Description
Technical field
The present invention relates to a kind of method to wet sludge disposal and product, particularly relate to a kind of method, moisture eliminator and the quality coal in cement kiln systems that make wet sludge anhydration.
Background technology
Mud is the product generated after Sewage Plant process waste water.Mud can be divided into dewatered sludge (mud that namely water content is few, in lump shape) and wet mud (mud that namely water content is more, in magma shape or muddy).Usually the wet mud of every ten thousand stere waste water generation can reach 5-10 ton.The annual generation mud that wets about closely reaches about 4,000 ten thousand tons.Have a strong impact on urban development.Conventional sludge disposal mainly contains the means such as sanitary landfill, compost, burning.But all exist and take up an area the problems such as large, mass-producing is low, secondary pollution is serious, operation investment is high.Cement industry has the function disposing waste, obtains international endorsement, because the main chemical compositions of mud comprises SiO
