Abstract

The invention relates to a sludge-based micro-pore framework capturing mesh wall and a method for repairing heavy-metal pollution of underground water and belongs to the technical field of environmental engineering. The invention aims at providing the sludge-based micro-pore framework capturing mesh wall which takes modified sludge as a foundation and the method for repairing the heavy-metal pollution of the underground water, which can be used for carrying out targeting reduction and adsorption aiming at a target on heavy-metal pollutants in the underground water. The sludge-based micro-pore framework capturing mesh wall provided by the invention is characterized in that a capturing mesh wall is composed of a plurality of stereoscopic capturing modules; each stereoscopic capturing module is formed by a core region and a membrane wall through compounding, wherein each core region is a sludge-based micro-pore framework hard ball carrying nano Fe (0) and each membrane wall is a sludge-coal pitch carbonized membrane; the sludge-based micro-pore framework hard balls carrying the nano Fe (0) are filled into the sludge-coal pitch carbonized membranes to form the cylindrical stereoscopic capturing module.

Description

technical field

[0001] The invention relates to a sludge-based microporous frame trapping net wall and a method for repairing groundwater heavy metal pollution, belonging to the technical field of environmental engineering. Background technique

[0002] Groundwater pollution is an important environmental issue related to the national economy. Pollutants produced by human activities seep into the ground, leading to deterioration of groundwater quality. In recent years, groundwater pollution in various parts of our country has become increasingly serious. According to statistics, 60% of our country's groundwater environment is in serious or relatively serious pollution. Typical groundwater pollution includes: saline water intrusion, nitrate pollution, petrochemical product pollution, landfill seepage pollution. Among them, the heavy metals lead, chromium, cadmium, manganese, arsenic and copper are the main polluting elements. At present, the typical groundwater pollution re...
