【摘要】 某淀粉废水处理工程新建一座升流式厌氧反应器,有效容积1 700 m~3,设计处理量50 m~3,停留时间34h,设计COD进水小于12 000 mg/L,COD去除率大于80%。由于企业调试中为节省资金,没有采取由专业技术人员进行调试,造成失利,原因有:没有编制工艺调试方案或培菌计划,盲目进行厌氧反应器的工艺调试,同时加菌种污泥用水不该应用高浓度原水作培菌用水,不该用生产过程产生的黄粉作营养剂,当酸化时处理不当造成调试失利后,在专业技术人员指导下,采取措施后运行正常。更多还原

【Abstract】 Certain starch wastewater treatment project constructs an up- flow anaerobic reactor with effective volume of1700m~3,designed treating capacity 50m~3,residence time 34 h,designed influent COD less than 12000mg/L and COD treatment efficiency more than 80%.The company employed unprofessional technicians to save money,leading to failures in debugging.The reasons for this failure are lack of preparation in debugging and bacteria cultivation,testing the anaerobic reactor aimlessly,using high contention cultivation water and adopting by- product of yellow power to cultivate bacteria.The professional technicians solved the problems of acidification and the project operates normally.更多还原
