Embodiment approach 1（

[0059] Embodiment 1 (in the case of a single load-bearing frame):

[0060] The structure of a submerged lifting circulation type biological biofilm filter involved in the present invention is as follows: Figure 1~4 As shown, it is mainly composed of biological filter 1, two groups of filter curtains 2A and 2B of equal weight, bearing frame 3, lifting mechanism 4, anti-swing guide rail group 5 and pulley block 9, etc. The biological filter 1 is a plurality of sets of rectangular containers located on or below the ground; the load-bearing frame 3 spans the top of the biological filter 1 and coincides with the center of gravity plane of the filter curtains 2A and 2B, and the load-bearing frame 3 is fixedly connected to the ground or the biological filter 1; the pulley block 9 is suspended below the crossbeam of the load-bearing frame, respectively on both sides; the lifting mechanism 4 is installed in the middle position above the load-bearing frame crossbeam, and the two ends o...

Embodiment approach 2（

[0068] Embodiment 2 (in the case of multiple load-bearing frames):

[0069] The large-scale biofilter that the present invention relates to needs to adopt multi-bearing frame, and its structure is as follows Figure 18 As shown, its main structure is consistent with that of a single load-bearing frame biological filter, except that a plurality of load-bearing frames 3B, ... 3X are added in the length direction of the biological filter 1, and the added load-bearing frames 3B, ... 3X are connected with the middle load-bearing frame 3A The center is symmetrically distributed, and each load-bearing frame 3A, 3B, ... 3X is connected with the lifting lugs on the hanging beam 201 of the filter curtain 2A, 2B by a pull rope, and jointly bears the weight of the filter curtain 2A, 2B, so that the two sets of filter curtains The curtain is pulled up by the pull rope and suspended horizontally above the two sides of the biological filter. Driven by the driving mechanism, the two sets of f...

Abstract

The invention discloses a processing technology and device for an immersing lifting circulation type biofilm filter tank. Two groups of staggeredly arranged filter curtains are adopted, the two groupof filer curtains perform periodically back-and-forth lifting and lowering in the biofilm filter tank, so that biofilms on the two groups of the filter curtains are in contact with the atmosphere andsewage water one by one, organic substances in the sewage water are absorbed when the filter curtains are immersed downwards, and oxygen is absorbed when the filter curtains are lifted upwards and exposed in the atmosphere, the oxygen is brought into the sewage water when the filer curtains are immersed downwards again to cause the turbulence of the sewage water in a water tank, and therefore thedissolved oxygen is uniformly distributed to purify the sewage water. The device for the immersing lifting circulation type biofilm filter tank comprises the biological filter tank, a load bearing frame, two groups of the filter curtains, the lifting mechanism, a pulley group, and two groups of swing resisting guiding rails. The device is simple in structure, easy to manufacture, low in cost and high in sewage water treating efficiency.

Description

technical field [0001] The invention belongs to the technical field of environmental protection sewage treatment, and in particular relates to a treatment process and device for a submerged lift circulation biofilm filter. Background technique [0002] The existing biological turntable, as a fixed biofilm treatment device, has the following obvious disadvantages: [0003] 1. The shaft length is limited, and the cost of the long shaft is high: [0004] The cost of processing the long shaft is high, and the strength of the long shaft is also limited, so the shaft length of most biological turntables is less than 8 meters. The length of the shaft limits the number of blades that can be installed on the biological turntable, thus limiting the processing capacity of the biological turntable. , also seriously affects the cost of the biological turntable; [0005] 2. The disc diameter is limited: [0006] Theoretically, it is hoped that the specific surface area of ​​the disc sh...
