[0002] With the acceleration of global industrialization and urbanization, the problem of water scarcity is becoming increasingly severe. On the one hand, urban water consumption for production and daily life is rising sharply, highlighting the contradiction between freshwater supply and demand; on the other hand, the amount of sewage discharged from municipal pipe networks continues to increase, and the direct discharge of untreated sewage not only wastes water resources but also seriously pollutes natural water bodies such as rivers and lakes, exacerbating ecological imbalance.

[0003] A search revealed Chinese Patent Publication No. CN216711855U, which discloses a municipal sewage reuse system, relating to the technical field of sewage reuse devices.

The lower right side of the microbial treatment tank is connected to the upper left side of an aeration tank via a pipe. The lower right side of the aeration tank is connected to a fine filter via a pipe. Pumps are installed on all pipes. The fine filter is connected to the upper right side of a disinfection tank via a pipe. A disinfection box is installed at the upper end of the disinfection tank, and a drain pipe with a valve is installed at the lower right end of the disinfection tank. This invention enables primary filtration with minimal clogging, saving time and increasing efficiency. It is convenient to use, easy to operate, and has a simple structure, improving efficiency and enabling rapid sewage treatment.

However, the filter device cannot achieve primary filtration during use, which easily leads to clogging during processing. Moreover, it is not thorough in fine filtration and has poor stability. Therefore, a municipal sewage reuse system is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a municipal sewage reuse system, which aims to improve the problem of easy clogging in some sewage treatment devices.

[0010] Preferably, the connecting pipes are used to steadily transport the pre-filtered wastewater. The reasonable pipe diameter and layout ensure stable water flow, reduce head loss, avoid wastewater retention and backflow, and ensure that the wastewater is efficiently transported to the equalization tank. The equalization tank equalizes the water quality and quantity, prevents the subsequent treatment units from being impacted, improves the treatment efficiency of equipment such as the microbial treatment tank, enhances the overall stability and adaptability of the system, and reduces operation and maintenance costs.

The rotating motor drives the rotating connecting column to rotate, and its rotating connection design with the outside of the primary filter forms a stable rotating fulcrum, making the eccentric swing motion more precise and efficient. This structure transforms the circular motion of the motor into the reciprocating sliding of the cleaning brush, effectively removing impurities from the coarse filter screen.

[0020] Preferably, the equalization tank, microbial treatment tank, aeration tank, fine filter and disinfection tank are connected in sequence to build an efficient sewage purification system. The equalization tank equalizes the water quality and quantity, creating stable conditions for subsequent treatment. The microbial treatment tank uses activated sludge to degrade organic matter and reduce the pollution load. The aeration tank accelerates microbial metabolism through oxygenation. The fine filter deeply filters out tiny impurities. The disinfection tank kills pathogens. Each unit works together to remove organic pollutants, suspended solids and pathogenic microorganisms from sewage, ensuring that the reused water meets safety standards, realizing the resource utilization of sewage, alleviating urban water pressure, and achieving both environmental and social benefits.

[0021] By adopting the above technical solution, a grid filter layer is fixedly connected to the inner side of the primary filter, a fine filter screen is fixedly connected to the inner side of the primary filter, a valve is fixedly connected to the outside of the disinfection tank, a main water inlet pipe is fixedly connected to the outside of the primary filter, and a disinfection box is fixedly connected to the outside of the disinfection tank.

[0022] Preferably, the inlet pipe stably collects sewage from the municipal pipe network and introduces it into the primary filter.

The valve can flexibly adjust the sewage flow rate and direction to ensure stable system operation. All components work together to improve sewage reuse efficiency and water quality safety.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. In this utility model, when the rotating motor is running, it drives the rotating connecting column one to rotate, which in turn drives the rotating connecting rod one and the rotating connecting rod two in sequence.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0032] A municipal sewage reuse system, referring to Figure 1 , Figure 3 and Figure 4 The system includes a primary filter 1, which serves as a wastewater reuse system. It has a multi-layer filtration structure. The grid filter layer 10 can intercept larger floating objects in the wastewater, such as branches and plastic bags, to prevent these debris from clogging subsequent pipes and equipment. The coarse filter 9 filters out smaller particulate impurities, while the fine filter 11 can intercept even finer suspended solids, reducing the pressure on subsequent treatment.

