[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-7 In this embodiment of the utility model, a modular and expandable integrated sewage treatment equipment includes a frame body 13, within which, from left to right, are arranged an equalization tank 4, a biofilm treatment tank 3, a reaction tank 2, a sedimentation tank 1, and a water collection tank 12.

[0032] A protective net 8 is fixed to one end of the frame 13, and a dosing tank 10 is installed inside the protective net 8; a metering pump 11 is installed above the dosing tank 10; the inlet of the metering pump 11 is connected to the dosing tank 10 through a pipe; and the outlet of the metering pump 11 extends into the reaction tank 2 through a pipe.

[0033] The biofilm treatment tank 3 is internally fixedly equipped with multiple sets of biofilm packing material 5.

[0034] By adopting the above technical solution, during use, the sewage is first discharged into the sedimentation tank 1 for sedimentation treatment. Then, the sedimented sewage enters the reaction tank 2 to react with chemical agents for further treatment. After the reaction is completed, the sewage enters the biofilm treatment tank 3 for biofilm treatment to improve water quality. Then, it enters the equalization tank 4 for pH adjustment, and then is pumped into the collection tank 12 for storage for the next step of water treatment.

[0035] In this embodiment, a horizontal plate is fixed to the top of the regulating tank 4, and an agitator 7 is installed on the horizontal plate; the blades of the agitator 7 extend to the bottom side inside the regulating tank 4.

[0036] By adopting the above technical solution, the wastewater is regulated by the equalization tank 4. The equalization tank uses a stirrer 7 to homogenize the wastewater composition and ensure the pH value of the water.

[0037] Furthermore, a booster pump 17 is installed inside the regulating tank 4, and the outlet end of the booster pump 17 is connected to the water collection tank 12 through a transmission pipe 18; a drain outlet is provided at the lower end of one side of the water collection tank 12.

[0038] The setup of the booster pump 17 and the transmission pipe 18 enables the regulated wastewater to be transported to the collection tank 12 for temporary storage, so that it can be used for subsequent process water.

[0039] As a further explanation of the above embodiments, water circulation can be carried out between the reaction tank 2 and the biofilm treatment tank 3, and between the biofilm treatment tank 3 and the equalization tank 4, by overflow or by pumping.

[0040] In this embodiment, a ladder 14 is fixed to one end of the frame 13 away from the protective net 8, and a maintenance platform 15 is provided at the upper end of the ladder 14; the maintenance platform 15 is horizontally placed on the top of the frame 13 and fixedly connected.

[0041] By adopting the above technical solution, the installation of ladder 14 and maintenance platform 15 facilitates the climbing of staff and makes it easier for subsequent cleaning, disinfection and maintenance of the sewage treatment device.

[0042] In this embodiment, multiple sets of biofilm packing materials 5 are arranged in a row, and each biofilm packing material 5 is provided with several filaments made of polypropylene.

[0043] By adopting the above technical solution, the polypropylene filaments on the biofilm packing 5 serve as a carrier for the attachment and growth of microorganisms. Their core function is to provide a huge attachment surface and habitat for microorganisms (such as bacteria, fungi, protozoa, etc.) to form a biofilm, thereby efficiently degrading pollutants in wastewater.

[0044] Biofilm packing material 5 can adsorb a large number of microorganisms to form a biofilm; the microorganisms in the biofilm adsorb and decompose organic matter (such as COD) in the wastewater. Pollutants such as nitrogen (ammonia nitrogen, total nitrogen) and phosphorus (total phosphorus) are purified.

[0045] In this embodiment, a partition plate 107 is fixed inside the sedimentation tank 1; the partition plate 107 divides the sedimentation tank into a sedimentation chamber 101 and an overflow chamber 105, and an overflow port 104 is provided on one side of the upper end of the partition plate 107.

[0046] More specifically, a rectangular frame is provided at the upper end of the sedimentation chamber 101, and a serrated baffle 102 is provided around the rectangular frame; an overflow channel 103 is formed between the serrated baffle 102 and the four walls of the sedimentation chamber 101.

