摘　　要：针对焦化废水生物脱酚系统溶解氧过低的问题,通过淘汰原有竖管曝气装置,采用自制微孔曝气装置,使曝气量完全达到工艺要求,同时污泥沉降比得到提高,相比成熟的尼龙网微孔曝气装置,节约成本,便于维护。The self-made microporous aeration device was adopted as a substitution for the original stand pipe aeration device in the coking biological dephenol system in order to obtain a uniform aeration quantity and meet the requirements. After several years of operation, the aeration quantity achieved the technological requirements completely. The sludge settlement ratio increased as well. Comparing with the mature nylon nets microporous aeration device, the self-made pore aeration device saved cost and was easy to maintain.
