生物膜法在玻璃纤维废水处理中的研究

Study on Treatment of Glass Fiber Wastewater by Biofilm Process

玻璃纤维废水COD值较高,可生化性差,目前常规生化处理方法对该废水的处理效果较差。为提高污水处理能力,降低污水处理厂投资及运行费用,本文以MBR法在某玻璃纤维公司污水厂内进行污水深度处理及回用的试验研究。探讨MBR法处理玻璃纤维废水的可行性,并进一步实验分析HRT及温度对其效果的影响。结果表明:MBR法处理后出水COD基本稳定在100~150 mg/L之间,MBR法深度处理玻璃纤维废水比较可行。停留时间HRT为8~10 h时MBR效果最佳,温度与MBR出水COD成反比关系,水温为20~25℃时处理效果较佳。

Glass fiber wastewater has high COD value and poor biodegradability, the conventional biochemical treatment method has poor effect on the wastewater. In order to improve the wastewater treatment capacity and reduce the investment and operation cost of wastewater treatment plant, study on treatment and reuse of glass fiber wastewater by MBR method was carded out. The feasibility of MBR treatment of glass fiber wastewater was discussed, and the effect of HRT and temperature on the treatment effect was further analyzed. The results show that MBR is more feasible for glass fiber wastewater treatment, and suitable residence time HRT is 8 - 10 h. The temperature is inversely proportional to the effluent COD of MBR, and suitable treatment temperature is 20℃.
