Description
Technical field
The present invention relates to a kind of mud pre-treatment and cement kiln comprehensive utilization method and system thereof.
Background technology
Trade effluent (waste water that comprises discharging such as printing and dyeing, papermaking, leather, chemical industry and various mechanical industries) and sewage after treatment; When sewage is purified; Account for the mud that gets into sewage work's sewage total amount about 1% with producing volume; This type mud also contains a large amount of pathogenic agent and various heavy element except containing spissated inorganic and organic contamination beyond the region of objective existence.Therefore; The mud that is produced in the sewage treatment process is carried out safety and disposal economically, is the important component part of Sewage treatment systems, if mud can not get dealing carefully with; Not only directly have influence on the normal operation of Sewage treatment systems, and can bring secondary pollution to environment.
At present, China throws aside or the method for landfill is handled to most employing of sludge of sewage treatment plants, have only indivisible carry out being used for making after the mummification mix fertile.Because the landfill yard standard implementation of China is later, old landfill yard is admitted mud, possibly cause a large amount of mud pollutents to get into deep layer with percolate from the face of land, even threatens underground water and rivers,lakes and seas.There is few part cement mill directly to spray into calcined by rotary kiln to mud; This method has realized safe, harmless, the disposal of resources of mud; But because 70-85% moisture need be accomplished evaporation in the mud in rotary kiln; Cost of disposal is high, processing power is little, and causes thermal technology of cement rotary kiln system and quality product fluctuation easily.The sludge fuel elelctrochemical power generation also has application, but this method finally also can produce ashes, needs further to dispose; And still need consume the moisture content in the great amount of heat energy dewatered sludge in the sludge fuel process, truly not accomplish " resource utilization, energy-conservationization " utilization.
Literature search through to prior art is found; The Chinese patent of application number 200910100117.6 disclose a kind of in manufacture of cement the method for cooperatively processing sludge; This method is to utilize existing new type nonaqueous cement clinker production line to produce cement clinker and cooperatively processing sludge; The paper mill sludge of water ratio >=70% is directly added Vertical Mill, mix with cement raw material, levigate, make cement slurry; But this invention is primarily aimed at paper mill sludge;
Application number is to disclose cement clinker and working method thereof that dewatered sludge ingredient makes in 200710045299 the Chinese patent; But this method utilizes kiln tail high-temp waste gas as the oven dry thermal source; Cause the NH3 in the mud in the drying course; The volatilization of materials such as H2S very easily causes the discharging in the cement production process to exceed standard.
A kind of method of utilizing cement mill smoke residual heat to dry sludge and firing sludge cement is disclosed in the Chinese patent of application number 200910102069; Mud and clay matter and the calcareous raw material that will pass through after the mummification are mixed into raw material, through milling, calcine, processing cement after the cooling, grinding.The problem of this method is: mud is gone into kiln as raw material, and the volatile matter in the mud just decomposes in preheating in rotary kiln device low-temperature zone, and then discharges with waste gas, is difficult to reach safe and harmlessization treatment requirement.
