摘　　要：从碳化稻壳特点入手,结合低影响开发技术设施的共同点,探讨碳化稻壳在海绵城市建设中应用的可行性。基于山西长治神农湖水环境治理与生态修复项目设计思路,将碳化稻壳应用于雨水花园和植草沟作为面源污染控制技术之一,发现碳化稻壳不仅能提高雨水下渗速度、吸附径流污染,还可以涵养水分、为植物根系保温并提供生长所需养分,为实现面源污染控制、水生态修复、园林景观提升、废物利用等多重功能产生积极的作用。碳化稻壳将成为未来海绵城市建设中可选的价格低廉、处理效果良好的新材料。Based on the characteristics of carbonized rice husk and the common points of low impact development technologies,this paper discusses the feasibility of the application of carbonized rice husk in the construction of sponge city.Considering the designing idea of water environment control and ecological restoration project of Shennong Lake in Changzhi,Shanxi Province,carbonated rice husk could be applied to rain gardens and grass swales as one of the non-point source pollution control technologies.It is found that carbonated rice husk can not only improve the infiltration rate of rainwater and absorb runoff pollution,but also conserve water,keep plant roots warm and provide nutrients for plants growth.It also plays a positive role in non-point source pollution control,water ecological restoration,landscape improvement,and waste utilization.Carbonized rice husk could become a new material with lower price and better treatment in the construction of sponge city in the future.
