The part of the sewage inlet pipe 18 inserted into chamber 3 is also evenly provided with water distribution holes to achieve the effect of uniform water distribution.

[0037] The housing 1 is fixedly connected to the equipment base 21. Two aeration main pipes 22 are fixedly connected in parallel inside the equipment base 21.

[0044] Wastewater inlet pipe 18 receives water through an inlet lift pump, the inlet of which is connected to the pretreatment device.

Clean water outlet pipe 20 is connected to ultraviolet disinfection equipment via a pipeline. Aeration main pipe 22 is connected to an aerator, and normally open solenoid valves are connected to all aeration main pipes 22. The normally open solenoid valves, aerator, electromagnetic flow meter, electric regulating valve, inlet lift pump, and ultraviolet disinfection equipment are all controlled by a PLC control cabinet. The pretreatment device consists of a septic tank, grease trap, screen, equalization tank, control sewage pump, and various pipe fittings. Domestic sewage and catering wastewater are collected in the septic tank and grease trap, and after merging, pass through a screen (screen spacing 5-8mm) to intercept lumps and flocs mixed in the incoming water. The screen should be manually cleaned regularly. Then it enters the equalization tank, which is used to regulate the instability of the incoming water. Then it is lifted by the control pump to the sewage inlet pipe 18 of this equipment. The sludge discharge pipe 26 is connected to the external sludge collection equipment, and the sludge can be pumped out by the sludge pump.

[0045] The pollutant removal mechanism of multi-component catalytic composite carriers includes:

[0046] 1) Micro-region electrocatalysis generates highly oxidizing free radicals: Due to the different electrode reactions of different phase regions in water, a micro-region potential difference is formed on the surface of the multi-component catalytic composite support. The Fe3C region is the anode region, mainly characterized by the loss of electrons by iron and other components; the C region is the cathode region, mainly characterized by the gain of electrons by hydrogen ions and other components under anaerobic acidic conditions, while oxygen reduction occurs in the presence of oxygen in neutral or alkaline environments; various highly oxidizing free radicals are generated near the surface of the micro-region electrode under the action of an electric field.

[0047]

[0048] 2) Electrocatalytic oxidation (advanced oxidation) for COD removal: Free radicals such as OH· generated near the surface of the micro-electrode create a strong redox reaction environment in different regions near the carrier surface, which can efficiently decompose COD in water into CO2 and H2O and release energy.

[0049]

[0050] 3) Catalytic oxidation-autotrophic denitrification coupled denitrification: The reduction of oxygen creates a slightly alkaline microenvironment in the carrier pores, providing a suitable environment for the activity of nitrifying and denitrifying bacteria. After a certain period of cultivation, a stable denitrification reaction system coupled with electrocatalytic oxidation and heterotrophic autotrophic denitrification is formed. The porous carrier provides a large space for denitrification, improving the nitrogen removal efficiency.

[0051]

[0052] 4) Micro-electrolysis-catalytic oxidation-precipitation phosphorus removal: The ferrous iron produced by micro-electrolysis of a small amount of iron is further oxidized to ferric iron, and then reacts with phosphate ions to remove phosphorus. The product, iron phosphate, serves as a catalyst for advanced oxidation to supplement the catalytic oxidation capacity of the system.

[0055] Fe 3+ +PO4 3- +2H₂O→FePO₄·2H₂O↓

[0056] Multi-element catalytic composite carrier is the core material of honeycomb modular equipment for wastewater treatment. It is formed by fusing multiple catalysts with multiple metals through high-temperature smelting to form an integrated multi-element alloy skeleton (Fe3C-C based), ensuring the continuous and efficient iron-carbon (Fe-C) "galvanic cell" effect.

[0057] The microporous structure provides a large specific surface area and uniform water and air flow channels, resulting in higher current density and better catalytic reaction effects for wastewater treatment. It is highly active, lightweight, non-passivating, non-caking, has a fast reaction rate, and is stable and effective in long-term operation. Adjusting the proportions of catalytic components for different types of wastewater improves reaction efficiency and expands its application range in wastewater treatment. This packing material has a large specific surface area and high porosity, exhibiting strong adsorption and biocompatibility, which is conducive to the proliferation and metabolism of microorganisms on this packing material, promoting the formation of microbial communities and facilitating coupling with biochemical processes for better treatment results. The multi-element catalytic composite carrier can remove pollutants such as organic matter, suspended solids, ammonia nitrogen, nitrate nitrogen, heavy metals, and algae from wastewater through physicochemical catalytic reactions and microbial metabolism, while inhibiting odor generation. It can remove pollutants from incoming water without the need for any added chemicals during the removal process. The multi-element catalytic composite carrier does not caking and requires no addition for up to twenty years.

