摘要
成都某中药产业园中药废水具有水量水质变化大、成分比较复杂的特点。采用改良式预处理与"UASB+接触氧化"生化处理以及"微絮凝+曝气生物滤池"深度处理结合的工艺。稳定运行之后,出水水质达到《中药类制药工业水污染物排放标准》(GB 21906—2008)中污染物最高允许排放浓度的一级标准。介绍了工艺流程、主要构筑物的设计参数,可为同类工程设计提供借鉴。
The wastewater of a Chinese traditional medicine industrial park in Chengdu was characterized as complex composition and great fluctuation of both water quality and flow. The modified pre- treatment and UASB/contact oxidation process combined with advanced treatment process （micro-floccu- lation/biological aerated filter） were applied. After stable operation, the effluent quality could meet the first level criteria in the Discharge Standard of Water Pollutants for Pharmaceutical Industry Chinese Traditional Medicine Category （ GB 21906 - 2008）. The process flow of the project and the design parameters of the main constructures were introduced, and it could provide a reliable reference for the design of similar projects.
