Description

Technical Field

[0001] This invention relates to the field of municipal wastewater treatment technology, specifically to a modular combined municipal wastewater emergency treatment device and method. Background Technology

[0002] With the increasing urban population and the gradual increase in urban water demand and consumption, the insufficient capacity of municipal sewage collection and treatment has become increasingly apparent, and the pollution pressure of municipal sewage is the most serious. The sewage treatment of the entire city is carried out through municipal sewage treatment plants. However, when accidents occur at municipal sewage treatment plants or when the treatment equipment malfunctions, urban sewage will continue to be generated, and the municipal sewage treatment plants cannot stop the discharge, resulting in serious water pollution during their maintenance and expansion. Therefore, emergency treatment of municipal sewage needs to be properly addressed.

[0003] In the existing technology, the municipal sewage emergency treatment device has low treatment efficiency for municipal sewage, does not separate impurities in the sewage sufficiently, and is prone to clogging during use, resulting in poor stability. At the same time, the existing municipal sewage emergency treatment device can only perform simple filtration treatment on sewage, and the treated municipal sewage still needs to be purified, which increases the treatment cost of municipal sewage. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a modular combined municipal sewage emergency treatment device and method.

[0005] The technical solution of the present invention is as follows: a modular combined municipal sewage emergency treatment device, comprising a sedimentation component, a separation component and a filtration component arranged on a base and connected in sequence; the sedimentation component includes a sedimentation cylinder arranged on the base and a sewage pump arranged at the top of the sedimentation cylinder; an inlet pipe is provided at the upper end of the outer wall of the sedimentation cylinder; the input end of the sewage pump is connected to a first conduit communicating with the inside of the sedimentation cylinder, and the output end of the sewage pump is connected to a second conduit;

[0006] The separation assembly includes an outer cylinder mounted on a base via a bracket, a separation screen cylinder fitted inside the outer cylinder, a separation spiral rotatably engaged inside the separation screen cylinder, and a rotary motor located at the right end of the outer cylinder and providing power to the separation spiral; a connecting pipe connected to a second conduit is located at the left end of the outer cylinder; a guide hopper is located at the bottom end of the outer cylinder; the guide hopper is connected to the interior of the outer cylinder, and several guide pipes are equidistantly distributed at the bottom end of the guide hopper; a baffle plate fixedly connected to the inner wall of the outer cylinder is fitted on the outer right side of the separation screen cylinder; and a slag discharge pipe is located on the right side of the bottom surface of the outer cylinder.

[0007] The filter assembly includes a filter box mounted on the base and located below the outer cylinder, and a filter media box that is movably snapped into the upper part of the filter box; a clean water pipe is provided at the lower end of the outer wall of the filter box; and the filter media box is filled with clean water filter media.

[0008] Furthermore, a conical hopper is provided at the upper part of the sedimentation tank, and several interlocking isolation sleeves are provided at the bottom of the conical hopper. Each isolation sleeve is provided with a flow groove at the upper part; the first guide tube is connected to the area formed by the outermost isolation sleeve and the sedimentation tank.

[0009] Explanation: By setting conical hoppers and isolation sleeves inside the sedimentation tank, not only can the flow velocity of municipal sewage entering the sedimentation tank be reduced, but also the residence time of the sewage in the sedimentation tank is extended as the municipal sewage passes through the flow channels on each isolation sleeve in sequence, thereby improving the sedimentation effect of the sewage.

[0010] Furthermore, the conical hopper is slidably engaged with the sedimentation cylinder, and each isolation sleeve is movably inserted into the inner bottom of the sedimentation cylinder; a lifting winch is installed at the top of the sedimentation cylinder, and a sling that penetrates the sedimentation cylinder and is connected to the conical hopper is installed at the output end of the lifting winch; a cleaning pipe is installed at the lower end of the outer wall of the sedimentation cylinder.

[0011] Explanation: By movably placing the conical bucket and isolation sleeve inside the settling cylinder, and using a hoist to move the conical bucket and isolation sleeve up and down inside the settling cylinder, it is easy to clean the pollutants settled inside the settling cylinder and reduce the risk of blockage.

[0012] Furthermore, a movable baffle is provided at the right end of the separating mesh cylinder. The movable baffle is movably connected to the separating mesh cylinder via a plug rod. A damping spring is sleeved on the outside of the plug rod to abut against the inner wall of the separating mesh cylinder.

