A moving bed biological aerated filter

Abstract

The invention relates to the technical field of biological filters, in particular to a moving bed type biological aerated filter. The moving bed type biological aerated filter comprises a base, a support mechanism, a sliding seat, a storage mechanism, a lifting mechanism, a biological membrane mechanism and a locking mechanism. Growth grooves can be filled with microorganisms, the concave growth grooves can form areas allowing the microorganisms to grow, the condition that the microorganisms fall off or are washed away is avoided, the microorganisms can grow around an attachment rod, so that the space utilization rate of the growth grooves is increased, and the microorganisms are distributed more stereoscopically; rapid updating and use of the biological membrane mechanism can be realizedwithout overall dismounting, multiple biological membrane mechanisms can be combined for use according to treatment demands, and the functional structures of biological membranes are more diversified;the storage mechanism can be rapidly lifted through the lifting mechanism, a cover plate is dismounted, and the biological membrane mechanism is rapidly maintained without manual lifting.

Description

technical field [0001] The invention relates to the technical field of biological filters, in particular to a moving bed aerated biological filter. Background technique [0002] The biological aerated filter process has the functions of removing SS, COD, BOD, nitrification, nitrogen removal, phosphorus removal, and AOX (harmful substances); the biological aerated filter is a new process that integrates biological oxidation and interception of suspended solids. [0003] The current biofilter lacks a good growth area, which makes the microorganisms easy to fall and move, and cannot form a complete biofilm, which affects the growth effect of the microorganisms; the structure of the biofilm is relatively simple, and it is necessary to update the biofilm. Dismantling the overall membrane structure requires manual lifting, which is time-consuming and laborious. In view of this, the invention provides a moving bed biological aerated filter, which has the following characteristics:...
