中文摘要：

针对污泥的同化填埋或建材化利用等后续处置方式，采用芬顿试剂及骨架构建体改善污泥脱水性能。骨架构建体分别由水泥、石灰、粉煤灰、菱镁矿、磷石膏两两复配而成。以调理污泥比阻、毛细吸水时间、沉降性能以及脱水泥饼含水率、脱水率为评价指标来考察芬顿试剂与骨架构建体组合而成的复合调理剂对污泥脱水性能的影响。结果表明，骨架构建体能强化芬顿试剂对污泥脱水性能的改善效果，实现污泥的深度脱水。复合调理后，污泥比阻最低可降至0．355×10^12m／kg，降低率达93．14％；毛细吸水时间降至15．3s，降低率达31．08%；分别采用离心和板框脱水方式，泥饼含水率可降至66．62％和39．3％，此时，脱水率分别达81．36％和93．95％。

英文摘要：

In regards of final disposal approaches of landfill or reutilization as building materials, Fenton＇s reagent and skeleton builders were used to improve sludge dewatering ability. Skeleton builders were groups in which two different kinds of compounds were chosen from cement, lime, fly ash, magnesite and phosphogypsum. SRF, CST, settlement performance, water content of dewatering sludge cake and dewatering efficiency were used as indexes to evaluate sludge dewatering perfor- mance of the composite conditioner, Fenton＇s reagent combined with skeleton builders （F-S composite conditioner）. Results showed skeleton builders could enhance the effects of Fenton＇s reagents to improve sludge dewatering ability and obtain deep dewatering. After combined conditioning, SRF falls to 0.355×10^12m/kg, reduction efficiency is around 93.14%, CST is 15.3 s, reduction efficiency is up to 31.08%, water content of the dewatered sludge cake is 66.62% for centrifugal dcwatering and 39.3% for frame filter press dewatering, and dewatering efficiency is 81.36% and 93.95% respectively.
