Transverse pollutant-removing biological pipe applied to remediation of polluted underground water

Abstract

The invention belongs to the technical field of treatment of polluted underground water and more particularly provides a transverse pollutant-removing biological pipe applied to remediation of polluted underground water. The transverse pollutant-removing biological pipe comprises an outer pipe, an inner mesh pipe and a filled inner core which are successively arranged from outside to inside; the filled inner core is covered by the inner mesh pipe and is sleeved in a pipeline of the outer pipe; holes are formed in the outer pipe; the inner mesh pipe is a tubular metal wire mesh; the filling material of the filled inner core is resin. According to the transverse pollutant-removing biological pipe applied to remediation of polluted underground water, the filled inner core is covered by the inner mesh pipe and is sleeved in the pipeline of the outer pipe; the transverse pollutant-removing biological pipe is capable of enhancing the underground water collection effect and conveniently mounting and replacing the active materials.

Description

technical field [0001] The invention belongs to the field of groundwater pollution restoration, in particular to a horizontal decontamination biological pipe used for the restoration of polluted groundwater. Background technique [0002] Pollutants produced by humans in production and life are directly or indirectly discharged into the groundwater environment, causing groundwater pollution. Currently, remediation technologies for groundwater pollution include permeable reactive wall (PRB) technology, circulating well technology (GCW) and so on. PRB technology requires a lot of excavation and a large amount of engineering. Its reactive wall is prone to blockage, it is difficult to replace the repair plan, and the repair cost is high. It is only suitable for repairing shallow groundwater. GCW technology is limited by local hydrological and water quality conditions, and has little effect on the treatment of pollutants whose gravity is greater than water. The engineering volume...
