| titleOfInvention | A photo-Fenton catalytic oxidation coal chemical wastewater advanced treatment system and its method for treating coal chemical wastewater |
| abstract | A photo-Fenton catalytic oxidation coal chemical wastewater advanced treatment system and a method for treating coal chemical wastewater, which relate to a coal chemical wastewater advanced treatment system and a method for treating coal chemical wastewater. The invention aims to solve the problems of high cost, low efficiency, serious sludge accumulation and poor treatment effect in the existing deep treatment process of coal chemical industry wastewater. The system of the invention is composed of a water inlet system, a drug inlet system, a light reaction treatment system and a circulating water system. The light source of the present invention adopts sunlight, and under the catalysis of TiO2 , except that some pollutants can be directly decomposed, the hydroxy complex of iron has better light absorption performance, and absorbs photolysis to produce more OH, The reaction speed is fast. Illumination can also strengthen the reduction of Fe 3+ and increase the concentration of Fe 2+ , which is beneficial to the catalytic decomposition of H 2 O 2 , thereby improving the removal effect of pollutants. The removal rate of COD and ammonia nitrogen can reach more than 90%, and the chromaticity has also improved significantly. Great removal. |
