摘要
生物滞留池是一种采用分散方法,从源头削减雨水和控制污染物迁移的高效LID措施。从水文效应、水质处理及模型建立三方面回顾了国外生物滞留池的研究现状,对生物滞留池用于国内城市雨水径流控制展望如下:在满足水量负荷下对溶解性N和颗粒悬浮物去除的研究;生物滞留池长期运行稳定性研究,包括填料的二次污染和自然再生等;生物滞留池水力模型和水质模型的研究必须与理论研究相结合,以减少试验周期和优化试验参数。
Bioretention is a measure of LID with high efficiency to reduce rainwater from the source with decentralized approach and control the migration of pollutants. The status of foreign bioretention cell for urban stormwater runoff control in the aspect of hydrological effects,water treatment and models were reviewed. The prospects of domestic stormwater runoff control were as follows: Solving the dissolved N and granular suspended matter to meet the standard of water quality under proper hydraulic loading. The stability of bioretention under long running,including fillers such as secondary pollution and natural regeneration,should also be taken into consideration. Hydraulic and water quality models must be combined with the theoretical studies for reducing test cycles and optimizing the parameters of experiment.
