摘要
文章介绍了都市农业生态系统中的污水处理工艺和资源化利用方案,并对回用过程中的水质状况进行了连续监测与分析,结果表明,主要污染物CODCr、BOD5、浊度、TN的去除率均达到90%以上。再生水完全可以满足系统内农业灌溉的要求,每年可减少50%的地下水开采量,且提供了良好的景观资源。蟹岛生态度假村以生活污水处理为中心的水资源循环利用方式,为污水资源化利用工程作了有益的尝试并取得了良好的效果。
The paper introduced the comprehensive wastewater treatment technology and the reclaimed water utilization in an urban eco-agricultural system,Xiedao.The test results indicated that the removal of COD(Cr),BOD5,turbidity and TN were all over 90%.The reclaimed water quality was very stable and met the state requirements of irrigation and scenic water.Using reclaimed water for farm irrigation and aquatic farming,the holiday village system can reduce groundwater exploitation by 50% annually.What's more,a beautiful landscape was made and could also absorb more tourists.The mode of wastewater recycling utilization centered by sewage treatment in Xiedao has achieved benefits,which is favorable to reusing wastewater in practice engineering.
