Description

Technical Field

[0001] The invention relates to the technical field of water quality detection, and in particular to a magnetic coagulation and high-efficiency sedimentation integrated sewage treatment equipment. Background Art

[0002] Magnetic coagulation is a technology based on heavy medium loading sedimentation technology. It uses conventional flocculation sedimentation method to increase the settling rate of flocs by adding highly efficient and recyclable magnetic powder in the coagulation stage, and uses sludge return device to improve the coagulation reaction effect. Due to its good treatment effect, it has been widely used in the field of water treatment in recent years.

[0003] However, during the coagulation reaction stirring process, there are three ways to input magnetic powder. One is to pump in new magnetic powder, one is to return the magnetic powder directly to the coagulation chamber after being discharged from the sludge pool, and the other is to let the magnetic powder separated by the magnetic mud separator fall into the top. This process can realize the recycling of magnetic powder with high efficiency. However, due to the presence of the agitator during the stirring and coagulation, the magnetic powder entering from the bottom cannot be fully mixed with the raw water, resulting in a waste of magnetic powder. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a magnetic coagulation and high-efficiency sedimentation integrated sewage treatment equipment with high magnetic powder utilization and high coagulation efficiency.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A magnetic coagulation and high-efficiency sedimentation integrated sewage treatment equipment comprises a coagulation unit and a clarification tank, wherein the coagulation unit comprises a PAC dosing tank, a magnetic powder dosing tank and a PAM dosing tank arranged accordingly, wherein the upper ends of the PAC dosing tank and the magnetic powder dosing tank are connected, the lower ends of the magnetic powder dosing tank and the PAM dosing tank are connected, the lower end of the PAM dosing tank is connected and connected with the upper end of the clarification tank, the PAC dosing tank, the magnetic powder dosing tank and the PAM dosing tank are all provided with stirring components, the magnetic powder dosing tank is respectively connected with a magnetic powder input component, a magnetic powder separator and a magnetic powder pre-recovery device, and a sludge sewage discharge component is arranged in the clarification tank, The sludge sewage discharge component is respectively connected to the magnetic powder input component, the magnetic powder separator and the magnetic powder pre-recovery device through the sewage discharge component. The magnetic powder input component includes input pipes evenly arranged at the edge of the magnetic powder addition pool. The middle part of the input pipe is a telescopic hose. The input pipe is connected to the telescopic mechanism of the side wall. The bottoms of multiple input pipes are connected and pass through the input main pipe outward. The input main pipe is also connected to the magnetic powder bin. A turbidity detection component is arranged on the top of the magnetic powder bin. The magnetic powder outlet of the magnetic powder separator is located at the top of the magnetic powder addition pool. The outlet of the magnetic powder pre-recovery device is arranged in the middle of the magnetic powder addition pool.

[0007] In this way, the raw water passes through the PAC dosing tank, the magnetic powder dosing tank and the PAM dosing tank at one time, and enters the clarification tank, where it settles quickly. The magnetic sludge is separated by the sludge discharge component, and the clear liquid on the top is discharged. The discharged magnetic sludge is distributed by the discharge component and distributed to the magnetic powder input component, the magnetic powder pre-recovery device and the magnetic powder separator according to the dynamically adjusted ratio. The magnetic sludge separation rates of the three are small to large. The magnetic sludge of the treated magnetic powder input component directly re-enters, the magnetic powder pre-recovery device enters through the middle after simple treatment, and the magnetic powder separator enters from the top after thorough separation, which can greatly improve the utilization of magnetic powder and improve sedimentation efficiency. The turbidity detection component is used to detect the turbidity of the upper water liquid and determine the distribution ratio of the three. The more turbid it is, the greater the proportion of the magnetic powder input component, because the separation of the magnetic separator requires time to wait, so that the magnetic powder can enter quickly to ensure the efficiency of coagulation. The lifting component can drive the lifting and lowering of the input pipe to avoid entering from the bottom and affecting the use effect of the magnetic powder.

[0008] As an optimization, the stirring components all include a first driving motor arranged at the top, the first driving motor is provided with a stirring shaft downward, the stirring shaft is provided with a stirring blade, and the end of the stirring blade makes way with the input pipe.

[0009] In this way, rapid coagulation can be achieved while providing installation and lifting space for the input pipe to ensure that new magnetic powder and magnetic mud can quickly come into contact with the liquid.

[0010] As an optimization, a shearing component is provided in the through-hole of the magnetic powder pre-recovery device.

[0011] In this way, the primary separation of magnetic mud can be achieved through rapid shearing, ensuring that magnetic powder can be replenished in a short time.

[0012] As an optimization, the sludge discharge assembly includes a scraper plate arranged at the bottom of the clarifier, the scraper plate is transmission-connected to the second drive motor, and a sludge discharge hole is arranged at the bottom of the clarifier.

[0013] In this way, the magnetic sludge settled in the clarification tank can be discharged quickly and its utilization efficiency can be guaranteed without causing accumulation.

[0014] As an optimization, an inclined plate assembly is provided on the top of the clarification tank, and the upper clear liquid is discharged through overflow.

[0015] In this way, cement separation can be achieved and discharged promptly and quickly, and the inclined plate acts as a mud barrier to ensure the stability of the discharged clear liquid.

[0016] As an optimization, the sewage discharge component is three sludge slurry pumps, and the sludge slurry pumps are all connected to the mud discharge hole.

[0017] In this way, the sludge slurry pump has wear-resistant performance, ensuring its service life, and can also perform the function of magnetic mud distribution by controlling the flow rate.

[0018] As an optimization, the telescopic assembly is a cylinder fixedly mounted on the side wall of the magnetic powder dosing tank.

[0019] In this way, the input tube can be precisely regulated and can be used for a long time.

[0020] As an optimization, a feeding pump is provided outwardly of the magnetic powder bin.

[0021] In this way, the magnetic powder can be replenished in time to ensure the coagulation effect. BRIEF DESCRIPTION OF THE DRAWINGS
