Effects of Fe (ⅲ) on floc surface properties and bioflocculation of activated sludge

胞外聚合物、Ca~（2+）及pH值对生物絮凝作用的影响

Effects of extracelluar polymeric substances , Ca ~ ( 2 + ) and pH on bioflocculation

应用阳离子交换树脂从活性污泥中提取了胞外聚合物（EPS），考察了EPS、Ca2+及pH值对生物絮凝作用的影响。

Applying the cation exchange resin extracelluar polymeric substances ( EPS ) were extracted from activated sludge , and the effects of EPS , Ca2 + and pH on bioflocculation were investigated .

投加絮凝剂后，通过生物絮凝作用，污泥粒径增大，形成较大的絮体。污泥的SVI也有一定程度的降低，污泥的沉降性能得到了改善。

After adding flocculants , the biological flocculation could increase the size of sludge and then generate a bigger sludge floe , the SVI of sludge also decreased , and the sedimentation ability improved .

并且有机物种类对污泥的吸附性能有显著影响，研究表明吸附机理主要是生物絮凝作用。

The kind of organic affected adsorption capability of sludge remarkably . The study showed that mechanism of adsorption was biological flocculation function .
