不同覆盖方式对底泥内源营养盐释放的控制效果
Control effect of different covering patterns on indigenous nutrient release from sediment
摘要
Abstract
A laboratory simulation experiment was conducted to study the release of sediment phosphorous and nitrogen under the effects of coating the sediment with plastic, clinoptilolite, calcite, quartz sand, and calcium nitrate, aimed to provide scientific basis and technical support to control the sediment nutrient release under the background of water environment pollution by different concentrations of nitrogen and phosphorus. The control efficacy of test coating materials for sediment total phosphorous release was in the order of plastic > calcium nitrate > clinoptilolite > calcite > quartz sand, and that for sediment total nitrogen release was in the order of clinoptilolite > plastic > calcite > quartz sand > calcium nitrate. As for the release of sediment N03--N, the control efficacy of test coating materials was calcium nitrate > quartz sand > clinoptilolite > calcite > plastic coating; whereas for the release of sediment NH4+-N, the sequence was calcium nitrate > plastic coating > clinoptilolite > calcite > quartz sand. Water temperature had definite relativity to the sediment nutrient release. With the increase of water temperature, the concentrations of water total phosphorous and nitrogen and N03--N increased, while the concentration of water NH4+-N presented a declining trend.关键词
