Technical Field

[0001] This utility model belongs to the technical field of sewage treatment equipment, specifically relating to a device that uses photocatalytic technology to treat sewage containing high molecular weight compounds. Background Technology

[0002] Photocatalytic oxidation, as an advanced wastewater treatment technology, utilizes photocatalysts to oxidize and degrade organic matter and complexes in wastewater under light irradiation. This technology not only efficiently removes organic matter from wastewater but also treats difficult-to-decompose complexes, offering numerous advantages such as environmental friendliness, high efficiency, and low cost. However, current photocatalytic technologies have not yet been widely adopted, mainly due to the following disadvantages: Catalyst efficiency issues: Traditional photocatalysts, such as TiO2, have low catalytic efficiency and can only treat wastewater with low concentrations of pollutants. Equipment use and maintenance difficulties: Photocatalytic equipment is typically bulky, inconvenient to maintain and use, and consumes a lot of energy, making it difficult to compete with other wastewater treatment processes in terms of economics. Light source cost issues: The lifespan of light sources is short, requiring regular replacement, which undoubtedly increases the cost of wastewater treatment. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0019] See attached document Figure 1-4 A device for treating wastewater containing high molecular weight compounds using photocatalysis technology includes an intelligent power supply cabinet 4, a control system, and a reactor unit module 1. The reactor unit module 1 houses a photocatalytic reactor 3. The photocatalytic reactor 3 has an inlet 8 and an outlet 9. Wastewater enters the photocatalytic reactor 3 through the inlet 8 and flows out through the outlet 9 after treatment. The photocatalytic reactor 3 contains 10 photocatalytic units 5, each containing 10 photocatalytic tubes 6 installed in parallel. The outer surface of the photocatalytic tubes 6 is coated with a photocatalytic layer 7, which is a polymer semiconductor g-C3N4 coating. The photocatalytic tubes 6 in the photocatalytic unit are connected to the inlet 8 via pipes, allowing wastewater to enter the photocatalytic tubes 6 for photolysis. An ultraviolet amalgam lamp is installed inside the photocatalytic tube 6. The specific light radiation of the ultraviolet amalgam lamp has a wavelength of 254 nm, and the ultraviolet amalgam lamp is connected to the intelligent power supply cabinet 4.

[0020] The inner cavity of photocatalytic tube 6 is equipped with an ultraviolet amalgam lamp, which emits specific light radiation at a wavelength of 254nm. This wavelength of ultraviolet light itself has a strong bactericidal effect and high energy density, which can excite the coating on the outer surface of the photocatalytic tube to exchange electrons with the wastewater components in contact, thereby breaking down the molecular chains of organic components in the wastewater. The intelligent power supply cabinet 4 provides power to the ultraviolet amalgam lamps installed in each photocatalytic tube in the photocatalytic unit, ensuring the continuity and intensity of the radiation source. The ultraviolet amalgam lamps have a service life of 2-3 years, saving costs.

[0021] Specifically, during equipment operation, ultraviolet light of a specific wavelength continuously releases light energy. When the polymer semiconductor g-C3N4 coating is irradiated by this light, it absorbs the energy. Once the energy exceeds its threshold, the coating material is excited, generating photogenerated electrons and holes. These electrons and holes migrate to the surface of the catalytic coating. Electrons are captured by dissolved oxygen to form superoxide radicals, while holes are adsorbed onto the catalyst surface, oxidizing water and hydroxide ions into hydroxyl radicals. Both of these substances have strong oxidizing properties, thereby destroying the structure of the polymer compounds in contact with the coating surface and decomposing them into easily processed or even harmless small-molecule organic matter, ultimately achieving anti-fouling and purification functions. Within a program-set time period, the long chains of polymer compounds are destroyed by active superoxide and hydroxyl radicals, decomposing them into easily decomposed small-molecule chains. After the online detection sensor—a redox potentiometer—measures the values ​​and compares them with the set standard values, the purified wastewater is allowed to flow out from the outlet and connect to the external pipeline. After the wastewater enters the reactor equipment, it undergoes recycling treatment. The pollutant indicators in the wastewater are dynamically monitored using online equipment. Only when the monitored indicators reach the set standards is the wastewater allowed to flow into the next stage facility.

[0022] This equipment system features modular assembly, synchronous multi-level parallel operation, and fully automated control. It can be configured and combined according to the wastewater treatment capacity, providing customers with flexible and adaptable solutions. Simultaneously, the parallel design prevents production disruptions due to single-unit failures, ensuring stable continuous production. The equipment employs a DNC distributed control mode, allowing control of all auxiliary facilities from a single touchscreen – simple, clear, and easy to operate. The system automatically monitors and adjusts the equipment's operation, requiring minimal human intervention and significantly reducing labor costs. The equipment integrates various sensors and data acquisition devices, enabling customers to monitor the equipment's operational status anytime, anywhere, and promptly identify and resolve potential problems.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope of the present utility model based on the technical solution and the inventive concept of the present utility model are covered within the protection scope of the present utility model.
