摘要
生物转盘(筒)是处理中、小流量废水的一种较经济有效的方法,本试验采用新型填料式生物转筒作为关键设备处理食品加工废水,结果表明:系统对COD、BOD5、SS和LAS有显著的去除效果,当进水COD为1200~1700mg/L,BOD5为600~1200mg/L时,出水水质可以达到广东省地方标准《水污染物排放限值》(DB44/26-2001)中的二级标准。
Biological rotating disk (biological drum reactor) is a kind of effective and economic method of treating medium or small discharge wastewater. The experimental test was conducted on a pilot scale. It showed that using new biological drum reactor to treat food industry wastewater is feasible. When the influent COD is 1200 ~1700 mg/L, and BOD5 is 600 ~ 1200 mg/L, the removal efficiency of COD, BOD5, SS and LAS are all high. The effluent quality can meet the Grade Ⅱ of Discharge Limits of Water Pollutants (DB44/26-2001) set by Guangdong Province.
