Description
Technical field
The hydrolytic tank the present invention relates to technical field of sewage, especially a kind of multifunctional efficient are degraded.
Background technology
At present, China's rural population accounts for the 70% of total number of people, and about 9.1 hundred million people, the BOD for discharging in environment every year bears
Lotus total amount is about 13,300,000 tons (BOD loading amount is the 40g/ day for human beings), and severe contamination the water body in rural area.Domestic sewage in rural areas because
Disperse and be difficult to focus on, the current condition of the originally conveyance system of aquation is implemented according to China rural area, every peasant household implements
Tap water, it is necessary to install the anaerobic tank of corresponding water primary treatment, these simple devices, can be with as a result of biological method
Sanitary sewage is fermented and has been hydrolyzed, but still there are some defects in use in it：1st, in letters such as anaerobic tank
Easily in device, the degradation capability of anaerobic processes or limited, the sewage solids granule after process is more, concentration height, effluent quality
Discharging standards can not be reached, needs to carry out subsequent treatment, the subsequent treatment amount is big, pipe loadings are big, for pipe network is required
Height, required expense is more.2nd, after the easy device life-time service such as anaerobic tank, surface has scum silica frost, needs to carry out at set intervals
Clear cylinder is processed, therefore increased the manpower and material resources cost of later maintenance.If the 3, increase in the easy devices such as anaerobic tank exposed
Device of air, although degradation speed can be increased, quality of sewage disposal is improved, but aeration mode needs to use the energy, its energy consumption
Greatly, it is costly, China rural area can't be adapted to, the requirement of the economic development especially without electric mountain area or poverty-stricken area.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided one kind has self-cleaning function, it is possible to increase
Degradation speed, mitigation later stage pipe network load, and the multifunctional efficient degraded hydrolytic tank of financial burden will not be increased.
The present invention solves its technical problem and is achieved through the following technical solutions：
A kind of multifunctional efficient degraded hydrolytic tank, including cell body, inlet pipeline and outlet pipeline, a side wall peace of cell body
Water lines are put into, another side wall installs outlet pipeline, and the outlet of inlet pipeline and the import of outlet pipeline all extend to cell body
The lower section of internal liquid level, it is characterised in that：One vertical dividing plate is installed in cell body, the upper surface of the dividing plate is higher than in cell body
Portion's liquid level, has gap between the bottom surface of dividing plate and cell body bottom surface, in the cell body between dividing plate and outlet pipeline one is installed
Individual bacteria bed, the bacteria bed is located at the lower section of outlet pipeline import；Cover in spiral-lock one on the top board of cell body, lid on this
Inner chamber be connected with inside cell body, air intake duct is installed in side of lid on this, and the air inlet port of the air intake duct is located at

And, the water inlet end of described inlet pipeline is higher than the water side of outlet pipeline.
And, described dividing plate is positioned close to export pipeline side.
And, described bacteria bed is gasket packing filter bed, and gasket packing filter bed adopts protruded ripple plate, and this is board-like
The surface of filler filter bed has carried out wharf's pavement quality and has formed burr structure, is easy to biofilm.
And, described exhaust pipe is made up of horizontal tube and VERTICAL TUBE connection, and horizontal tube is inserted on lid, and water
The installation site of flat pipe is less than the inlet end of air intake duct, and VERTICAL TUBE is located at upper outer side of lid, by means of body of wall room is uprightly stretched to
Top, makes input and output gas pipe form pressure reduction, and air can be entered in groove by air inlet pipe, and the gas in groove is excluded through exhaustor,
Hydrolytic tank upper space could be formed with unpowered conditions, still oxygen area.
The advantages of the present invention are：
1st, this hydrolytic tank is completely different with anaerobic tank, and it is made up of anaerobic hydrolysis area, bacteria bed area and aerobic zone, energy
Enough allow different family domestic sewage normalization, the water miscible sewage of formation to be discharged, greatly reduce follow-up pipe network caliber
Require and biochemical treatment load, reduce investment and processing cost, be adapted to be widely popularized in rural area and use.
2nd, this hydrolytic tank can not only allow in family life and enter soil of hydrolytic tank etc and microorganism and can not degrade
Solidss here it is settlement separate, reduce the load of follow-up novel process device.Can also tentatively be located using anaerobe
Reason is degraded, and allows more pollutant to be transformed into the pollutant of solubility, is conducive to the degraded of follow-up novel process device.
Above-mentioned 2 points act on the regression nature that can realize sewage, the soil that water outlet can not degrade as far as possible without microorganism
Etc material, a kind of but water miscible sewage.Per all flows into novel process device with this sewage through pipeline, so
Requirement to pipeline just can lower, under the limited scope in many families, can be with water under PVC that the internal diameter of selection standard is 10 centimeters
Pipe, can greatly reduce pipeline expense and operating expenses.
3rd, this hydrolytic tank is covered in spiral-lock one on the top board of cell body, air intake duct is installed in the side of upper lid, another
Side is installed by exhaust pipe.Using principle of negative pressure make between cell body top board and liquid level formed an aerobic zone, aerobic zone it is micro-
Biological and metazoa being capable of scum silica frost that further fast decoupled is formed.Because scum silica frost can effectively be decomposed, therefore not
Clear groove work must again be exclusively carried out, it is possible to reduce the input of manpower and material resources.Additionally, this aerobic zone is to adopt principle of negative pressure
Formed, it is not necessary to by electric power equal energy source, therefore be adapted to used without electricity or Poor Mountainous Area, can really realize that energy-conservation subtracts
Row.
4th, aerobic zone is easy to aerobic microbiological and metazoal existence in this hydrolytic tank, realizes the removing of scum silica frost, and
And exhaustor also has the function of excluding abnormal flavour.
5th, the present invention is a kind of design science, multifunctional efficient rational in infrastructure, easy to use, energy-saving and emission-reduction degraded hydrolysis
Groove, using hydrolytic tank the degradation treatment effect of sewage can be strengthened, and simplify pipeline network construction, reduce cost input, and with from clearly
