, Bacillus amyloliquefaciens, Pichia farinosa and Dekkera anomala based on five beneficial biomass such as hemicellulase, xylanase, amylase, pectinase and Arabic gum enzyme, is a strain having good adaptability to river course water body and sediment, has good organic matter degradationeffect, and can effectively remove COD, ammonia nitrogen, total phosphorus, total nitrogen and various organic pollutants from river course water bodies so as to improve the water quality and the substrate environment of the water body, easily achieve the natural construction of the aquatic ecosystem, and achieve the in situ restoration of water bodies and sediments.

Description

technical field [0001] The invention relates to the technical field of water environment protection, in particular to an in-situ restoration process of an enzyme+bacteria microbial agent for river water and bottom mud. Background technique [0002] With the rapid development of my country's economy, my country's water environment problems have become increasingly prominent, and urban and rural water environments have encountered unprecedented threats. Existing surveys have shown that most of the country's water environment ecology has lost its basic functions, resulting in serious degradation of the river due to pollution and ecosystems. The water quality of the river is basically at V or worse. The main pollution indicators are COD, ammonia nitrogen, total phosphorus, and total nitrogen, causing most of the river water to turn black and smelly, resulting in a severe environmental and ecological situation, seriously affecting ecology, production and life safety. Therefore, ...

AI Technical Summary

Problems solved by technology

[0004] For river water bodies with COD, ammonia nitrogen, total phosphorus, and total nitrogen as the main pollutants, although the method of adding compound enzyme bioactivators or adding functional microbial flora has achieved certain results, there are still some problems. The effect of compound enzyme bioactivators cannot last long, and cannot effectively remove organic pollutants such as ammonia nitrogen, total phosphorus, and total nitrogen. However, the method of adding functional microbial flora faces weak microbial metabolic activity and environmental tolerance in the application process. Low strength and other issues
