摘要：

Treatment of an electronic polished wastewater was experimentally investigated in this study. The polished wastewater is characterized by high suspended solid concentration, presence of biorefractory macromolecule organic compounds and low biodegradability. So it is very difficult to treat with traditional biochemical methods. In the present work, combined chemical and biological methods synergistically utilized to treat the wastewater. A new combined treatment consisted of chemical flocculation, anoxia and sequencing batch reactor (SBR) process. Experimental tests were conducted to determine the effectiveness and the optimum operating conditions of the combined menthod. Test results clearly demonstrated the synergistic advantages of the combined treatments. The treated water could reach the national and local standards CODcr less than 90mg/L, when the original wastewater CODcr was 2000-4000 mg/L. The results of the study present scientific basis and experimental data for treating polished wastewater.
