Description
Technical field
The invention belongs to the harmless processing of municipal sludge and utilization of resources technology, particularly a kind of sludge drying system.
Background technology
Municipal sludge is meant the solid waste that produces in city domestic sewage, the Industrial Wastewater Treatment process, is the regular product of municipal sewage plant.This sludge moisture content is high, perishable, the intensive stink is arranged, and contain toxic substances such as dioxin, bacterium, parasitic ovum and heavy metal.Therefore, need carry out harmless treatment and utilization again to mud, the mummification of mud then is the steps necessary of sludge treatment.The method of mummification at present mainly contains: traditional heat energy sludge drying and sun power sludge drying.
Tradition heat energy sludge drying is meant and utilizes mud heat drying integrated equipment that mud is realized drying and other treatment.According to the way of contact of thermal medium and mud, mummification equipment can be divided into direct mummification, indirectly drying and direct-technology types such as indirect combined formula mummification again.Wherein direct heating sludge drying factory is the most representative be Europe maximum sludge drying factory---(but evaporated water is 7 * 5000kg/h) to the B ransands of Britain; Indirect heating mummification factory is the most representative to be that (but evaporated water is 4 * 5000kg/h) in Hispanic Barcelona.American-European common drying process is main with rotary drum mummification, fluidized-bed mummification, disc type mummification generally.
