AI Technical Summary

Technical Problem

The prior art has problems such as gas blockage, reduced repair efficiency, and waste of energy when repairing organic polluted sites, and it is difficult to achieve efficient repair and energy conservation and consumption reduction.

Method used

Design a system including aeration wells, extraction wells, pressure monitoring wells and data acquisition systems. The flow, pressure and exhaust gas concentration are monitored and controlled in real time through the PLC controller to avoid gas blockage and over-extraction, and promote microbial repair through sustained oxygen materials after the "tailing" effect of pollutants appears.

Benefits of technology

It realizes efficient groundwater repair, avoids gas blockage and over-exhaustion problems, shortens repair time, saves energy and operating costs, and improves repair efficiency.

Abstract

The invention provides a system and method for repairing an organic pollution site, and the system comprises a functional well subsystem which comprises a plurality of aeration wells, extraction wells, pressure monitoring wells and underground water sampling monitoring wells, and the aeration wells are arranged in a main pollution area; the extraction well covers the aeration area and ensures that a circle of surrounding all the aeration wells is formed on the periphery; the aeration subsystem is used for providing aeration for each aeration well; the extraction subsystem is used for extracting pollutants from each extraction well; the data acquisition subsystem is used for acquiring and monitoring key operation parameters of each subsystem; the PLC is respectively connected with each subsystem, and is used for monitoring the key operation parameters and controlling the operation of each subsystem; and the slow-release oxygen microbial enhancement subsystem is arranged in the aeration well and the underground water sampling and monitoring well and is used for slowly releasing oxygen into underground water. The method can effectively solve the trailing effect in the later period of repairing by a single aeration-extraction process, improves the efficiency, greatly shortens the repairing time, and saves the cost.