[0013] Explanation: The movable baffle prevents unseparated sewage from escaping through the right end of the separation screen cylinder. During the rotation of the separation spiral, the movable baffle moves to the right along the separation screen cylinder under the pressure of the pollutants. After the pollutants inside the separation screen cylinder are cleaned, the separation screen cylinder automatically resets under the action of the damping spring.

[0014] Furthermore, a movable sleeve is fitted around the outside of the separating screen cylinder. Several flushing nozzles are evenly distributed on the inner wall of the movable sleeve. Threaded seats and guide seats are respectively provided at the upper and lower ends of the outer wall of the movable sleeve. Inside the outer cylinder, there is a drive screw threadedly connected to the threaded seat and a guide rod slidably engaged with the guide seat. The right end of the drive screw passes through the outer cylinder and is connected to a first pulley. A second pulley is fitted around the right end of the separating screw, and the second pulley is connected to the first pulley via a belt drive. A telescopic hose is provided on the movable sleeve that passes through the outer cylinder.

[0015] Explanation: Since the second pulley is connected to the first pulley by belt drive, the rotation of the separating screw can drive the drive screw to rotate. The moving sleeve moves along the guide rod under the connection between the threaded seat and the drive screw. The flushing nozzle on the inner side of the moving sleeve is used to flush the pollutants adsorbed on the separating screen cylinder, so as to avoid clogging of the holes on the separating screen cylinder.

[0016] Furthermore, several stirring rods are rotatably engaged inside the filter box and below the packing mesh box; a gearbox is installed inside the filter box; each stirring rod passes through the gearbox, and each stirring rod is fitted with a connecting gear located inside the gearbox and meshing with each other; a stirring motor that provides power to one of the stirring rods is installed on the outer wall of the filter box; a dosing pipe is installed on the outer wall of the filter box and below the packing mesh box.

[0017] Instructions: Wastewater purification agents are added to the filtered wastewater through the dosing pipe. A stirring motor drives one of the stirring rods to rotate. At the same time, all the stirring rods rotate simultaneously under the meshing action of the connecting gears, which makes the wastewater purification agents and wastewater mix more evenly and helps to improve the purification effect of municipal wastewater.

[0018] Furthermore, each guide pipe is connected to a horizontal pipe at its bottom end, and each horizontal pipe has several water outlets evenly distributed on it.

[0019] Note: By installing a horizontal pipe at the bottom of the guide pipe, it is beneficial to improve the dispersion of sewage when it enters the filter box and improve the contact efficiency between sewage and water purification packing.

[0020] Furthermore, it also includes a PLC controller mounted on the base, a liquid level sensor installed inside the sedimentation tank, and the PLC controller electrically connected to the liquid level sensor, the sewage pump, and the rotary motor respectively.

[0021] Note: When the liquid level sensor detects that the liquid level inside the sedimentation tank has reached the preset value, the PLC controller controls the sewage pump and rotary motor to start, which helps to improve the automation level of the device and increase its working efficiency.

[0022] This invention also provides a modular combined municipal sewage emergency treatment method, based on the above-mentioned modular combined municipal sewage emergency treatment device, comprising the following steps:

[0023] S1. Connect the inlet pipe to the municipal sewage pipe. Municipal sewage enters the sedimentation tank through the inlet pipe. Large particles of impurities in the municipal sewage settle at the bottom of the sedimentation tank.

[0024] S2. The sewage that has settled inside the sedimentation tank is pumped into the separation screen cylinder by the sewage pump. Impurities in the sewage are trapped inside the separation screen cylinder. Then, the rotary motor is started to drive the separation screw to rotate. During the rotation of the separation screw, the impurities trapped inside the separation screen cylinder move to the right side of the separation screen cylinder and are discharged through the slag discharge pipe.

[0025] S3. After being separated by the separation mesh cylinder, the sewage flows into the inside of the packing mesh box through the guide pipe on the guide bucket. When the sewage flows through the clean water packing inside the packing mesh box, the fine impurities in the sewage are further intercepted, and the filtered sewage is discharged through the clean water pipe.

[0026] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects:

[0027] First, the device of the present invention has a reasonable structural design. By performing sedimentation, impurity separation and fine filtration on municipal sewage, it not only improves the device's emergency treatment capability for municipal sewage, but also helps to improve the treatment effect of municipal sewage, thereby improving the safety of municipal sewage discharge.

