曝气生物滤池在中水回用工程中应用实例

Biological aerated filter in a wastewater reuse engineering application examples

介绍曝气生物滤池(BAF)过滤工艺在哈尔滨市某住宅小区中水回用工程的运用。实际工程中BAF工艺的连续运行,BAF出水SS、BOD5、CODCr、pH、LAS、大肠杆菌总数符合回用标准,曝气生物滤池运行的反冲洗周期可定为24h,出水符合建设部颁布的《生活杂用水回用水质标准》。

The paper introduces the biological aerated filter （ BAF ） filter technology in a residential quarter in Harbin City reclaimed water reuse engineering application. Practical engineering BAF technology of con- tinuous operation, BAF BODs, CODcr, effluent SS, pH, LAS, total coliform meet reuse standard, the operation of the biological aerated filter backwash cycle can be set to 24 h, water with the Ministry of Con- struction promulgated Miscellaneous Domestic Water Reuse Quality Standards.
