Because of the complexity of municipal waste composition, economic development, structure, natural conditions and traditional habits and other factors, so the level of foreign municipal solid waste treatment is generally in line with the national conditions, often a country in the region has also adopted different methods, it is difficult to have a unified model, but ultimately harmless, resources, and reduce the treatment goals. From the application of technology, landfills, incineration, composting, comprehensive utilization, high degree of mechanization, and the formation of systems and equipment in the external key. From the treatment of various foreign situations, the following trends: (1) industrial countries, energy, land resources are increasingly tight, the proportion of incineration is gradually increasing, (2) landfills as a means of final disposal of waste has always accounted for a large proportion; (3) most of the developing countries based on agricultural composting; (4) new technologies such as pyrolysis, reclamation, heap mountain landscape technology is constantly progressing.
Municipal waste incineration technology is widely used in large-scale waste incineration systems around the world equipped with heat recovery and utilization of equipment to meet the requirements of energy recovery gradually increased to the mainstream of incineration. Foreign industrialized countries, especially Japan and Western Europe, generally committed to promoting the application of waste incineration technology. Widespread use of foreign incineration technology, in addition to economic development, investment and strong, high calorific value of waste, incineration process is mainly due to the benefits of mature and advanced equipment. Many well-known companies in the world have invested efforts to develop incineration technology and equipment, the main equipment and support slave equipment models. Foreign industrialized countries are committed to improving a variety of new incinerator incinerator and development, toward high efficiency, energy saving, low cost, low pollution direction, the degree of automation is getting higher and higher.
In China's urban waste treatment started late, by the end of 1992, the national garbage, feces clear amount reached 112.64 million tons of garbage, feces harmless treatment plant with a total processing capacity of only 37171501 tons per day. In recent years, according to the actual situation of each place, continue from the strategy and planning, a useful exploration of urban waste treatment technology. Hangzhou, Changzhou, Tianjin, Mianyang, Beijing, Wuhan and other cities of urban waste treatment technology, drawing on foreign experience, their own design with Chinese characteristics of the garbage mechanized composting production line on the basis of Shenzhen City, Leshan City, the success of the construction of waste incineration power plant, but also to provide the city to apply the experience of incineration technology, Sinkiang, Anshan City, the unified management of hospital wastes, centralized incineration, but also walked out of a new road! The special garbage treatment.
