底栖藻类-苦草对猪粪废水中磷的滞留作用研究
Study on Phosphorus Retention Using Benthic Algae-Vallisneria natans Grown with Piggery Wastewater
摘要
Abstract
To study the phosphorus retention and its form retained by benthic algae and submerged vegetation ( Vallisneria natans) in treating piggery wastewater , and evaluate the potential utility of this system in controlling eutrophication and agricultural effluent treatment , the phosphorus content and its form in benthic algae and Vallisneria natans were investigated using a sequential extraction SMT protocol .The systems were exposed to different loading levels of swine manure over a 30 d indoor incubation period .The results indicated that both benthic algae and Vallisneria natans illustrated significant phosphorus retention effect .The phosphorus retention was enhanced in the mixture of periphyton and Vallisneria natans. The phosphorus retention capacity was higher with higher swine manure loading .Besides , inorganic phosphorus constituted most of the total phosphorus in both benthic algae and Vallisneria natans, accounting for 43%~89% and 63%~94%respectively.And among these inorganic phosphorus , Fe-bound phosphorus accounted for 34%~64% and 20%~91%, followed by Ca-bound phosphorus , accounting for 17%~58%and 7%~75%, respectively .关键词
