Problems solved by technology

However, the disadvantage of the biological filter is that the filter bed is large in size and takes up a lot of land. During operation, clogging, gray flies and abnormal odors often occur.
The disadvantage of the biological turntable is that the material of the turntable is more expensive and the investment is large. In addition, because there is no ventilation equipment, the oxygen supply of the turntable depends on the biofilm on the surface of the turntable to contact the atmosphere.

Embodiment

[0020] This example describes an internal aeration hollow fiber biofilm carrier module and its application method. The internal aeration hollow fiber biofilm carrier module described in this embodiment includes a carrier element (1), an upper air distribution pipe (2), a lower air collecting pipe (3), a support pipe (4), and an air inlet (5) , purge port (6), drug washing connection port (7) and liquid medicine return port (8). The carrier element (1) is assembled from an arc-shaped fixing card (101), an air distribution cavity part (102), and a fiber module (103). The structure of the air distribution cavity part (102) is a T-shaped bracket, the bottom of which is a U-shaped open cavity, and there are several fixing bolt platforms on the outer edge of the bottom; its upper part is an arc-shaped fixing bracket, And the circular nozzle (102a) passes through the center of the upper arc-shaped fixing bracket and communicates with the U-shaped opening, and when assembled with the f...

Embodiment 2

[0024] This example describes another embodiment of the internal aeration hollow fiber biofilm carrier module and its application method. It includes a carrier element (1), an upper air distribution pipe (2), a lower air collecting pipe (3), a support pipe (4), an air inlet (5), a purge port (6), a chemical washing connection port (7) and Liquid medicine return port (8). The carrier element (1) is assembled from an arc-shaped fixing card (101), an air distribution cavity part (102), and a fiber module (103). Its air distribution chamber part (102) is constructed as a T-shaped Tito, with a U-shaped open cavity at its bottom ring-shaped part, and several fixing bolt platforms on the edge of the bottom ring-shaped part; its upper part is arc-shaped The card holder is fixed, and the circular nozzle (102a) passes through the center of the upper arc-shaped fixed card holder to communicate with the U-shaped opening. When assembled with the fiber module (103), an air distribution cav...

Embodiment 3

[0027]This embodiment describes an embodiment in which the internal aeration hollow fiber biofilm carrier modules are arranged in double rows to form a module unit. The realization of the technical solution is that the first step is to use two upper air distribution pipes (2) and 2 tees with the same diameter, 4 elbows and required pipe fittings to make a rectangular air distribution loop, and two on the rectangular air distribution loop. One of the tee ports is used as the air inlet (5) and the other is used as the liquid medicine return port (8); secondly, use two tees and 4 elbows of the same diameter as the two lower air collecting pipes (3) and all Pipe fittings are required, and made into a rectangular loop with the same size as the rectangular gas distribution loop. One of the two tee ports on the rectangular loop is used as the purge port (6) and the other is used as the chemical washing connection port (7); then, use The two support tubes (4) are respectively connecte...

Abstract

An inner-aeration hollow fiber film carrier module comprises carrier elements (1), an upper gas distribution tube (2), a lower gas collection tube (3), support tubes (4), a gas inlet (5), a blowing port (6), a drug washing connection port (7) and a drug solution backflow port (8). The inner-aeration hollow fiber film carrier module is characterized in that the gas inlet (5) and the drug solution backflow port (8) are positioned on two ends of the upper gas distribution tube (2) respectively; the blowing port (6) and the drug washing connection port (7) are positioned on two ends of the lower water collection tube (3) respectively; the two support tubes (4), the upper gas distribution tube (2) and the lower gas collection tube (3) form an assembled frame of the inner-aeration hollow fiber film carrier module; and the support tubes (4) are not communicated with the upper gas distribution tube (2) or the lower gas collection tube (3). In the invention, the inner-aeration hollow fiber film carrier elements are assembled into the module according to processing capability demands; a nitrification reaction and a denitrification reaction can be realized in a same biochemical reaction pool, and the specific surface area of a biological film module is large, so the occupied land of the biochemical pool is reduced; and the inner-aeration hollow fiber film carrier module is suitable for new biological film pools, and is also suitable for reconstructing present biological film pools in the practical application process. The inner-aeration hollow fiber film carrier module has an advantage that the novel inner-aeration hollow fiber film carrier elements provided in the invention are standardized and suitable for batch production.

Description

technical field [0001] The invention relates to a biofilm water treatment technology and equipment, belonging to the technical field of wastewater treatment. Background technique [0002] At present, biofilm wastewater treatment technology is mainly divided into two types of technology according to the contact mode of microorganisms and wastewater: biofilter and biological turntable. However, the disadvantage of the biological filter is that the filter bed has a large volume and occupies a lot of land, and blockage, dust fly and abnormal odor often occur during operation. The disadvantage of the biological turntable is that the material of the turntable is more expensive and the investment is large. In addition, because there is no ventilation equipment, the oxygen supply of the turntable depends on the biofilm on the surface of the turntable to contact the atmosphere. In this way, the volatile substances in the wastewater will cause pollution; moreover, the biological turnt...
