DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0047] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0048] like Figure 1-Figure 8As shown, an automated sewage treatment system provided by the present invention includes a pretreatment system, a biochemical treatment system, a sludge treatment system, a deep treatment system and an automated control system, wherein the pretreatment system, the biochemical treatment system and the deep treatment system are connected in sequence, the biochemical treatment system includes a sedimentation tank, the sludge treatment system is connected to the sedimentation tank, and the pretreatment system, the biochemical treatment system, the sludge treatment system and the deep treatment system are all connected to the automated control system;

[0049] The sedimentation tank comprises a tank body 1, one end of the tank body 1 is connected to a water inlet pipe 10, the other end of the tank body 1 is connected to a drain pipe 6, a mud collecting tank 4 is provided at the inner bottom of the tank body 1, and a sealing shell 11 is fixedly installed on both sides of the tank body 1, and a mud shoveling assembly 7 is slidably installed inside the two sealing shells 11, and the mud shoveling assembly 7 is used to push the mud at the bottom of the tank body 1 to the inside of the mud collecting tank 4, and also includes:

[0050] A power mechanism 5, wherein the power mechanism 5 is installed on the tank body 1, and an output end of the power mechanism 5 is connected to one end of a shoveling assembly 7, and the power mechanism 5 is used to drive the shoveling assembly 7 to reciprocate, so that the shoveling assembly 7 can shovel the sludge into the sludge collecting tank 4;

[0051] The mud discharge component 3 is installed on the tank body 1, the input end of the mud discharge component 3 extends into the mud collecting tank 4, the output end of the mud discharge component 3 is connected to the sludge treatment system, and the mud discharge component 3 is used to transport the sludge in the mud collecting tank 4 to the sludge treatment system.

[0052] During the sewage treatment process in the sedimentation tank, the power mechanism 5 can drive the shoveling assembly 7 to move, and then push the sludge in the tank body 1 into the sludge collecting tank 4. The sludge discharge assembly 3 transports the sludge in the sludge collecting tank 4 to the sludge treatment system without cutting off the water inlet of the sedimentation tank, thereby improving work efficiency.

[0053] The pretreatment system includes a screen tank, a regulating tank, a neutralization tank, and a grit tank.

[0054] Screen tank treatment: The sewage first passes through the coarse and fine screens to intercept and remove larger suspended and floating objects in the sewage, such as plastic bags, branches, etc. This process is usually carried out by an automated screen cleaner, which drives the rake chain to rotate through a motor to effectively remove debris.

[0055] Equalization tank treatment: The wastewater from the screen tank is collected into the equalization tank, and the wastewater is initially mixed and homogenized through natural sedimentation, mechanical stirring, etc., to stabilize the flow, water quality and temperature of the wastewater.

[0056] Neutralization tank treatment: The sewage treated in the regulating tank enters the neutralization tank. According to the acid-base properties of the sewage, an appropriate amount of neutralizer is added automatically or manually. The neutralizer reacts with the acid or alkali in the sewage to generate salt substances and water. By controlling the amount of neutralizer added and the reaction conditions, the pH value of the sewage is ensured to reach the preset range (usually between 6-9).

[0057] Grit treatment: After being treated in the neutralization tank, the sewage enters the grit tank, where gravity is used to settle the sand, inorganic particles and sediment produced after the neutralization reaction in the sewage, further purifying the water quality to reduce the impact on subsequent treatment processes. This process can use equipment such as cyclone grit chambers to improve grit efficiency.

[0058] The biochemical treatment system includes biological pool and sedimentation tank treatment;

[0059] Biological pool treatment: The pre-treated sewage enters the biological pool, where the organic matter in the sewage is converted into stable inorganic matter through the metabolism of microorganisms. The biological pool is usually equipped with an aeration device to provide sufficient oxygen for the microorganisms and promote the biochemical reaction. At the same time, the fan of the biological pool needs to be started and stopped at a fixed time, fixed point and fixed quantity to ensure the activity of the microorganisms and the treatment effect.

