Description
Technical field
The utility model relates to a kind of water-distributing device of anaerobic reactor, belongs to the refuse leachate treatment technology field.
Background technology
When adopting the burning method treating refuse, usually can be through the maturing process of week age, to reduce the water ratio of rubbish, maturing process can produce a certain amount of percolate.The incineration plant percolate mainly has following characteristics: (1), organic kind is more and concentration is high, the vary within wide limits of concentration.The percolate of incineration plant is the percolate on the same day mostly, do not pass through tangible biochemical action, thereby contain a large amount of organism such as heterocyclic arene compound, alcohol compound and amino benzenes compounds, the COD value is usually between 40000mg/L-80000mg/L.(2), biodegradability can be better.The incineration plant percolate is wanted a little higher than early stage refuse landfill percolate, and the BOD/COD value is usually about 0.5.(3), ammonia-nitrogen content height.The ammonia nitrogen value is more than 1000mg/L.(4), metal content height.The garbage filter liquid processing method mainly comprises biological treatment, physico-chemical processes, land law and polytechnic combination etc., and biological process is the most frequently used a kind of method in the percolate processing, and upflow anaerobic sludge blanket process-filtering layer reactor has high processing efficient, operation energy consumption is low, surplus sludge volume is few, and remarkable advantages such as recyclable biogas, now progressively at organic waste water, particularly high concentrated organic wastewater is applied in handling.
Upflow anaerobic sludge blanket process-filtering layer reactor is formed by stacking by upflow sludge blanket and anaerobic filter, and its lower floor is a upflow sludge blanket, and the upper strata is an anaerobic filter, and the anaerobic filter bottom is fixed with filler, top is settling section and collecting methane district.When sewage flows from bottom to top, at first finish organic conversion by the anaerobion of Sludge Bed and suspension zone, make it to become methane, carbonic acid gas and water, in the water body uphill process through the packing area, mud in the water body obtains effectively catching in the packing area, further reduce the organic concentration in the water body by the microbial film on the filler, finished the three phase separation of gas, solid, liquid at last again by settling section.Present water-distributing device is the purpose that reaches water distribution uniformity, and a kind of employing shower nozzle is water distribution regularly, but percolate impurity is more, easily causes the obstruction of shower nozzle.Another kind is to have increased the Heng Yabushui device in cylindrical shell, this Heng Yabushui device is made of polycomponent pipe arrangement and closed reallocation water tank, the reallocation water tank is arranged on the bottom of distribution piping, and the water distribution head that is positioned at two water distributing pipes middle part by distributor box reaches the purpose of water distribution uniformity.But this kind structure is complex structure on the one hand, and it is big to take up room, and on the other hand because water distribution is to realize by the water distribution head that distributes water tank, because hydraulic pressure reduces, and reduces sewage surface upflow velocity, influences mixing of mud and percolate.
Summary of the invention
It is rational in infrastructure that the purpose of this utility model provides a kind of water distribution, and easy construction, water distribution branch pipe are difficult for stopping up, the water-distributing device of anaerobic reactor easily of removing contamination,
The utility model is that the technical scheme that achieves the above object is: a kind of water-distributing device of anaerobic reactor, comprise the water distribution person in charge and water distribution branch pipe, water distribution with water-in and flush-through connection is responsible for the periphery that is arranged on cylindrical shell, described water distribution branch pipe is the closed ring pipe, water distribution branch pipe more than four is along the same plane symmetry setting of cylindrical shell, passing the connecting branch of cylindrical shell more than four is responsible for to be connected with water distribution branch pipe with water distribution respectively and communicates, each water distribution branch pipe bottom surface is provided with the posticum more than three at least, and the posticum on each water distribution branch pipe is along the layout that interlaces of the concentric circumferences more than three.
The utility model adopts a plurality of closed ring pipes as water distribution branch pipe, because water distribution branch pipe is symmetricly set in the cylindrical shell, and the posticum on each water distribution branch pipe is along the layout that interlaces of waney concentric circumferences more than three, make the water outlet diffusion setting from inside to outside along the circumferential direction of each water distribution branch pipe, by increasing each posticum area coverage, improve the homogeneity of anaerobic reactor water distribution on the one hand.On the other hand, the water outlet hydraulic pressure of each water distribution branch pipe is consistent substantially, water distribution is reasonable, with the thorough mixing of strengthening water inlet and mud bed with contact, and avoided near reactor wall, forming short situation about flowing, downward in addition high velocity flow has been strengthened the turbulent state of sludge blanket, water inlet fully contacts with sludge blanket, so maximally utilise the mud in the reactor, improve the volume of equipment utilization ratio, improve decontamination effect improving.The utility model is provided with flush-through connection because water distribution is responsible for, and when water distribution branch pipe takes place to stop up, is easy to be eliminated by the dosing flushing, has thoroughly solved the susceptible to plugging problem of water-distributing device.The utility model adopts the closed ring pipe as water distribution branch pipe, simplifies the cloth water structure, owing to be connected with water distribution branch pipe with the water distribution person in charge by connecting branch, is convenient to construction.
