Abstract

The invention discloses a light-Fenton catalytic oxidation coal chemical industry wastewater deep treatment system and a coal chemical industry wastewater treatment method thereof, relates to a coal chemical industry wastewater deep treatment system and the coal chemical industry wastewater treatment method thereof, and aims to solve the problems of high cost, low efficiency, serious sludge accumulation and poor treatment effect in the existing coal chemical industry wastewater deep treating process. The system disclosed by the invention consists of a water inlet system, a chemical inlet system, a photoreaction treatment system and a cyclic water system. Sunshine is adopted as a light source of the system; under the catalytic reaction of TiO2, except that part of pollutants can be directly decomposed, a hydroxyl complex of iron has high light absorption property, and can absorb light and perform photolysis to generate more .OH; the reaction speed is high. Illumination can also enhance the reduction of Fe<3+> and improve the concentration of Fe<2+>, and is beneficial to the catalytic decomposition of H2O2, so that the removal effect of pollutants is improved, the removal rate of COD and ammonia nitrogen reaches over 90 percent, and chrominance is also removed greatly.

Description

technical field [0001] The invention relates to the field of advanced treatment of industrial wastewater, and is a method suitable for the advanced treatment of coal chemical wastewater. Background technique [0002] In recent years, with the rapid development of my country's chemical industry, a large number of organic pollutants have entered water bodies through various channels, and some of them are difficult to biodegrade and remove, which poses a serious threat to both human beings and the environment. Wastewater discharged by coal chemical enterprises is produced during the coal processing process, including gasification wastewater, liquefaction wastewater and coking wastewater, mainly high-concentration coal gas washing wastewater. The water quality of the wastewater is complex, containing a large amount of phenols, polycyclic aromatic compounds and heterocyclic compounds, cyanide, oil, ammonia nitrogen and other toxic and harmful substances. [0003] With the gradua...