[0033] A coarse filter screen 9 is fixedly connected to the inner side of the primary filter 1. A cleaning mechanism 14 is slidably connected to the outer side of the coarse filter screen 9. The cleaning mechanism 14 includes a drive assembly 141 for driving. The drive assembly 141 is fixedly connected to the inner side of the primary filter 1. A rotating connecting rod 142 is fixedly connected to the outer side of the drive assembly 141. A rotating connecting rod 143 is rotatably connected to the outer side of the rotating connecting rod 142. A rotating motor 1411 drives the rotating connecting rod 1412 to rotate. The eccentric design causes the rotating connecting rod 142 to swing, which drives the rotating connecting rod 143 to perform a compound motion. A rotating connecting rod 144 is fixedly connected to the outer side of the rotating connecting rod 143, i.e., the end away from the rotating connecting rod 142. The rotating connecting rod 144 and the support connecting block 146 provide a stable fulcrum for the movement.

[0034] A support connecting block 146 is rotatably connected to the outside of the rotating connecting column 144. A sliding connecting block 145 is fixedly connected to the bottom of the support connecting block 146. The sliding connecting block 145 slides back and forth in the slide rail on the inner wall of the primary filter 1, driving the cleaning brush 147 to stick tightly to the surface of the coarse filter screen 9. The cleaning brush 147 is fixedly connected to the outside of the support connecting block 146. The cleaning brush 147 slides on the surface of the coarse filter screen 9, promptly removing impurities attached to the coarse filter screen 9, preventing clogging, maintaining the filtration efficiency of the coarse filter screen 9, extending its service life, and ensuring the continuous and efficient operation of the primary filter 1 stage. The drive assembly 141 includes a rotating motor 1411, and the drive assembly 141 uses the rotating motor 1411 as a power source.

[0035] The external fixed connection of the rotary motor 1411 is to the inside of the primary filter 1. The drive end of the rotary motor 1411 is fixedly connected to the first rotary connecting column 1412. The drive component 141 in the cleaning mechanism 14 uses the rotary motor 1411 as the power source. When the rotary motor 1411 runs, it drives the first rotary connecting column 1412 to rotate. The external rotatable connection of the first rotary connecting column 1412 is to the outside of the primary filter 1. The external rotatable connection of the first rotary connecting rod 142 is to the outside of the primary filter 1. The external rotatable connection of the second rotary connecting rod 143 is to the outside of the primary filter 1. The external slidable connection of the sliding connecting block 145 is to the inside of the primary filter 1. The external slidable connection of the support connecting block 146 is to the inside of the primary filter 1.

[0036] The sliding connecting block 145 is externally slidably connected to the outside of the coarse filter screen 9. The coarse filter screen 9 plays a key filtering role. The bottom of the cleaning brush 147 is slidably connected to the outside of the coarse filter screen 9. The outside of the cleaning brush 147 is slidably connected to the outside of the primary filter 1. It has good flexibility and wear resistance, which can effectively remove impurities without damaging the filter screen. It can be started by timer or pressure sensing. The cleaning mechanism 14 can avoid frequent manual cleaning and reduce operation and maintenance costs.

[0037] Specifically, the multi-layer filtration structure of the primary filter 1 effectively removes impurities of different particle sizes from the wastewater, reducing the load on subsequent treatment units and improving the overall system efficiency. The cleaning mechanism 14, powered by a rotating motor 1411, drives the cleaning brush 147 to slide via a linkage transmission, periodically or as needed, cleaning impurities on the surface of the coarse filter screen 9 to prevent clogging and ensure the continuous and efficient operation of the primary filter 1. This extends the service life of the coarse filter screen 9, reduces replacement costs, and the automated operation of the cleaning mechanism 14 significantly reduces the frequency of manual inspection and cleaning, lowers labor costs, maintains the efficient operation of the primary filter 1, ensures the quality of wastewater pretreatment, lays the foundation for subsequent deep treatment stages, improves the quality of reclaimed water, and contributes to the recycling and sustainable development of urban water resources.

[0038] Reference Figures 1 to 3The primary filter 1 is fixedly connected to a connecting pipe 2, which serves to transport sewage and stably deliver the sewage after primary filtration to the equalization tank 3. The end of the connecting pipe 2 that is away from the primary filter 1 is fixedly connected to the equalization tank 3. The equalization tank 3 is fixedly connected to the outside of the equalization tank 3. The microbial treatment tank 4 is fixedly connected to the outside of the equalization tank 3. The microbial treatment tank 4 uses the metabolism of microorganisms to degrade organic pollutants in the sewage. The microorganisms on the activated sludge or biofilm cultivated in the tank adsorb and decompose the organic matter in the sewage.

