Abstract

The invention relates to a plant microorganism combination remediation soil and a shallow groundwater organic pollutant system, comprising a treating groove, plant remediation floating beds, an embedding immobilized microorganism processing film, a star-type aerating apparatus and a tail gas treatment device, wherein the system is remediated by the treating groove, the plant remediation floating beds, the embedding immobilized microorganism processing film, the star-type aerating apparatus and the tail gas treatment device; the treating groove is supported by a mesh supporting wall; the plantremediation floating beds are sampled mutually connected; the embedding immobilized microorganism processing film is fixed at a position 1.5m away from the bottom of the treating groove; and the star-type aerating apparatus is connected with the tail gas treatment device by a pipeline. The advantages are as follows: with relative simple design, the system is more convenient to carry out; the groundwater with organic pollutants has the characteristics of high efficiency, economy and non secondary pollution; the range for remediating underwater is wide; the variety of the removable pollutant isvery wide; and the system is applied to treating municipal sewage and domestic sewage.

Description

【Technical field】

[0001] The invention relates to the technical field of soil and groundwater pollution restoration, in particular to a plant-microbe joint restoration system for organic pollutants in soil and shallow groundwater. 【Background technique】

[0002] Groundwater pollution has become an environmental problem that cannot be ignored. At present, many soils and shallow groundwater in our country are seriously polluted by organic matter. The types of pollutants are complex, the concentration far exceeds the standard, and the existence of free phase is even detected. The pollution situation has far exceeded the natural attenuation and repair ability of the soil and groundwater system. Among the three types of soil and groundwater pollution, organic pollution has surpassed heavy metal pollution and radioactive pollution, and has become the main form of groundwater pollution. Among them, the pollution and remediation of organic chlorinated olefins in groundwater have bec...
