Abstract

The invention relates to an ecological restoration device for underground water polluted by heavy metals and organic matters. The ecological restoration device comprises an underground water pumping pipeline, an internal electrolysis section, a biochemical treatment section, a clarified water outlet section and an underground water drainage pipeline which are sequentially arranged in a sewage treatment direction, wherein the internal electrolysis section comprises an internal electrolysis box body, and further comprises an internal electrolysis water outlet area, an internal electrolysis treatment area and a water inlet and gas distribution area which are sequentially arranged in the internal electrolysis box body from top to bottom; the internal electrolysis water outlet area and the internal electrolysis treatment area are separated by a heavy metal filtering assembly equipped with cation exchange resin; a plurality of internal electrolysis filler balls are added into the internal electrolysis treatment area; each internal electrolysis filler ball comprises a hollow spherical shell internally provided with an internal electrolysis filler; and micropores enabling to-be-treated sewage to be in full contact with the internal electrolysis filler are further hermetically formed in the hollow spherical shells. Compared with the prior art, the underground water body polluted by heavy metals and organic matters can be effectively restored; the whole device does not need to adopt chemical reagents; and the device is good in ecological environmental protection property and treatment effect.

Description

technical field [0001] The invention belongs to the technical field of groundwater pollution restoration, and relates to an ecological restoration device for groundwater polluted by heavy metals and organic matter. Background technique [0002] With the rapid expansion of the city, the discharge of urban sewage is caused. Due to insufficient capital investment, the construction of the pipe network is relatively lagging behind, and the maintenance is not timely. With the overflow of rainwater, it will cause groundwater pollution and seriously affect the urban ecological environment. Therefore, the society attaches great importance to the remediation of groundwater pollution, especially the remediation of groundwater contaminated by organic matter. [0003] At present, domestic groundwater pollution control methods include physical control, chemical remediation, electrokinetic remediation, extraction treatment and other technologies. However, these technologies all have thei...
