| 摘 要： | 结合某海绵校园重力流生态滤池工程实例,针对重力流生态滤池处理工程中防堵塞管理和植物管理等问题进行概括性地分析探讨;研究发现,采用滤网过滤、厌氧沉淀、混凝沉淀等预处理工艺可有效截流雨水径流中的颗粒污染物;通过机械清除、介质固化、介质覆盖等局部更换介质的方法可较好地解决堵塞问题,实施停床休作与轮作、定期清洗清淤也有利于发挥重力流滤池的正常效能;同时,植物作为重力流生态滤池中净化功能和生态景观最重要的一部分,针对其具体的选用原则、种植方式及合理密度等方面进行研究,提出了进水单元种植驱蚊类植物、中段单元种植抗藻类植物、出水单元种植抗藻和杀菌类植物的配置方案,并给出了一些典型植物的种植密度和日常管理方式等;最终可达到降低生态滤池进水中的悬浮物和有机负荷、有效预防生态滤池堵塞、维持生态滤池系统稳定的效果.

| Abstract: | Based on a sponge campus gravity flow ecological filter project,the problems in the project,such as anti-blocking management and plant management and so on,were analyzed and discussed briefly.The results show that the pretreatment processes such as filter screen filtration,anaerobic precipitation,coagulation and sedimentation are effective in intercepting particulate pollutants in rainwater runoff.Medium local replacement methods,namely mechanical removal,medium solidification and medium covering can better solve blocking problem.The implementation of operating-break and opera-ting-in-shift,regular cleaning and desilting is also conducive to the normal performance of gravity flow filter.Since plants are the most important part of purification function and ecological landscape in gra-vity flow ecological filters,the plant specific selection principle,planting method and reasonable density are investigated.A planting scheme is proposed,in which mosquito repellent plants are planted in the intake unit,algae resistant plants in the middle unit,algae resistant and bactericidal plants in the outlet unit.Further,the planting density and daily management method etc are also put forward for some typical plants.Eventually,suspended substances and organic load in the water of ecological filter can be reduced to effectively prevent the ecological filter from blockage and maintain its stability. |
