摘要： 为研究水生动植物组合对富营养化园林景观水体的净化效应,将秋枫(Bischofia javanica)、水蓑衣(Hygrophila salicifolia)、苦草(Vallisneria natans)、叉尾斗鱼(Macropodus opercularis)、中华圆田螺(Cipangopaludina cahayensis)和生物质焦材料组合成生物处理系统,以富营养化园林水体为治理对象,研究了生态净水系统中水生动植物的生长状况,对水体中TN,TP,COD,NH+4-N,NO-2-N等污染物的净化效果以及系统在消除水中孑孓的作用。结果表明:净水系统中无蚊子幼虫出现且水生动植物生长状况良好,对水体中TN,TP,COD,NH+4-N,NO-2-N等有较好的去除效果,其去除率分别可达64.4%,49.5%,65.7%,73.8%,82.6%;TN,COD,DO等指标均符合地表水(GB 3838—2002)Ⅳ类水标准,而NH+4-N则符合Ⅱ类水要求。应用生态净水系统对于去除富营养化水体中主要污染物和蚊虫滋生起到了一定的作用,系统中各组成要素各司其职,技术友好,有助于实现可持续性水生态修复。

Abstract: An aquatics combination system composed of Bischofia javanica, Hygrophila salicifolia, Vallisneria natans, Macropodus opercularis, Cipangopaludina Cahayensi and biomass char was applied to the treatment of eutrophic garden scenic waters. The growth status of aquatics in this system and the aquatics’ effect of eliminating larvae and wiggler as well as the purification effect for TN, TP, COD, NH+4-N, and NO-2-N in the water body were examined. Results showed that no larvae or wiggler was found in the aquatics combination system which enjoyed a good growth status and a satisfactory effect of removing pollutants. The removal rate of TN, TP, COD, NH+4-N, and NO-2-N reached 64.4%, 49.5%, 65.7%, 73.8% and 82.6%, respectively. The content of TN, COD and DO met the standard of surface water quality IV-level specified in national standard GB 3838—2002, and NH+4-N measured up to level Ⅱ. In conclusion, each component in the aquatics combination system performs its duty, and the technology is pollution-free, hence is conducive to the sustainable water ecological restoration.

Key words: aquatics, biomass char, aquatics combination system, eutrophic scenic waters, purification effect