[0058] The working principle of this utility model is as follows:

[0059] Domestic sewage undergoes a preliminary treatment process, which filters out impurities such as shredded paper, plastics, and fibers, and regulates the influent flow to ensure a stable water supply for downstream equipment. After meeting the influent conditions for deep biochemical coupling treatment, the treated water enters the honeycomb modular sewage treatment unit for nitrogen and phosphorus removal. The treated water is then either discharged or reused.

[0060] The aerator is responsible for supplying oxygen to the equipment and backflushing the inside of the housing 1.

[0061] The control pump is responsible for the power system of wastewater treatment.

[0062] The honeycomb modular wastewater treatment equipment performs deep biochemical coupled treatment of wastewater.

[0063] In this process, the multi-element catalytic composite carrier is the core component. After pretreatment, domestic sewage is pumped into the honeycomb modular sewage treatment equipment and flows through the multi-element catalytic composite carrier and overflow weir 16 into the corresponding chamber. The chamber is equipped with the multi-element catalytic composite carrier, and the sewage undergoes deep purification as it flows through the carrier.

[0064] An aeration system is installed at the bottom of the chamber, which provides an appropriate amount of oxygen. Through the biochemical coupling effect of the multi-element catalytic composite carrier, the wastewater is treated in depth.

[0065] The honeycomb modular wastewater treatment equipment consists of multi-level chambers and a multi-element catalytic composite carrier. It removes COD through electrocatalysis in the carrier micro-zones, generates strong oxidizing free radicals, removes COD through electrocatalytic oxidation (advanced oxidation), removes nitrogen through catalytic oxidation-autotrophic denitrification coupling, and removes phosphorus through micro-electrolysis-catalytic oxidation-precipitation. It achieves the removal of pollutants such as COD, ammonia nitrogen, total nitrogen, total phosphorus, and SS without the addition of chemicals and meets the discharge standards. It can also be reused for greening, flushing, etc.

[0066] The PLC control cabinet outputs power supplies of different voltages to drive various electrical components, and the PLC program controls the equipment to work normally.

[0067] Domestic sewage first undergoes pretreatment, which intercepts and filters out impurities such as shredded paper, plastic, and fibers, and adjusts the sewage to meet the influent conditions for entering the main equipment.

[0068] 1. Water Inlet System

[0069] Wastewater is pumped by the inlet pump and enters the deep treatment chamber through the wastewater inlet pipe 18. Then it enters the first chamber 3, the second chamber 4, the third chamber 5, the fourth chamber 6, the fifth chamber 7, the sixth chamber 8, the seventh chamber 9, the eighth chamber 10 and the ninth chamber 11 in sequence. After being purified by different multi-element catalytic composite carriers, the wastewater enters the ultraviolet disinfection equipment through the purified water outlet pipe 20 connected to the tenth chamber 12 for disinfection. The treated water is then discharged or reused.

[0070] 2 Aeration System

[0071] The gas, generated by the aerator and at a certain volume and pressure, enters the chambers under the control of a normally open solenoid valve, thus increasing oxygenation, accelerating the wastewater treatment reaction, and improving reaction efficiency. When the system requires anoxic treatment, one solenoid valve can be automatically closed, and the corresponding chamber group will undergo anoxic treatment, while the remaining chambers will undergo aerobic treatment. Furthermore, aeration also serves to backflush the carrier, preventing clogging by debris.

[0072] 3 Deep Processing Unit

[0073] It consists of a first chamber 3, a second chamber 4, a third chamber 5, a fourth chamber 6, a fifth chamber 7, a sixth chamber 8, and a seventh chamber 9. The chambers are filled with different multi-element catalytic composite supports, which are mainly used to remove COD, ammonia nitrogen, total nitrogen, total phosphorus, and SS.

[0074] The tenth chamber, 12, is a settling chamber. After treatment, the water passes through this chamber and is either discharged or reused via ultraviolet disinfection equipment.

[0075] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
