Description

Technical Field

[0001] The invention relates to the technical field of sewage drainage, and in particular discloses a multi-channel drainage device for glow cracking sewage treatment. Background Art

[0002] The glow pyrolysis wastewater treatment equipment is an advanced oxidation equipment based on plasma technology. It excites air or water molecules in the reaction chamber through a high-voltage electric field (10-50kv) to produce high-energy active substances, thereby efficiently degrading difficult-to-degrade organic matter, killing microorganisms and decomposing microplastics. It is mainly used in high-difficulty scenarios such as pharmaceutical wastewater, electronic wastewater, textile wastewater and industrial hazardous waste. The effluent from the glow pyrolysis wastewater treatment equipment can be directly reused or discharged in compliance with standards. It is particularly suitable for industrial parks and pharmaceutical companies with strict requirements on water quality.

[0003] The utility model with application announcement number: CN210559564U discloses a novel drainage device for chemical sewage treatment. The prior art is provided with a sewage outlet for discharging sewage. The sewage in the sewage pool can be discharged through the sewage outlet, thereby achieving the purpose of sewage drainage. The invention with application announcement number: CN108911067A discloses a medical sewage disinfection discharge drainage device. The prior art is provided with a connecting pipe and a drainage pipe. The sewage and the medicine solution can be stirred and mixed by setting a stirring shaft, and the mixed solution is caused to flow into the connecting pipe by controlling the first support plate and the second support plate, so that it is discharged from the drainage pipe.

[0004] The drainage structures disclosed in the prior art are all single-channel drainage structures, and the drainage channel can only drain sewage with a single NTU value. The NTU value is the turbidity parameter of sewage. If the sewage contains a large amount of silt and large particles of impurities, the NTU value of the sewage will be in a higher range. Since the glow cracking wastewater treatment equipment has relatively strict requirements on the NTU value of sewage, it is necessary to control the NTU value of sewage below 50NTU. If the NTU value of sewage is high, it will cause the treatment efficiency of the glow cracking equipment to decrease by 30%-60%, increase energy consumption by 20%-30%, and significantly shorten the life of the equipment; therefore, it is necessary to pre-treat the sewage in advance, and the NTU value of the sewage can be effectively reduced by adding a coagulant. If the glow cracking wastewater treatment equipment adopts the single-channel drainage structure in the above-mentioned prior art, the sewage enters the drainage device through a single channel and flows out through a single channel, which is difficult to adapt to different water qualities (such as high-concentration pharmaceutical wastewater and low-concentration domestic sewage). After mixing, the active sites of the catalyst may be wrapped by suspended matter, causing the TOC removal rate to decrease by 20%-40%, affecting the treatment efficiency of the glow cracking wastewater treatment equipment; and if the amount of coagulant added is too high, it is very easy to cause equipment failure (such as electrode ablation, pipeline blockage), which will directly lead to production suspension in severe cases, increase operation and maintenance costs, and increase the comprehensive operating costs by 25%-40%.

The first and second liquid delivery pipes 14 and 15 are both connected to the liquid inlet pipeline of the glow cracking sewage treatment equipment, so as to deliver the sewage in the upper layers of the first and second sewage treatment tanks 11 and 12 to the glow cracking sewage treatment equipment. The first liquid delivery pipe 14 and the second liquid delivery pipe 15 are respectively fixedly installed with an eleventh solenoid valve 67 and a twelfth solenoid valve 68, which can be used to control the flow of the first liquid delivery pipe 14 and the second liquid delivery pipe 15. The second drain pipe 65 and the third drain pipe 66 are respectively fixedly installed with a thirteenth solenoid valve 69 and a fourteenth solenoid valve 70 at the liquid outlet ports, so as to discharge the sediment at the bottom of the first sewage treatment tank 11 and the second sewage treatment tank 12.

[0030] The working principle of the present invention is: The sewage generated by the industrial park and enterprises can enter the sedimentation barrel 3 through the water inlet pipe 4. By starting the first motor 23, the rotating rod 20 and the propeller impeller 21 can be rotated together, and under the cooperation of the propeller blade 24, the sewage in the sedimentation barrel 3 is rotated and separated, so that the large particles of impurities in the sewage are precipitated to the bottom of the sedimentation chamber 19, and the sewage in the upper layer of the upper floating chamber 18 can be sent to the separation barrel 7 through the outlet pipe 5. The turbidity sensor 8 can detect the NTU value of the sewage in the separation barrel 7 in real time; if the NTU value of the sewage in the separation barrel 7 is greater than the standard value, the third solenoid valve 33 allows the sewage in the separation barrel 7 to enter the first separation pipe 9 and introduce it into the first sewage treatment tank 11; if the NTU value of the sewage in the separation barrel 7 is less than the standard value, the sewage in the separation barrel 7 is introduced into the second sewage treatment tank 12 through the second liquid delivery pipe 15. The large particles of impurities and sewage at the bottom of the separation barrel 7 can flow into the drainage box 40 through the guide pipe 6, and through the screening effect of the screening box 45, the large particles of impurities are isolated, allowing the sewage to enter the interior of the buffer box 37; the sewage is further precipitated in the buffer box 37, and the small particles of impurities mixed in the sewage are precipitated to the bottom of the buffer box 37, and the upper sewage can be jointly merged into the confluence pipe 53 through the first infusion pipe 49 and the second infusion pipe 50, thereby entering the first sewage treatment tank 11.

[0031] At this time, the NTU value of the sewage in the first sewage treatment tank 11 and the second sewage treatment tank 12 can be fed back in real time through the NTU value sensor 58, so as to cooperate with the ninth solenoid valve 62 and the tenth solenoid valve 63 to further control the flow rate of the coagulant in the first shunt pipe 60 and the second shunt pipe 61, so as to input an appropriate amount of coagulant into the first sewage treatment tank 11 and the second sewage treatment tank 12, so as to perform coagulant treatment on the sewage in the first sewage treatment tank 11 and the second sewage treatment tank 12, promote the condensation of fine particles without edema into flocs, and make them quickly precipitate to the bottom of the first sewage treatment tank 11 and the second sewage treatment tank 12, and make the NTH value of the sewage at the top of the first sewage treatment tank 11 and the second sewage treatment tank 12 within the range specified by the glow cracking sewage treatment equipment, and respectively inject the sewage in the upper layer of the first sewage treatment tank 11 and the second sewage treatment tank 12 into the glow cracking sewage treatment equipment through the first liquid delivery pipe 14 and the second liquid delivery pipe 15, so as to facilitate the glow cracking sewage treatment equipment to perform deep treatment on the sewage.

[0032] In the above-mentioned sewage treatment process, the flow rate of sewage in the water inlet pipe 4 is proportional to the flow rate of sewage in the first liquid delivery pipe 14 and the second liquid delivery pipe 15, and is achieved through the cooperation of the first solenoid valve 28 and the eleventh solenoid valve 67 and the twelfth solenoid valve 68; at the same time, the turbidity sensor 8 and the NTU numerical sensor 58 detect the sewage parameters in real time, so as to facilitate the control of the added volume of the coagulant, make full use of the coagulant ability of the coagulant, avoid injecting too much coagulant into the first sewage treatment tank 11 and the second sewage treatment tank 12, ensure that the wastewater output by the first liquid delivery pipe 14 and the second liquid delivery pipe 15 is not doped with excessive coagulant, and ensure the long-term normal operation of the glow cracking sewage treatment equipment.
