城市富营养化水体底泥净化磷效果
Effect of phosphorus purification by sediments in a eutrophic city water body
摘要
Abstract
The purification of phosphorus（P） by the sediments under sediment disturbance conditions was investigated,using the sediments and overlying water in a eutrophic city water body.The results showed that the total input P with the amount of 19.92 mg and 13.61 mg disappeared from the overlying water to the sediments（200 g） under disturbance conditions and static conditions,respectively.Under anaerobic conditions,the percentage of P release from the former to the total adsorbed P was 43%.However,the value of the latter increased to 63.4%.It is indicated that sediment disturbance enhanced not only P adsorption but also P immobilization in the sediments.The proportion of the increase of refractory P forms（HCl-P,occluded Fe/Al-P） to the total adsorbed P under sediment disturbance and static conditions was 36% and 21%,respectively.关键词
