摘要
LID/GSI技术是应对城市雨洪问题的有效理念和技术体系,多用来研究探讨雨水滞留系统表层植物及下垫面滤料的更新。但同时,滤料的层叠造成滞留池内氧分供应缺失,长期滞留的污染物滤料堵塞、水力水头损失等现象也颇为常见。CRCT(constructed root channel technology)植物根孔技术近年来在农业及水质处理方面的大量试验证明,植物根孔在土壤水分流动及物质截留等方面具有特殊性能,对由填埋植物秸秆作为滞留池填料/介质,结合生物滞留池的特点,对常年雨水的调蓄及水质处理方面有较好的作用。
The LID/GSI technology is one of the best concept and technological system to cope with the problems of urban rainwater. Most of the studies have probed the surface plants and filter of rainwater detention system. But at the same time, oxygen supply stranded is poor because of filter material, long-term retention of pollutants lead to filter material blocked up. CRCT （constructed root channel technology） has been got a lot of tests, based on plant roots in the soil pore and other aspects of the characteristics of the material, in terms of agriculture and water treatment verification in recent years. For the landfill plant straw as detention ponds filler/media, having a good effect on the flood storage and water treatment combined with the characteristics of biological detention pond.
