Underground water in-situ remediation system based on micro-nano bubbles and method thereof

Abstract

The invention discloses an underground water in-situ remediation system based on micro-nano bubbles and a method thereof and relates to the technical field of underground water remediation. The underground water in-situ remediation system comprises air inlet well devices and monitoring well devices, wherein each air inlet well device comprises an air inlet well, an intelligent control box and a nutrient box; each monitoring well device comprises a monitoring well; a micro-nano bubble aeration machine is arranged in the air inlet well; a water inlet and an air inlet are formed in one end of themicro-nano bubble aeration machine; an air outlet is formed in the other end of the micro-nano bubble aeration machine; a water quality monitoring module is arranged in the air inlet well; a plurality of air inlet well devices are respectively arranged at the upstream and the downstream of water flow in a water pollution region; and a plurality of monitoring well devices are arranged in the waterpollution region. The underground water in-situ remediation system disclosed by the invention has the advantages that real-time monitoring on quality of underground water is realized by virtue of theintelligent control box, the water quality monitoring module and a sewage quality monitoring module, specific decomposition treatment on different pollutants is realized, pollutant decomposition efficiency is improved, and specific treatment is carried out, so that influence on the original underground water environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of groundwater restoration, in particular to an in-situ restoration system and method for groundwater based on micro-nano bubbles. Background technique [0002] As an important water supply resource, groundwater plays an important role in our country's economy and society. At present, the quality of groundwater in my country is deteriorating significantly, and the pollution situation is very serious. The pollution of groundwater around industrial enterprises in some cities seriously threatens the safety of drinking water sources. [0003] The traditional groundwater aeration method injects compressed air into saturated soil and groundwater through an aeration well. The upward flow of air causes the pollutants in the soil and groundwater to decompose and volatilize, and then enters the unsaturated soil area with the airflow. However, the gas produced by the traditional aeration method enters the water body f...

Problems solved by technology

[0005] The object of the present invention is to provide a system and method for in-situ repair of groundwater based on micro-nano bubbles. Through the air inlet well device and the monitoring well device, the monitoring of the sewage quality in the polluted area and different pollutants are realized. The unique micro-nano bubble aeration treatment solves the problem that different pollutants in the polluted area cannot be treated in a targeted manner
