[0066] (S01) After the washing pool in the experimental park cleans the experimental equipment, washing wastewater is generated. The washing wastewater flows into the flow limiting frame along the sewage pipe. Acid-base regulating liquid is added to the washing wastewater in the flow limiting frame to adjust the pH value of the washing wastewater. At the same time, the inflow speed and temporary storage volume of the washing wastewater are controlled until the preset water volume is reached and the acid-base balance is achieved. Then, the control valve is opened to allow the washing wastewater to enter the coagulation and sedimentation frame. Calibration and maintenance are performed every week to avoid deviations in the washing wastewater regulation.

[0067] The present invention achieves accurate regulation of the pH of the washing wastewater by accurately adding the acid-base regulating liquid into the flow limiting frame and controlling the inflow speed and temporary storage volume of the washing wastewater, thereby creating a stable and suitable chemical environment for subsequent treatment, and at the same time ensuring that the washing wastewater has a suitable amount of water and stable water quality when entering the next process, thereby avoiding the impact of water quality and water quantity fluctuations on subsequent treatment links, and improving the stability and reliability of the entire treatment process;

[0068] (S02) After the washing wastewater enters the coagulation and sedimentation frame, calcium chloride solution, polyaluminium chloride solution and polyacrylamide solution are added, and the washing wastewater is fully mixed with the reagent to promote the coagulation reaction of suspended matter and colloid, accelerate the sedimentation process, improve the coagulation and sedimentation effect, check the operation status every week, repair or replace damaged parts in time to ensure its normal operation;

[0069] The present invention greatly enhances the coagulation ability of suspended matter and colloids and accelerates the precipitation process by synergistically adding multiple agents and fully mixing them with washing wastewater, so that solid impurities in washing wastewater can be separated from water more efficiently, significantly improving the clarity and purity of washing wastewater and reducing the load of subsequent treatment;

[0070] (S03) After sedimentation, the sludge is deposited at the bottom of the coagulation sedimentation frame, the supernatant flows out through the effluent weir and enters the ozone reaction column, and the bottom sludge is discharged to the sludge concentration tank through the sludge discharge pipe. The sludge in the sludge concentration tank is cleaned every week to prevent sludge seepage and secondary pollution;

[0071] The present invention successfully separates the sludge from the supernatant through the sedimentation process, and the sludge is discharged to the sludge concentration tank through the sludge discharge pipe, thereby avoiding the accumulation of sludge in the reaction system and providing convenient conditions for the centralized treatment of sludge; the supernatant stably flows out through the outlet weir and enters the ozone reaction column, thereby ensuring that the inlet water quality of the subsequent treatment link is stable and uniform, avoiding the influence of water flow fluctuation or uneven water quality on the ozone oxidation effect, providing a stable inlet water condition for the ozone oxidation reaction, and facilitating the improvement of the efficiency and effect of ozone oxidation;

[0072] (S04) The ozone generator generates ozone, which is fully contacted with the washing wastewater in the ozone reaction column to oxidize the organic matter, bacteria and viruses in the washing wastewater and enhance the biodegradability of the washing wastewater. The excess ozone is discharged after being treated by the ozone destroyer. The oxidized washing wastewater enters the intermediate water tank through the diversion pipe. The ozone generator and ozone destroyer are maintained weekly to ensure that the ozone generation amount is appropriate and the concentration is stable to prevent ozone leakage from endangering the environment and personnel safety;

[0073] The present invention fully contacts the washing wastewater with ozone generated by the ozone generator in the ozone reaction column, effectively oxidizes organic matter, bacteria and viruses in the washing wastewater, significantly reduces the chemical oxygen demand (COD) and biological oxygen demand (BOD) of the washing wastewater, enhances the biodegradability of the washing wastewater, creates favorable conditions for subsequent biological treatment links, improves the treatability and purification degree of the washing wastewater, and reduces the potential harm of harmful substances in the wastewater to the environment;

