摘　　要：为实现城市污水处理厂污泥脱水性能提升,研究利用过二硫酸盐强氧化性能和聚合硫酸铁的高效絮凝功能,协同调理城市污水处理厂活性污泥,采用响应曲面试验技术,探索最优化污泥调理技术参数。结果表明,污泥脱水性能显著提升,提高了污泥束缚水的释放。To improve the sludge dewatering performance of urban sewage treatment plant,a new sludge conditioning strategy is developed using peroxydisulfate(PDS)as an oxidant and polyferric sulfate(PFS)as a coagulation-flocculation reagent.Response surface test is used to explore the optimization of sludge conditioning technical parameters.The results show that the synergistic affection of PFS and PDS could generate SO4-o and oOH,which enhances the release of bound water from sludge.
