Description
Technical field
The utility model relates to a kind of urban garbage disposal system.
Background technology
At present, the urban garbage disposal mode that extensively adopts both at home and abroad mainly contains 4 kinds of processing modes of sanitary landfills, burning, compost and comprehensive utilization (recycling utilization).
Sanitary landfills is a kind of innoxious final disposal mode of a kind of domestic waste that grows up of handling from traditional stacking and made ground.Its disposal ability is big, does not need rubbish is carried out categorised collection or focuses on, and can collect biogas and generate electricity when garbage loading embeading thickness is enough big, and investment and operating cost are lower.But landfill yard requires high to the factory site, and difficulty is big, and the land occupation resource causes secondary pollution easily, as percolate, landfill gas, flying dust and floating thing etc.Soil water body and atmosphere to the surrounding area affect greatly, and be very big in the neighbourhood social influence, causes the ample resources waste simultaneously.Sanitary landfills is only applicable to the land resource abundance, and implement easily in the landfill place, the area that the local economy level falls behind relatively.At present, domestic most rubbish are to adopt landfill method, but wherein small part is to adopt sanitary landfills, and major part all is to adopt simple and easy stacking.
Burning refer in the house refuse combustible in hot conditions (800 ~ 1000 ℃) through combustion reaction, the abundant oxidation of combustible component finally becomes the process of harmless stabilized ash.Burn minimizing degree height, innoxious effective, heat energy can be used to generating or heat production, reaches the effect of recycling, and floor space is little, and totally enclosed pattern can not be subjected to the influence of natural conditions.But, its shortcoming is one-time investment and operating cost height, the operational management difficulty is bigger, be easy to generate secondary pollution, be difficult to control, have dioxin contamination in the tail gas, in the tail ash heavy metal pollution is arranged, the recyclable resource of waste part, if qualified discharge, high standard waste gas treatment equipment investment operating cost height.It is only applicable to rubbish Lower heat value height, and moisture content is low, the developed area.Developed countries uses often at present, descends to some extent in recent years, and Chinese development in recent years is very fast, but technology is still waiting raising, fails to reach discharge standard.
Compost is to utilize microorganism to promote the Biochemical processes that biodegradable organic matter transforms to humus in the house refuse artificially, and the product after the processing is compost.It can take full advantage of organic matter in the rubbish, and composting production can be used for fertilizer, and secondary pollution is less, control easily, and one-time investment and operating cost are relatively low.But the volume reduction rate of rubbish is low, also has the residue of 30-40% to need landfill disposal, easily produces stench in the composting process, surrounding enviroment is produced pollute, and floor space is relatively large, because the impurity content height of compost, fertilizer efficiency is low, and the fertilizer market is generally bad.Compost is only applicable to labile organic compound composition height in the rubbish, and economic condition is not high, the area that treating capacity is low.Compost is used many in Europe, develop comparatively fast during domestic " the Seventh Five-Year Plan, eight or five ", and successful example is few, and the fertilizer market is poor, is difficult to keep operation, and major part is simple and easy compost, and secondary pollution is big.
Comprehensive utilization refers to adopt suitable method that all kinds of products are handled respectively again to house refuse classification earlier, reaches the purpose of comprehensive utilization of resources, and it integrates all kinds of processing methods.Its advantage is to have realized garbage harmless, resource, minimizing at the bottom of the maximum limit, and secondary pollution is little, and biogas can be used to generating, and fertilizer impurity is few, and investment and operating cost are moderate, and floor space is less.But, wanting to realize fully recycling utilization, its input cost is big, the treatment system complexity that relates to, equipment needed thereby requires high.