[0074] (S05) The domestic sewage generated in the experimental park first enters the septic tank, where it undergoes multi-stage anaerobic fermentation and sedimentation treatment to decompose organic matter in the sewage, kill pathogens and parasite eggs, and the treated domestic sewage enters the intermediate water tank and mixes with the washing wastewater. It is then transported to the three-phase separation barrel by a diaphragm pump, where it undergoes anaerobic hydrolysis and acidification reactions, and the washing wastewater is circulated by a circulating pump to promote the decomposition of large molecular organic matter into small molecular organic matter, achieving the three-phase separation of water, air and mud. The septic tank is cleaned and maintained every week to ensure the stability of the domestic sewage treatment effect and avoid sewage overflow and pollution spread;

[0075] The present invention uses a septic tank component to treat domestic sewage through multi-stage anaerobic fermentation and precipitation, effectively decomposes organic matter in domestic sewage, kills pathogens and parasite eggs, reduces the pollution level and biological hazard of domestic sewage, and enables it to be safely and stably mixed with washing wastewater for subsequent joint treatment, reflecting the adaptability and treatment capacity for complex sewage components; the present invention realizes the three-phase separation of water, gas and mud in a three-phase separation barrel, which is not only conducive to the further treatment of wastewater, but also creates conditions for the recycling of energy materials such as biogas, improves the utilization rate of resources, and reduces the discharge of waste. At the same time, the wastewater is circulated through a circulating pump, which promotes the decomposition of macromolecular organic matter, improves the biodegradability of wastewater, and provides better quality influent for subsequent biological treatment;

[0076] (S06) The washing wastewater is pumped from the three-phase separation barrel to the water inlet pipe by a self-priming pump, and then evenly distributed through the central pipe and the reflector plate to enter the anaerobic sedimentation frame for sedimentation. The sludge is precipitated at the bottom and discharged to the sludge concentration tank through the sludge discharge pipe. The self-priming pump and anaerobic sedimentation frame are checked weekly to clean up the debris and sludge to ensure the smooth sedimentation process and avoid interruption of the washing wastewater treatment process;

[0077] In the present invention, the washing wastewater is pumped by a self-priming pump and evenly distributed through a central pipe and a reflector plate before entering the anaerobic precipitation frame, thereby ensuring a uniform flow state of the washing wastewater, avoiding the problem of poor precipitation effect caused by excessively fast or slow local water flow, improving the efficiency and quality of sludge precipitation, making the anaerobic precipitation process more stable and efficient, reducing the content of suspended matter and organic matter in the wastewater, and reducing the burden on subsequent treatment;

[0078] (S07) The self-priming pump pumps the washing wastewater after anaerobic precipitation to the anoxic reaction tank. The oily wastewater generated in the experimental park is also treated by the oil separation component and enters the anoxic reaction tank to mix with the washing wastewater. In the anoxic environment, the washing wastewater is further treated by microorganisms to remove organic matter and nitrogen and phosphorus pollutants therein. The oil separation component is cleaned every week to prevent grease accumulation from affecting the oil separation effect;

[0079] The present invention pumps the washing wastewater after anaerobic precipitation to the anoxic reaction tank through a self-priming pump, and mixes it with the oily wastewater treated by the oil separation component, thereby realizing the coordinated treatment of different types of wastewater, making full use of the metabolic capacity of anoxic microorganisms, effectively removing organic matter and nitrogen and phosphorus pollutants in the wastewater, improving the comprehensive treatment capacity and resource utilization rate of the wastewater treatment system, avoiding the problems of repeated equipment investment and low treatment efficiency caused by separately treating different wastewaters, and reducing the wastewater treatment cost and floor space.

