Abstract

The invention relates to an integrated ex-situ repair system for underground water polluted by volatile organic compounds. The system comprises an underground water extracting device, a dissolved organic matter blow-off tower, a tail gas dehumidification device and a gas-phase organic matter biological activated carbon adsorption reactor, wherein the underground water extracting device, the organic matter blow-off tower, the tail gas dehumidification device and gas-phase organic matter biological activated carbon adsorption reactor are arranged in turn; the underground water extracting deviceis connected with the organic matter blow-off tower through a pipeline; and the blow-off tower, the tail gas dehumidification device and the biological activated carbon adsorption reactor are connected by pipelines. The system has the advantages of complete design, convenient implementation, high-efficiency and energy-saving treatment of the underground water polluted by the volatile organic compounds without secondary pollution, wide underground water repair range, capability of removing various pollutants and wide application.

Description

【Technical field】 [0001] The invention relates to the technical field of groundwater, in particular to an integrated ex-situ restoration system for groundwater polluted by volatile organic compounds. 【Background technique】 [0002] my country's groundwater pollution is very serious, among which organic pollution has surpassed heavy metal pollution and radioactive pollution, and has become the main form of groundwater pollution. The research and practice of groundwater organic pollution control technology in foreign countries has a long history and has achieved more results; while domestic research on groundwater organic pollution control is mostly in the laboratory research stage, and there is an urgent need for engineering practical technology that can effectively control groundwater pollution. and methods. [0003] At present, the remediation of organic pollutants in groundwater is mainly through in-situ chemical oxidation and biological methods: advanced oxidation and bi...
