高效菌群+BAF生物曝气滤池工艺在化肥厂高浓度氨氮废水处理中的应用研究

Appliced research of waste water treatment

某炼化分公司化肥厂现有污水处理系统不能满足其排放废水的处理要求,经现场调查和试验,本项目拟采用"微生物反应池+BAF生物曝气滤池"为主体工艺、通过投加"倍加清"专性菌对该厂废水进行处理。研究表明,改造后污水处理系统处理废水能达到回用水标准,且运行成本低,有利于今后推广应用。

The present effluent treatment system of one Fertilizer Plant can＇t meet the waste water discharge requirements. After field investigations and experiments, ＂microbes reaction tank ＆ BAF biologic aeration filter chamber＂ were employed as main processing and＂Bei Jiangqing＂ specific fungus was added in to treat the waste water discharged from the corporation in this project. The research indicates that the waste water treated by the effluent treatment system can meet the recycle - water standards after im- provement, and it＇ s favorable for the future popularization and application as a result of the low running cost of the system.
