8种乡土湿地植物对珠三角地区城市生活污水的净化效果
Purification Effect of 8 Native Wetland Plants on Urban Domestic Sewage in the Pearl River Delta Region
摘要
Abstract
To investigate the purification effect of native wetland plants on local urban sewage and clarify the possibility of using native plants instead of exotic introduced plants for water body restoration,eight native plants in Guangdong Province were selected:Ranunculus sceleratus,Commelina diffusa,Nephrolepis cordifolia,Monochoria vaginalis,Alocasia macrorrhiza,Kyllinga brevifolia,Ludwigia adscendens,and Acorus tatarinowii.Through a simulated hydroponic experiment,the removal effects of these plants on chemical oxygen demand(COD),ammonia nitrogen(NH4+-N),and total phosphorus(TP),as well as their sewage adaptation capabilities,were explored.The results showed that wetland plants had a significant ability to remove nitrogen and phosphorus from water,and their removal effects varied with plant species and treatment time.Ranunculus sceleratus,Ludwigia adscendens,and Acorus tatarinowii could effectively remove phosphorus,achieving optimal removal rates of 92.40%,95.33%,and 96.20%in high-concentration sewage,respectively.All eight tested plants had good ammonia nitrogen removal effects,and the treatment time should be selected based on plant species and sewage concentration to achieve better removal rates.Therefore,all eight native wetland plants could be used to restore low-concentration domestic sewage,and when the sewage concentration is high,Ranunculus sceleratus,Ludwigia adscendens,and Acorus tatarinowii are recommended as restoration materials.These would provide a reference for the selection of plant materials for domestic sewage restoration in the Pearl River Delta region.关键词
