Abstract

The invention discloses a method for monitoring, preventing and treating underground water pollution, which comprises the following steps of: (1) setting a plurality of detection points in the range of a mining area, detecting an underground water source, recording a heavily polluted water source area and establishing an underground well; (2) sampling, detecting and analyzing underground water through an underground well, wherein comparing operation is performed, and the underground water pollution condition is analyzed; (3) determining a pollution source as a to-be-controlled site according to the pollution condition; (4) blocking the to-be-prevented and treated site by adopting a water blocking device, and then adding an underground water repairing agent into the to-be-prevented and treated site, wherein a filter wall is arranged at the downstream of the underground water source. Aiming at pollution monitoring and prevention and treatment of underground water, the method is less affected by terrain, and the prevention and treatment range can cover the whole monitoring area and the underground depth of the monitoring area; in addition, a pollution source can be detected and can be effectively treated, and prevention is carried out by adopting a filter wall.

Description

technical field [0001] The invention relates to the technical field of groundwater treatment, in particular to a method for monitoring and preventing groundwater pollution. Background technique [0002] Groundwater refers to the water that exists in the rock voids below the ground. In a narrow sense, it refers to the water in the saturated aquifer below the groundwater surface. Groundwater is an important part of water resources. Due to its stable water quantity and good water quality, it is one of the important water sources for agricultural irrigation, industrial mining and cities. With the rapid development of my country's national economy and industry, the problem of environmental pollution has become increasingly prominent. Toxic and harmful pollutants enter the underground environmental system through various channels, causing groundwater pollution. [0003] Water pollution caused by mining is a common environmental problem in mines. The mining and production activiti...
