随着建筑小区对环境的生态功能、水环境质量、污水处理成本以及水资源综合利用的需求逐步提高,势必需要引入和发展一种成本低、管理方便、运行稳定可靠的新型生态治污技术.深圳市环境科学研究院研发的高效垂直流人工湿地技术由于具有景现效果好,污染物去除效率高等特点已被广泛地运用于小区污水处理回用和湖水循环净化.大量实践结果表明:系统对SS,COD,BOD5,NH4-N,TP具有较高的去除效果,在水力负荷0.33 ～0.50 m/d条件下,去除率大部分达到80％以上;出水水质均达到城市污水再生循环利用水质标准.%With the increase of requirement for ecological function of environment, for quality of water environment, for sewage treatment cost and for comprehensive utilization of water resources, it was bound to introduce a new type of ecological technology for pollution treatment which was low in cost, convenient in management and stable in operation. Constructed wetland of high-efficient vertical flow developed by Shenzhen Academy of Environment and Science was characterized by good landscape effect and high efficiency of pollutants removal, and it had been widely applied in sewage treatment and recycling and in lake water circulation purification. A lot of practical results showed that this technology can achieve high removal efficiency of SS, COD, BOD5, NH4-N and TP and the removal rate had arrived at more than 80% when hydraulic loading was 0. 33 -0.50 m/d. Effluent quality had met the water quality standard for recycling of urban sewage.
