【摘要】 采用有孔洞的泡沫板为栽培定植板,研究水稻对3种不同浓度污水中N、P的去除作用。结果表明,水稻对低、中、高浓度污水的TN去除率分别为54.5%、71.0%、66.3%,对低、中、高浓度污水的NH4+-N去除率分别为67.2%、75.6%、72.7%,对低、中、高浓度污水的TP去除率分别为69.4%、72.3%、55.1%。水稻对中浓度污水中TN、NH4+-N和TP的去除率最高,均超过了70%。水稻可用于受损水体的生物/生态修复。更多还原

【Abstract】 Using foam board with poles as planting plate,the effects of rice on floating beds on nitrogen and phosphorus removal were studied in sewages of three different concentrations.The results showed that rice’s removal rates of TN in low,middle,high concentration sewages were 54.5%,71.0%,66.3%,respectively.The removal rates of NH4+-N in low,middle,high concentration sewages were 67.2%,75.6%,72.7%,respectively.The removal rates of TP in low,middle,high concentration sewages were 69.4%,72.3%,55.1%.Rice showed the best removal rate of TN,NH4+-N,and TP for middle concentration sewage,which were higher than 70%.It indicated taht rice could be used for biological/ecological rehabilitation of damaged water bodies.更多还原
