活性炭纤维载体生物膜法处理洗车废水研究

Contact oxidation of car-washing wastewater with activated carbon fiber as biocarrier

为了实现洗车废水的循环使用，进行了以聚丙烯腈基活性炭纤维（PAN—ACF）为生物膜载体处理洗车废水的实验研究。以LAS、COD和NH3-N等指标考察了活性炭纤维生物膜反应器对洗车废水的处理效果。结果表明：在常温下、pH=6．5～7，当进水流量在30mL／min时，反应器达到最佳运行参数，活性炭纤维载体生物膜法对LAS、COD和NH3-N等的去除率分别达到了97％、80％和60％。出水水质完全达到《生活杂用水水质标准》（CJ／T48-99）中洗车用水主要水质指标的规定。此外，实验表明PAN—ACF作为生物膜载体具有很好的生物亲和性和再生性。

Polyacrylonitrile activated carbon fiber （PAN-ACF） was used as biocarrier to treat the car-wash- ing wastewater in order to make it recycle. LAS,COD and NH3-N were evaluated. The results suggested that at normal temperature, pH = 6.5 - 7, the reactor could operate under the optimized operating conditions at a flow of 30 mL/min,and the removal rate of LAS,COD and NH3-N was about 97% ,80% and 60% respectively. The effluent met the Miscellaneous Domestic Wastewater Quality Standard （CJ/T48-99）. In addition, the biocompatibility and regenerability performance of PAN-ACF was good in the experiment.
