One of technology of power, is widely used always, and up-flow anaerobic biofilter (AF) is in traditional anaerobic activated sludge method
On the basis of grow up, in recent years and more applied in Practical Project, particularly medium and small project.Up-flow anaerobism is given birth to
Thing filter tank, water enters from reactor bottom, and after bottom of pond water distribution system is evenly arranged, waste water passes sequentially through the sludge blanket of suspension
With the biological filter bed of material, organic matter is contacted with the microorganism on sludge and biomembrane, fixed, is then resolved, water is again from pond face
Water outlet water charging system is uniformly discharged, into next level processor.
Experience have shown that, under identical condition of water quality and hydraulic detention time, the C0Dcr of up-flow anaerobic biofilter is gone
Except rate is higher than down-flow anaerobic filter, it is confirmed as the anaerobic organism in high-rate anaerobic reactor, therefore practice
Using up-flow anaerobic biofilter more in the filter tank.
In anaerobic biofilter there is very big difference in biosolids concentration with the difference of packed height.Up-flow anaerobism
The biosolids concentration of biofilter bottom is sometimes tens times of its top biosolids concentration, and bottom part easily occurs and filled out
Water stream channel blocking, current short circuit phenomenon, influence treatment effeciency between material.
In addition, the normal operation of anaerobic biofilter processing system depends on the relative equilibrium of production acid and methane phase speed,
Organic loading is too high, then acid production rate is possible to more than methane phase with sour rate, so as to cause under the accumulation of volatile acid makes pH rapid
Drop, hinders being normally carried out for methane phase stage, can cause " to be acidified " when serious.Because the capacity of whole processing system is limited
, the water inlet of reactor need to be controlled strictly, otherwise will greatly prolong the startup time.Therefore up-flow anaerobic biofilter is entered
It is imperative that water outlet is detected and controlled.
