Problems solved by technology

However, during the disinfection process, halogen elements (mainly chlorine) will react with some natural organic matter (NOMs, natural organic matters) in the water to form some "three-caused" substances harmful to the environment and human body, called disinfection by-products, which have been identified so far The main disinfection by-products are: trihalomethane, halogenated acetic acid and halogenated acetonitrile, etc. These disinfection by-products are extremely carcinogenic, teratogenic and mutagenic

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0032] refer to figure 1 As shown, a method for treating Escherichia coli in sewage plant tail water of the present invention comprises the following steps: introducing sewage plant tail water into a bioretention tank, which is filled with anthracite as a filler; arbuscular mycorrhiza The fungi are inoculated into aquatic plants at the seedling stage to construct an arbuscular mycorrhizal fungus-aquatic plant symbiotic system; the arbuscular mycorrhizal fungi-aquatic plant symbiotic system is planted in a bioretention tank.

[0033] Specifically, after the arbuscular mycorrhizal fungus is inoculated into the aquatic plants at the seedling stage, the cultivation period is not less ...

Abstract

The invention relates to a method for treating escherichia coli in tail water of a sewage plant. The method comprises the following steps of: introducing the tail water of the sewage plant into a bioretention pond filled with anthracite serving as a filler; inoculating arbuscular mycorrhizal fungi into aquatic plants in a seedling stage to construct an arbuscular mycorrhizal fungi-aquatic plant symbiotic system; and planting the arbuscular mycorrhizal fungi-aquatic plant symbiotic system in the bioretention pond. According to the method of the invention, the escherichia coli in the sewage is intercepted and eliminated in a manner of combining physical action and biological action.

Description

technical field [0001] The invention relates to the technical field of tail water treatment of sewage plants, in particular to a method for treating Escherichia coli in the tail water of sewage plants. Background technique [0002] With the rapid development of the economy and the rapid increase of the population, my country's water demand continues to expand, and the urbanization process accelerates while increasing the burden of water use in some areas. Water environmental pollution also limits the total amount of water resources to a certain extent. . Sewage recycling is one of the important ways to alleviate the shortage of water resources. After the sewage is biochemically treated, the residual pollutants and pathogenic microorganisms in the effluent are further removed to meet the reuse water standard, which can be directly or indirectly reused for daily production and municipal miscellaneous use. [0003] In water treatment and sewage treatment, chlorination disinfe...
