Description

Hydraulic soil pollution flushing system

This creation relates to a hydraulic soil pollution flushing and remediation system, especially a system for remediation of contaminated soil, which uses a pipe body inserted into the contaminated groundwater for extraction to separate or remove pollutants dissolved in water, and then treats the The water is drained back to the pipe body and the soil is washed again, so as to achieve the purpose of recycling the land and regulating the groundwater.

Common groundwater treatment methods such as air extraction, oxidation, extraction and electrokinetic methods, natural biological treatment or chemical treatment (such as the addition of sodium hydroxide, calcium oxide, and calcium carbonate), etc., not only require long treatment time and require Higher costs. In order to achieve better practicability, related companies have developed different improvement systems to improve the effectiveness of on-site groundwater pollution control.
