The Measure of Waste Disposal

The Issue of Waste Disposal

Urban solid waste refers to people in daily life or for the city in recent years, China's urban waste production overall show an increase in the trend of environmental pollution caused by this situation has become more and more uncontrollable.

 Causes

The landfill method is currently the main disposal method for urban household waste, but there are still some drawbacks. Urban household waste usually requires a large landfill site.The establishment of landfill sites has led to increasingly tense human land relations, but at the same time, it is prone to secondary pollution problems. The leachate generated by landfill waste can cause pollution of water resources and soil. Due to the degradation of internal organic matter, the land used for landfilling garbage produces uneven settlement, which makes it unable to be used as building land for houses for a long time, and also wastes land resources as farmland. The generated exhaust gas can pollute air quality and produce a greenhouse effect. However, the fermentation of garbage to form methane gas has the possibility of causing fires and explosions, which is not conducive to the circular development of resources. Therefore, some developed countries have ordered the prohibition of landfill treatment of domestic garbage. Moreover, due to economic constraints, the treatment level and capacity of the city's waste treatment plants are limited, and they are facing the problem of establishing new landfill sites after the service period expires.

 Strategy

However, the landfill method should also be used as the main waste disppsal. And it mainly for these aspects:

 

Economy: Firstly, considering the development level and economic factors of the city. In recent years, the development of the city has been slow and the economic level is relatively low. The landfill method has the advantages of easy operation, large disposal capacity, low investment in infrastructure and funds, low operating costs, and a wide trial range, which is suitable for the actual situation of the city's development.

 

Social: Secondly, considering the social factors of the city. The landfill method can concentrate urban household waste in a single place for treatment, usually located in relatively remote suburbs. The city is relatively vast and sparsely populated, creating ideal spatial conditions for the establishment of landfill sites. The construction of landfill sites in suburban areas far from the city center has also received recognition from citizens. 

 

Environmental: Finally, considering environmental factors. The city's sanitary landfill adopts anaerobic sanitary landfill method, and the leachate meets the standards before being discharged. Moreover, supervision of the treatment of municipal household waste and the cleaning and transportation process of waste will be implemented, and the abandonment and scattering of waste during transportation will be strictly prohibited.We have established a gas emission and recovery system for urban domestic waste landfills, and carried out terminal treatment of the exhaust gas emitted from landfills. The biogas generated when garbage is landfilled can be used as energy, achieving the resource utilization of garbage treatment. Due to its simplicity, low cost investment, operation and management, the landfill method.

 Direction

For a long time, garbage disposal has been the sole responsibility of the government and public sectors. However, due to the long-term reliance on a single public welfare model, garbage disposal has always faced problems such as insufficient investment, incomplete systems, and large urban-rural disparities, which cannot adapt to the pace of social development. Faced with this situation, in order to break through the phenomenon of garbage surrounding cities, we need to change our thinking in a timely manner, fully leverage the power of the government, enterprises, and individuals of the public, adjust the industrial structure, limit the development of polluting industries in urban areas, innovate systems, develop high-tech industries, encourage public participation, and improve relevant supporting measures. On this basis, analyze the future direction of domestic waste treatment in the city, propose countermeasures that are conducive to further improving the level of domestic waste treatment in the city, and also provide reference for the treatment methods and strategies of domestic waste in some small and medium-sized cities in China.

Specific Measures

1.Intensify publicity and implement laws and regulations on the disposal of municipal solid waste.

 

2.Introduce the market system and implement the funds and technologies related to the treatment of municipal solid waste.

 

3.Introduce the market system and implement the funds and technologies related to the treatment of municipal solid waste.
