Description
Technical field
The present invention relates to a kind of environmental sanitation technical field, refer to especially domestic waste comprehensive utilization and processing method.
Background technology
Along with the fast development of urbanization process, the processing of domestic waste has become the difficult problem that each city of restriction promotes image and sustainable development.At present, the waste disposal method of domestic routine mainly contains: landfill method, composting process and burning method.The defect of the whole bag of tricks is all more obvious, for example: landfill method exists contaminated environment, takies the defect of a large amount of land resources, and applied value reduces gradually; The composting process of composting process is difficult to control, larger to the secondary pollution risk in bad border, incomplete to organic utilization, fertilizer complicated, and the factor such as minimizing is less, will progressively be eliminated; Combustible content >=5% in the slag of burning method, hot burn decrement rate >=3% of slag, operation processing cost is high, and the tail gas of discharge is difficult for up to standard, and the violent in toxicity dioxin emission amount especially containing in tail gas is not up to standard for a long time, has seriously hindered technical development.
The reason that causes above-mentioned situation is determined by the feature of Municipal Solid Waste in China composition.Be subject to the impact of consumption habit and environmental consciousness, the rubbish of external most of developed countries is thrown in and collection method is classification reception, entering rubbish before incineration plant by good classification, and the kitchen in rubbish is remaining and hogwash class amount of substance is less, moisture and putrescible matter are lower, packed standard, is to burn to utilize and has created good condition.And in China, the collection method of rubbish is traditional mixing and receives, kitchen content remaining and hogwash class material in rubbish is higher, moisture and putrescible matter are higher, packed also lack of standardization, raw refuse is almost " bag in bag " form and throws in, and in bag, material composition complexity cannot be classified, in industry, this class rubbish of common name is " high humidity composting ", and this class composting possesses following characteristic:
1, calorific value is low: the design refuse thermal value of common incinerator is more than 1200kcal/kg, and now the domestic waste of China is not classify to mix and receives, and kitchen is remaining, the content of dregs etc. is up to more than 60%, so its calorific value is difficult to reach design load.
2, moisture is high: due to more than the kitchen in rubbish, the moisture of the fresh body of plant etc. is all more than 65%, so under normal circumstances, the moisture in the domestic waste of China is all more than 50%, at plum rain season or its limit moisture of rainy day up to more than 70%.
3, packed reception lack of standardization, rubbish form, calorific value are inhomogeneous: the house refuse of domestic city is almost the packed reception of not classifying, and the component of rubbish is very complicated, and all gap is larger for its physical aspect, calorific value, distribution space, chemical form etc.
