新型生物转筒处理食品生产废水的试验研究

Study on a New-Type Biological Drum Reactor Treatment of Food Industry Wastewater

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.
