Abstract

The current situation and development trend of sludge treatment and disposal at home and abroad are analyzed. The main technical scheme of sludge blending combustion is studied. The technical route of "sludge storage system + low temperature carbonization system + plate-frame pressure filtration system + boiler incineration" is put forward. Combined with the actual situation of coal-fired units

several systems such as wet sludge transportation and storage system

sludge carbonization system

dry sludge transportation and storage system as well as deodorization system were designed. The sludge coupled power generation technology can effectively reduce and stabilize the sludge and make it harmlessness and resourceful

which has significant social

environmental and economic benefits.
