Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to an anaerobic reactor influent regulation system. Background Technology

[0002] Anaerobic reactors are the core equipment for degrading organic pollutants in wastewater treatment. Their treatment efficiency is significantly affected by the influent water quality (such as pH value, alkalinity, COD load, and calcium ion concentration) and hydraulic conditions (such as upflow velocity).

[0003] Currently, traditional anaerobic reactor influent conditioning systems pre-treat high-concentration organic wastewater through acidification tanks before it enters the anaerobic reactor. However, the acidification process easily leads to a drop in pH and insufficient alkalinity, requiring the addition of liquid alkali for adjustment, which is costly and cannot simultaneously control COD and calcium ion concentrations. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an anaerobic reactor influent regulation system, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: an anaerobic reactor influent regulation system, comprising an aerobic secondary sedimentation tank, an acidification tank on one side of the aerobic secondary sedimentation tank, a regulating mechanism between the acidification tank and the aerobic secondary sedimentation tank, the regulating mechanism comprising a conveying pipe fixedly connected to the aerobic secondary sedimentation tank, a return water pump fixedly connected to one side of the conveying pipe, a return water pool fixedly connected to one side of the return water pump, the output end of the return water pump communicating with the return water pool, a connecting pipe fixedly connected to the side of the return water pool away from the return water pump, the end of the connecting pipe away from the return water pool communicating with the acidification tank, a flow meter fixedly connected to the surface of the connecting pipe, an electric regulating valve fixedly connected to one side of the flow meter, the electric regulating valve fixedly connected to the connecting pipe, a stirring mechanism on the top of the acidification tank, and a cleaning mechanism on one side of the stirring mechanism.

[0006] In a preferred embodiment, the stirring mechanism includes a motor, which is fixedly connected to the acidification tank. A drive wheel is fixedly connected to the output end of the motor. A belt is fitted on the inner wall of the drive wheel, and a driven wheel is fitted on one side of the belt. A rotating frame is fixedly connected to the bottom of the driven wheel. The rotating frame is rotatably connected to the acidification tank. An electric push rod is rotatably connected inside the rotating frame and is fixedly connected to the acidification tank. A rotating rod is slidably connected to the bottom of the rotating frame, and a stirring blade is fixedly connected to the outer surface of the rotating rod. The electric push rod is rotatably connected to the rotating rod.

[0007] By adopting the above technical solution, the output end of the motor drives the drive wheel to rotate, which in turn drives the belt, which in turn drives the driven wheel to rotate, which in turn drives the rotating frame to rotate, which in turn drives the rotating rod to rotate, which in turn drives the stirring blade to rotate, which in turn stirs the liquid inside the acidification tank. The extension and retraction of the electric push rod allows for height adjustment of the rotating rod and stirring blade, increasing the stirring area of ​​the stirring blade and thus better stirring the liquid inside the acidification tank.

[0008] In a preferred embodiment, the cleaning mechanism includes a fixed block, which is fixedly connected to the acidification tank. An electric push rod is fixedly connected inside the fixed block, and a brush is fixedly connected to the telescopic end of the electric push rod.

[0009] By adopting the above technical solution, the electric push rod 2 is fixed by the fixing block, and then the telescopic end of the electric push rod 2 extends and retracts to drive the brush to move, and then the brush cleans the inside of the acidification tank, which can better clean the inside of the acidification tank.

[0010] In a preferred embodiment, a fixing frame is fixedly connected to the surface of the return water tank, and a solar panel is fixedly connected to the surface of the fixing frame. The solar panel, flow meter, and electric regulating valve are all electrically connected to the return water pump.

[0011] By adopting the above technical solution, a fixed frame is fixedly connected to the surface of the return water tank, and the solar panel is fixed by the fixed frame. The solar panel, flow meter and electric regulating valve are all electrically connected to the return water pump, which increases the power of the flow meter, electric regulating valve and return water pump, further reducing energy consumption. This can better reduce energy consumption.

[0012] In a preferred embodiment, a pH sensor is fixedly connected inside the acidification tank.

[0013] By adopting the above technical solution, a pH sensor is fixedly connected inside the acidification tank, and the pH sensor detects the pH value inside the acidification tank in real time, which can better detect the pH value inside the acidification tank.

[0014] In a preferred embodiment, both the rotating rod and the stirring blade are fixedly connected with a corrosion-resistant layer, which is an alumina ceramic component.

[0015] By adopting the above technical solution, a corrosion-resistant layer is fixedly connected to the surface of both the rotating rod and the stirring blade, and the corrosion-resistant layer further enhances the corrosion resistance of the rotating rod and the stirring blade, thus improving their corrosion resistance.

[0016] The beneficial effects of this application are: 1. This anaerobic reactor influent regulation system comprises a return water pump, a delivery pipe, a return water tank, a flow meter, an electric regulating valve, and a connecting pipe. When the pH of the acidification tank is lower than or exceeds the set value, the return water pump draws water from the aerobic secondary sedimentation tank into the delivery pipe, which then transports the water to the return water tank. The connecting pipe then transports the water from the return water tank to the acidification tank. The flow meter measures the water flow in the connecting pipe, and the electric regulating valve controls the opening and closing of the connecting pipe. This system utilizes the aerobic... The system features high alkalinity, high pH, ​​low COD, and low calcium ion concentration in the effluent from the secondary sedimentation tank. By adjusting the COD and calcium ion concentrations, pH, and alkalinity of the anaerobic influent, the system ensures the upward flow rate of the anaerobic system reaction. This avoids the problems of traditional anaerobic reactor influent regulation systems, which pretreat high-concentration organic wastewater through acidification tanks. However, the acidification process easily leads to a decrease in pH and insufficient alkalinity, requiring additional liquid alkali for adjustment, which is costly and cannot simultaneously control COD and calcium ion concentrations. This system improves practicality.

[0017] 2. This anaerobic reactor influent regulation system, by setting up an electric push rod II, a fixing block and a brush, fixes the electric push rod II by the fixing block, and then the extension and retraction of the extension and retraction end of the electric push rod II drives the brush to move, and the brush cleans the pH sensor inside the acidification tank. This avoids the problem that traditional anaerobic reactor influent regulation systems cannot clean the pH sensor inside the acidification tank, thus improving practicality.
