Abstract
The utility model discloses a two-phase type aerobic granular sludge reactor, which comprises a reactor assembly, wherein the reactor assembly comprises an aeration tank and a primary settling device and is connected with a water inlet hole, a sludge backflow inlet, a water outlet and an aeration device, a sedimentation tank is connected with a water inlet, a water outlet and a sludge outlet, and the sludge outlet is also connected to the aeration tank. After the two-phase type aerobic granular sludge reactor adopts the technical scheme, aerobic granular sludge can be continuously cultured, in addition, the water outlet quality is good and stable, and good technical effects are realized.
Description
Technical field
The utility model relates to a kind of two-phase formula aerobic granular sludge reactor, is used to handle trade effluent.
Background technology
Along with the discovery of anaerobic grain, people are to its prilling mechanism and The Characteristic Study, and anaerobic grain is applied in the water treatment, and these have also caused the concern of people to aerobic grain.
Aerobic particle mud has characteristics such as microorganism concn height, capacity of resisting impact load is strong, settling velocity is fast, moisture percentage in sewage sludge is low, microbial population is many; In biological treatment process, use aerobic particle mud and can significantly reduce reactor volume, reduce excess sludge production, alleviate advantage such as treatment system load.And the waste water that aerobic particle mud is handled can directly reach emission standard, and particularly denitrogenation dephosphorizing is respond well, thereby aerobic particle mud becomes the research focus in the WWT.
Since (1997) such as Morgenroth after culture successful has gone out aerobic particle mud in sequence batch ((Sequencing Batch Reactor SBR), the operational mode of SBR is widely used for cultivating aerobic particle mud always.But the training method of SBR is not the prerequisite of granular sludge and steady running, the training method of the SBR that generally adopts at present and the harshness requirement of structure of reactor and operational conditions limited on the contrary to a certain extent the application of aerobic particle mud.
The utility model content
The utility model provides a kind of two-phase formula aerobic granular sludge reactor to the shortcoming of prior art, and this reactor drum can not only be cultivated aerobic particle mud in continous way ground, and effluent quality is good, and is stable again.
It is following that the utility model solves the problems of the technologies described above the technical scheme of being taked:
A kind of two-phase formula aerobic granular sludge reactor; Comprise reactor assemblies, said reactor assemblies comprises aeration tank and first sink device, wherein; Said reactor assemblies is connected with a prosopyle, a mud reflux inlet, a water outlet, and is connected with an aerating apparatus; Wherein, settling tank is connected with a water-in, a water outlet, a sludge outlet, and this sludge outlet is also connected to said aeration tank.
Further, preferred construction is that the connection portion is provided with a plurality of apertures between said sink device just and the aeration tank.
Further, preferred construction is to be provided with at least one power-driven pump between said reactor assemblies and the settling tank.
The utility model has been taked after the technique scheme, can not only cultivate aerobic particle mud in continous way ground, and effluent quality is good, and is stable again, has good technical effect.

Embodiment
Below in conjunction with accompanying drawing 1 ~ 2 and specific embodiment the utility model is carried out detailed description.
Wherein, two-phase formula aerobic granular sludge reactor comprises reactor assemblies; Said reactor assemblies comprises aeration tank and first sink device; Wherein, said reactor assemblies is connected with a prosopyle, a mud reflux inlet, a water outlet, and is connected with an aerating apparatus; Wherein, the settling tank top is connected with a water-in (being the water outlet of reactor assemblies), a water outlet, a sludge treatment outlet, and this sludge treatment outlet is also connected to said aeration tank.Wherein a part of activity sludge reflux is to the aeration tank, and another part mud is handled as excess sludge.
And the connection portion is provided with a plurality of apertures between said sink device just and the aeration tank, and part mud is back to the aeration tank in the first sink device.
Further, preferred construction is to be provided with at least one power-driven pump between said reactor assemblies and the settling tank.
Wherein, the correlation parameter of reactor assemblies in this device: the pitch angle is 45 °; Flow velocity 1m/s; Aspect ratio is 8:1; Perforate is than 75%.
The utility model has been taked after the technique scheme, can not only cultivate aerobic particle mud in continous way ground, and effluent quality is good, and is stable again, has good technical effect.
It should be noted that; Above-mentioned specific embodiment only is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection domain of the utility model.
