水解酸化—SBR工艺处理中药废水的工程实践

摘要

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.
