Description

Technical Field

[0001] The present invention relates to the technical field of sludge treatment, and particularly to a magnetic field eddy current sludge and manure treatment system and process. Background Art

[0002] The treatment of sludge and livestock manure is a very important part of modern environmental governance. The main purpose is to comprehensively utilize domestic sludge and livestock manure resources, reduce operating costs, and reduce environmental pollution. Sewage treatment usually includes three stages: primary, secondary, and tertiary treatment. Primary treatment mainly removes large particulate matter through sedimentation tanks. Secondary treatment usually uses biological treatment methods (such as activated sludge method, oxidation ditch method, etc.) to remove dissolved organic matter and suspended solids. Tertiary treatment further removes harmful substances in water through chemical methods or membrane filtration technology to make the water quality meet the discharge standard or reuse standard. Sludge treatment is an important part that cannot be ignored in the sewage treatment process. The amount of sludge generated is large and contains a large amount of harmful substances. Improper treatment will cause serious secondary pollution. Common sludge treatment methods include concentration, dehydration, drying, and incineration. Through these methods, the volume of sludge can be greatly reduced, and energy can be recovered or converted into harmless substances through incineration or anaerobic digestion.

[0003] The invention with the authorized announcement number CN112759083B discloses a sludge source reduction device and a sludge source reduction process. This invention realizes the effective separation of microorganisms in the biological selector by setting inlet and outlet sludge ports at different heights. It has a simple structure, low equipment cost, realizes sludge source reduction, improves the efficiency of sludge treatment and disposal, and reduces the treatment and disposal costs of sludge.

[0004] The above device can achieve the purpose of treating sewage sludge. By inhibiting the growth of microorganisms, the growth rate of microorganisms and the amount of biological solids are reduced, resulting in less solid waste generated, which is convenient for treating sewage sludge. However, the above device can only reduce the generation of solid waste and does not have relevant mechanisms for utilizing solid waste. Therefore, a sludge treatment system and process for treating sewage sludge are needed. Summary of the Invention

At the discharge outlet of the liquid detection tank, a three-way solenoid valve is arranged. Behind the three-way solenoid valve, a collection tank is arranged. On one side of the three-way solenoid valve, a third water pump is arranged. One discharge outlet of the three-way solenoid valve is communicated with the collection tank through a pipeline, and the other discharge outlet of the three-way solenoid valve is connected with the feed inlet of the third water pump through a pipeline. The discharge outlet of the third water pump is communicated with the mixing tank through a return pipe.

[0007] As a further scheme of the present invention: The chemical agent adding device includes a chemical agent storage tank, in which a chemical agent pump is arranged. Above the chemical agent storage tank, a chemical agent inlet pipe is arranged. The temporary storage tank is communicated with the chemical agent storage tank through a chemical agent discharge pipe, and a second solenoid valve is arranged on the chemical agent discharge pipe.

[0008] As a still further scheme of the present invention: The magnetic field eddy current treatment device includes a first outer shell, above which a control box is arranged, and below which an armored temperature measuring element is arranged. Through holes are opened at the upper and lower ends of the first outer shell, and an outer sleeve pipe is penetrated through the through holes. A cylindrical magnetic conductive workpiece is fixedly arranged inside the outer sleeve pipe. A stator assembly is arranged on one side of the first outer shell close to the outer sleeve pipe. A rotor is arranged corresponding to the stator assembly inside the cylindrical magnetic conductive workpiece. Connecting pipe assemblies are respectively arranged at both ends of the outer sleeve pipe. The temporary storage tank is connected with the connecting pipe assembly at the upper part through a first sewage feed pipe. Below the connecting pipe assembly at the lower part, a second sewage discharge pipe is arranged, and the outer end of the second sewage discharge pipe is communicated with the filter press. A heat dissipation device is arranged on the right side of the first outer shell. The heat dissipation device includes a coolant storage tank, above which a first water pump is arranged. The first outer shell is communicated with the first water pump through a coolant inlet pipe, and the first outer shell is communicated with the coolant storage tank through a coolant outlet pipe. An inlet valve is arranged on the coolant inlet pipe, and an outlet valve is arranged on the coolant outlet pipe.