[0060] Sedimentation tank treatment: The sewage treated in the biological tank enters the sedimentation tank, where the suspended matter, colloids and other substances in the sewage are condensed and settled through natural sedimentation or the addition of chemicals (such as coagulants). A stirrer is installed in the sedimentation tank to accelerate the mixing and reaction of chemicals and sewage.

[0061] The sludge treatment system includes sludge tank treatment;

[0062] Sludge pool treatment: The sludge generated during the sedimentation tank treatment process is discharged into the sludge pool, which reduces, stabilizes and renders it harmless. The sludge treatment process includes fermentation, disinfection, dehydration and other steps, and ultimately converts the sludge into resource products such as biogas and fertilizers.

[0063] The deep treatment system includes filtration tank and disinfection tank treatment;

[0064] Filter pool treatment: The water from the sedimentation tank enters the filter pool, and the suspended solids, organic matter and other impurities in the sewage are further removed through the filtering effect of the filter material. An appropriate amount of reagents (such as filter aids) can be added to the filter pool to improve the filtering effect. At the same time, the filter pool needs to start the aeration fan regularly for cleaning to remove the dirt on the filter material and restore the filtering performance.

[0065] Disinfection: The sewage treated in the filter tank usually needs to be disinfected to kill viruses, bacteria and other microorganisms to ensure that the effluent water quality meets the discharge standards. Disinfection methods include ultraviolet disinfection, ozone disinfection, chlorine disinfection, etc.

[0066] Automated control systems include data acquisition and monitoring, automatic control and optimization;

[0067] Data collection and monitoring: By installing monitoring and surveillance equipment (such as sensors, meters, and cameras) at each sewage treatment site, the water quality, flow rate, pH value, dissolved oxygen and other parameters of the inlet and outlet water, as well as the monitoring screens of each sewage treatment site, are monitored in real time to provide data support for control;

[0068] Automatic control and optimization: Based on monitoring data and process requirements, programmable logic controllers (PLC) or distributed control systems (DCS) and other equipment are used to achieve automatic control of sewage treatment sites, including water flow rate control, aeration volume control, sludge treatment control, and dosage control. At the same time, through big data analysis technology and artificial intelligence technology, intelligent optimization and decision support for sewage treatment processes are carried out.

[0069] The device uses an automated control system that can monitor in real time the water quality, flow, pH value, dissolved oxygen and other parameters of the inlet and outlet water, as well as the monitoring images of each sewage treatment site. At the same time, through big data analysis technology and artificial intelligence technology, it can automatically and intelligently optimize and support decision-making for the sewage treatment process, reducing the workload of manual monitoring and operation.

When the sludge accumulates to the top of the shovel bucket 74, the sludge will squeeze the pressure switch 16 through the trigger plate 15. The pressure switch 16 connects the power supply of the telescopic rod 72, so that the telescopic rod 72 drives the shovel bucket 74 to rise, so that the top of the shovel bucket 74 rises to the upper surface of the sludge, and then the power mechanism 5 continues to drive the shovel assembly 7 to move. At this time, the shovel bucket 74 no longer scrapes the sludge, thereby preventing the sludge from being shoveled. The top of the bucket 74 overflows, and after the mud shoveling bucket 74 sends the sludge to the mud collecting tank 4, the power mechanism 5 drives the mud shoveling assembly 7 to return, and then the telescopic rod 72 drives the mud shoveling bucket 74 to descend again, so that the bottom of the mud shoveling bucket 74 is flush with the inner bottom of the pool body 1, and then the power mechanism 5 drives the mud shoveling assembly 7 again to scrape the sludge, and the above actions are repeated until the sludge in the pool body 1 is cleaned up, and then the power mechanism 5 drives the mud shoveling assembly 7 back to the end of the pool body 1 close to the drain pipe 6 for the next cleaning.

