Problems solved by technology

[0020] However, the permeable reaction wall is easy to be blocked, the natural environmental conditions such as the redox potential in the laboratory are easily damaged, and the operation and maintenance are relatively complicated. In addition, the cost of bimetallic systems and nanotechnology is high, these factors hinder the permeability. Further development and vigorous promotion of the reaction wall

Abstract

The invention discloses vehicular underground water carbon tetrachloride treatment equipment which consists of a buffer pool, a water distribution device, a reaction column, a heating device, a drainage pipe, a silt discharge pipe, a movable frame and a control system, wherein the water distribution device conveys the to-be-treated underground water to the center of the bottom of the reaction column from the bottom of the buffer pool; the heating device heats the lower end of the reaction column; the to-be-treated underground water reacts with fresh air at the bottom of the reaction column; the to-be-treated underground water slowly flows from bottom to top and is completely reacted after reaching the top of the reaction column; the generated clear water is discharged from the upper part of the reaction column along the drainage pipe; the carbon tetrachloride gas is discharged from the top of the reaction column; and the settled sludge is discharged from the bottom of the reaction column. The vehicular underground water carbon tetrachloride treatment equipment disclosed by the invention has the advantages of good treatment effect on carbon tetrachloride, low energy consumption and small floor area and is suitable for treating the underground water rich in carbon tetrachloride.

Description

technical field [0001] The invention belongs to the field of groundwater pollution treatment devices, in particular to a vehicle-mounted groundwater carbon tetrachloride treatment equipment. Background technique [0002] Carbon tetrachloride (CCl 4 ) is a synthetic low-boiling organic chlorinated hydrocarbon (specific gravity 1.591 g / cm 3 , boiling point 77°C), slightly soluble in water. Foreign studies have shown that carbon tetrachloride is a typical liver poison. When it is in high concentration, it will first affect the central nervous system, and then affect the liver and kidney. It has persistence, long-term residue and bioaccumulation in the environment. Therefore, it has been listed by the US EPA as a "priority control pollutant in laboratories containing carbon tetrachloride" since 1979, and it has also been included in 68 species by my country. "Priority pollutants in water" list. [0003] In the 1970s, due to the large-scale manufacture and use of pesticides, s...