[0080] (S08) The diaphragm pump transports the washing wastewater after the facultative aerobic treatment to the aerobic frame, and the aeration pump fills air into the washing wastewater in the aerobic frame through the aeration plate to provide sufficient oxygen for aerobic microorganisms to fully decompose the organic matter in the washing wastewater and further purify the washing wastewater. The treated washing wastewater enters the membrane bioreactor frame, and the aeration parameters are adjusted every week according to the growth status of the microorganisms to ensure that the aerobic treatment effect is stable and efficient, and to ensure that the washing wastewater is effectively purified;

[0081] The present invention transports the wastewater after anoxic treatment to the aerobic frame through a diaphragm pump, and the aeration pump fills air through an aeration plate, providing sufficient oxygen for aerobic microorganisms, enabling them to fully decompose organic matter in the wastewater, thereby improving the purification degree of the washing wastewater, making the wastewater closer to the discharge standard, and reducing the risk of pollution to the environment by harmful substances in the washing wastewater.

[0082] (S09) In the membrane bioreactor framework, the remaining suspended solids, colloids and microbial pollutants in the washing wastewater are intercepted by the filtering effect of the membrane, the membrane pollution is reduced by the aeration effect of the aeration pipe and the fan, the membrane flux and filtering performance are maintained, the treated washing wastewater is pumped to the monitoring framework by the suction pipe and the suction pump, and the membrane is cleaned every week to ensure that the effluent water quality continues to improve;

[0083] The present invention effectively intercepts the remaining suspended solids, colloids and microbial pollutants in the wastewater through the filtering effect of the membrane, and further improves the effluent water quality. The aeration effect of the aeration pipe and the fan reduces membrane pollution, maintains membrane flux and filtering performance, prolongs the service life of the membrane, reduces the frequency and cost of membrane replacement, and ensures the stable and efficient operation of the membrane bioreactor assembly.

[0084] (S10) The monitoring framework mixes the washing wastewater evenly and performs real-time monitoring and analysis on various indicators of the washing wastewater. If the water quality meets the standard, it will be discharged to ensure that the final effluent water quality meets the discharge standard.

[0085] After the washing wastewater is evenly mixed through the monitoring framework, the present invention conducts real-time monitoring and analysis on various indicators of the washing wastewater, accurately determines whether the washing wastewater meets the standards, and ensures that only the washing wastewater that meets the emission standards is discharged, thereby ensuring environmental quality and ecological safety, and achieving the ultimate goal of washing wastewater treatment. At the same time, it provides data support for quality control and optimization of the washing wastewater treatment process, which helps to further improve operating efficiency and treatment effects.

[0185] The experimental park washing wastewater treatment method comprises the following steps:

[0186] (S01) After the washing pool 200 in the experimental park cleans the experimental equipment, washing wastewater is generated. The wastewater flows into the flow limiting frame 302 along the sewage pipe 301. Acid-base regulating liquid is added to the wastewater in the flow limiting frame 302 to adjust the pH value of the wastewater. At the same time, the inflow speed and temporary storage volume of the wastewater are controlled until the preset water volume is reached and the acid-base balance is achieved. Then, the control valve 303 is opened to allow the washing wastewater to enter the coagulation and sedimentation frame 401. Calibration and maintenance are performed every week to avoid deviations in wastewater regulation.

[0187] (S02) After the wastewater enters the coagulation and sedimentation frame 401, calcium chloride solution, polyaluminium chloride solution and polyacrylamide solution are added, and the wastewater and the reagent are fully mixed to promote the coagulation reaction of suspended matter and colloid, accelerate the sedimentation process, improve the coagulation and sedimentation effect, check the operation status weekly, repair or replace damaged parts in time to ensure its normal operation;

[0188] (S03) After sedimentation, the sludge is deposited at the bottom of the coagulation sedimentation frame 401, and the supernatant flows out through the effluent weir 4014 and enters the ozone reaction column 503. The bottom sludge is discharged to the sludge concentration tank 1300 through the first sludge discharge pipe 409. The sludge in the sludge concentration tank 1300 is cleaned every week to prevent sludge seepage and secondary pollution;

[0189] (S04) The ozone generator 506 generates ozone, which is fully contacted with the washing wastewater in the ozone reaction column 503, oxidizing the organic matter, bacteria and viruses in the wastewater, and enhancing the biodegradability of the wastewater. The excess ozone is discharged after being treated by the ozone destroyer 505, and the oxidized wastewater enters the intermediate water tank 600 through the fourth guide pipe 504. The ozone generator 506 and the ozone destroyer 505 are maintained weekly to ensure that the ozone generation amount is appropriate and the concentration is stable, so as to prevent ozone leakage from endangering the environment and personnel safety;

