Problems solved by technology

At present, the treatment methods for urban solid domestic waste are mainly incineration and landfill. As far as the incineration method is concerned, it is necessary to build an incinerator and a waste gas treatment system. It still needs to be processed; and the landfill method is more harmful than beneficial, because the waste plastic in the garbage cannot be degraded after hundreds of years
Because there are still some useful things in the garb

Embodiment Construction

[0008] Taking the daily treatment of 200 tons of municipal solid waste as an example, the specific implementation of the present invention will be described in detail. First build a 300-ton municipal solid waste pre-storage seepage tank, and the municipal solid waste containing about 50% moisture will be automatically dewatered and sent from the garbage pre-storage tank to the dryer for drying through the conveyor. The length is 4.5 meters and the width is 0.6 meters. It transports 10 tons of garbage per hour and the power is 2.2 kilowatts. The fuel for the heating furnace of the dryer is mainly provided by the biogas storage tank. Drying, the temperature is controlled at 150-80°C (the front section is high and the back section is low), and ultraviolet rays are used for sterilization and disinfection while drying; it enters the slow flat sorter for primary sorting, and most of the paper is manually sorted , rags, glass, wood, bricks and tiles, waste plastics, waste rubber, was...

Abstract

The present invention is one comprehensive innocuous city solid refuse treating system. In the system, the city solid refuse is first stoved, sterilized and sorted, then magnetically separated to separate out iron containing waste, and finally sieved into the undersize fed to one mixing tank and the oversize further sorted, with the rest matter being crushed and fed also to the mixing tank for fermentation to produce organic fertilizer. The sorted fabric, paper, iron, glass are reused; the sorted building refuses are crushed and further produced into no-burning brick; the waste battery is specially treated; the waste plastic and rubber are treated to produce oil; and the marsh gas generated in the fermentation process is used to provide heat for stoving refuse and refining oil. The present invention has excellent refuse treating effect.

Description

1. Technical field [0001] The invention relates to a comprehensive treatment method for urban solid waste. 2. Technical Background [0002] With the development and progress of society, the process of urbanization in my country is accelerating, how to deal with municipal solid waste is a very important issue. At present, the treatment methods for urban solid domestic waste are mainly incineration and landfill. As far as the incineration method is concerned, it is necessary to build an incinerator and a waste gas treatment system. It also needs to be processed; and the landfill method is more harmful than beneficial, because the waste plastics in the garbage cannot be degraded after hundreds of years. Because there are still some useful things in the garbage, all incineration or landfill also causes a waste of resources. In recent years, some people have also invented some municipal solid waste treatment equipment, but the design of these equipment is mostly immature, and t...
