Description
Technical field
The invention belongs to organic solid castoff and clean processing and comprehensive utilization of resources field, particularly house refuse cleans processing method.
Background technology
At present, three kinds of methods are adopted in domestic rubbish disposal both at home and abroad basically: burning, compost, sanitary landfill method, also have the 4th kind of method, and be exactly the comprehensive treatment method of so-called above-mentioned three kinds or two kinds method combinations.Burning method is innoxious more thorough through high temperature incineration, but the flying dust that produces 3%-4% contains the dangerous material discarded objects such as dioxin and heavy metal that exceed standard, need after-treatment, the method method of after-treatment has the high-temperature fusion that surpasses 1000 ℃ to make it vitrifying, plastics fusion embedding, adds the cement embedding behind the stabilizing agent, in a word, after the processing, need the secondary landfill disposal, cost is very high.Burn the lime-ash that produces 15%-20% and need landfill disposal, or transport outside the factory, do other utilization.It is strong carcinogenic substance that the flue gas that burning method produces contains dioxin, needs the high temperature through 1200 ℃ through the dual firing chamber of incinerator, and the time of staying is not less than 2S, and the dioxin branch is taken off.So far the dioxin that exceeds standard both at home and abroad discharging, burning method is quite a lot.Burning method also wastes energy, and the employing burning electricity generation that has reclaims electric energy, but has only 30% just to be converted into electric energy in the heat energy, and 70% heat energy is not utilized, and has slatterned.Original useful resource can directly be recycled in the rubbish, or handles the back and recycle, and can burn but to have wasted.The burning method investment is very high, and operating cost is also very high.
Composting process was carried out compost fermentation with 20 days-30 day time with rubbish exactly.Aerobic compost and anaerobic composting are arranged; Also have aerobic and the compost anaerobism combination; Static compost and dynamic compost are arranged.In a word, utilize the natural microorganisms in the house refuse to carry out lengthy fermentation exactly, the high temperature that produces more than 55 ℃ is killed most of disease bacterium and worm's ovum, but resistant to elevated temperatures bacillus is not gone out.It is dead to give birth to life and death through natural microorganisms, the long-time compost fermentation that goes round and begins again, most nutriments in the rubbish have been exhausted, the only remaining difficult humus that utilizes again and the inhibitory substance of microbial death thalline and generation are microbial toxin, make microorganism can not continue the heat production of fermenting again, so-called stabilisation that Here it is has been finished the whole process of compost fermentation.Because the perishable organic matter in the rubbish consumes in a large number, become the greenhouse gases volatilization, make about waste reduction to three/one.But heavy metal wherein can not be decomposed by microorganism, and volatilization and is stayed in the garbage compost, make it to be concentrated, increment nearly about three times.Compost contains heavy metal amount height, contains the microbial toxin height, contains the harmful bacillus category that is difficult for being killed, and can not do agricultural fertilizer.For a long time, garbage compost is used as the nutrition soil or the soil conditioner of greening usefulness both at home and abroad.But in recent years, the U.S., the soil conditioner of greening usefulness is not advocated to make of garbage compost in Europe.For avoiding ecological risk, can only be used as the overburden soil of landfill factory.Just carry out landfill disposal.Also produce a large amount of toxic and harmfuls in the composting process, as greenhouse gases and foul gas, make mosquitos and flies parasitic in a large number, environmental sanitation is very poor, and epidemic infectious diseases very easily takes place.Compost easily produces fuel gas, CO, H
2, CH
4, burning and blast often take place.
Sanitary landfill method is the another kind of form of compost fermentation method, and its Biological Principles is similar with fermentation method.Produce not easily biological-degradable of percolate, need with materialization and biochemical Combined Treatment, operating cost is very high.Landfill produces inflammable biogas and often burns, blast.Landfill method takies a large amount of soils, waste land resource.Because security consideration, after the closing, except that greening, can not do any utilization in 10 years.The same in the landfill process with compost, produce a large amount of toxic and harmfuls, greenhouse gases and foul gas have a large amount of mosquitos and flies parasitisms, easily produce epidemic infectious diseases.
