漂浮植物与底栖动物重建对采煤塌陷水域修复效果的研究
Study on Remediation Effect of Reconstructing Floating Plant and Zoobenthos on Subsided Water Area Caused by Coal Mining
摘要
Abstract
We carried out indoor water box test to study the removal efficiency of floating plant Hydrocharis dubia and zoob-enthos 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-con-taining nutritive salts in coal-mining-subsidence water body and sediment than the single application of M. melanioides. The com-bined 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.关键词
