At present, most of the treatment technologies used in the biodegradation treatment market are fixed biofilter beds. During the use of fixed biofilter beds, the old biofilm can not be discharged in time, resulting in pain points such as compaction, hardening, blockage and gully flow. The dynamic biological filter bed technology system adopts the dynamic treatment technology of biological filler, so that the contact position between biological filler and waste gas is always in a dynamic state, and the filler interface is constantly updated, which can solve the current industry pain points, improve the biodegradation effect, and finally improve the purification efficiency. The dynamic biological filter bed technology system includes two series of products: rotating biological filter bed and mobile biological filter bed, which can be applied to urban sewage lifting pump station, sewage treatment plant, garbage collection and treatment station, etc.
Applicable scenario: the processing capacity of a single set is less than 20000m3 / h
The collected waste gas enters the internal space from the upper inlet through the gas uniformly distributed cavity, passes through the biological packing along the radial direction, passes through the perforated pipe shaft, and is extracted from one end outlet through the fan.
In the process of entering the rotating biofilter, the waste gas is in full contact with the biofilm on the surface of the biofilter, and the polluting components in the waste gas are degraded by the biofilm, so as to achieve the purpose of deodorization.
During the rotation of the rotating biofilter bed, some biological fillers are immersed in water. With the rotation of the rotary table, the water on the disc will flow from the periphery to the center, evenly wet the disc not immersed in water, and make the disc surface evenly covered with biofilm, so as to improve the biodegradation effect of the system.
The biofilm on the biological filler will fall off due to thickening and aging. The fallen biofilm will fall off along the radial direction of the rotating biological filter bed from near the center to the outside, and fall into the water tank of the equipment box in the form of scattered sludge, which will be discharged into the box with the opening of the sludge discharge valve.
