[0071] like figure 1 As shown, the present application provides a filler 100, the filler 100 has oxygen permeability and liquid resistance, the filler 100 includes an inner wall 110 and an outer wall 120 opposite to the inner wall 110, the inner wall 110 of the filler 100 surrounds A first flow space 130 is formed, and a second flow space 140 is provided outside the outer wall 120 of the filler 100. The first flow space 130 is used for the flow of one of the air and the water body to be treated to pass through, and the second flow space 140 The flow space 140 is used for the flow of the other of air and the body of water to be treated to pass through.

[0072] When the water body flows through the first flow space 130 and the air flows through the second flow space 140, the inner wall 110 of the filler 100 can support the growth of biofilm, and the oxygen molecules in the air flowing through the second flow space 140 can Enter the packing 100 through the outer wall 120 of the packing 100 to dissolve and diffuse, then diffuse to the inner wall 110 of the packing 100, and then desorb from the inner wall 110 of the packing 100 and enter the first flow space 130 to provide growth and metabolism for the biofilm Oxygen required for the biofilm to biodegrade the aerobic pollutants in the water flowing through the first overflow space 130 .

[0073] When the water body flows through the second flow space 140 and the air flows through the first flow space 130, the outer wall 120 of the filler 100 can support the growth of biofilm, and the oxygen molecules in the air flowing through the first flow space 130 can Through the inner wall 110 of the packing 100, it enters the inside of the packing 100 to dissolve and diffuse, then diffuses to the outer wall 120 of the packing 100, and then desorbs from the outer wall 120 of the packing 100 and enters the second flow space 140 to provide growth and metabolism for the biofilm. Oxygen required for the biofilm to biodegrade the aerobic pollutants in the water flowing through the second flow space 140 .

[0074]Specifically, the oxygen permeability of the filler 100 means that the inner sidewall 110 or the outer sidewall 120 of the filler 100 contacts the air and absorbs oxygen molecules in the air. The side where the inner wall 110 is located or the first flow space 130 of the packing 100, and the outside of the packing 100 is the opposite side where the outer wall 120 of the packing 100 is located or the second flow space 140 of the packing 100). Driven by the gradient, the oxygen molecules in the air adsorbed by one of the inner sidewall 110 and the outer sidewall 120 of the filler 100 dissolve and diffuse inside the filler 100, and then diffuse to the other side of the inner sidewall 110 and the outer sidewall 120 of the filler 100. One, and then desorb from the other of the inner side wall 110 and the outer side wall 120 of the packing 100 and enter the water body and biofilm in contact with the other of the inner side wall 110 and the outer side wall 120 of the packing 100, thereby realizing Oxygen molecules in the air enter the second flow space 140 of the packing 100 from the first flow space 130 of the packing 100 , or enter the first flow space 130 of the packing 100 from the second flow space 140 of the packing 100 .

[0075] The liquid resistance of the packing 100 means that water cannot pass through the inner wall 110 and the outer wall 120 of the packing 100 in liquid form, thereby preventing water from entering the second flow space 130 of the packing 100 from the first flow space 130 of the packing 100 140, or enter the first flow space 130 of the packing 100 from the second flow space 140 of the packing 100.

[0076] The filler 100 provided by this application has oxygen permeability and liquid resistance. When the water body flows through the first flow space 130 and the air flows through the second flow space 140, the inner wall 110 of the filler 100 can allow biofilm to attach and grow. , the oxygen molecules in the air flowing through the second flow space 140 can enter the inside of the packing 100 to dissolve and diffuse through the outer wall 120 of the packing 100, and then diffuse to the inner wall 110 of the packing 100, and then desorb from the inner wall 110 of the packing 100. Attached to the first flow space 130 to provide the biofilm with the oxygen needed for growth and metabolism, so that the biofilm can biodegrade the oxygen-consuming pollutants in the water flowing through the first flow space 130, thereby effectively removing the water body The effect of pollutants such as ammonia nitrogen and organic matter in the water; when the water body flows through the second flow space 140 and the air flows through the first flow space 130, the outer wall 120 of the packing 100 can support the growth of biofilm, and flow through the first flow space 130. Oxygen molecules in the air in the overflow space 130 can pass through the inner side wall 110 of the packing 100 into the inside of the packing 100 for dissolution and diffusion, then diffuse to the outer side wall 120 of the packing 100, and then desorb from the outer side wall 120 of the packing 100 and enter the second The overflow space 140 provides the biofilm with the oxygen required for growth and metabolism, so that the biofilm can biodegrade the oxygen-consuming pollutants in the water flowing through the second overflow space 140, thereby effectively removing ammonia nitrogen and organic matter in the water. The role of other pollutants;

[0077] Compared with the traditional aeration method, the filler 100 in this application has oxygen permeability and liquid resistance, when the water body flows through the first flow space 130 and the second flow space 140 where the biofilm is located, One of them, and when the air flows through the other of the first flow space 130 and the second flow space 140, the oxygen-consuming pollutants in the water flow from the outside of the biofilm (the side of the biofilm away from the packing 100) toward the biofilm. The inner side of the film (the side where the biofilm is attached to the filler 100) diffuses, and the oxygen molecules in the air enter the filler 100 through one of the inner sidewall 110 and the outer sidewall 120 of the filler 100 to dissolve and diffuse, and then diffuse to the filler The other of the inner side wall 110 and the outer side wall 120 of the packing 100 is then desorbed from the other of the inner side wall 110 and the outer side wall 120 of the packing 100 and enters into the other of the inner side wall 110 and the outer side wall 120 of the packing 100 In the contacted water body and biofilm, and spread from the inside of the biofilm (the side where the biofilm is attached to the filler 100) to the outside of the biofilm (the side where the biofilm is away from the filler 100), because the biofilm is close to the filler 100 Therefore, the distance for oxygen molecules to desorb from the inner wall 110 or outer wall 120 of the filler 100 and diffuse into the biofilm is short, and the mass transfer efficiency is high; at the same time, as the biofilm consumes oxygen molecules, On the inner and outer sides of the packing 100 (the inner side of the packing 100 is the side where the inner side wall 110 of the packing 100 is located or the first flow space 130 of the packing 100, and the outer side of the packing 100 is the opposite side where the outer side wall 120 of the packing 100 is located. Driven by the oxygen concentration gradient on the other side of the packing 100 or the second overflow space 140 of the packing 100), the oxygen molecules in the air located on one of the inner side and the outer side of the packing 100 continuously permeate the inner side wall of the packing 100 110 and the outer wall 120 supply oxygen molecules to the other biofilm located on the inside and outside of the packing 100. Therefore, the packing 100 in the present application can provide the biofilm with oxygen-consuming pollutants in the degraded water body sufficiently and rapidly. required oxygen molecules; at the same time, the space utilization rate of the first flow space 130 and the second flow space 140 of the filler 100 in the present application is high, the floor area is small, and it has the advantages of simple structure, easy implementation, and high biochemical treatment efficiency Advantages, and does not require traditional aeration equipment, saving energy consumption.

Therefore, the filler 300 in the present application can fully and quickly provide the biofilm with the oxygen molecules needed to degrade the oxygen-consuming pollutants in the water body; at the same time, the first flow space 330 and the second flow space of the filler 300 in the present application The 340 has a high space utilization rate, a small footprint, a simple structure, easy implementation, and high biochemical treatment efficiency, and does not require traditional aeration equipment, saving energy consumption.