[0085] In order to drive the stirring shaft 86 and the stirring plate 87 to rotate, the stirring mechanism 8 also includes a second motor 81, which is fixedly mounted on the side of the pool body 1, and the output shaft of the second motor 81 is fixedly connected to a rotating rod 84, and the rotating rod 84 extends to the side of the waterproof mounting tube 82 and is fixedly connected to a plurality of worms 83, and one end of each of the plurality of stirring shafts 86 is fixedly connected to a worm gear 85, and the plurality of worm gears 85 are respectively meshed and connected with the plurality of worms 83;

[0086] In order to improve the stirring effect, two adjacent stirring plates 87 are staggered up and down, so that the sewage can be mixed horizontally and the mixing effect of the reagent and sewage can be improved;

[0087] A partition plate 2 is also fixedly connected to the interior of the pool body 1, and a space is left between the bottom of the partition plate 2 and the inner bottom of the pool body 1. The sewage entering the pool body 1 from the water inlet pipe 10 will pass between the partition plate 2 and the pool body 1, so that the sewage and the reagent can be fully mixed, avoiding the situation where the sewage flows out before being mixed with the reagent, thereby improving the treatment quality of the sewage.

[0088] Workflow:

[0089] The sewage flowing out of the biological pool is introduced into the pool body 1 from the water inlet pipe 10, the valve is opened, and the medicine in the storage box 94 falls into the pool body 1 from the discharge pipe 95, the medicine and the sewage are mixed, and the second motor 81 is started. The second motor 81 drives the worm gear 85, the stirring shaft 86 and the stirring plate 87 to rotate through the rotating rod 84 and the worm 83. The stirring plate 87 stirs the sewage and the medicine to accelerate the mixing of the medicine and the sewage, and then the sewage flows out through the space between the partition plate 2 and the bottom of the pool body 1, and finally flows into the filter pool from the drain pipe 6;

[0090] When cleaning the sludge in the pool body 1, the first motor 56 is started, the first motor 56 drives the first rope drum 53 and the second rope drum 55 to rotate, the first rope drum 53 and the second rope drum 55 drive the pull rope 51 to move, the pull rope 51 drives the slider 71 to move, the slider 71 drives the telescopic rod 72 and the mud shoveling bucket 74 to move through the cross bar 73, the mud shoveling bucket 74 shovels the mud on the inner bottom of the pool body 1, when the sludge accumulates to the top of the mud shoveling bucket 74, the sludge squeezes the pressure switch 16 through the trigger plate 15, thereby turning on the power of the telescopic rod 72, the telescopic rod 72 drives the mud shoveling bucket 74 to rise, so that the bottom of the mud shoveling bucket 74 is higher than the upper surface of the sludge, so as to prevent the mud shoveling bucket 74 from scraping the sludge again, thereby preventing the sludge from overflowing from the top of the mud shoveling bucket 74 and preventing the sludge from mixing with sewage again;

[0091] The shovel 74 is moved downwardly by the first motor 56, and the shovel 74 is moved upwardly by the second motor 56, so that the shovel 74 is moved downwardly, thereby pouring the sludge in the shovel 74 into the sludge collecting tank 4. Then the first motor 56 drives the shovel 74 to move in the opposite direction, so that the shovel 74 returns to the end of the pool body 1 close to the drain pipe 6. Under the action of the return block 13, the insertion rod 172 is inserted into the card slot 171 again, and then the telescopic rod 72 drives the shovel 74 to descend, so that the bottom of the shovel 74 is attached to the inner bottom of the pool body 1, and then the first motor 56 drives the shovel 74 to move again, and the above actions are repeated until all the sludge at the bottom of the pool body 1 is shoveled into the sludge collecting tank 4, and then the shovel 74 returns to its initial position, waiting for the next mud cleaning.

[0092] Finally, the sewage pump 32 is started, and the sewage pump 32 extracts the sludge in the sludge collecting tank 4 through the sludge inlet pipe 31 and transports it to the sludge treatment system, and the sludge treatment system treats the sludge.
