Municipal Solid Waste Management Problems And Solutions
After years of investment and research and development, Guoxin has launched domestic waste sorting and processing equipment and production lines to solve the problem of urban waste, which has successfully solved some urban waste treatment problems.
Screening and sorting is the primary link in the follow-up treatment of domestic waste. To effectively utilize the beneficial components in the waste, first of all, the organic matter, combustible matter, metal, plastic, etc. in the waste must be well classified and separated. Based on the characteristics of ingredients and practical experience, a domestic waste classification and treatment production line has been launched.
Its process is roughly as follows:
1. When the garbage enters the factory, it is first unloaded to the unloading platform, sent to the slat conveyor by the loader, and then conveyed to the manual sorting platform by the belt conveyor, where the large items and harmful garbage in the garbage are sorted out by the cleaners.
2. The garbage after manual sorting enters the bag breaking machine, and the bagged garbage in the garbage can be torn apart by breaking the bag, which is convenient for subsequent processing.
3. The garbage after the bag is broken is sent to the drum screen by the belt conveyor for processing, the organic matter is picked out, and the iron is selected by the suspended magnetic separator.
4. The material on the sieve adopts the magnetic separation method, which can pick out the iron particles in the sieve and send it to the comprehensive air separator for air separation. Paper and other flammable materials are separated.
5. According to the needs of customers, with appropriate manual sorting, flotation, washing, color sorting and cyclone sorting, etc., the separation of different substances in the garbage can be realized.
The domestic waste sorting system equipment of this project is sorted according to the characteristics of the waste materials, which can make all kinds of waste materials sorted out with high cleanliness and less impurities, and realize the "three-points of harmlessness, reduction and resource utilization". To make full use of domestic waste sorting. Seek the reuse of resources from both social and environmental aspects, in order to achieve the coordination and unity of sustainable economic and social development and environmental protection. This project can separate five categories of muck, solid, waste plastic, residual organic matter and iron products at one time. The equipment used all adopts the current domestic advanced technology, that is, high reliability, strong operability, maintainability and scalability. The device is suitable for sanitary landfill and treatment of municipal solid waste, pretreatment process of domestic waste transfer station, pretreatment process of domestic waste incineration, pretreatment process of domestic waste incineration, waste composting process, etc. Reduce waste turnover and inventory. At the same time, it is also necessary to strictly implement relevant national and local laws, regulations and relevant standards, reduce pollution, change waste sorting technology, and change waste sorting technology in principle. All kinds of garbage sorted in this project have realized the reuse of resources, which meets the requirements of resource utilization and the development of circular economy.
