摘要
在充分利用原有废水处理构筑物的基础上,通过技术改造,采用水解酸化+厌氧/好氧+MBR工艺处理含高NH3-N的化工废水。运行结果表明,改造后的废水处理工艺,在进水COD为1 000 mg/L,NH3-N质量浓度为200mg/L时,出水COD稳定在100 mg/L,NH3-N质量浓度在15 mg/L以下,出水水质稳定并达到了设计的排放要求。
The original wastewater treatment process was transformed based on the primary structures. Hydrolytic acidification, anaerobic, aerobic and MBR processes were used to treat high concentration NH3-N wastewater. The results indicated that the effluent concentration of COD and NH3-N were less than 100 mg/L and 15 mg/L when the influent concentration of COD and NH3-N were 1 000 mg/L and 200 mg/L respectively. The water quanlity of the effluent was stable and reached the design requirement.
