摘要
针对目前国内缺少大型景观水体水质维护的长效机制,综合分析了国内大型景观水体水质维护系统的结构设计,肯定了现有维护系统在设计和运用中的技术示范价值。在实际运营过程中,以上海辰山植物园景观水体水质维护系统为例,研究发现城市大型景观水体存在循环水水质变差、水力停留时间较短、人工湿地功能较弱等问题,剖析了有关的生态学问题,从"减少污染物质的输入"和"增加污染物质的输出"两方面提出了管理优化对策。
Due to the lack of long-term mechanism of water quality maintenance in large-scale recreational water, the design structures of domestic recreational water quality maintenance system have been analyzed. It was shown that there were technological demonstration values from the design and application levels. However, in the coarse of actual operation, there were many problems such as poor quality of water circulation, short hydraulic retention time, weaken function of constructed wetland in the water quality maintenance systems of Shanghai Chenshan Botanical Garden. Hence, the authors put forward some optimization strategies about management from the two aspects of reduction pollutants input and raise pollutants removal.
