Abstract

The invention discloses an in-situ water treatment system which comprises a gas injection well, a plurality of gas phase extraction wells, a gas phase extraction device and an aeration device; the multiple gas phase extraction wells are arranged on the periphery of the gas injection well. Each gas phase extraction well is internally provided with an MBR membrane assembly, the aeration device is matched with the gas injection well and the MBR membrane assemblies and is configured to aerate the gas injection well and the MBR membrane assemblies, and the gas phase extraction equipment is matchedwith the gas phase extraction wells and is configured to extract gas treated by the MBR membrane assemblies in the gas phase extraction wells. According to the in-situ water treatment system, the gasinjection well and the MBR membrane assembly share one aeration system, so that the remediation range is large, and various pollutants can be remediated; according to the system, the MBR membrane assembly is combined with the gas phase extraction well, so that sewage treatment can be carried out in an underground water well, ground sewage treatment facilities and underground water extraction facilities are saved compared with a P & T system, and the overall structure is greatly simplified.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to an in-situ water treatment system. Background technique [0002] Extraction treatment is a traditional technique for groundwater and soil remediation. Contaminated groundwater is pumped to the surface, treated and reinjected into the ground, or discharged into surface water or sewage treatment plants. In situ bioremediation can be stimulated by reinjection because the treated groundwater can be enriched with oxygen and nutrients before it is reinjected back. [0003] Pump&treat technology (pump&treat, referred to as P&T) is to capture the underground polluted plume and pump it out of the ground, and use various treatment techniques to purify the water and use it or reintroduce it underground. The early groundwater restoration mainly used the extraction-treatment method, but the P&T treatment system was used. The sewage treatment of the P&T treatment system was mainly ca...
