Description

Efficient label lifting system

Technical Field

The invention relates to the field of water treatment and ecological environmental protection industry, in particular to water pollution prevention and advanced wastewater treatment, and particularly relates to an efficient label-extracting system.

Background

The aerobic activated sludge process is a relatively mature biological treatment technology, is widely applied to the current urban sewage treatment, and in the treatment of some high-concentration industrial wastewater, the anaerobic sewage and wastewater are also treated by the aerobic activated sludge process.

In the traditional sewage treatment process by an aerobic activated sludge method, the processes of dissolved oxygen aeration and biological oxidation are carried out simultaneously, but the dissolved oxygen aeration and the biological oxidation are separated in different tank bodies, and in order to ensure a certain sludge concentration, large-flow backflow must be carried out, so that the settled sludge in a secondary sedimentation tank flows back to an aeration tank through power to participate in the biological reaction process again.

For example, chinese patent publication No. CN202849149U discloses a micro-power domestic sewage treatment apparatus, which comprises an integrally sealed tank body, wherein the tank body is separated into an anaerobic tank, an anoxic tank, an aerobic tank, a sludge recirculation well and a sedimentation tank by a first partition plate, a second partition plate, a third partition plate and a fourth partition plate, the tops of the anaerobic tank, the anoxic tank, the aerobic tank, the sludge recirculation well and the sedimentation tank are respectively provided with a manhole, the anaerobic tank, the anoxic tank and the aerobic tank are all provided with a combined filler, and the front end of the anaerobic tank is provided with a water inlet. The structure is simple, and the effective utilization rate of the integrated equipment is improved; the fluidity of the sewage and the retention time in the tank body can be improved; the mud-water contact enhancement treatment effect can be promoted; and the mud-water separation effect can be enhanced. In the process, the activated sludge can continuously and circularly flow between the aerobic tank and the sedimentation tank, so that on one hand, a large amount of energy is consumed, and on the other hand, the biological activity of the activated sludge is reduced due to the continuous change of the growth environment of microorganisms, and the activated sludge is not beneficial to the implementation of biodegradation reaction.

Thus, devices related to loop oxidation, for example, chinese patent publication No. CN102815784B, discloses an aerobic three-phase separator.

However, this apparatus does not utilize space efficiently, and the effect of the circular flow oxidation is desired to be improved. Therefore, there is a need for improvements in the prior art.

The lower surface of the second opening 112 may be obliquely disposed in such a manner that a position on the lower surface of the second opening 112 relatively closer to the second barrier 120 has a higher horizontal height. The invention can at least realize the following beneficial technical effects by adopting the mode: first, the inclined arrangement of the upper surface of the second opening 112 facilitates the inflow of gas and activated sludge from the second opening 112; second, the inclined arrangement of the lower surface of the second opening 112 helps the activated sludge located thereon to more smoothly enter between the two first partition plates 110 under the combined action of the gravity component and the external pressure, and move upward by the air-lifting action of the air bubbles between the first partition plates 110.

According to a preferred embodiment, each first barrier 110 may be provided with at least one second barrier 120 disposed to intersect therewith.

According to a preferred embodiment, each first barrier 110 may be provided with at least two second barriers 120 intersecting therewith. At least two second partitions 120 intersecting each first partition 110 may be spaced apart in different horizontal height directions to allow the sewage with a portion of the activated sludge to flow around the corresponding second partitions 120 in different horizontal height directions to form a circular flow.

According to a preferred embodiment, at least two second barrier ribs 120 intersecting each first barrier rib 110 may have the same projection width when projected toward the horizontal projection plane. Alternatively, when projected toward the horizontal projection plane, a projected width of a second partition 120 located relatively above, among the at least two second partitions 120 intersecting each first partition 110, may be equal to a projected width of a second partition 120 located relatively below.

According to a preferred embodiment, at least two second barriers 120 intersecting each first barrier 110 may have different horizontal projection widths from each other when projected toward the horizontal projection plane, so that the activated sludge falling from the at least two second barriers 120 intersecting each first barrier 110 loses the support of the second barriers 120 at different plumb planes from each other and continues to fall. The invention can at least realize the following beneficial technical effects by adopting the mode: firstly, circulation of activated sludge can be formed on different spatial planes; second, a part of the activated sludge can be circulated more quickly.

For example, in a case where a horizontally projected width of a second partition 120 located relatively above, among at least two second partitions 120 intersecting each first partition 110, is greater than a horizontally projected width of a second partition 120 located relatively below, a first opening 111 corresponding to the second partition 120 located relatively above, among at least two second partitions 120 intersecting each first partition 110, may be larger than a first opening 111 corresponding to the second partition 120 located relatively below.

