摘要
为了解兰州银滩湿地公园对黄河水质的净化作用,对兰州银滩湿地公园不同河段的水流中氨氮、亚硝酸盐氮、总磷和氟化物的含量进行了测定。测定结果表明:湿地对水中TP的净化效果较好,去除率达到79.6%;对NH4+-N的净化效果次之,去除率达到了40.0%;对F-和NO2--N的净化作用一般。
In order to get the purifying effect of Lanzhou Yintan Wetland Park on the water qua-lity of Yellow River, the contents of ammonia nitrogen, nitrite nitrogen, total phosphorus and fluoride ion in different stream segments in wetland were determined. The results showed that the purification effect of TP in water was very good and its removal rate was 79.6%. The removal rate of NH4＋-N reached 40.0%, while the purification effects of F-and NO2--N were general.
