Abstract

The invention discloses an ozone advanced oxidation system for in-situ extraction treatment of underground water. The system comprises an ozone preparation device and an oxidation reaction device. Ozone prepared by the ozone preparation device can be switched to be introduced into an injection well at a water return prevention tank of the oxidation reaction device for ozone in-situ oxidation or introduced into an ozone reaction tower of the oxidation reaction device, the ozone reaction tower is filled with a catalyst filler, and the ozone reacts with sewage pumped into the ozone reaction tower under the catalysis of a catalyst so as to remove pollutants. The ozone advanced oxidation system is reasonable in structure and convenient to operate, the treatment modes of in-situ injection and extraction treatment can be flexibly switched according to different site conditions, and the treatment efficiency of remediation of underground water pollution by an ozone oxidation process is remarkably improved.

Description

technical field [0001] The invention belongs to the field of environmental protection and relates to an ozone advanced oxidation system used for groundwater in-situ extraction treatment. Background technique [0002] With the development of society, the discharge of organic waste is also increasing, and the pollutants infiltrate vertically along the vadose zone, and migrate and spread with the groundwater flow, resulting in more and more serious soil and groundwater pollution. Since the 1960s, groundwater pollution has gradually intensified, and groundwater restoration technology has also developed accordingly. Abroad has made great progress in groundwater pollution control, and gradually developed a relatively systematic groundwater pollution control technology. Common groundwater remediation techniques can be roughly divided into three types: in-situ remediation technology, ex-situ remediation technology and natural attenuation remediation. [0003] Groundwater in-situ r...
