Because of incomplete oxidation of coal in the semi-coke production process, the semi-coke wastewater contains a large amount of coal tar and low molecular organic matters, has complex components, mainly contains coal tar substances, and mainly contains methanol, ethanol, formic acid, acetic acid, benzene, toluene, xylene, trimethylbenzene, phenol substances and the like, and contains a large amount of cyclic chain organic compounds, ammonia nitrogen and the like. The dry storage temperature in coke production is about 1000 ℃, while the dry storage temperature in semi-coke production is low (about 700 ℃). Therefore, the semi-coke wastewater contains a large amount of pollutants which are not oxidized at high temperature, and the concentration of the pollutants is about 10 times higher than that of the coking wastewater. If the sewage is directly discharged into rivers and lakes, the environment is polluted, and ammonia gas and phenol gas in the sewage are easily volatilized into the atmosphere, so that the air quality is affected. Tar in the semi-coke wastewater comprises heavy oil, light oil and emulsified oil.
In the conventional semi-coke wastewater pretreatment system, common oil-water separation devices are an oil scraping machine and an oil separation plate, and some methods of precipitation and layering are used for oil-water separation, wherein the methods have long waiting time for oil-water separation and can only simply remove heavy oil and part of light oil in water, and emulsified oil in water cannot be thoroughly treated;
