摘　　要：为了解决传统透水堰对污染物迁徙转化效果有限的问题,采用陶粒、天然沸石、红砖屑、轮胎颗粒、火山岩构建生态净水堰,通过对生态净水堰内填料的特性分析,对填料区填料的质量比和铺设型式、反应器构型的比选,研究不同组合系统下生态净水堰的净化效果。结果表明:天然沸石对氨氮的吸附能力最好;陶粒对磷的吸附能力最优。6种不同的填料质量比为陶粒:火山岩:天然沸石:轮胎颗粒(1:1:2:1)的填料对氨氮和磷的吸附能力最好。在不同的进水浓度和水力停留时间下,通过对动态试验数据进行多元方差分析,在以截留、吸附为主的污染物去除过程中,推流式反应器结构和垂直分层铺设的布局系统效果最优。In order to solve the problem that the traditional permeable sputum has limited effect on the migration and migration of pollutants,the ceramsite,natural zeolite,red brick shards,tire granules and volcanic rocks are used to construct the ecological clean water raft,and the characteristics of the filler in the ecological clean water raft are analyzed.The comparison between the mass ratio of the zone filler and the laying form and the configuration of the reactor was carried out to study the purification effect of the ecological clean water raft under different combined systems.The results show that the natural zeolite has the best adsorption capacity for ammonia nitrogen;the ceramsite has the best adsorption capacity for phosphorus.Among the 6 different filler mass ratios selected,the mass ratio is ceramsite:volcanic rock:natural zeolite:tire particles(1:1:2:1)have the best adsorption capacity for ammonia nitrogen and phosphorus.Under different influent concentrations and hydraulic retention time,through the multivariate analysis of variance of dynamic test data,the structure of the push-flow reactor and the vertical layering were carried out during the removal of nutrient-based pollutants based on interception and adsorption.The combined type works best.
