活性无烟煤过滤去除有机物的性能研究

Study on the Filtration Performance of Activated Anthracite for Removal of Organics

通过小试试验研究了活性无烟煤过滤对水中有机物的去除效果。试验结果表明,活性无烟煤过滤能有效去除浊度,出水浊度小于0.5 NTU,与传统滤料石英砂和无烟煤的过滤效果相当;反冲洗周期为6 d时,活性无烟煤过滤对TOC和UV254均能稳定去除,平均去除率分别为33.4%和43.6%;反冲洗周期为28 h的长期运行过程中,活性无烟煤过滤对CODMn和UV254均能稳定去除,平均去除率分别为47.4%和25.4%。活性无烟煤过滤稳定去除浊度和有机物的性能,对处理有机物微污染源水的传统给水水厂的过滤工艺改造具有重要意义。

Study on filtration effect of activated anthracite for removal of organics was conducted in bench scale.The results showed that filtration with activated anthracite can remove turbidity effectively.And the turbidity of effluent was below 0.5 NTU,which was similar to that by sand or anthracite.TOC and UV254 were removed stably by filtration with activated anthracite under the reverse flush period of 6d,and the removal rate of TOC and UV254 were 33.4 % and 43.6 %.CODMn and UV254 were removed stably by filtration with activated anthracite under the reverse flush period of 28 h,and the removal rate of CODMn and UV254 were 47.4 % and 25.4 %.It was suggested that activated anthracite is of significance in upgrading of water plant which are under the threaten of organics pollution.
