多孔陶瓷滤球与沉水植物联合作用处理杭州西湖沉积物中的磷
Phosphorus removal with combined technology of porous ceramic filter material and submerged plants from sediment in West Lake, Hangzhou, China
摘要
Abstract
The effects of a combination of red mud-based porous ceramic filter material (PCFM) and submerged plants for the removal of all fractions of phosphorus from sediment were investigated.The effect of this combined technology involving adsorption and biological treatment was studied by testing for the presence of each form of P in the sediment.The results indicate that the removal of P from sediment by Vallisneria natans gradually increased with increasing reaction time.The quantities of TP,OP,IP,Fe/Al-P,and Ca-P removed after 150 d were 51.60,16.32,34.74,46.37,and-14.99 mg· kg-1,respectively.The treatment effect of a combination of Vallisneria natans and 5 cm PCFM showed the best performance,and the quantity of TP,OP,IP,Fe/Al-P,and Ca-P removed after 150 d reached 652.61,249.12,396.40,314.38,and 72.11 mg· kg-1,respectively.This study suggests that the combination of PCFM and macrophytes could achieve synergetic removal of P from sedi ment because the removal rates achieved through the combination were higher than the sum of those obtained using PCFM and macrophytes separately.The combined technology of PCFM and submerged plants can be further applied to control P in sediments in eutrophic lakes.关键词
