Research on the Treatment Technology of Drying-Incinerating Integrated Systems for Sewage Sludge

The output of sewage sludge increases day by day. It will not only waste the land resource but also pollute the environment if it does not be treated. The water form and treatment technology of sludge were analyzed, and drying and incinerating were deemed to the most complete and steady treatment technology. A treatment technology of drying - incinerating integrated systems for sewage sludge was proposed which the heat amount from sludge incineration provides the requirement of the incinerating system and the whole　drying - incinerating integrated system can be self-support basically. The processes and technologies of the systmes were analyzed, and the results showed that the advantages of the systems were the large decrement of sludge, high drying efficiency, low running cost and effective control of the exhaust emissions.