For example, in a case where a horizontally projected width of a second partition 120 located relatively above among at least two second partitions 120 intersecting each first partition 110 is greater than a horizontally projected width of a second partition 120 located relatively below, the second opening 112 corresponding to the second partition 120 located relatively above among at least two second partitions 120 intersecting each first partition 110 may be larger than the second opening 112 corresponding to the second partition 120 located relatively below. Preferably, the size of the second opening 112 may refer to the opening cross-sectional size of the second opening 112.

According to a preferred embodiment, the level of the upper edge of the second barrier 120 located relatively below, of the at least two second barriers 120 intersecting each first barrier 110, may be lower than the level of the lower edge of the second barrier 120 located relatively above.

Preferably, a distance in a direction of a plumb between an upper edge of the second partition plate 120 located relatively lower and a lower edge of the second partition plate 120 located relatively upper of the at least two second partition plates 120 intersecting each of the first partition plates 110 may be equal to 0.5 to 1.5 times a sum of plate lengths of the second partition plate 120 located relatively lower and the second partition plate 120 located relatively upper of the at least two second partition plates 120 intersecting each of the first partition plates 110. Preferably, the plate length of the single second barrier 120 may be a straight distance from an upper edge thereof to a lower edge thereof. The invention can at least realize the following beneficial technical effects by adopting the mode: firstly, the mutual interference of the circulation currents formed between the upper and lower two adjacent second partition plates 120 is reduced; second, if the scale is generated, the upper and lower two adjacent second partition plates 120 are not shielded from each other when the scale is cleaned, so that the cleaning is facilitated.

One end of each choke plate 300, which is away from the corresponding first partition 110, may be located below the other end of each choke plate 300, which intersects the corresponding first partition 110. Alternatively, one end of the corresponding choke plate 300 may be connected to the first separator 110. The other end of the respective choke plate 300 may extend flush with the lower edge of the corresponding first opening 111 or the other end of the respective choke plate 300 may extend below the lower edge of the corresponding first opening 111. Thereby reducing and/or preventing air bubbles within each pair of first partitions 110 from escaping through the first openings 111 and affecting the stripping effect within each pair of first partitions 110.

According to a preferred embodiment, the lower edge of each second partition 120 may extend downward to be flush with the lower edge of the corresponding second opening 112 or the lower edge of each second partition 120 may extend downward below the lower edge of the corresponding second opening 112. The invention can at least realize the following beneficial technical effects by adopting the mode: first, bubbles within each pair of first baffles 110 can be reduced and/or prevented from escaping through the second openings 112 to affect the stripping effect within each pair of first baffles 110; second, the lower edge of the second opening 112 is opened too deeply to affect the formation of the circular flow around the second barrier 120 and the speed of the circular flow, and therefore, the preferred embodiment can also contribute to the formation of the circular flow around the second barrier 120 and the securing of the speed of the circular flow around the second barrier 120, improving the oxygen transfer efficiency.

According to a preferred embodiment, the first acute included angle Q1 between the second partition 120 and the corresponding first partition 110 may be 30 ° to 80 °, particularly preferably 40 ° to 70 °, and most preferably 50 ° to 60 °.

According to a preferred embodiment, the second acute included angle Q2 between the choke plate 300 and the corresponding first separator 110 may be 30 ° to 80 °, particularly preferably 40 ° to 70 °, and most preferably 50 ° to 60 °. Preferably, the magnitude of second acute included angle Q2 is the same as the magnitude of first acute included angle Q1.

According to a preferred embodiment, an end of the second partition 120 remote from the corresponding first partition 110 may be provided with a guide dog-ear K1. The guide bent angle K1 may be provided such that one end of the second partition 120 is bent downward. The sum of the bending angle of the leading bending angle K1 plus the first acute included angle Q1 may be greater than 180 °. The invention can at least realize the following beneficial technical effects by adopting the mode: first, the preferred embodiment is such that even if there is a bend, the other end of the second partition plate 120 of the present invention is not hidden under the other part of the second partition plate 120, so that the activated sludge moving above the second partition plate 120 slides down more quickly due to the change of the inclination angle of the support surface after moving to the guide bevel K1 but does not directly fall down in the plumb direction, and the activated sludge located relatively rearward is guided, so that the activated sludge can slide down more quickly; secondly, the bent portion of the second partition plate 120 can also guide the air bubbles below the second partition plate 120, thereby reducing the possibility that the air bubbles flow out from the edge of the second partition plate 120.
