【摘要】 磷既是一种不可再生的资源,也是造成水体富营养化的重要因素。近年来,随着磷资源的匮乏,从污水处理厂回收磷在世界各国逐渐兴起,而我国在这方面的研究还基本处于起始阶段。为此,在某污水处理厂进行了以鸟粪石形式回收磷的小试实验,考察了磷回收的一些控制参数,并将以此作为基础,继续深入研究。更多还原

【Abstract】 Phosphorus is a non-renewable and limited resource,and is also the key element that causes eutrophication of waters.In recent years, with the decrease of world’s phosphorus resource,many phosphate recovery processes have appeared in wastewater treatment plants.While in China,the stuy of this area is still in the beginning.So,the authors have done some work in order to analyze the parameters of the phosphate recovery.And based on the parameters,further research will be done.更多还原
