Description

A kind of anaerobic reactor
Technical field
The utility model provides a kind of anaerobic reactor, is used for the biological treatment of organic wastewater with high concentration, belongs to the wastewater treatment equipment technical field.
Background technology
The shortcoming of conventional anaerobic reactor is that the processing load is lower, floor space is bigger, causes sludge loss easily.In addition, traditional anaerobic reactor water inlet distribution system and return of waste water system design imperfection, the device acidifying that induces reaction easily, influence is operation normally.
Summary of the invention
The purpose of this utility model provides the anaerobic reactor that a kind of floor space is few, energy consumption is low, processing efficiency is high and easy to operate.
In order to achieve the above object, the technical solution of the utility model provides a kind of anaerobic reactor, comprise the reactor tank body, it is characterized in that, the roof of described reactor tank body is provided with methane outlet, the top of reactor tank body is provided with triphase separator, triphase separator top is provided with overflow weir, the middle part is provided with the compressed air rinsing pipe, the bottom is provided with sludge outlet, overflow weir is connected at the water outlet on the reactor tank body sidewall, the triphase separator below is provided with the recirculated water collection tube, the recirculated water collection tube is connected at the water inlet manifold of reactor tank body bottom, and water inlet manifold connects backwash tube by the water inlet distribution piping.
Further, described reactor tank body sidewall is provided with stopple coupon.
The utility model has the advantages that:
(1), the floor plan floor space is little: volumetric loading height, and make anaerobic reactor floor space of the present utility model little to the tower structure of high-altitude development;
(2), capacity of resisting impact load is strong: industrial production must cause the big ups and downs of waste water on water quality and quantity, anaerobic reactor of the present utility model can be the waste water in the reactor and the thorough mixing of intaking by circulation line well, thereby strengthens its capacity of resisting impact load.
(3) project construction is fast, the biological startup soon: anaerobic reactor of the present utility model can processing in the foundation of civil work construction.The building time of project has been saved in this work same period widely.In addition, the quick bio of anaerobic reactor of the present utility model starts needed anaerobic grain bacterial classification, can obtain from building up the project, thereby can shorten biological start time greatly.
(4) maintenance cost is few, long service life: anaerobic reactor of the present utility model, inner no-rotary part, fill out (filter) that also do not need to change expects, adopt high-quality engineering plastics simultaneously, thoroughly avoid etching problem, make that the work-ing life of anaerobic reactor of the present utility model can be very long.
(5) applied widely: the anaerobic grain sludge operation can be adopted, the operation of anaerobism floc sludge can be adopted again, therefore applied widely, suitable equally to water inlet suspended substance organic wastewater with high concentration higher, that the water inlet specific conductivity is high.
Description of drawings
Fig. 1 is a kind of structural representation of anaerobic reactor;
Fig. 2 is anaerobic reactor water inlet distribution piping synoptic diagram.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, be a kind of structural representation of anaerobic reactor, described anaerobic reactor is made up of water inlet manifold 1, water inlet distribution piping 2, reactor tank body 3, triphase separator 4, water outlet 5, methane outlet 6, nitrogen wash pipe 7, recirculated water collection tube 8, stopple coupon 9, overflow weir 10 and backwash tube 11.
Wherein, the roof of described reactor tank body 3 is provided with methane outlet 6, the top of reactor tank body 3 is provided with triphase separator 4, triphase separator 4 tops are provided with that overflow weir 10, middle part are provided with nitrogen wash pipe 7, the bottom is provided with sludge outlet, overflow weir 10 is connected at the water outlet 5 on reactor tank body 3 sidewalls, triphase separator 4 belows are provided with recirculated water collection tube 8, recirculated water collection tube 8 is connected at the water inlet manifold 1 of reactor tank body 3 bottoms, and water inlet manifold 1 connects backwash tube 11 by water inlet distribution piping 2.Described reactor tank body 3 sidewalls are provided with stopple coupon 9.
As shown in Figure 2, be the water inlet distribution piping synoptic diagram of anaerobic reactor, water inlet distribution piping 2 is horizontally placed on the bottom of anaerobic reactor, and an end connects water inlet manifold 1, and the other end connects backwash tube 11.The water source of backwash tube 11 can adopt fire water.For guaranteeing the homogeneity of water distribution system, waste water is at one end distributed to a plurality of arms by house steward and is flowed into, and each arm carries out water distribution by a plurality of water distributing pipes along specific direction, guarantees the waste water even water distribution, thereby avoids the organism localized accumulated; The other end at every water distributing pipe is reserved flushing pipe, adopts high pressure water or pressurized air to carry out back flushing during in order to line clogging.
During work, triphase separator 4 is divided into two parts of degas zone and settling region, in degas zone, biogas is removed and enters follow-up marsh gas treating system, mud separates with waste water in the settling region, and mud is deposited in the reactor, and waste water is after treatment discharged by overflow weir 10 simultaneously.In the lower end of triphase separator 4, the recirculated water collection tube 8 even waste water of collecting are installed are back to the water-in front end by recycle pump; Triphase separator is installed compressed air rinsing pipe 7, to guarantee to stop up triphase separator settling region mud discharging mouth.Waste water is sent by pumping to into water distribution piping, makes the water uniformly distributing in reactor, with the anaerobic sludge thorough mixing in the reactor.In reactor, waste water reacts by anaerobe, makes pollutants in waste water obtain removing.Then, waste water mixture enters triphase separator, and gas-liquid is separated admittedly, last overflow water outlet.
Adopt anaerobic reactor of the present utility model to carry out technological process for the treatment of papermaking, its water inlet COD concentration is about 8000mg/l, and effluent COD concentration is about 1600mg/l, and clearance can reach more than 80%, and the granule sludge growth better, and produced certain economic benefits.
