The invention provides a coal chemical wastewater biological treatment system based on sludge catalytic ozonation and a treatment method thereof. The system comprises an anoxic / aerobic biological treatment system for first-grade predenitrification, a sludge catalytic ozonation multiphase reaction system and a second-grade anoxic denitrification / aerobic biological treatment system. The method comprises the following steps: subjecting to-be-treated coal chemical wastewater to anoxic / aerobic biological treatment of first-grade predenitrification, subjecting one part of treated sludge to refuxing and the other part of the treated sludge to ozone catalytic digestion, mixing a supernatant generated by ozone catalytic digestion with the sewage obtained by anoxic / aerobic biological treatment of first-grade predenitrification, and subjecting the obtained mixture to second-grade anoxic denitrification / aerobic biological treatment so as to obtain effluent water, wherein tail gas generated by catalytic digestion is used for aeration treatment for second-grade anoxic denitrification / aerobic biological treatment. According to the invention, a sludge catalytic ozonation multiphase reactor is adopted, so highly-efficient and low-cost oxidation digestion of the sludge can be realized, and functions of a novel method are guaranteed to be realized.

The invention discloses a sludge reduction method by using ozone. The sludge reduction method comprises the following steps of (1) filtering of sewage; (2) aeration treatment of sewage; (3) settling and separation of the sludge; (4) ozone treatment of the sludge. The sludge reduction method has the advantages that the structure is simple, and the practicality is strong; by utilizing the ozone technique, the net sludge increasing amount is equal to the inorganic sludge amount in the sewage treatment process, so that the purpose of reducing the remained sludge is realized; in addition, the working efficiency is high, the energy loss is low, the secondary pollution is avoided, the reduction effect of the sludge is obvious, and the comprehensive utilization rate is effectively improved.
