摘　　要：在无锡蠡溪公园西苑水体中采用了水动力循环复氧控藻(HAAC)技术,研究了该技术对城市景观水体富营养化的处理效果。结果显示:在实施水动力循环复氧控藻(HAAC)技术的8个月期间,CODMn、TN、NH4+-N和TP平均去除率分别达到28.0%、35.7%、49.7%和37.0%;藻类叶绿素a平均去除率达40.2%,藻类总丰度平均下降率达56.0%,藻类群落从单一结构转变为多种优势种共存的结构。水华现象得到了有效控制,水体生态环境明显转好,处理期结束时西苑水体已达到IV类水标准。研究表明,水动力循环复氧控藻技术作为一种新型的水生态修复技术在城市景观水体富营养化治理工程中起到了很好的效果,值得推广应用。To solve the eutrophication problem in urban landscape waters,the Hydro-circulatory Aeration and Algae Control(HAAC) technology was applied in Wuxi Lixi Park.By monitoring the water quality indexes for more than 8 months,the performance of the HAAC technology in treating the urban landscape water body was investigated.The results that CODMn,TN,NH4+-N,and TP decreased by 28%,35.7%,49.7%,and 37% respectively.The average removal rate of Chlorophyll a was up to 40.2%.Total algae abundance declined by 56% and algal community changed from a single-specie dominant structure to a multiple-species dominant structure.The water algae blooms have been well controlled,and the ecological environment gets better apparently.The water quality meets surface water class IV standards.In conclusion,HAAC technology has shown great applicability in eutrophication treatment of an urban landscape water body as an new aquatic rehabitation technology.
