Description
Technical Field
The utility model relates to a wastewater treatment technology, in particular to a light filter material denitrification biological filter easy to overhaul.
Background
The conventional denitrification biofilter commonly used at present is mainly divided into a downward flow type and an upward flow type, and the filter material mostly adopts heavy submerged filter material. The traditional upflow denitrification biological filter distributes water from the bottom, the inlet water enters the filter through a water distribution system, then flows upwards through a denitrification area of a heavy filter material bed layer, and then flows out through a water outlet weir. The traditional downward flow type denitrification biological filter distributes water from the top, and the inlet water flows downwards through a denitrification area of a light filter material bed layer under the action of gravity and then flows out from the lower part of the filter.
The traditional upflow denitrification biological filter and downflow denitrification biological filter have the characteristics in operation respectively, and the difference is mainly shown in the following three aspects:
a. comparison of homogeneity from water distribution: the traditional downflow denitrification biological filter is widely applied because the requirement on water distribution is low and the loss of the resistance of the bed layer at each point is not easy to cause large difference; in the traditional upflow denitrification biofilter, after the filter material is blocked due to the aggregation of microorganisms, water flows upwards through the bed layer along hardened cracks of the filter material, so that water distribution is extremely uneven, and the denitrification efficiency is sharply reduced.
b. Comparison from the retained biomass: the downflow denitrification biological filter needs to overcome the resistance of a bed layer to meet the filtering requirement, the resistance loss inside the bed layer is related to the height of a water distribution head, the general height of water distribution is 1-2m, the corresponding light filter material bed layer space is compressed, the biomass contained inside the light filter material bed layer space is limited, and the microorganisms at the stripping part need to be backwashed regularly, so that the resistance of the bed layer is reduced, and the overflowing speed is increased.
c. Release from nitrogen comparison: the downflow denitrification biological filter usually adopts quartz sand with a small diameter as a filter material, and the direction of water flow is opposite to the release speed of nitrogen. There is a significant accumulation of nitrogen in the bed. Resulting in a significant increase in the reaction dead space and dead space of the system.
The traditional downflow denitrification biological filter has uniform water distribution, less biomass and poorer degassing effect; the traditional upflow denitrification filter has poor water distribution uniformity, more biomass and better degassing effect.
The two traditional denitrification biological filters have the characteristics respectively, but the sizes of part of the filters are adaptively designed according to the actual conditions on site so far, and the other part of the filters can select larger denitrification filter units to be matched in parallel. The design is carried out completely according to the field situation, the actual needs of a single project can be better matched, but the designed filter tank structure is not a standard product, so the speed of processing, mounting and application is slower. The simple and rough parallel connection of the large filter units is simple and convenient, but often exceeds or does not meet the actual requirements of a single project.
The backwashing aeration components of the traditional denitrification biofilter are all fixed at the bottom of the denitrification biofilter, so that the maintenance cost is very high, or the backwashing can not be maintained at all, the backwashing process is very important for the continuous and stable operation of the denitrification biofilter, and the traditional backwashing aeration system has a great defect.
