Abstract

Abstract

Owing to the high chemical oxygen demand(COD), organic nitrogen content, and toxicity, the treatment effectiveness of conventional process for pesticide chemical wastewater is relativity low. Treatment of pesticide wastewater becomes a concerned issue in water treatment processes. Aiming at the problems that the condensate wastewater generated by the pesticide wastewater was not properly treated by conventional biological treatment processes, this project proposed a reconstruction scheme by adopting advanced biological treatment process using engineering bacteria synergism and dual-membrane process including ultrafiltration(UF) membrane and reverse osmosis(RO) membrane. After the reconstruction, stable wastewater treatment performance with improved rejection of the COD and TN(with the rejection rate of 85% and 67%, respectively) was observed in the system, and the start-up time of the biochemical system was also shortened. Besides, the dual-membrane process guaranteed the quality of the effluent with COD<500 mg/L, TN<70 mg/L, and NH₃-N<45 mg/L, reaching the standard requirements of the downstream sewage treatment plant. In addition, the total operation cost of the project was 2.77 RMB/ton. The application of the advanced biological treatment process using engineering bacteria synergism, combined with the dual-membrane process guaranteed the efficient treatment of the condensate wastewater from the pesticide chemical plant.
