With the continuous development of China's economy and the improvement of residents' living standards, the amount of urban household waste generated is increasing, and waste disposal has become a major issue related to people's livelihood. According to incomplete statistics, in 2014, the daily garbage production in Beijing and Shanghai exceeded 12000 tons, and the national daily garbage production reached 356000 tons. The harmless treatment of urban solid waste is becoming increasingly urgent. At present, more than 70% of the garbage treatment in many developed coastal areas, including Guangdong, has not reached the harmless treatment standard. Traditional landfill, composting, and open burning treatments have many shortcomings. How to make garbage treatment harmless, resourceful, and reduced has become a key issue that relevant government functional departments need to consider and solve.
At present, many cities still use traditional landfill as their domestic waste treatment method, and a few cities adopt immature biochemical composting treatment method. There are many shortcomings in the treatment methods of municipal solid waste in these cities, and they are also facing many difficulties. The limitation of landfill site selection is that even with a suitable site, it is easy to cause secondary pollution of groundwater resources and environmental pollution around the site. The landfill of garbage produces biogas and causes serious pollution to the atmosphere.
Refuse incineratorStoves have contributed to beautifying the environment. The use of pyrolysis gasification furnace for incineration of household waste is a new type of combustion technology, which has the advantages of sufficient combustion, high thermal efficiency, reduced slag burning amount, and easy control of flue gas pollution indicators. However, the single furnace processing capacity is limited by the furnace diameter and difficult to improve.
