摘要
以西安市兴庆湖为研究对象,实验研究进水浓度对水平潜流人工湿地净化城市湖泊水体的影响。实验参照排入西安市兴庆湖的混合污水的水质,测定了进水浓度对化学需氧量、总氮、总磷、氨氮的去除效果。结果表明:随着水力停留时间的变化,进水浓度对CODcr、TP、NH3-N的去除影响不大,CODcr、TP、NH3-N的去除率分别为79.77%,81.61%,50.66%,有较好的去除效果。而进水浓度对TN的去除有明显影响,去除率仅为27.12%。
Taking the Xingqing Lake in Xi＇an as research object,the paper studied the effects of influent concentration on the artificial and depuration of urban lakes. Consulting the sewage of Xingqing Lake in Xi＇an,the removal efficiency of constructed wetland was investigated for COD、TN、TP、NH3-N at Influent concentration. The results indicate： With increasing hydraulic retention time ,influent concentration has little effect,the removal rates of CODcr,TP,NH3-N in the systems are 79. 77% ,81. 61% and 50. 66% respectively. Influent concentration has an obvious effect on TN,the removal rates of TN is 27. 12% .
