A kind of volatile organic compound polluted water treatment system

Abstract

A volatile organic compounds polluted water treatment system is characterized in that a spray system is mainly composed of a spray pipe net and a plurality of nozzles uniformly arranged on the spray pipe net, and the spray pipe net is arranged all over an open space at the upper portion of a water tank; an aeration system is mainly composed of a fan, an air supply pipeline and an aeration pipe net, the aeration pipe net is uniformly arranged at the bottom of the water tank, the fan goes through the air supply pipeline and the water tank, enters the water tank and is connected with the gas inlet of the aeration pipe net, and the aeration pipe net is uniformly provided with a plurality of aerators; a water collecting groove for collecting water flow sprayed by the nozzles on the spray pipe net is arranged between the spray pipe net and the aeration pipe net, and the right end of the water collecting groove is provided with a water draining port; and a front side baffle wall extending toward a rear sidewall is arranged between the front sidewall and the bottom wall of the water tank, and a rear side baffle wall extending toward a front sidewall is arranged between the rear sidewall and the bottom wall of the water tank. The volatile organic compounds polluted water treatment system has the advantages of simple structure, convenient maintenance, low treatment cost and high separation efficiency.

Description

technical field [0001] The invention belongs to the technical field of water pollution treatment, in particular to a volatile organic compound pollution water treatment system. Background technique [0002] As an important part of human living space, groundwater provides high-quality freshwater resources for human beings. However, with the increasingly serious environmental pollution in our country, the underground pollution caused by human activities has expanded from point to surface. In addition to its own pollution, groundwater has become an important medium of soil pollution. At present, the organic pollution of groundwater has become a research hotspot at home and abroad, among which the pollution of volatile chlorinated hydrocarbons (such as carbon tetrachloride) is particularly noticeable. [0003] Carbon tetrachloride is a colorless transparent liquid with a special smell. Its boiling point is low at 76.8°C. It is slightly soluble in water and easily soluble in mo...

Problems solved by technology

[0003] Carbon tetrachloride is a colorless transparent liquid with a special smell. Its boiling point is as low as 76.8°C. It is slightly soluble in water and easily soluble in most organic solvents. It is not easy to volatilize in the underground environment and has almost no biological decomposition. Therefore Once the groundwater body is polluted by this substance, it is difficult to self-purify and eliminate it, but it is easy to volatilize in the air. This substance has been listed as one of 129 "blacklists of water priority pollutants" by the United States, and 68 "by China" In the Blacklist of Priority Control Pollutants in Water", it is a toxic and harmful substance with "three causes" (carcinogenic, teratogenic, and mutagenic) effects, which can damage the liver. As a non-aqueous organic substance, it can be found in groundwater Medium and long-term existence, seriously threatening the health of drinkers

[0004] The existing carbon tetrachloride water pollution treatment system usually uses heating to separate carbon tetrachloride and water. Such a system is not only complex in structure, cumbersome in maintenance process, but also expensive in treatment
