Hive type biological filtration reactor

Abstract

The invention discloses a hive type biological filtration reactor, which belongs to the field of waste gas treatment by a biological filtration method in the atmosphere pollution control engineering in the environment engineering. The reactor mainly consists of a tank cover, a secondary cover, a hive frame, an inner screen, a tank, a movable bottom plate, a hive door stop, a tank rack, an air inlet, a nutrient solution inlet, a nutrient solution distributor and an air outlet. Filtration packing is fixed on the frame consisting of an upper beam, a lower beam and side strips, the nutrient solution inlet and the nutrient solution distributor are disposed on the secondary cover, a residual nutrient solution guiding and draining hole is reserved at the bottom of the tank rack, the air inlet is arranged on the left side of the front of the tank rack, the air outlet is arranged on the right side of the secondary cover and penetrates through the tank cover, and a channel bringing convenience for small animals to move is arranged between the hive frame and the movable bottom plate. The hive type biological filtration reactor overcomes shortcomings that an existing structure of a gas-phase biofilter is not favorable for controlling excessive accumulation of biological films in packing of the gas-phase biofilter by a biological method, and has the advantages of simplicity and convenience in operation, economy and effectiveness.

Description

technical field [0001] The invention belongs to the field of waste gas treatment by biological filtration in air pollution control engineering in environmental engineering, and in particular relates to a beehive type biological filtration reactor. Background technique [0002] Gas-phase biological filtration technology can effectively control the emission of odor and organic waste gas. It uses the biofilm attached to the filter material to decompose and transform the pollutants in the waste gas into simple inorganic substances or cell components. It has low investment and operation costs and relatively high efficiency. Good, no secondary pollution and other advantages, so the application prospect is very broad. However, after long-term operation of gas-phase biofilter, excessive accumulation of biofilm in the filler often occurs. Excessive accumulation of biofilm will lead to many operational problems in the gas phase biofilter, such as bed blockage, short flow, increased p...
