Municipal Solid Waste Landfills Treatment Equipment Resource Treatment Technology

Comprehensive treatment technology of live waste is the core to realize harmless, reduction and resource treatment of waste. Its main purpose is to effectively separate components of different types, sizes and specific gravity in waste through sorting, screening and crushing. Thus, the parts with high calorific value are incinerated, the biochemical treatment containing organic matter is carried out, the recyclable ones are recycled, and the non-utilizable resources are then landfill treatment.

According to the component characteristics of municipal solid waste, the main components are separated from other components, and the selection and analysis of the separation process: inorganic substances are mainly completed by screening means. For the inorganic compounds dominated by gray soil, disk screening or roller screening can be used for screening. Most of the gray soil enters the material under the screen, and other components enter the logistics on the screen. For inorganic components such as bricks, ceramics and coal slag, they can be separated from other materials by a bouncing separation process.

municipal solid waste landfillsmunicipal Comprehensive treatment and reuse of solid waste landfills has the following advantages:

(1) Waste reduction can obtain land resources and make landfills reusable. Through the comprehensive waste treatment process, the capacity of waste can be reduced, and the ecological recovery of the landfill site can be realized, so that the original land can be redeveloped. Under the situation of increasingly tight land resources, the treatment of municipal solid waste landfills has great market potential.

(2) Harmless waste can eliminate the pollution of landfill sites to the surrounding environment and groundwater, especially the original large number of informal landfills, due to the failure to take effective protective measures during the operation period, the water, gas and odor pollution generated not only has a serious impact on the lives of surrounding residents, but also has caused harm to groundwater. Through the comprehensive treatment of municipal solid waste landfills, the original pollution sources have been effectively eliminated, the ecological environment has been improved, and huge environmental and social benefits have been realized.

The classification and resource treatment process of landfill domestic waste is characterized by following the following steps:

1) Dig up: first dig up the garbage in the landfill through the excavator;

2) Sorting: the garbage is transported to the first-level belt conveyor through the feeder, the path of the first-level belt conveyor is equipped with a magnetic device, the feeder is equipped with a broken bag, this step is set up manual sorting and magnetic sorting, manual sorting out large garbage, magnetic sorting out iron garbage;

3) First-level screening: the garbage after sorting is transported to the first-level drum, the first-level drum is provided with a number of fixed hooks to break the bag twice, and the first-level drum is provided with a number of large sieve holes to screen the first-level sieve and the first-level sieve;

4) Secondary screening: the primary screening material is transported to the secondary drum, the secondary drum is provided with a number of small sieve holes, the secondary screening material is sent to the storage yard to reduce the land, and can also be used as greening and tree fertilizer;

5) Air selection: the first level of the screen into the fan, the fan is provided with positive pressure fan and negative pressure fan, of which the positive pressure fan sorting out more than heavy garbage, negative pressure fan sorting out small proportion of garbage;

6) Incineration: incineration of secondary screen and other combustible organic matter for heat utilization.
