摘要
通过室内水箱实验,研究了漂浮植物水鳖(Hydrocharis dubia)与底栖动物田螺(Margarya melanioides)对采煤塌陷水域水体以及底泥间隙水污染物的去除效果。结果表明:水鳖和田螺组合对采煤塌陷养殖水体及底泥氮磷等营养盐的去除效果优于田螺单独作用的;覆盖面积10%的水鳖和田螺组合对水体中TN、TP、NH_4^+-N、NO_3^--N以及NO_2^--N的去除效果较好,去除率分别达到了55.56%、77.50%、65.12%、46.43%、66.67%;同时该组合对底泥间隙水中的TN、TP也有一定的去除作用。
We carried out indoor water box test to study the removal efficiency of floating plant Hydrocharis dubia and zoobenthos Margarya melanioides on pollutants in coal-mining-subsidence water body and sediment interstitial water. The results showed that the combined application of H. dubia and M. melanioides had better removal effects on the N-containing and P-containing nutritive salts in coal-mining-subsidence water body and sediment than the single application of M. melanioides. The combined application of 10% cover area of H. dubia and M. melanioides obtained better removal effects on TN,TP,NH_4~＋-N,NO_3^--N and NO_2^--N in the water body,and their removal rate reached 55.56%,77.50%,65.12%,46.43% and 66.67%,respectively;this combined application also had a certain removal effect on the TN and TP in sediment interstitial water.
