Problems solved by technology

The main problem existing in the existing upflow biological aerated filter is: when it runs for a certain period of time, the dirt trapped in the filter layer and the biofilm growing will increase the filtration resistance, and the biological aerated filter must be backwashed ; In order to solve this problem, some biological aerated filters with backwashing mechanism have appeared at present, but their structure is relatively complicated and the manufacturing cost is high; and its backwashing water consumption is large, wasting water resources

Abstract

The invention discloses an aerating biological filter pool in the water disposal device domain, which comprises the following parts: filter pool within aerating device and filtering device, water inlet pipe on the bottom of filter pool, backwash drainage pipe on the bottom of filter pool, pulse air-chamber to interconnect bottom of filter pool through backwash inlet pipe and vent pipe, wherein the vent pipe lies in one end of water sealing pipe in the pulse air-chamber; the other end of vent pipe connects gas-water separator, whose top possesses connection pipe with bottom interconnecting the bottom of pulse air-chamber through connection pipe.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to an aerated biological filter. Background technique [0002] At present, upward flow biological aerated filter is mostly used to treat sewage. The main problem existing in the existing upflow biological aerated filter is: when it runs for a certain period of time, the dirt trapped in the filter layer and the biofilm growing will increase the filtration resistance, and the biological aerated filter must be backwashed ; In order to solve this problem, some biological aerated filters with backwashing mechanism have appeared at present, but its structure is more complicated, and the manufacturing cost is high; and its backwashing water consumption is large, wasting water resources. Contents of the invention [0003] The present invention aims at the shortcomings existing in the prior art, and provides a technical solution with simple structure, low manufacturing cost, water saving and e...
