摘要
以邯郸市滏阳河为水源，研究了生物砂滤池对微污染源水中有机物的去除规律及其影响因素。结果表明，生物砂滤池对微污染源水中的CODMn和TOC均有很好的去除效果，对TOC的去除率为18％～25％；温度对CODMn去除效果有较大的影响，常温下对CODMn的平均去除率为30％，低温下的平均去除率则降至15．9％；氨氮以及原水中CODMn的含量对CODMn的去除效果均有一定影响。此外，考察了微污染源水中CODMn与COD的相关性，结果表明两者呈明显的线性关系，生物砂滤池对COD的去除率可达33％～48％。
The removal rules of organic matter in micro-polluted source water by the biological sand filter and the influencing factors were studied using the Fuyang River as source water. The results show that the biological sand filter can remove TOC and CODMn effectively in the micro-polluted source water; the removal rate of TOC is 18% -25%. The change of temperature affects the removal of CODMn ; the average removal rate is 30% at ordinary temperature and 15.9% at low temperature; the content of ammonia nitrogen and CODMn in the source water has some influence. The test also shows that CODMn and COD have nice linear correlations, the removal effect of COD can reach 33% -48%.
