Abstract
The invention discloses a treatment method for freezing night soil, which relates to treatment methods such as collecting, storing, transporting and processing in the way of freezing or collecting manure from the night soil, wherein, new night soil is cooled and frozen at the temperature of minus 5 DEG C, collected in the condition of freezing, stored and transported, and finally is subjected to harmless treatment. The treatment method not only saves a large amount of precious water resources, and reduces the bottleneck pressure of water resources shortage in the urbanization process, but also reduces pollution to down-stream ecology caused by wastewater produced in the urbanization process, meanwhile, has great economic significance on the precious soil resources. The treatment method is novel and unique, not only has practical functions, nut also meets the need for sustainable development economy, and is suitable for being used as the final proposal for treating the night soil in urban development in future.
Description
Technical field
The present invention relates to freezing mode collect, store, transportation, processing or to treatment process, especially faeces freezing treatment methods such as soil collected manures.
Background technology
Tradition ight soil is handled and is generally simple and easy non-irrigated lavatory, and southern water system is enriched also reliable river, area water normal erosion situation, but sanitary condition is generally relatively poor.
Along with the urbanization development, population gathers in a large number, water resources, the land resources growing tension, rare, even in prior art, the civilian dress of separating commonly used is put and is generally flushing toiler, consume great lot of water resources, handle 1 kilogram of ight soil mean consumption 15 kg of water according to estimates, wash away the sewage of ight soil, flow to the downstream, city through urban discharging pipeline, still need bigger input to carry out sewage disposal, according to estimates, because sewage disposal drops into wretched insufficiency, still have the municipal effluent more than 70% can not obtain handling, directly outdoor storage or accumulate in the lower reservoir is used for agricultural irrigation, even has the human sewage reservoir to be engaged in aquaculture, this economic structure, belong to typical pollution vicious cycle pattern, final in water and soil earth resource cost, contaminate environment is so that to human health, existence causes lasting negative impact.Thereby change this traditional dejecta treatment method, it also is the major issue that is related to human survival and development from now on, at present, have higher requirements for environmental health, but when lacking the water source, also have multiple new technical scheme open, such as, the mobile public toilet that has adopts packed processing, or adds chemical substance processing etc., but generally can not better realize economizing on water and reduce the purpose of peculiar smell.
Summary of the invention
The objective of the invention is to, propose a kind of can either the conserve water resource, have simultaneously and reduce ight soil as far as possible and handle the dejecta treatment method that environment is polluted, i.e. faeces freezing treatment method.
Technical scheme of the present invention is: new ight soil is lowered the temperature, freezing below-5 ℃, compile under freezing state, accumulating, and finally carry out harmless treatment.
The present invention is with freezing mode, to ight soil collect, accumulating and harmless treatment, a large amount of precious water resource had both been saved, alleviated water scarcity bottleneck pressure in the urbanization process, alleviated simultaneously of the pollution effect of urbanization process sewage again, the soil resource of preciousness has also been had important economic implications simultaneously downstream ecology.Treatment process novelty, uniqueness, existing realistic function meets the requirement of sustainable development economy again, and is suitable in the development of future city, handles the final plan of ight soil.
Embodiment
Embodiment 1: new ight soil is lowered the temperature, freezing below-5 ℃, compile under freezing state, accumulating, and finally carry out harmless treatment.
Particularly the present embodiment technical scheme can be used under the environment of anhydrous or serious water shortage, as vehicles such as aircraft, coach flights, and as flowing or interim public lavatory that big assembly is built, as when treasuring in the wilderness area scientific investigation, or the like.
New ight soil temperature is approaching with normal body temperature, be generally about 37 ℃, in defecate 15 minutes, with envrionment temperature level off to consistent, but in the ight soil discharge process and get rid of in back 5 minutes, the cadaverine foul odour of filth can pollute surrounding environment.
Therefore, in the process that new ight soil is being discharged, cooling rapidly from about the envrionment temperature to 5 ℃ is kept 5 ℃ of left and right sides temperature to defecations then and is finished in 30 seconds, or from about 5 ℃ to progressively slowly cooling below 0 ℃.
After defecation is finished, in 30 seconds, carry out fast cooling, and it is solid-state to keep freezing real one-tenth fully to ight soil in 1 minute to freezing feces below-5 ℃.
The ight soil coating material for temporarily water-fast, through freezing slightly the tool insulation, and the film material that can degrade.As regenerated papermaking etc.
Freezing to ight soil adopts the motor driven compressor refrigeration.
Perhaps adopt, freezing to ight soil adopts the chemical process refrigeration.As ammonia refrigeration etc.
Refrigerated is solid ight soil, collects under keeping warm mode, stores, transports.
With the freezing solid ight soil that is, send into that source mill pulverizes, drying under cold condition, make fertilizer.
With the freezing solid ight soil that is, directly imbed in the heatable adobe sleeping platform that digs out in advance.The soil that such heatable adobe sleeping platform can make crop rotation rest and reorganize also can be just in the farmland or the forest belt of farming, through after a while, after the biological degradation, kind of plant or trees, realizes free of contamination biological cycle economic model on this such soil.
The embodiment of the invention, with freezing mode, to ight soil collect, accumulating and harmless treatment, a large amount of precious water resource had both been saved, alleviated water scarcity bottleneck pressure in the urbanization process, alleviated simultaneously of the pollution effect of urbanization process sewage again, the soil resource of preciousness has also been had important economic implications simultaneously downstream ecology.Treatment process novelty, uniqueness, existing realistic function meets the requirement of sustainable development economy again, and is suitable in the development of future city, handles the final plan of ight soil.
