Advanced industrial sewage treatment system with low environmental influence

Abstract

The invention discloses an advanced industrial sewage treatment system with low environmental influence. The system comprises a filtering mechanism and an electrolysis mechanism arranged near the filtering mechanism, wherein the filtering mechanism comprises a filter screen and a filter membrane, the filter screen is made of a metal material, the filter screen is located at an industrial sewage inlet, an adjusting box is arranged near the filter screen, a dosing box is arranged in the adjusting box, the adjusting box is connected with a filter screen and an electrolysis mechanism, the electrolysis mechanism comprises a pulse power supply and an electrode plate connected with the pulse power supply, the electrode plate is a multilateral rhombic pore plate, the electrolysis mechanism is located between the filter screen and the filter membrane, a transfer box is further arranged on the side, close to the filter membrane, of the electrolysis mechanism, a backflow mechanism and a reverse osmosis mechanism are arranged near the filter membrane, and the backflow mechanism is connected with the filter membrane and the adjusting box. According to the invention, 95% or more of the water in raw waste liquid is separated, the rest of the pollutants in a solid state form are separated, each pollution index of treated wastewater is significantly degraded, and full-automatic unattended automation can be achieved.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to an industrial sewage advanced treatment system with low environmental impact. Background technique [0002] Industrial wastewater includes production wastewater and production sewage, which refers to wastewater and waste liquid generated in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. of water. [0003] In the wastewater industry, industrial wastewater is the most harmful to the environment. Among them, the wastewater containing toxic and harmful substances and heavy metals produced by the electroplating industry in the chemical industry, the wastewater in the processing industry, and the spraying industry are the most harmful. Traditional membrane filtration, biochemical and other methods exist. Due to the problems of large initial ...

Problems solved by technology

[0003] In the wastewater industry, industrial wastewater is the most harmful to the environment. Among them, the wastewater containing toxic and harmful substances and heavy metals produced by the electroplating industry in the chemical industry, the wastewater in the processing industry, and the spraying industry are the most harmful. Traditional membrane filtration, biochemical and other methods exist. Due to the problems of large initial investment, high treatment costs, and high requirements for the stability of raw water, the traditional treatment methods for industrial wastewater are mainly physical and chemical methods and biochemical methods. For treatment, anaerobic / itchy technology is the main treatment. This method requires a huge investment in the early stage, and the fluctuation of the composition of the wastewater source in the later stage should not be too large, otherwise the effect of the wastewater after treatment will drop significantly. The physical and chemical methods are mainly neutralization, precipitation, filtration and centrifugation. Treatment process, the advantage of this method is that the initial investment is small, but the disadvantages are high treatment cost and high maintenance cost

[0004] At present, there is a lack of a low-cost sewage treatment system that can achieve the maximum degradation of pollutants after fully automatic treatment of wastewater, and at the same time, the volatility of raw water pollution components has little impact on the treated water samples.
