Study On Environment Hormone Pollution In Weihe River Watershed Area (Pnase Of Xian) And Pollution Control Strategy

Wetlands- called kidney of the earth is one of the three largest ecosystems in the global As environmental pollution and human being destruction, the natural cycle of wetlands ecosystem is endangered So study wetlands and protection wetlands is one of the important problems that concerned by people. The paper study pollution situation of environment hormone and strategy on Weihe River watershed area (phase of Xian) wetlands water pollution control. At the same time, the paper provides basis on wetlands pollution control.In this paper general idea, type and function of wetlands were expounded systematically at first. Recognition and understanding of wetlands system is deepened The classification to Xian wetlands and ascertain Xian wetlands total area, distribution is the first time in Xian. Environment hormone pollution situation about Xian wetlands water inrecert years was investigated thoroughly. According to the fact,34 wetlands-water's environment hormone pollution situation were monitored on-the-spot and achieved many basis datas which has high reference value. On the basis of analysis and evaluation, the constructed wetlands imitate device was established for experimental study on Hg, Pb, ArOH and LAS four hormone pollutant disposition. The experiment achieved relative satisfied results: the removing efficiency is 76.04%(Hg), 87.04%(Pb), 93.98%(ArOH), 95.10%(LAS). Technical support for removing environment hormone by constructed wetlands was provided in the paper. The strategy of protect Xian wetlands was proposed from sides of strengthen construction wetlands natural protection area and conscious of wetlands protection, developing and protecting wetlands water resource etc..The results of study fill in the blank of Xian wetlands research and provide important materials for study and protection of Xian wetlands. The fruitful results has better practical value.
