US 2020/0369543 A1 · TREATMENT PROCESS AND DEVICE FOR SUBMERGED LIFTING CIRCULATION TYPE BIO-MEMBRANE FILTER

Abstract

The present invention discloses a treatment process for a submerged lifting circulation type bio-membrane filter, wherein the treatment process comprises the following steps: two groups of symmetrically staggered filter curtains (2A and 2B) are adopted; the two groups of filter curtains (2A and 2B) are periodically lifted up and down in a reciprocating manner in a biofilter (1) under the action of a lifting mechanism (4), so that bio-membranes on the two groups of filter curtains (2A and 2B) are in contact with the atmosphere and sewage in turns, absorb organic matters in the sewage when lifting down for submerging, absorb oxygen when lifting up and exposing into to the atmosphere, and bring oxygen into the sewage and cause sewage turbulence in a water tank when lifting down for submerging again, so that the dissolved oxygen is uniformly distributed, thereby purifying the sewage.

A treatment process for a submerged lifting circulation type bio-membrane filter, comprising the following steps:

two groups of symmetrically staggered filter curtains with equal weight are adopted;
the two groups of filter curtains are periodically lifted up and down in a reciprocating manner in a biofilter under the action of a lifting mechanism, so that bio-membranes on the two groups of filter curtains are in contact with the atmosphere and sewage in turns, absorb organic matters in the sewage when lifting down for submerging, absorb oxygen when lifting up and exposing into the atmosphere, and bring oxygen into the sewage and cause sewage turbulence in a water tank when lifting down for submerging again, so that the dissolved oxygen is uniformly distributed, thereby purifying the sewage.

A device for the submerged lifting circulation bio-membrane filter, comprising a biofilter, a bearing frame, two groups of filter curtains with equal weight, a lifting mechanism, a pulley block and two groups of anti-swing guide rails, wherein the lifting mechanism is mounted at a middle position above a crossbeam of the bearing frame;

the bearing frame crosses over the biofilter and is fixed on the ground or a biofilter body;
the pulley block is suspended on the crossbeam of the bearing frame;
the lifting mechanism is connected with the two groups of filter curtains and drives the two groups of filter curtains by the driving mechanism in such a manner that a pull rope assembly passes through the pulley block;
and the two groups of anti-swing guide rails are respectively arranged at positions corresponding to the two ends of hanging beams of the two groups of filter curtains.