[0047] An extraction pipe 106 is fixed to the outside of the overflow chamber 105; the extraction pipe 106 is connected to the inlet end of the sewage pump 16; and the outlet end of the sewage pump 16 is connected to the reaction tank 2 through a pipe.

[0048] By adopting the above technical solution, the sewage is settled in the sedimentation chamber 101, and a certain amount of flocculant is added. The sewage flocculates and settles in the sedimentation chamber 101. After passing through the sawtooth baffle 102, the sewage overflows into the overflow channel 103, and then enters the overflow chamber 105 through the overflow port 104. Under the pumping of the sewage pump 16, the sewage is transported to the reaction tank 2 for further treatment.

[0049] The dosing tank 10 stores microbial agents, which are added to the reaction tank 2 via the metering pump 11 to enhance specific functional bacterial groups (such as nitrifying bacteria, polyphosphate-accumulating bacteria, and bacteria that degrade recalcitrant organic matter), thereby improving the system's shock resistance or treatment efficiency. This also facilitates the biological treatment effect of the biofilm treatment tank 3.

[0050] Aerators 6 are installed on the bottom side inside the biofilm treatment tank 3 and the reaction tank 2; the aerators 6 are connected to the air compressor 19 through the aeration pipe; the air compressor 19 is installed inside the protective net 8.

[0051] The purpose of installing aerator 6 in reaction tank 2 is to agitate the water flow generated by aeration so that the added microbial agents (such as nitrifying bacteria, polyphosphate-accumulating bacteria, and compound functional bacteria) can be evenly diffused throughout the reaction tank, preventing the agents from settling at the bottom of the tank and ensuring that they are in full contact with pollutants in the wastewater (such as ammonia nitrogen, phosphorus, and recalcitrant organic matter), thereby improving the reaction efficiency.

[0052] The purpose of installing aerator 6 in biofilm treatment tank 3 is to oxygenate the water body through bubble diffusion or mechanical stirring, so that the dissolved oxygen (DO) in the water layer on the surface of the biofilm is maintained at 2-4 mg / L (depending on the process), ensuring that the respiration and oxidative decomposition reaction of aerobic bacteria proceed normally.

[0053] The water flow disturbance generated by aeration can accelerate the diffusion of pollutants (such as organic matter, ammonia nitrogen, and phosphorus) in wastewater to the surface of the biofilm, shortening the mass transfer distance. If the biofilm grows too thick, the inner microorganisms will die due to lack of oxygen, leading to biofilm aging and shedding. The hydraulic shear effect of aeration can control the biofilm thickness (usually maintained at 0.1~2 mm), keeping it with a highly active young bacterial population (outer proliferation zone), while promoting the shedding of aging biofilm and making room for the growth of new biofilm.

[0054] The working principle of this utility model is as follows: sewage is settled in sedimentation chamber 101, and a certain amount of flocculant is added. The sewage flocculates and settles in sedimentation chamber 101. After passing through the sawtooth baffle 102, the sewage overflows into overflow channel 103, and then enters overflow chamber 105 through overflow port 104. Under the pumping of sewage pump 16, the sewage is transported to reaction tank 2 for further treatment.

[0055] The dosing tank 10 stores microbial agents, which are added to the reaction tank 2 via the metering pump 11 to enhance specific functional bacterial groups (such as nitrifying bacteria, polyphosphate-accumulating bacteria, and bacteria that degrade recalcitrant organic matter), thereby improving the system's shock resistance or treatment efficiency. This also facilitates the biological treatment effect of the biofilm treatment tank 3.

[0056] The polypropylene filaments on the biofilm packing 5 serve as a carrier for the attachment and growth of microorganisms. Their core function is to provide a large attachment surface and habitat for microorganisms (such as bacteria, fungi, protozoa, etc.) to form a biofilm, thereby efficiently degrading pollutants in wastewater.

[0057] The wastewater is regulated in equalization tank 4, where agitator 7 homogenizes the wastewater composition and ensures the pH value of the water. The wastewater is then pumped into collection tank 12 for storage, in preparation for further water treatment.

[0058] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0059] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
