- 摘要:
- 针对制药废水中含高浓度COD和氨氮的水质特点，建造了一套处理规模为1 500 m3/d的混凝沉淀/两级水解酸化/缺氧/好氧/膜生物反应器处理设施。通过控制合适的污泥接种、驯化条件，逐步提高进水量，顺利完成工程调试。系统对COD、氨氮、TP和SS的去除率分别为97.4%、99.3%、43.1%和96.4%，COD、氨氮、TP和SS的平均浓度分别从8 171.4、173.7、0.95和235.8 mg/L降到214.6、1.3、0.54和8.6 mg/L，pH从7.2升到7.5，出水COD、氨氮、TP、SS和pH的相对标准差分别为23.2%、15.4%、66.0%、32.2%和7.8%，出水水质达到《污水综合排放标准》（GB 8978—1996）三级标准和浙江省《工业企业废水氮、磷污染物间接排放限值》（DB 33/887—2013）标准，直接运行费用为7.36元/m3。
- Abstract:
- According to the characteristics of high concentration COD and ammonia nitrogen in the pharmaceutical wastewater, a set of coagulation sedimentation, two-stage hydrolytic acidification, and anaerobic/aerobic membrane bioreactor treatment facility with capacity of 1 500 m3/d was built. The commissioning of combined process is completed by controlling suitable conditions of sludge inoculation and acclimation, and gradually increasing inflow. The removal rates of COD, ammonia nitrogen, TP, and SS were 97.4%, 99.3%, 43.1%, and 96.4%, respectively. The average concentration of COD, ammonia nitrogen, TP, and SS in the wastewater decreased from 8 171.4 mg/L, 173.7 mg/L, 0.95 mg/L and 235.8 mg/L to 214.6 mg/L, 1.3 mg/L, 0.54 mg/L and 8.6 mg/L, respectively. The value of pH in the wastewater increased from 7.2 to 7.5. The relative standard deviations of effluent COD, ammonia nitrogen, TP, SS and pH were 23.2%, 15.4%, 66.0%, 32.2% and 7.8%, respectively. The effluent quality meets the third level of criteria specified in the Integrated Wastewater Discharge Standard (GB 8978-1996) and the Indirect Discharge for Emission Limitation of Nitrogen and Phosphorus for Industrial Wastewater (DB 33/887-2013), with the direct operating cost of 7.36 yuan/m3．
