Nowadays, most countries in the world have taken how to effectively deal with urban waste as an important issue of research, showing that its impact on the environment. In the current process of dealing with urban waste, Beston Group has widely applied the sorting technology, which is a key part in municipal solid waste disposal. It will not only help make progress and innovate in the road of sustainable development, but also is a future development trend of environmental protection, worthy of further study.
– Overview of sorting techniques
Garbage sorting refers to the process of separating the waste materials that are recyclable or not conductive to the subsequent processing and disposal by means of various methods. This is an important aspect in municipal solid waste treatment project.
– Selection factors
The garbage sorting technology has been studied and put into use for many years, and has achieved satisfactory results in these years’ practice. Different cities have different factors to consider when choose the waste disposal classification technology. Mainly pay attention to the following points:
Firstly, whether there is a certain understanding of the general situation of the city;
Secondly, whether the local technology can meet the sorting requirement;
Thirdly, whether the local government or bank will provide economic and financial support for the sorting technology;
Fourthly, how about the local environmental factors;
Finally, the related legal and policy factors.
Each city should have a comprehensive and detailed analysis of these five points in the choice of the program, to make a specific evaluation. On the basis of the five points, combine with the advantages and disadvantages of garbage separation technology. In short, find out the most suitable solid waste treatment equipment for the local situation combining with the actual situation.
For example, for some of the more complex components, the waste sorting machinery can not distinguish it from the garbage, so it is necessary to use manual sorting; this kind of technology is suitable for the region where the recyclable resources occupied a large proportion; screening technology is mainly applied in the region where there is a lot of organic matter or the garbage contains a lot of moisture; gravity sorting technology has a long history of development, with smaller investment, so it can be widely applied in many regions, especially in small and medium cities; some cities are famous for its large metal containing and the industry is more developed, so the magnetic sorting technology can be selected.
Prospects of technological innovation in environmental protection industry and waste separation
In recent years, given the deterioration of world’s ecological environment, most countries have adopted a number of governance measures and some basic measures, including the active development of environmental protection industry. With the rapid development of world’s waste production, we particularly need to rely on technological innovation methods to accelerate the most effective and economic treatment on garbage. In any case, make the “waste” truly become “treasure” to achieve the resourcing of garbage, which is the critical and fundamental point of waste treatment technology. In order to further improve the technological level of municipal solid waste sorting in the city, it is necessary to optimize and innovate the resource allocation of municipal solid waste sorting technology, improve its sorting efficiency and sorting precision, reduce system construction cost and running energy consumption, material consumption and management input. Adopting optimized and innovative municipal solid waste management equipment can extend the service life of landfills; the harmful ingredients are separated and safe to dispose, so that the landfill pollution on the environment will be greatly reduced; the ecological environment of the city will be improved; the health and industrial and agricultural production of the residents near the landfill are protected, which is the most fundamental starting point for the development of the technology.