[0039] An aeration tank 5 is fixedly connected to the outside of the microbial treatment tank 4. Air is introduced into the tank through aeration equipment to fully mix and contact the sewage with the activated sludge, promote the decomposition of pollutants by microorganisms, and accelerate the metabolic rate of microorganisms to improve the sewage treatment effect. A fine filter 6 is fixedly connected to the outside of the aeration tank 5. The fine filter 6 performs deep filtration on the sewage after microbial treatment and aeration to remove residual fine suspended solids, colloidal substances and some microorganisms, further improving the water quality.

[0040] The external fixed connection of the fine filter 6 is a disinfection tank 7. The internal fixed connection of the primary filter 1 is a grid filter layer 10. The internal fixed connection of the primary filter 1 is a fine filter screen 11. The external fixed connection of the disinfection tank 7 is a valve 12, which is used to control the flow direction and flow rate of sewage in the system. By opening or closing the valve 12, the sewage volume of each treatment unit can be adjusted, realizing flexible operation and maintenance of the system. The external fixed connection of the primary filter 1 is a main inlet pipe 8, which is the inlet for sewage to enter the reuse system. It is connected to the municipal pipe network and introduces the collected sewage into the primary filter 1. The external fixed connection of the disinfection tank 7 is a disinfection box 13. The disinfection tank 7 uses the disinfectant provided by the disinfection box 13 to kill pathogenic microorganisms such as bacteria and viruses remaining in the sewage, preventing them from causing safety hazards to reuse and ensuring that the reused water meets hygiene standards.

[0041] Specifically, through multiple layers of purification, including primary filtration 1 and fine filtration, combined with microbial treatment and disinfection, impurities and pollutants in wastewater are effectively removed, enabling water resource recycling, alleviating urban water pressure, and improving water resource utilization. Connecting pipe 2 and valve 12 controls the direction and flow of wastewater, ensuring stable system operation. At the same time, regulating tank 3 balances water quality and quantity, reducing the load on subsequent treatments, extending equipment lifespan, and reducing equipment replacement and maintenance costs. Cleaning mechanism 14 automatically maintains coarse filter screen 9, reducing the frequency of manual cleaning and lowering labor costs. The treated reclaimed water meets hygiene standards and can be safely used in areas such as greening irrigation and road washing, reducing the need for fresh water intake, reducing the environmental impact of wastewater treatment, and combining environmental and economic benefits to contribute to sustainable urban development.

[0042] The implementation principle of this application embodiment is as follows: When the rotating motor 1411 starts running, it drives the rotating connecting column 1412 to rotate, thereby driving the rotating connecting rod 142 to rotate, which in turn drives the rotating connecting rod 142 to move, thereby driving the rotating connecting rod 143 to rotate. At the same time, the rotating connecting column 144 drives the sliding connecting block 145 to slide, and the supporting connecting block 146 provides support for the movement of the rotating connecting column 144, thereby ensuring the normal sliding of the sliding connecting block 145. When the sliding connecting block 145 starts to slide, it drives the cleaning brush 147 to slide, thereby achieving the effect of cleaning the surface of the coarse filter screen 9, thereby reducing the occurrence of clogging events.

[0043] Municipal sewage flows into the primary filter 1 through the main inlet pipe 8. The bar screen 10, coarse filter 9, and fine filter 11 sequentially intercept impurities of different particle sizes. After primary filtration, the sewage is transported to the equalization tank 3 via connecting pipe 2. After water quality and quantity are homogenized, it flows into the microbial treatment tank 4, where microorganisms on the activated sludge or biofilm adsorb and decompose organic matter. Subsequently, the sewage enters the aeration tank 5, where aeration equipment oxygenates the sewage and activated sludge, accelerating microbial metabolism. The fine filter 6 deeply filters residual suspended solids and other impurities. Finally, the sewage enters the disinfection tank 7, where disinfectant provided by the disinfection box 13 kills pathogenic microorganisms. Valve 12 allows for flexible adjustment of the sewage flow rate in each treatment unit, ensuring stable system operation and ensuring that the treated sewage meets reuse standards.

[0044] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
