摘要
采用多效蒸发-生化组合工艺,设计并建造了处理水量400m3/d的甲硝唑工业废水污水处理设施。对该工程各单元设施的运行状况进行了8次采样分析。运行结果表明:该工艺组合合理,耐负荷冲击性强,处理效率高。最终排放口出水平均化学需氧量(CODCr)质量浓度为73mg/L,氨氮质量浓度为13.8mg/L,出水水质完全达到《污水综合排放标准》(GB8978—1996)中一级排放标准的要求。
Multi-effect evaporation combining with biochemical process is designed and founded to treat wastewater from metronidazole production with water treatment capacity of 400 m3/d. In order to gain further information on the running status of each unit, eight times of sampling analysis have been carried out. The running results show that it can reach higher treatment efficiency for treating this kind of wastewater, and the treatment efficiency of the technology is stable and tolerable in shock load. The mass concentration of average CODcr, ammonia nitrogenin effluent at the final outlet are 73 mg/L, 13.8 mg/L, respectively. The quality of effluent can completely meet the requirement of class 1 of Comprehensive Discharge Standard of Sewage GB 8978--1996.