[0009] As a further solution of the present invention: The heat dissipation device further includes a second water pump, which is arranged above the coolant storage tank. An exchanger is arranged above the second water pump. One end of the exchanger is communicated with the water outlet of the second water pump, and the other end is communicated with the coolant storage tank. Above the coolant storage tank and outside the exchanger, a second outer casing is arranged. An air inlet is fixedly arranged at the bottom of the second outer casing. A fan is arranged above the exchanger in the middle of the top plate of the second outer casing.

[0010] As a further solution of the present invention: A number of fins are evenly arranged on the exchanger.

[0011] A process for implementing the above magnetic field eddy current sludge and manure treatment system includes the following steps: Step 1: Collect sewage, sludge and manure with a water content of 98% into a mixing tank, and the mixing mechanism in the mixing tank mixes the sewage, sludge and manure. Step 2: The transfer pump transports the evenly mixed sewage, sludge and manure to the temporary storage tank through a pipeline, and the medicament in the medicament storage tank is added to the temporary storage tank through a pipeline. Step 3: The sewage, sludge and manure after adding the medicament are transported to the magnetic field eddy current treatment device, and the heat dissipation device dissipates heat from the magnetic field eddy current treatment device. Step 4: The treated sewage, sludge and manure are fed into a filter press. After being filtered by the filter press, the solid sludge is discharged externally through the solid discharge pipe, and the filtered sewage is transported to the liquid detection tank through the liquid discharge pipe. Step 5: The water quality detection sensor detects the sewage. If it meets the standard, it is transported to the collection tank through the three-way solenoid valve. If it does not meet the standard, it is refluxed to the mixing tank through the return liquid pipe.

[0012] As a further solution of the present invention: The medicament in Step 2 is lime milk.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The sewage, sludge and manure in the mixing tank are transported to the temporary storage tank through the transfer pump, and the medicament adding device adds water treatment additives to the temporary storage tank, which is convenient for the magnetic field eddy current treatment device to treat the sewage, sludge and manure. The heat dissipation device dissipates heat from the magnetic field eddy current treatment device, enabling the magnetic field eddy current treatment device to treat the sewage, sludge and manure with the highest efficiency. The filter press separates the solid and liquid of the treated sewage, sludge and manure. The water quality detection sensor detects the filtered sewage. If the detection is qualified, it is fed into the collection tank through the three-way solenoid valve. If the detection is unqualified, it is transported back to the mixing tank through the third water pump and the return liquid pipe, improving the purification effect of the sewage and sludge. The armored temperature measuring element can measure the real-time temperature data inside the first outer shell to provide feedback on the overall operation status of the equipment. The operator can adjust the circulation flow rate of the cooling medium based on the temperature data, thereby improving the practicality of the device. The ferromagnetic elements (rotors) of different lengths in the magnetic field eddy current treatment device, under the action of the rotating electromagnetic field, form a circuit in a short period of time and then quickly disconnect, generating a strong current and a large number of micro-arcs. The ferromagnetic elements move rapidly in the working area and form an eddy current layer. The polarity of the ferromagnetic element electrodes is reversed (repeated magnetization). The cavitation effect generated by the high-speed rotation of the ferromagnetic elements in the fluid continuously generates pulse shocks, powerful hydrodynamic shocks, large shear stress in the fluid, developed turbulence, and pressure pulses. The structure of the cell wall is continuously destroyed under the action of the pressure pulse, effectively eliminating pathogenic plant microorganisms, viruses, bacteria, grass seeds and insect eggs. The entire process is fast and thorough, thereby effectively treating sewage sludge. The coolant in the coolant storage tank is pumped into the heat exchanger by the second water pump, and the fan dissipates heat from the heat exchanger, thereby dissipating heat from the coolant, thereby maintaining high-efficiency operation of the magnetic field eddy current processing device.
