Abstract

Abstract:

The stainless steel microporous membrane elements were selected to conduct cross-flow filtration experiments to filtrate coal dust wastewater under the mine and hazardous waste solution(oil and salt wastewater) in machining industry respectively. The results showed that the interception efficiency of solid particles in coal-containing wastewater by microporous membrane elements with filtration accuracy of 1 μm was up to 98%. For the oily and salt wastewater system containing colloidal solid particles, the suspension and NH₃-N content were reduced by 73.9% and 54% after filtration by 1 μm stainless steel microporous membrane element.

Key words: metal microporous materials, cross-flow filtration, industrial wastewater, membrane separation

摘要：

采用不锈钢微孔膜元件进行错流实验，分别对含煤废水、机加工行业的危废溶液进行过滤。结果表明：过滤精度为1 μm的金属微孔膜元件对含煤废水中固体颗粒的拦截效率可达98%。对于含有胶体状固体颗粒物的含油含盐废水体系，经1 μm不锈钢微孔膜元件过滤后，悬浮物可降低73.9%，NH₃-N降低54%。
