水解酸化—SBR工艺处理中药废水的工程实践

Engineering practice of the treatment of traditional Chinese medicine wastewater by hydrolysis acidification—SBR process

针对中药废水的水质特点,采用水解酸化—SBR工艺处理中药废水。运行结果表明,出水CODCr、BOD5、SS分别为16～96、16～18、8～28 mg/L,水质满足《污水综合排放标准》(GB 8978—1996)的一级标准要求。该工艺投资少,运行费用低,每吨废水处理费用合计仅为0.76元。

Based on the water quality characteristics of traditional Chinese medicine wastewater,it has been treated by hydrolysis acidification—SBR process. The running results show that its CODCr,BOD5 and SS could reach 16-96,16-18 and 8-28 mg/L,respectively,meeting the first class of Integrated Wastewater Discharge Standard（GB8978—1996）. The process has the advantages of low engineering investment and low operational cost. The total cost of wastewater treatment per ton is only CNY 0.76.
