鸟粪石

Taking sludge dewatering filtrate as research object,the impacts of stoichiometrical initial Mg2+,PO43- and NH+4 concentrations,initial NH4+ concentration and initial Ca2+ concentration on the recovery effect of struvite were investigated.

以污泥脱水滤液为研究对象，考察了按照等化学计量比改变Mg2+、PO43-和NH4+的初始浓度、单独改变NH4+初始浓度和单独改变Ca2+初始浓度对鸟粪石回收效果的影响。

This paper discussed the formation mechanism and influencing factors of struvite .

论述了鸟粪石的形成机理、形成的影响因素。
