新型高效净水器处理生活污水研究

A NEW HIGH-EFFICIENT FILTER FOR SANITARY SEWAGE TREATMENT

以聚丙烯纤维滤、自制活性炭和陶瓷为滤芯,组合3级材料滤芯构造新型高效竹炭净水器处理生活污水设备。研究污水在净水器中的适宜停留时间,考察净水器处理污水的浊度、p H、CODMn、NH3-N等效果。结果表明,在净化器体积流量为30 L/h情况下,其适宜水利停留时间140 min,浊度、CODMn和NH3-N去除率分别为89%、68%、42.5%,p H呈弱碱性。出水水质符合GB/T 18920-2002和GB 5084-92要求。

The new filter with splendid alkene fiber filter, homemade activated carbon and ceramic as filter element was applied to deal with sanitary sewage. Through the study on optimal retention time for sewage in the purifiers, the efficiency of the purifiers for treating sewage on turbidity, pH, CODw and ammonia nitrogen was carefully investigated. The experimental results showed that, under the condition of 30 L/h flow, hydraulic retention time was 140 min, and the removal rates of turbidity, CODmn and ammonia nitrogen were 89%, 68% and 42.5%, respectively, pH presenting weakly alkaline. Effluent water quality met the requirements of GB/T 18920-2002 and GB 5084-92.
