工业硫酸亚铁对A~2/O氧化沟除磷效果的影响

以汕头龙珠水质净化厂部分运行工段作为实验对象 ,将工业硫酸亚铁投加于A2 O氧化沟的好氧段 ,测定出水中总磷的变化 ,发现硫酸亚铁的投加能够迅速、直接地提高氧化沟的除磷效果 ;同时辅以相差显微镜对A2 O氧化沟的厌氧段、缺氧段、好氧段的活性污泥进行观察并摄影 ,发现工业硫酸亚铁的投加对活性污泥的性质并无改观作用

Research on the Effect of Phosphorus Removal of A2/O Oxidation Ditch Through Adding Industrial Green Vitriol

Regarding some operation sections of Shantou Longzhu Sewage Treatment Plant as the research projects, we added the industrial green vitriol in the oxic phase,and then measured the change of total phosphorus of output water,we found that adding the industrial green vitriol could improve the effect of phosphorus removal of A 2/O oxidation ditch rapidly and directly. At the same time,we photographed and observed the active mud in anaerobic,anoxic and oxic phases of oxidation ditch through the electron microscope with photography devices,we found that adding the industrial green vitriol could not change the function of the active mud.
