Technical field
The present invention relates to technical field of waste water processing, are related to a kind of design of the UASB reactor of filler fluidisation optimization.
Background technique
Upflow anaerobic sludge blanket reactor (UASB) is a kind of anaerobic organism method for handling sewage, is called and does up-flow
It is anaerobic mud bed.Traditional UASB structure mainly includes Sludge Bed, suspended sludge bed, gas reflecting plate, three phase separator, gas collection
Cover.The waterpower flow pattern of UASB is sufficiently mixed contact with the microorganism in Sludge Bed and suspended sludge bed and goes forward side by side at pulling flow type, water inlet
Row anaerobic digestion, the biogas that anaerobic digestion generates in the process holds up mud granule in uphill process, due to a large amount of bubbles
It generates, even if apparent agitaion also occurs for Sludge Bed under the conditions of lower organic and hydraulic loading, is settled in reactor
The poor wadding body shape sludge of performance then under the agitaion of gas, forms sludge suspension layer, settling property on reactor top
Preferable Granular sludge then forms the Sludge Bed of high concentration in reactor lower part, as the rising of water flow is flowed, gas and water, mud
Three-phase mixed liquor (digestive juice) rises in three phase separator, and gas is folded to collection chamber after encountering reflecting plate or baffle and effective
Separation discharge, sludge and water enters the settling zone on top, and muddy water separates under gravity.UASB is suitble to handle
The organic industrial sewage of high, middle concentration has many advantages, such as that sludge activity is high, hydraulic detention time is short, but it is there is also disadvantage,
Such as: sludge is easy to run off, sludge solid space is unevenly distributed, volumetric loading is relatively low, and reaction needs preference temperature etc..To avoid
Sludge loss in UASB reactor, at present it has been proposed that adding stuffing frame in the reactor, although reducing sludge loss, Gu
The shortcomings that fixed stuffing frame limits the fluidisation range of filler, is unevenly distributed there are still sludge solid space, therefore think to make to fill out
For material under the premise of not influencing granular mud bed stability, it is to solve problem above that fluidisation, which is got up, in reactor major part volume
Effective ways.
