摘要

城市污水处理过程中产生了大量剩余污泥，这些污泥具有含水率高、灰分含量高和热值低等特征，严重制约其焚烧减量与能量回收效果。污泥深度脱水常需引入化学调理剂与生物质骨架构建剂，但上述试剂对脱水污泥后续燃烧行为的影响尚缺乏系统认识。以FeCl

、CaO为典型化学调理剂，以稻秆、玉米秸秆和竹子为生物质骨架构建剂，调理后获得脱水污泥，并利用热重分析研究了脱水污泥燃烧特性。结果表明，FeCl

调理后，污泥的着火温度和表观活化能降低，燃烧特性指数增大，脱水污泥的燃烧反应活性显著提升；而CaO调理后，污泥的着火温度和表观活化能上升，燃烧失重率和燃烧特性指数减小，不利于燃烧。生物质调理时，脱水污泥总失重率和最大失重速率显著增大，着火温度随生物质添加量增大而上升，表观活化能由原污泥的26.60 kJ/mol增大至29.87~41.16 kJ/mol，燃烧活性整体趋于“生物质化”。与添加生物质相比，FeCl

-生物质协同调理后，污泥在保持较大总失重率的同时，表观活化能减小，CaO-生物质协同调理则使污泥的表观活化能增大，表明FeCl

-生物质具有更显著的协同促进作用。

Abstract

In the process of municipal wastewater treatment

a large amount of residual sludge is generated

characterized by high moisture content

high ash content

and low calorific value

which severely restricts the efficiency of sludge incineration for volume reduction and energy recovery. Deep dewatering commonly requires the addition of chemical conditioners and biomass skeletal agents. However

their effects on the subsequent combustion behavior of dewatered sludge remain insufficiently understood. Taking FeCl

and CaO as typical chemical conditioning agents and rice straw

corn stalk and bamboo as biomass skeleton builders

the dewatered sludge was obtained after conditioning. The combustion characteristics of the dewatered sludge were investigated using thermogravimet

ric analysis. The results show that after conditioning with FeCl

the ignition temperature and apparent activation energy of the sludge decreases

while the combustion characteristic parameters increase

significantly enhancing the combustion reactivity of dewatered sludge. In contrast

after conditioning with CaO

the ignition temperature and apparent activation energy of the sludge increase

while the combustion weight loss rate and combustion characteristic parameters decreases

which is unfavorable for combustion. When conditioned with biomas

the total mass loss and maximum mass loss rate increase markedly. However

ignition temperature increases with increasing biomass addition amount

and apparent activation energy rises from 26.60 kJ/mol for raw sludge to 29.87~41.16 kJ/mol

indicating an overall shift of combustion behavior toward biomass-dominated characteristics. Compared to adding biomass alone

FeCl

-biomass synergistic conditioning maintains a high total mass loss while exhibiting a lower apparent activation energy

whereas CaO-biomass synergistic conditioning increases apparent activation energy. These results demonstrate that FeCl

-biomass coupling exhibits a more pronounced synergistic promotion effect on combustion reactivity.