[0190] (S05) The domestic sewage generated in the experimental park first enters the septic tank assembly 1400, and undergoes multi-stage anaerobic fermentation and sedimentation treatment in the septic tank assembly 1400 to decompose organic matter in the sewage, kill pathogens and parasite eggs, and the treated domestic sewage enters the intermediate water tank 600 to mix with washing wastewater, and is then transported to the three-phase separation barrel 703 by the second diaphragm pump 701, and an anaerobic hydrolysis and acidification reaction is carried out in the three-phase separation barrel 703, and the wastewater is circulated by the circulation pump 7032 to promote the decomposition of large molecular organic matter into small molecular organic matter, and realize the three-phase separation of water, gas and mud. The septic tank assembly 1400 is cleaned and maintained every week to ensure the stable treatment effect of domestic sewage and avoid sewage overflow and pollution spread;

[0191] (S06) The washing wastewater is pumped from the three-phase separation barrel 703 to the water inlet pipe 802 by the first self-priming pump 801, and then evenly distributed through the central pipe 803 and the reflector 804 to enter the anaerobic sedimentation frame 805 for sedimentation. The sludge is precipitated at the bottom and discharged to the sludge concentration tank 1300 through the second sludge discharge pipe 806. The first self-priming pump 801 and the anaerobic sedimentation frame 805 are checked weekly to clean up the debris and sludge to ensure the smooth progress of the sedimentation process and avoid interruption of the wastewater treatment process.

[0192] (S07) The second self-priming pump 901 pumps the washing wastewater after anaerobic precipitation to the anoxic reaction tank 903. The oily wastewater generated in the experimental park is also treated by the oil separator component 1500 and enters the anoxic reaction tank 903 to mix with the washing wastewater. In the anoxic environment, the wastewater is further treated by microorganisms to remove organic matter and nitrogen and phosphorus pollutants therein. The oil separator component 1500 is cleaned every week to prevent grease accumulation from affecting the oil separation effect.

[0193] (S08) The third diaphragm pump 1001 delivers the washing wastewater after the facultative aerobic treatment to the aerobic frame 1003. The aeration pump 1005 injects air into the washing wastewater in the aerobic frame 1003 through the aeration plate 10051 to provide sufficient oxygen for aerobic microorganisms to fully decompose organic matter in the wastewater and further purify the wastewater. The treated wastewater enters the membrane bioreactor frame 1101. The aeration parameters are adjusted every week according to the growth status of the microorganisms to ensure that the aerobic treatment effect is stable and efficient, and the wastewater is effectively purified.

[0194] (S09) In the membrane bioreactor frame 1101, the remaining suspended solids, colloids and microbial pollutants in the wastewater are intercepted by the filtering effect of the membrane 1105, and the membrane pollution is reduced by the aeration effect of the aeration pipe 1106 and the fan 1107 to maintain the membrane flux and filtering performance. The treated washing wastewater is pumped to the monitoring frame 1201 by the suction pipe 1102 and the suction pump 1103, and the membrane 1105 is cleaned every week to ensure that the effluent water quality continues to improve;

[0195] (S10) The monitoring framework 1201 mixes the washing wastewater evenly and performs real-time monitoring and analysis on various indicators of the wastewater. If the water quality meets the standard, it will be discharged to ensure that the final effluent water quality meets the discharge standard.

[0228] Example:

[0229] This embodiment takes a certain experimental park as an example. The experimental park includes a scientific research office area and a living supporting area, and is integrated into the local sewage pipe network.

[0230] In this embodiment, the main washing wastewater comes from the hydroacoustic detection research and testing support laboratory, the micro-nano processing laboratory, the materials public support laboratory, the fruit fly larvae research laboratory and the biocomputing experimental laboratory, as well as the domestic sewage generated by the daily life of scientific researchers and the oily wastewater generated in the canteen.

