Process Introduction
Screening treatment of domestic waste serves as the core pretreatment link for the resource utilization, reduction, and harmless disposal of waste. Relying on mechanical screening technology, mixed waste is accurately classified and separated according to differences in particle size, density, and morphology, laying a foundation for subsequent targeted disposal.
Core Process Flow
Pretreatment Bag Breaking
Automatically break open bagged waste to loosen and homogenize materials, preventing equipment blockage caused by wrappers.
Multi-stage Screening and Classification
Adopt combined equipment including drum screens, bouncing screens and vibrating screens to separate fine organic matter, combustibles, inert materials and large sundries by particle size.
Fine Sorting and Purification
Cooperate with magnetic separation, air separation and intelligent sorting technologies to recover high-value recyclables such as metals and plastics, and separate harmful components.
Targeted Diversion and Disposal
Organic materials enter composting or anaerobic fermentation biogas production systems; combustibles are used for incineration power generation; inert materials are applied to landfill covering or building material resource utilization; hazardous waste is subject to separate safe disposal.
Application Scenarios
Urban domestic waste transfer stations, pretreatment links of incineration plants, excavation treatment of aged waste in landfills, mixed treatment of kitchen waste and other waste, centralized disposal of domestic waste in villages and towns.
Advantages of Domestic Waste Screening Treatment Solutions
Remarkable Reduction Effect Screening separates fine sandy soil and inert aggregates, reducing landfill or incineration volume by 30%–50% and extending the service life of treatment facilities. It reduces the production of incineration slag and fly ash, alleviating the terminal disposal load.
Greatly Improved Resource Utilization Rate Efficiently recover high-value materials such as metals, plastics and paper, with a resource utilization rate of over 85%. Pure organic matter can be used for fertilizer production and biogas generation, and combustibles can improve incineration calorific value and power generation efficiency.
Efficient Treatment with Controllable Costs Automated continuous operation, with a single equipment processing capacity of 50–150 tons per hour, and treatment efficiency far higher than manual sorting. The per-ton treatment cost is reduced by more than 60% compared with manual sorting, and equipment energy consumption is lowered by 15%–20%.
Environmentally Friendly and Safe, Reducing Secondary Pollution Adopt a fully enclosed structure equipped with dust removal and spray systems to suppress the spread of dust and odor, and control the leakage of leachate and malodorous gas. Separate hazardous waste in advance to avoid heavy metals and toxic substances from mixing into incineration or landfill links, reducing the risk of soil and groundwater pollution.
Strong Adaptability and Stable Operation Adopt a modular combined design, which can flexibly adapt to different scale demands with a daily treatment capacity of 50–3000 tons. The screen aperture is adjustable, capable of adapting to waste in dry/wet conditions and with complex components, with a screening purity of 90%–95%.
Extended Service Life of Back-end Equipment Reduce abrasion of crushers and incinerators caused by sand, gravel and hard sundries, lowering equipment failure rate and maintenance costs. Realize homogenized material feeding, making subsequent processes such as incineration and composting operate more smoothly.
