Background technology
Green building, bio-toilet concept put forward many years, but carry out it is relatively difficult, main reason is that at This height and supporting technology are immature, and also relevant policies is not perfect.The excreta that lavatory comes out at present is directly discharged into lower water In pipeline, underground water seriously polluted.Bio-toilet technology is primarily upon it and enters water aspect, and the processing for excreta is also letter The gas direct emission of generation still will produce gaseous contamination by single compost treatment in this way.
Invention content
It is an object of the invention to propose a kind of excreta recycling system.It can be in new rural village or tourist district, life The setting of the place such as state area.
It is realized especially by following technological means：
A kind of excreta recovery system, including toilet seat, the water storage device on toilet seat top, the dehydration being connect with water under toilet seat Device, the composting device being connect with dehydration device lower part, the marsh gas treatment device being connect with dehydration device side.
The human feces that toilet seat flows into are separated by solid-liquid separation by the dehydration device by high speed rotation, including top is set The wind turbine set carries porous cylindric inner cylinder and cylindric outer barrel, and the cylindric inner cylinder lower part is provided with solid matter Outlet is connect with composting device, and the cylindric outer barrel lower part is provided with liquid effuser and is connect with marsh gas treatment device, described The human feces that the wind turbine of top setting is used to flow out toilet seat carry out certain air-dried processing.
The composting device makes it through dry type Anaerobic Treatment and obtains organic fertilizer for handling dewatered solids substance；Packet Include circulating water chennel, dry type anaerobic reactor, inoculation chamber, moisture trap and acidification gas air accumulator.
The marsh gas treatment device is used to form methane liquid manure and biogas residue, including USR anaerobic fermentation devices, sulphur removal dress It sets, purifier and biogas storage device.
Dry type anaerobic reactor internal upper part in the composting device is provided with spray equipment, and bed course, bed course is arranged in lower part Water outlet is arranged in lower part, and water outlet is connected with the entrance of circulating water chennel, and gas outlet is arranged in dry type anaerobic reactor top, Gas outlet is connected with the entrance of acidification gas air accumulator；The outlet of the acidification gas air accumulator and the sulphur removal of marsh gas treatment device fill Posting port is connected；
In the desulfurizing device using sulfur bacteria biological oxidation by the Oxidation of Hydrogen Sulfide in biogas be sulfurous acid and sulfuric acid, To be removed from biogas；Grain size in biogas is more than 3 microns of impurity removal by the purifier by way of filtering.
The temperature of the dry type anaerobic processing device is promoted to after 35 ~ 38 DEG C of progress fermentation process, in 50 ~ 60 DEG C of temperature Under, compost forms organic fertilizer after 12 ~ 18 days.
The cylindric inner cylinder and cylindric outer barrel of the dehydration device are all made of corrosion resisting steel, the chemistry of the corrosion resisting steel Ingredient is by weight percentage：C：0.06 ~ 0.09%, Si：0.36 ~ 0.39%, Mn：0.8 ~ 1.2%, Nb：0.02 ~ 0.08%, Ti： 0.02 ~ 0.06%, Ni：0.2 ~ 0.6%, Al：0.05 ~ 0.10%, V：0.03 ~ 0.08%, Cr：0.5 ~ 1.1%, Mo：0.38 ~ 0.60%, Cu：0.2 ~ 0.5%, B：0.001 ~ 0.003%, Ce：0.02 ~ 0.06%, P<0.02%, S<0.01%, N<0.001%, surplus be Fe and Inevitable impurity；The percent by volume of tempered sorbite+tempered martensite is 82 ~ 90% in its microstructure.
The biogas storage device is connect with Biogas Generator Set.
The lower water phase that the water inlet of the water storage device on the toilet seat top cleans pond with washroom face is connect.
Effect of the invention is that：
1, after being separated by solid-liquid separation lavatory excreta, solid matter is fermented, compost forms organic fertilizer, liquid object Matter is purified liquid water by fermentation, the isolated biogas of liquid gas and liquid water, by water process to obtain middle water, i.e., will row It lets out object to be handled completely, carried out recycling and without generating new pollutant, realizes and completely clean nuisanceless lavatory.
2, by the way that the configuration mode between each device and the specific set-up mode of each device is rationally arranged so that whole The more perfect processing excreta of body flow.
3, since dehydration device is first device of processing unit, long-term residing environment is excreta and sewage, one As metal material can not reach corrosion resistant effect to the specific substance, but if using common stainless steel, at Originally it increases substantially, therefore its constituent content is improved so that the corrosion resisting steel is not adding expensive element largely In the case of, can the resistance to particular surroundings corrosion, to greatly improve device entirety durability degree.
