Description
Technical field
The utility model relates to domestic rubbish disposal, specifically is a kind of house refuse biological organic matter liquefaction-biochemical treatment apparatus.
Background technology
Up to now, the tupe of China's application of city life garbage mainly contains these three kinds of methods of landfill method, composting process and burning method.
Landfill method: simple, be waste disposal method the earliest, its principle be with rubbish in selected place, landfill adds cladding material to certain altitude, lets it pass through long-term physics, chemistry and biological agent and reaches stable state.The ratio that landfill method accounts for the existing processing method of China is about 90%, is tradition and prevailing model that application of city life garbage is handled.With air storage, landfill is that the landfill method of characteristics has taken valuable land resource; Subtract the appearance weak effect; Existence causes the danger of serious secondary pollution to soil, surface water, underground water and surrounding air, says that from environment protection significance it is a kind of emergency measure of passiveness.After country was to the landfill method standardization, the requirement of place capital construction, percolate long-term disposal and input were higher, and operating cost also increases considerably, and the low cost movement of traditional burying method will be no longer feasible.
Composting process: be that the rotten organic matter of piling in the rubbish is carried out compost treatment, improve a kind of approach that garbage regeneration utilizes level.Rely on microorganisms such as the extensive bacterium that distributes of nature, actinomyces, fungi, controlledly promote biodegradable organic matter to transform to stable humus.It has dual mode: artificial compost and mechanization compost.Must carry out preliminary treatment and post processing during compost treatment, unfermentable composition need be made landfill or burning disposal in the rubbish.At present, the city compost field of having built up and having moved is few, mainly adopts mechanization compost and simple and easy During High-Temperature Composting technology.Because the composting technology facility is comparatively backward, the composting production of production is of low quality, fertilizer efficiency is lower, makes the composting production slack market.
Burning method: be that the abundant oxidation of combustible component finally becomes harmless stable lime-ash with the process combustion reaction under high temperature (800 ℃～1000 ℃) condition of the combustible component in the rubbish.Burning method can make rubbish subtract appearance significantly, has reduced taking, and can round-the-clockly operate, and can reclaim heat energy and be used for life heating and generating, be in the world-garbage treatment technology that a little developed countries extensively adopt.But burning method is promoted in China and also had many problems: 1, the burning method investment is big, and the occupied fund cycle is long; 2, the calorific value that burns rubbish has certain requirement, generally can not be lower than 5000kJ/kg, has limited its range of application; 3, " dioxin " problem that produces in the burning process must have very big fund input just can effectively handle; 4, there is very big dispute at present domestic townm refuse is burned, and a plurality of cities cause the expert and the common people's strong query because of building incineration plant, be illustrated in technical, manage and also have a series of unsolved problems.
