微絮凝双层滤料过滤处理含油废水试验研究

Experimental Study on Micro-flocculation and Double-bed Filtration for Treating Oil-containing Wastewater

针对机电和机械加工行业排水中含油废水的特性 ,提出了微絮凝双层滤料过滤法处理工艺。通过实验 ,肯定了其良好的除油效果 ,并对影响除油率的因素进行了分析讨论 。

Based on the insight into the characteristics of oily effluents of mechanical and electrical machining industries, micro flocculation plus double bed filtration technology was chosen for the effluent treatment. This paper reports on the laboratory experiment conducted to determine the applicability of the technology in terms of filtration velocity, dosage of flocculants, and other design constraints. The experimental results showed effectiveness of the technology for removing oils.
