[0028] Reference Figure 1-5 The utility model provides a biofilm reactor sewage treatment mechanism, comprising:

[0029] The main unit 100 includes a housing 101. A plurality of mounting openings 102 are provided on one outer surface of the housing 101. A drain pipe 103 is fixedly connected to the lower portion of the outer surface of the other outer surface of the housing 101. A solenoid valve 104 is provided on the outer surface of the drain pipe 103.

[0030] The filtration unit 200 includes an aeration assembly 201, which is mounted on the upper inner wall of the housing 101. Below the aeration assembly 201 is an inclined plate settling assembly 202, and below this is a biofilm filtration assembly 203. Both the inclined plate settling assembly 202 and the biofilm filtration assembly 203 are installed within the housing 101 through the mounting port 102. The aeration assembly 201 injects oxygen into the wastewater, providing the necessary oxidizing environment to promote the growth of aerobic microorganisms and the decomposition of organic matter. The inclined plate settling assembly 202, through its inclined plate structure, increases the flow path and duration of the wastewater, allowing for better sedimentation of suspended solids and improving the efficiency of subsequent filtration. The biofilm filtration assembly 203 utilizes a biofilm attached to the filter material for deep biological treatment, removing more pollutants and degrading difficult-to-treat organic matter. The mounting port 102 of the housing 101 facilitates installation and maintenance of the components, while the solenoid valve 104 on the drain pipe 103 effectively controls the amount and timing of water discharge.

[0031] The aeration assembly 201 includes a sewage tank 201a, the outer surface of which is fixedly connected to the upper inner wall of the housing 101. An air pump 201b is fixedly connected to one side of the upper surface of the sewage tank 201a. An air pipe 201c is fixedly connected to the output end of the air pump 201b. Multiple exhaust headers 201d are fixedly connected to the upper surface of the air pipe 201c. A valve 201e is fixedly connected to one side of the inner wall of the sewage tank 201a. The air pipe 201c is fixedly connected to the interior of the sewage tank 201a. The air pump 201b, as the core component of the oxygen supply, delivers oxygen to the interior of the sewage tank 201a via the air pipe 201c. The exhaust headers 201d are evenly distributed along the air pipe, effectively diffusing oxygen throughout the sewage in the form of fine bubbles. This increases the contact area between gas and water, thereby improving the solubility and utilization rate of oxygen. The generation of these fine bubbles helps suspend and activate microorganisms in the sewage, enhancing their metabolic activity and accelerating the decomposition of organic matter.

[0032] Furthermore, the inclined plate sedimentation assembly 202 includes a first connecting plate 202a, one side of which is fixedly connected to an inclined plate 202b. The upper surface of the inclined plate 202b is fixedly connected to a sedimentation box 202e. A placement plate 202c is provided on both sides of the lower surface of the inclined plate 202b. The outer surface of one side of the placement plate 202c is fixedly connected to the inner wall of the housing 101, and one end of the placement plate 202c is fixedly connected to a limit block 202d. The placement plate 202c is tilted and arranged inside the housing 101. The lower surface of the inclined plate 202b is in contact with the upper surface of the placement plate 202c and the outer surface of the limit block 202d. The other side of the outer surface of the first connecting plate 202a is fixedly connected to a handle 204. The side surface of the first connecting plate 202a is in contact with the inner wall of the mounting port 102. This increases the efficiency of solid-liquid separation during the sedimentation process, thereby improving the overall effect of water treatment. The setting of the inclined plate 202b allows the solid particles in the flowing water to move downward along the inclined plate surface under the action of gravity, increasing the sedimentation area and accelerating the sedimentation of the particles. The sedimentation box 202e is used to collect the precipitated solid matter for easy processing and recycling. The inclined layout of the placement plate 202c optimizes the spatial configuration between the inclined plate 202b and the box body 101, making the entire assembly more compact and improving the structural stability. The limit block 202d ensures that the inclined plate 202b maintains an appropriate tilt angle during the sedimentation process to prevent it from shifting. The design of the handle 204 facilitates the installation and maintenance of the inclined plate sedimentation assembly 202, making the operation more convenient.

[0033] Furthermore, the biofilm filtration assembly 203 includes a second connecting plate 203a, a biofilm plate 203b fixedly connected to the upper portion of one side of the outer surface of the second connecting plate 203a, an activated carbon filter layer 203c fixedly connected to the lower portion of one side of the outer surface of the second connecting plate 203a, and mounting rails 203d are provided on both sides of the outer surface of the biofilm plate 203b and the activated carbon filter layer 203c. The outer surface of the mounting rails 203d is fixedly connected to the lower portion of the inner wall of the housing 101. A handle 204 is also fixedly connected to the other side of the outer surface of the second connecting plate 203a. The side surface of the second connecting plate 203a is in contact with the inner wall of the lower mounting port 102, and one end of the drain pipe 103 is disposed at the lower portion of the biofilm filtration assembly 203. The design of the biofilm filtration assembly 203 integrates both biofilm and activated carbon filtration technologies, effectively improving the purification capacity of the water treatment system. The biofilm on the biofilm plate 203b is a membranous biological layer composed of a variety of microorganisms. These microorganisms can degrade organic matter in the water, thereby achieving the effect of biological purification. The activated carbon filter layer 203c can adsorb residual organic compounds and some heavy metals in the water, further improving the water quality. In addition, the double-layer filtration design of the biofilm plate 203b and the activated carbon filter layer 203c makes the filtration more thorough. At the same time, this structure is also convenient for cleaning and replacing materials. The mounting track 203d provides stable installation support to ensure the stability of the component during operation. The design of the handle 204 makes the biofilm filtration component 203 easy to install and maintain, improving the user's convenience in operation.

[0034] During use, the sewage is first placed into the sewage pool 201a, and then the air pump 201b is started to discharge oxygen into the sewage through the air pipe 201c and the exhaust head 201d, so that the oxygen can be effectively diffused into the entire sewage in the form of small bubbles, and the impurities are condensed. The sewage is discharged into the upper surface of the inclined plate sedimentation component 202, and the pollutants are precipitated inside the sedimentation box 202e by reducing the flow rate. Then the sewage will flow into the interior of the biofilm filtration component 203. The biofilm on the biofilm plate 203b is a membrane-like biological layer composed of a variety of microorganisms. These microorganisms can degrade organic matter in the water, thereby achieving the effect of biological purification. The activated carbon filter layer 203c can adsorb the remaining organic compounds and some heavy metals in the water, further improving the water quality, thereby achieving an improved purification effect.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
