常用过滤材料对微细颗粒过滤性能的研究

摘要

通过实验手段对几种过滤材料的阻力、过滤效率进行了研究。结果表明，目前常用的过滤材料对超细颗粒物的除尘效果并不理想，尚有很大的提升空间。%From the view point of water pol ution status of smal-sized towns in our country, the paper analyzes the prob-lems existed in the sewage treatment of the smal-sized towns, such as poor understandings, a limited fund support, backward operation mode and the imperfect relevant laws and regulations. The paper puts forward the countermeasures on the develop-ment of sewage treatment in smal-sized towns.
