Microbial water body in-situ treatment flora purification body and sewage treatment method adopting same

Abstract

The invention relates to a microbial water body in-situ treatment flora purification body and a sewage treatment method adopting the same. The microbial water body in-situ treatment flora purificationbody comprises the following components in parts by mass: 30-40 parts of a flora adsorption body, 2-7 parts of a microbial compound bacteria solution, 3-7 parts of a carbon source, 40-60 parts of clay, 2-7 parts of rice bran and 2-8 parts of bottom mud. According to the microbial water body in-situ treatment flora purification body, microbial florae can be better fixed to river sediment to be treated, the situation that the microbial florae are easily washed away and dispersed by water flow like bacterial liquid is avoided, and therefore the microbial florae can fully react with harmful pollutants in the sediment to absorb, degrade and convert the pollutants in a river. Therefore, the black and odorous water body and the black and odorous bottom mud are locally reduced and improved at theoriginal position, a better sewage treatment effect is further obtained, finally, an original water area ecological circulation system is restored, the self-purification capacity of the water area isrestored, and the treatment effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of microbes, in particular to a bacterial group purification body for in-situ treatment of microbial water bodies and a sewage treatment method using the bacterial group purification body. Background technique [0002] In recent years, with the continuous development of economy and society and the continuous improvement of people's living standards, a large number of pollutants produced in production and life have been released into water bodies without treatment, causing serious environmental pollution. One of the important factors that lead to the occurrence of pollution is the existence of a large number of suspended solids in the water body. There are a large number of soluble and insoluble substances in these suspended solids. These substances exist in the entire water body of the river. The concentration of nutrient salts such as , N, and P, and the accumulation of insoluble solid substances pollute th...

Problems solved by technology

At present, physical restoration methods mainly include technologies such as sediment dredging, sediment dilution and scouring, water diversion, mechanical algae removal, hydraulic dispatching, gas extraction, and air blowing. These technologies have the advantages of clear purpose and quick results, but at the same time There are shortcomings such as large amount of engineering, high cost, and incomplete treatment. This method is often used to deal with sudden water pollution. It has the advantages of fast speed and good effect, but the treatment effect is not good, and it cannot fundamentally solve the problem.

The chemical remediation method mainly uses various chemical agents to kill algae, and adds iron salts to promote the precipitation of phosphorus, etc., but the chemical remediation method requires a large amount of chemicals and is likely to affect water quality; bioremediation is a remediation technology with good development prospects , make full use of the absorption, degradation and transformation of plants, aquatic animals and microorganisms in the water body, minimize the concentration of harmful pollutants in the water body, and at the same time have the advantages of low treatment costs and reduce secondary pollution, but there are also microorganisms In the process of putting into use, it is easy to lose with the flow of water and soil in the river, which makes the treatment effect poor and other difficulties, making it difficult to promote the bioremediation method
