Abstract

The invention relates to a garbage-drying and deodorizing and percolate-disposing system and method. The garbage-drying and deodorization and percolate-disposing system comprises a garbage-drying device, a deodorizing device and a percolate-disposing device, wherein the garbage-drying device comprises a garbage-drying region, a movable cover plate is arranged above the garbage-drying region and connected with a motor, a grabbing jaw is arranged above the movable cover plate, a ventilation isolation layer, a ventilation air pipe and a grid plate are arranged at the bottom of the garbage-drying region; and the percolate-disposing device comprises a percolate water-collecting basin, a pretreating basin, a heater, an anaerobic reactor, a nitrification / denitrification device, an ultrafiltration membrane device, a nanofiltration membrane device and a reverse osmosis membrane device. The method comprises the following steps: S1, drying garbage; S2, biologically deodorizing; S3, lifting and conveying percolate; and S4, disposing the percolate. According to the garbage-drying and deodorizing and percolate-disposing system and method, multiple links of disposing the garbage are improved, and thus garbage drying and percolate disposing efficiencies are improved, and the effect of biologically removing bad smell and microorganisms from the garbage is improved. The disposed tail gas and percolate can be emitted when reaching the standard.

Description

technical field [0001] The invention relates to the field of garbage treatment, more specifically, to a system and method for drying garbage, deodorizing and treating leachate. Background technique [0002] The treatment and utilization of municipal waste "harmless, reduced, and resourceful" is a worldwide issue. At present, the centralized treatment methods of urban and rural municipal waste in my country mainly include landfill, composting, and incineration. The landfill method occupies a large area and has a low degree of waste reduction. It requires anti-seepage treatment, and a biogas recovery and leachate treatment plant must be built, which is likely to pollute groundwater and surrounding air. The composting method is suitable for treating waste containing a lot of perishable organic matter, and can realize the comprehensive utilization of some resources, but the quality of composting is not easy to control, and the harmful components often exceed the standard. Wast...
