Description
Technical field
The invention belongs to technical field of waste treatment, particularly relate to a kind of villages and small towns technology for harmless disposal of domestic garbage.
Background technology
House refuse, refers in daily life or provides for daily life the solid waste produced in the activity of service and law, administrative regulation to specify to be considered as the solid waste of house refuse.House refuse generally can be divided into four big classes: recyclable rubbish, garbage, Harmful Waste and Other Waste.Conventional waste disposal method mainly has comprehensive utilization, sanitary landfills, burning and compost.Rubbish is carried out classification retrieval management, it is possible to effectively reduce pollution, increase the recycling of recyclable rubbish.According to the regulation in " the anti-method for the treatment of of People's Republic of China's pollutant of solid-waste environment ", house refuse refers in daily life or provides for daily life the solid waste produced in the activity of service and law, administrative regulation to specify to be considered as the solid waste of house refuse.
Show according to " life in China garbage disposal industry development prospect and the prediction of investment forecasting analysis report " data, along with economical developing rapidly, constantly the increasing and the raising day by day of living standards of the people of population, the generation amount of China's house refuse also sharply increases, very big burden is caused to environment, have impact on the basis of sustainable development, constrain the further development of national economy.How following innoxious, minimizing and resource principle and these rubbish are processed by target, fundamentally solving rubbish becomes, to the harm of environment, the problem that present society all circles extremely pay close attention to.Especially for
China's domestic rubbish disposal industry is started late, but by fast development in recent years, China's garbage disposal industry also begins to take shape, and industry just progressively strides forward to the period of maturation from the growth stage.Along with the continuous aggravation of domestic rubbish disposal industry competition, domestic outstanding domestic rubbish disposal enterprise more and more payes attention to the research to industry market, the particularly further investigation to Business Development Environment and customer demand Long-term change trend.Just because of this, large quantities of domestic outstanding domestic rubbish disposal enterprises emerge rapidly, are increasingly becoming the outstanding figure in domestic rubbish disposal industry.
House refuse generally can be divided into four big classes:
One, recyclable rubbish.Including stationery, metal, plastics, glass etc., recycled by integrated treatment, it is possible to reduce pollute, save resource.850 kilograms of paper can be made as often reclaimed 1 ton of waste paper, save 300 kilograms of timber, produce than equivalent and reduce pollution 74%；Often reclaim 1 ton of plastic beverage bottle and can obtain 0.7 ton of secondary raw materials；Often reclaiming 1 ton of scrap iron and steel and can refine steel 0.9 ton, save cost 47% than with ore smelting, reduce air pollution 75%, the water reducing 97% pollutes and solid waste.
Two, garbage.The foodstuff refuse such as including leftovers, leftovers, bone, dish root, dish leaf, through biotechnology treatment in situ compost, per ton produces 0.3 ton of organic fertilizer.
Three, Harmful Waste.Including refuse battery, waste daylight lamp tube, useless mercurial thermometer, Expired drug etc., these rubbish need specific safety to process.
Four, Other Waste.Including the brick and tile pottery except above-mentioned a few class rubbish, dregs, toilet waste paper etc., it is difficult to the garbage reclaimed, takes sanitary landfills to be effectively reduced the pollution to subsoil water, surface water, soil and air.
The harm of house refuse probably has following five aspects:
1. plastics: be difficult to decompose, destroy soil property, make plant growing reduce 30%；Polluted underground water it is likely to after landfill；Burning can produce harmful gas.
2, battery: button cell contains toxic heavy metal hydrargyrum；Rechargeable battery contains harmful heavy metal cadmium；Aneroid battery is mercurous, plumbous and the environmentally harmful material such as acid-base class material.
3, surplus meal: grow mosquitos and flies in a large number；Promote the antibacterial amount reproduction in rubbish, produce toxic gas and biogas, cause rubbish to explode.
4, paint and pigment: the paint containing organic solvent can cause headache, allergy, stupor or carcinogenic；It is dangerous inflammable thing；How containing heavy metal in pigment, health is unfavorable.
5, cleaning class chemical drugs: containing the petrochemicals of organic solvent or the Nature difficult degradation；There is corrosivity；Chloride element (such as bleach, floor lotion etc.), human body is poisonous；Medicine is containing ozone-layer depleting substance；In insecticide, there are about 50% containing carcinogen, some can damaged animal liver.
At present life is come and processing mode include following several:
1, landfill disposal.Landfill is the effective ways of villages and small towns house refuse of dissolving in a large number, is also the final processing method of all garbage treating process residues, the commonly used direct landfill method of China.So-called directly landfill method is to insert rubbish in ready hole to cover compacting so that it is biology, physics, chemical change, decomposing organic matter occur, reaches minimizing and innoxious purpose.
2, burning disposal.Burning method is to be placed in high temperature furnace by rubbish so that it is a kind of method that middle combustible component is fully oxidized, and the heat of generation is used for generating electricity and heating.
3, compost treatment.House refuse is piled up in heaps, be incubated to 70 DEG C of storages, fermentation, by the ability of microbial decomposition in rubbish, Organic substance resolved into inorganic nutrients.After compost treatment, house refuse becomes health, tasteless humus.Both having solved the outlet of rubbish, and can reach again the purpose of renewable resources, but consumer garbage compost amount is big, nutrient content is low, and cannot be used for agricultural, is only used for greening and waits the industry unrelated with food, so, the scale of compost is seriously restricted by market.
At present, in the vast villages and small towns of China, the processing mode of house refuse is mainly based on simple and easy landfill that technique is the most backward, substantially any effective pollution prevention measure is not taked, causing a large amount of percolate containing high concentration organic contaminant, stench and greenhouse gases to be directly discharged into environment, the health of villages and small towns ecological environment and the safety of drinking water in serious threat.Burning is the another kind of major way of China's villages and small towns garbage disposal, and the outdoor or local method burning disposal mode of main employing, process facility is extremely simple and crude.Owing to villages and small towns rubbish water content is high, calorific value is low, incomplete combustion, not taking any gas cleaning measure in burning process, a large amount of flying dusts that burning process produces, two English, carbon monoxide, the hazardous contaminant such as residue arbitrarily discharge, and cause serious secondary pollution.Villages and small towns house refuse is based on mixed collection, directly biodegradable organic waste higher for moisture content is mixed with other rubbish, not only increase the potential safety hazard of landfill yard, reduce waste incineration calorific value, and serious waste resource, especially the recycling of biodegradable organic waste is seriously ignored.On the other hand, owing to the understanding of domestic rubbish disposal and management deficiency, causing that domestic rubbish disposal disposal technology is extensive single, cause serious secondary pollution, reduction is poor, and resource utilization rate is low, and the environmental problem that villages and small towns domestic rubbish disposal produces becomes increasingly conspicuous.Present stage, the domestic research for the process of villages and small towns domestic garbage resource is more backward, lacks the effective comprehensive treatment technique of mature economy and means.Therefore, efficient and rational villages and small towns domestic refuse resource treatment technology is developed to controlling China's villages and small towns living garbage pollution, it is achieved the minimizing of house refuse, resource, harmless treatment are disposed significant.
