摘要
平阴湿地示范区的建立主要是对污水处理厂的中水进行进一步深度处理,并考虑湿地的中水净化效果及生态环境恢复作用。此文采用二维水质模块对山东平阴县湿地示范区进行水质模拟研究,得湿地对主要污染物CODcr的衰减率约为3.4%,对中水有较好的净化效果。通过此次研究发现湿地水质净化示范效果良好,为南水北调沿线中水回用及生态修复提供依据。
The purpose of establishing Pinyin artificial wetland demonstration area was to give an advanced treatment of the reused water that from the sewage plant,and it also taken the effect of wetland in water purification and in eco-environment restoration into account.In this paper two-dimensional model was used to simulate water quality of Pinyin.The decay rate of CODcr was about 3.4%,and it had good purification effect.This study found that the demonstration area of wetland could achieve good effect on reused water treatment.And it also provided a method for water reuse and ecological restoration along the water diversion line.
