摘要
采用厌氧/好氧/生物脱氨/混凝沉淀工艺处理煤化工废水,设计总处理量为360m3/h。4个多月的调试运行结果表明,该工艺运行稳定,耐冲击负荷能力强,当进水平均COD为2 141 mg/L、总酚为391 mg/L、氨氮为92 mg/L时,处理后出水COD<100 mg/L、总酚<10 mg/L、氨氮<15 mg/L,出水水质达到《污水综合排放标准》(GB 8978—1996)的一级标准。
The anaerobic/aerobic/biological ammonia removal/coagulation sedimentation process was used to treat the wastewater from coal chemical industry. The design capacity is 360 m^3/h. The commissioning operation result for over four months shows that this process operates stably and has strong resistance to shock loading. When the average influent COD, total phenol, ammonia nitrogen are 2 141 mg/L, 391 mg/L and 92 mg/L respectively, the average effluent COD, total phenol, ammonia nitrogen are less than 100 mg/L, 10 mg/L and 15 mg/L respectively, reaching the first class criteria specified in httegrated Wastewater Discharge Standard （ GB 8978 - 1996 ） .
