摘要
采用气浮-二相厌氧-延时曝气为主体的处理工艺,结合清水回流稀释,处理柠檬酸废水,废水处理规模为1000m3/d,进水中COD为12000mg/L,BOD5为3000mg/L,SS为3500mg/L,出水达到GB8978-1996一级排放标准,工程投资和运行费用较低。
Citric acid wastewater was treated by air-floatation-two-phase anaerobic-extended aeration process integrating dilution of clear water recirculating with treating scale of 1000m^3/h, influent quality: COD=12000mg/L, BOD5=3000mg/L and SS=3500mg/L; the effluent reached the first class discharge standard GB 8978-1996; furthermore, its engineering investment and opearation fee were lower.