[0028] Secondly, the present invention uses a conical hopper inside the sedimentation tank to reduce the flow velocity of municipal sewage when it enters the sedimentation tank, thereby reducing the impact of municipal sewage on the sedimentation tank. Furthermore, multiple interlocking isolation sleeves are set at the bottom of the conical hopper. As the municipal sewage passes through the flow channels on each isolation sleeve in sequence, the residence time of the municipal sewage in the sedimentation tank is extended, thereby improving the sedimentation effect of the municipal sewage and ensuring the operational stability of the device.

[0029] Third, this invention utilizes a separation component to separate fine impurities in municipal sewage, and the separated impurities can be discharged from the device under the action of the separation spiral. At the same time, the moving sleeve drives the flushing nozzle to move outside the separation screen cylinder to flush the pollutants adsorbed on the separation screen cylinder, ensuring the reliable operation of the separation screen cylinder and improving the ease of maintenance of the device.

[0065] like Figure 1 As shown, it also includes a PLC controller (commercially available product) mounted on the base 1. A liquid level sensor is installed inside the sedimentation tank 20. The PLC controller is electrically connected to the liquid level sensor, the sewage pump 21, the rotary motor 33 and the stirring motor 43 respectively.

[0066] In this embodiment, the liquid level sensor adopts a product with existing technology, such as the 2088 housing-integrated liquid level gauge produced by Beijing Huakong Xingye Technology Development Co., Ltd.

[0067] Example 9

[0068] This embodiment describes a modular combined municipal sewage emergency treatment method, based on a modular combined municipal sewage emergency treatment device of Embodiment 8, including the following steps:

[0069] S1. Connect the inlet pipe 200 to the municipal sewage pipe. Municipal sewage enters the sedimentation tank 20 through the inlet pipe 200 and first enters the innermost isolation sleeve 23 under the action of the conical bucket 22. Then, it enters the outer isolation sleeve 23 through the flow groove 230 on the innermost isolation sleeve 23. During this process, large particles of impurities with a particle size of 5-8mm in the municipal sewage settle between the bottom of each isolation sleeve 23.

[0070] S2. When the level sensor detects that the sewage level inside the sedimentation tank 20 has reached the set value, the sewage pump 21 is started by the PLC controller. The sewage pump 21 pumps the settled sewage inside the sedimentation tank 20 into the separation screen cylinder 31. Impurities in the sewage are trapped inside the separation screen cylinder 31. Then, the rotary motor 33 is started by the PLC controller. The rotary motor 33 drives the separation spiral 32 to rotate. During the rotation of the separation spiral 32, the impurities trapped inside the separation screen cylinder 31 move to the right side of the separation screen cylinder 31. At this time, the movable baffle 311 moves to the right along the separation screen cylinder 31 under the squeezing action of the impurities. After the pollutants inside the separation screen cylinder 31 are cleaned, the separation screen cylinder 31 can automatically reset under the action of the damping spring 313, and the impurities can be discharged through the slag discharge pipe 302.

[0071] S3. After being separated by the separating screen 31, the wastewater enters the guide hopper 34 and is evenly dispersed into the packing mesh box 41 through the outlets 342 on the horizontal pipes 341 at the bottom of each guide pipe 340. When the wastewater flows through the clean water packing inside the packing mesh box 41, the fine impurities in the wastewater are further intercepted. Then, sodium hypochlorite solution is added to the filtered wastewater through the dosing pipe 402 for disinfection. The stirring motor 43 is started by the PLC controller, which drives one of the stirring rods 42 to rotate. At this time, all the stirring rods 42 rotate simultaneously under the meshing action of the connecting gears 420, so that the sodium hypochlorite solution and the wastewater are mixed more evenly. The disinfected wastewater is discharged through the clean water pipe 400. The volume concentration of the sodium hypochlorite solution is 15%, and the addition ratio is 3 mg / L.

[0072] S4. When it is necessary to clean the pollutants settled inside the sedimentation tank 20, the lifting winch 24 is started by controlling the PLC controller. Under the action of the lifting winch 24, the hoist 240 pulls the conical bucket 22 and the isolation sleeve 23 upward along the inner wall of the sedimentation tank 20. Then, the pollutants settled inside the sedimentation tank 20 can be cleaned through the cleaning pipe 201.

[0073] S5. When it is necessary to clean the separation screen cylinder 31, connect the telescopic hose to the external water source. Since the second pulley 320 and the first pulley 3530 are connected by belt drive, the separation screw 32 can drive the drive screw 353 to rotate when it rotates. The moving sleeve 35 moves along the guide rod 354 under the connection of the threaded seat 351 and the drive screw 353. The flushing nozzle 350 inside the moving sleeve 35 is used to flush the pollutants adsorbed on the separation screen cylinder 31.
