CASS工艺处理中药废水

Treatment of the Traditional Chinese Medicine Wastewater by CASS Process

根据中药制药废水水质,设计采用间歇运行的CASS工艺。运行结果表明,处理后出水COD、BOD_5、SS分别为36-88 mg/L、19-28 mg/L、36-56 mg/L,达到《污水综合排放标准》(GB8978-1996)二级标准及《渭河水系(陕西段)污水综合排放标准》二级标准。该工艺具有工程投资和运行费用低,处理效率高,剩余污泥量少等优点。

Traditional Chinese medicals wastewater is treated by GASS based on the wastewater quality. The running results show that COD, BOD5 and SS can reach 36 - 88 mg/L, 19 - 28 mg/L and 36 - 56 mg/L respectively, meeting the requirements of the second class specified in ＂Comprehensive Wastewater Discharge Standard＂（GB8978 - 1996） and ＂Weihe River System（the Shanxi section） Comprehensive Wastewater Discharge Standard＂. The process has the advantages of low engineering investment and low operational cost, high efficiency, low residual sludge, etc.
