Description
Technical Field
The embodiment of the invention relates to the technical field of solid waste treatment, in particular to a method for treating kitchen waste, kitchen waste and domestic sludge by using a cement kiln in a drying way.
Background
The kitchen waste mainly refers to food processing residue and food residue generated in restaurant, dining hall, school and other catering industries, and the kitchen waste is wet waste in urban waste classification and accounts for 50% -60% of the urban waste. The kitchen waste and kitchen waste are very complex in components, and mainly comprise a mixture of oil, water, fruit peels, vegetables, rice flour, fish, meat, bones, waste tableware, plastics, paper towels and other substances. With the increasing emphasis of the nation on garbage treatment and the proposition of "non-waste cities", the classification work of municipal garbage is continuously promoted, and the regulation on garbage treatment and disposal is increasingly strict, so that a more effective, safe and reliable process technology capable of centralized treatment is required to treat the wastes, thereby ensuring the urban environment and food safety.
The domestic sludge is sediment, particles and floating materials generated when the sewage treatment process utilizes a physical method, a chemical method, a biological method and the like to treat the wastewater. Sludge treatment is a process of carrying out reduction, stabilization and harmless treatment on sludge. If the sludge can not be reasonably treated, secondary pollution can be caused.
The kitchen waste and the kitchen waste have the characteristics of high water content, high organic matter content, easy deterioration to cause pollution, obvious adjacent avoidance effect and the like as well as domestic sludge, and are suitable for replacing fuel after being dried. At present, the main large-scale disposal mode of kitchen waste is a fermentation method, the technology is relatively mature, but the operation cost is high in practical application, the adjacent avoidance effect is serious, at present, large kitchen waste and kitchen waste disposal gaps are still difficult to fill in most of various-scale cities, the cost for cooperatively disposing the kitchen waste by using a cement kiln is low, the kitchen waste can be disposed in original production enterprises, the process is simple, and certain advantages are achieved in the aspect of operation stability.
The cement kiln cooperative treatment is a good sludge treatment way for domestic sludge, and the alternative fuel after the domestic sludge is dried is successfully applied to cement enterprises. Under the dual-reduction strategy, as the indexes of the fire coal are tightened, the domestic sludge contains rich organic matters, and the preparation of the alternative fuel after drying is a necessary trend of cement kiln cooperative treatment. The method for treating the municipal sludge by using the rotary cement kiln not only has the volume reduction and quantitative reduction characteristics of an incineration method. And the burned residues are calcined and cured to become a part of cement clinker, so that secondary treatment is not needed, the process is safe and reliable, and the cement clinker production method is a beautiful cement production way.
Kitchen garbage and kitchen garbage can't directly get into sludge drying device and carry out the mummification, mainly has following three aspect reasons: firstly, kitchen waste can not be thoroughly separated, and is often mixed into two or more other wastes, and the normal operation of the kitchen waste is affected when the kitchen waste directly enters the drying equipment; secondly, the kitchen waste and the kitchen waste generate leachate with high organic content and high water content, so that excessive kitchen waste leachate is easy to flow out in the conveying and feeding processes, and is difficult to treat in a sewage treatment facility of a cement enterprise even after being collected; thirdly, the kitchen waste and the kitchen waste contain certain grease, so that the kitchen waste and the kitchen waste have higher economic value and are worth recovering. The above problems also need to be solved.
China is a big agricultural country, the straw resources are very rich, and the annual output is huge. According to estimation, the yield of various crop straws reaches 7 hundred million tons every year in China. At present, the technologies for processing and recycling crop straws mainly comprise fertilizer utilization of straw returning, utilization of silage, utilization of chemical raw materials, incineration, power generation, anaerobic fermentation and the like. The production of alternative fuel by straw is an important way for the resource utilization of straw, but the crushed straw is burnt too fast to directly substitute the fuel.
CN206262969U introduces a kitchen waste, sludge and green waste cooperative disposal system, and CN109942161A introduces a sludge, excrement and kitchen waste cooperative anaerobic digestion process, and the prior art adopts a method for comprehensively treating various raw materials, but mainly adopts a fermentation process, and the difficulty and the energy utilization efficiency of waste water treatment are different from the cement kiln cooperative disposal.
