Embodiment 1

[0050] Such as figure 1 Shown, be the laboratory carbon tetrachloride separation treatment system structure schematic diagram of the present invention, can find out, comprise the activated carbon filter case 11 that contains S-shaped adsorption tank 4 and have the treatment area of ​​nano-bubble generator 1, two Those placed in the aeration reaction box 2, separated by a partition 5, and communicated through the guide tube 3; wherein the S-shaped adsorption tank 4 is filled with activated carbon filler 8 and is provided with a suspended plate 9, one end of the S-shaped adsorption tank 4 A water outlet pipe 10 is provided; one end of the aeration reaction box 2 is provided with a residual liquid inlet pipe 6 .

[0051] Such as image 3 Shown is the front view of the laboratory carbon tetrachloride separation and treatment system of the present invention. It can be seen that the S-shaped adsorption tank 4 is formed by vertical dislocation of suspended plates 9, and the number o...

Embodiment 2

[0057] Utilize the above separation system to process the laboratory raffinate containing carbon tetrachloride. First, the carbon tetrachloride raffinate enters the aeration reaction box 2 through the raffinate inlet pipe 6, and the hydrogen peroxide reaction reagent passes through the hydrogen peroxide filling pipe 6- 1 enters the aeration reaction box 2 and reacts with the carbon tetrachloride residue; at the same time, the external air enters the nanobubble generator 1 through the air inlet pipe 1-3, and the high-speed rotor impeller 1-1 rotates at a speed of 3000-9000 rpm Rotating at a speed of 1 minute, the micro-bubbles generated by the microporous aeration head 1-2 are crushed into bubbles with a diameter of 10-600 nanometers, which are evenly diffused into the reaction box and mixed with tetrachloride in the aeration reaction box 2. Carbon fully reacts.

[0058] The treated solution enters the activated carbon filter box 11 through the guide pipe 3. Since the activated...

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...
