在相同PAFC投加量下，化学生物絮凝工艺对各项污染物的去除效果均显著优于传统的化学强化一级工艺，剩余污泥产量比后者减少10～15%。

Under the same PAFC dosage, the chemical-biological flocculation was superior to the chemically enhanced treatment process and its surplus sludge was less than the latter by 10-15%. ?

比较实验表明，VCG比未改性的壳聚糖的絮凝效果更好，COD去除率更高，且投加量更低。

The compared test showed that VCG's flocculating was better than the unchanged chitosan, and COD's removal rate was higher with lower dosing quantity.

对生物活性污泥的絮凝脱水性能的研究结果表明，LSDC在提高沉降速度、降低污泥含水率和污泥过滤比阻方面有明显效果，优于对比样CPAM。

It could be concluded that LSDC can obviously speed up the sedimentation rate of sludge, decrease moisture content and specific filtration resistance of sludge, which was superior to CPAM.
