Organic synthesis wastewater low-emission system

Abstract

The invention relates to the technical field of wastewater, in particular to an organic synthesis wastewater low-emission system which comprises a shell, the shell is divided into an upper free radical oxidation zone, a photocatalytic reaction zone and a lower free radical oxidation zone from top to bottom, and a central rotating shaft is vertically arranged in the shell; the central rotating shaft penetrates through the upper free radical oxidation zone, the photocatalytic reaction zone and the lower free radical oxidation zone, a plurality of electrolysis electrodes are arranged in the upper free radical oxidation zone around the central rotating shaft, a cleaning device is arranged between the electrolysis electrodes and the central rotating shaft, double layers of photocatalytic nets are arranged in the photocatalytic reaction zone, and an ultraviolet light source is arranged between the two layers of photocatalytic nets. The lower free-radical oxidation zone is connected with a medicament box through a pipeline, and stirring blades are arranged at one end, positioned in the lower free-radical oxidation zone, of the central rotating shaft. Compared with the prior art, by arranging a plurality of wastewater treatment areas, the rate of generating active free radicals is increased, the organic matter decomposition capacity effect is more than two times that of ozone, the cost is low, and the energy consumption is low.

Description

technical field [0001] The invention relates to the technical field of wastewater, in particular to a low-discharge system for organic synthetic wastewater. Background technique [0002] With the rapid development of the country's economy, people's living standards are getting better and better, and the level of industrialization is getting higher and higher. Industrial sewage and domestic wastewater are increasing rapidly. In the process of sewage treatment, there will be an aerobic pool, which is to The sewage in the pool is oxygenated to provide the required oxygen for the microorganisms in the aerobic pool. This link is called aeration. Aeration is an important process link in the sewage treatment process. At present, there are two types of aeration, mechanical aeration and blast aeration, but most sewage treatment plants will choose an aeration method to aerate the aerobic tank, sometimes due to insufficient aeration, some aerobic organic matter is not fully decomposed,...

[0002] With the rapid development of the country's economy, people's living standards are getting better and better, and the level of industrialization is getting higher and higher. Industrial sewage and domestic wastewater are increasing rapidly. In the process of sewage treatment, there will be an aerobic pool, which is to The sewage in the pool is oxygenated to provide the required oxygen for the microorganisms in the aerobic pool. This link is called aeration. Aeration is an important process link in the sewage treatment process. At present, there are two types of aeration, mechanical aeration and blast aeration, but most sewage treatment plants will choose an aeration method to aerate the aerobic tank, sometimes due to insufficient aeration, some aerobic organic matter is not fully decomposed, affecting aeration The efficiency, so that the sewage does not achieve the expected effect in the process of treatment
