Laboratory carbon tetrachloride separation treatment system and treatment process thereof

Abstract

The invention discloses a laboratory carbon tetrachloride separation treatment system and a treatment process thereof. The laboratory carbon tetrachloride separation treatment system comprises an activated carbon filter box with S-shaped adsorption tanks and a treatment region with a nano-bubble generator. The activated carbon filter box and the treatment region are arranged in an aeration reaction box and partitioned through a partition plate and are communicated through a flow guiding pipe. The S-shaped adsorption tanks are filled with activated carbon filler and internally provided with suspension plates, and one end of each S-shaped adsorption tank is provided with a water outflow pipe. One end of the aeration reaction tank is provided with a residual liquid inflow pipe. The laboratory carbon tetrachloride separation treatment system and the treatment process thereof have the advantages that due to the adoption of an oxidation, aeration and adsorption joint treatment mode, the treatment efficiency is high, and the high removal effect is achieved for high-concentration volatile substances containing tetrachloride laboratory residual liquid; in the adsorption process of activated carbon, the activated carbon filter tank is divided into the multiple S-shaped adsorption tanks through the suspension plates, the laboratory residual liquid containing carbon tetrachloride flows in an S-shaped path, the contact time of the residual liquid and the activated carbon is prolonged, meanwhile, the contact area of the residual liquid and oxygen is increased, and treatment efficiency is improved.

Description

technical field [0001] The invention belongs to an environmental protection treatment technology, relates to the field of treatment of high-concentration organic carbon tetrachloride-containing laboratory residual liquid, in particular to a laboratory carbon tetrachloride separation treatment system and a treatment process thereof. Background technique [0002] Carbon tetrachloride (CCl 4 ) is a synthetic low-boiling organic chlorinated hydrocarbon (specific gravity 1.591g / 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, so since 1979 it has been listed by the U.S. EPA as a "priority control pollutant in groundwater containing carbon tetrachloride", and it has also been listed as 68 kinds of p...

Problems solved by technology

[0025] However, due to the complex geological structure, when the injected air encounters a complete rock formation zone, a loose broken zone or a curved deformation zone, it is difficult for the injected air carrying volatile organic compounds to penetrate the above-mentioned geological structure, and when the injected air meets the above-mentioned geological structure, the air Large resistance will greatly increase the energy consumption of the equipment

It is even less effective for pollutants that are neither volatile nor biodegradable
