Description

A kind of unpowered composite wastewater treatment box of rural households
Technical field
The utility model belongs to technical field of sewage treatment equipment, more specifically, it is dynamic with nothing to be related to a kind of rural households Power composite wastewater treatment box.
Background technique
Chinese sewage treatment status: Chinese inland and rural area are mainly the ground that sewage disposal system is not yet safeguarded Area.In view of the national conditions of China, wide soil, the geographical environment of water conservancy drop, as a consequence it is hardly possible to build one as Japan A wide area sewage treatment facility, and each house by sewage pipe connection thereunto.Sewage conduct is extended to wide soil Be it is useless, only the construction cost of infrastructure exploitation is exactly astronomical figure, it is evident that its maintenance cost will be to future Administrative budget brings pressure.
According to Rural Areas of China present case, the domestic waste water from poultry and pouity dwelling place is mixed and is poured over neighbouring In water system or at present almost untreated soil.Although natural waterway and natural soil have certain clean-up effect, More than the amount, water system, ground water regime, soil pollution and various problems can all be broken out.If taken no action to, it will cause by Carry out the environmental problem that can not be reversed.At present since the small-sized small septic tank in the country has cheap, non-maintaining, unregulated power spy Point is suitable for promoting the use of in rural households, is primarily present two kinds ofization excrement from processing method classification in the prior art Pond: Aerobic Process for Treatment and Anaerobic Treatment septic tank.Wherein, Aerobic Process for Treatment is present mainstream processing mode, is forced by aeration Microorganism is propagated to purify water, the advantages of septic tank is that high concentration BOD/COD can be reduced in relative short time.Disadvantage Excessive mud is generated, and needs to set up facility and excessive biological sludge is handled, overall cost is higher.Therefore it is unfavorable for Spread in China uses.
In contrast, Anaerobic Treatment is purified water using anaerobe or amphimicrobe.The processing side Formula can produce a small amount of excess sludge.Further, since not needing aerating system, energization power supply/electric power, therefore energy are not needed Enough greatly reduce investment and operating cost.Through retrieving, relevant application case has been disclosed in the prior art, such as Chinese patent Shen Please numbers 201320579090.5, authorized announcement date is that the application case on March 19th, 2014 discloses at a kind of domestic sewage in rural areas Reason system, the processing system include anaerobic treatment pool, mudpan and wet land treating system, and the anaerobic treatment pool is additionally provided with Plumbing for waste water road, top be equipped with biogas pipeline, including the sewage collector for collecting sewage, the sewage collector by into Dirty pipeline is connect with anaerobic treatment pool, and filtering coarse rack is equipped in the sewage collector, is provided in the anaerobic treatment pool For the blender of stirring-up sewage, the blender includes agitating shaft and paddle, drives blender, and blender can stir anaerobism Sewage in processing pond allows being deposited in oxygen processing pond sludge mixing and enter in sedimentation basin in sewage, and by sewage pipe, because Without forming accumulation, or even agglomeration in oxygen processing pond.Although the device of this application is directed to sludge and has carried out preferably Processing, however the apparatus structure of this application is complicated, cost of equipment maintenance is higher.
Chinese Patent Application No. 201521037912.2, authorized announcement date are that the application case on June 29th, 2016 discloses A kind of anaerobic sewage treatment equipment comprising housing bottom is equipped with outlet pipe, and the biological filter bed of material and filter bed are equipped in shell, described Filter bed is fixedly mounted inside housings, and the biological filter bed of material is arranged on filter bed, and cleaning dress is equipped in the biological filter bed of material It sets.Although the device structure of this application is simple, easy to use, cleaning device is still needed to the processing of biological sludge, And there are problems that insufficient cleaning, maintenance cost are higher for the solid sludges of accumulation using spraying-rinsing processing.
For another example Chinese Patent Application No. CN201720856726.4, the application case that authorized announcement date is on 2 13rd, 2018 Sludge anaerobic processing reaction unit is disclosed, which handles reaction unit openable chamber door when in use, sludge is put Enter in fermenting case, and feces of livestock and poultry and anaerobic reaction catalyst be put into seasoning spreading box, open seasoning spreading box by feces of livestock and poultry and Anaerobic reaction catalyst is put into fermenting case, and opens air blower, and reactant fine crushing is dispelled, and opens simultaneously motor, band Dynamic crawler belt and stirring blade stir sludge, can efficiently promote the anaerobic reaction of sludge, generate the combustible gases such as biogas, finally open The valve of escape pipe, biogas is loaded.Sludge anaerobic processing reaction unit can rapidly mix reactant with sludge It stirs evenly, makes the Anaerobic Treatment fully reacting of sludge, and Anaerobic Treatment is high-efficient.Although the device of this application handles effect Rate is high, but still needs the power facility of motor and stirring, higher cost, and is not handled preferably sludge, because This is in rural area using there is also certain defects.
Therefore, it based on the defect of the prior art, in conjunction with the characteristics of domestic sewage in rural areas, needs to invent a kind of structure simply square Just, motorless rural households' sewage-treatment plant.
Summary of the invention