[0231] In this embodiment, during the cleaning process of experimental instruments, the underwater acoustic detection research and test support laboratory generates washing wastewater containing various chemical reagent residues, heavy metal ions and a small amount of organic impurities. The characteristics of the washing wastewater are complex composition and irregular discharge, small one-time discharge but strong intermittent, and the water quality components fluctuate greatly due to the influence of experimental projects and reagents used; due to the particularity of micro-nano processing technology, the washing wastewater of the micro-nano processing laboratory contains tiny particle suspended matter, organic photoresist and some special metal ions, and the wastewater discharge also presents the characteristics of intermittent and small flow, and the purity of water quality is high, which is difficult to handle; the materials public support laboratory involves the testing and processing of various materials, and the wastewater generated contains different types of metal ions, acid-base substances and high molecular polymers, etc. The water quality varies, and the pollutant concentration varies depending on the experimental materials and operation steps; the washing wastewater of the fruit fly larvae research laboratory mainly contains biological metabolites, Organic nutrients and a small amount of disinfectant residues have certain biological contamination, and the discharge time and flow rate of wastewater are related to the experimental cycle and are unstable; the wastewater generated by the biocomputing experimental laboratory contains biological sample residues, buffer components and some organic reagents used for cell culture and experiments. The composition of the wastewater is complex, and the biologically active substances in it need to be properly handled to avoid potential harm to the environment; the sewage generated by the daily life of scientific researchers has water quality components similar to ordinary domestic sewage, mainly containing organic matter, nitrogen and phosphorus compounds, suspended solids and microorganisms, but the amount of sewage is relatively stable and has certain biodegradability, which can be preliminarily treated by conventional biological treatment methods; the wastewater generated by the canteen during the catering processing process contains a large amount of grease, food residues and a certain amount of detergent. The oil content of the wastewater is relatively high. If it is discharged directly, it will cause blockage and pollution to the pipeline and subsequent sewage treatment facilities, and it needs to be treated with oil separation first.

[0232] In this embodiment, the washing wastewater generated by various laboratories is first collected through the sewage pipe 301 and transported to the flow limiting frame 302 of the regulating component. The multiple rotatable flow limiting plates in the flow limiting frame 302 separate and temporarily store the washing wastewater of different time periods and different components according to the data monitored by the flow meter and the acidity and alkalinity information fed back by the pH sensor, and accurately add acid-base regulating liquid to adjust the pH value of the wastewater. At the same time, the inflow speed and temporary storage volume of the wastewater are strictly controlled until the preset water volume is reached and the acid-base balance is achieved, and then the control valve 303 is opened to allow the washing wastewater to stably enter the coagulation and sedimentation frame 401 of the coagulation and sedimentation component.

[0233] In the coagulation and sedimentation frame 401, calcium chloride solution, polyaluminium chloride solution and polyacrylamide solution are added, and the first driver 402 drives the first agitator 403 and the second agitator 405 in the guide tube 404 to fully mix the wastewater and the reagent, so as to promote the coagulation reaction of the suspended matter and the colloid and accelerate the sedimentation process. After the sedimentation, the sludge is deposited at the bottom of the frame and discharged to the sludge concentration tank 901 through the first sludge discharge pipe 406, and the supernatant flows out through the outlet weir 407 and enters the ozone reaction column 501 of the ozone oxidation component.

[0234] In the ozone oxidation component, the ozone generated by the ozone generator 502 is fully contacted with the washing wastewater in the ozone reaction column 501, oxidizing the organic matter, bacteria and viruses in the wastewater and enhancing the biodegradability of the wastewater. The oxygen generator and ozone concentration analyzer integrated in the ozone generator 502 ensure that the ozone generation amount is appropriate and the concentration is stable. The excess ozone is discharged after being treated by the ozone destroyer 503, and the oxidized wastewater enters the intermediate water tank 601 through the diversion pipe.

[0235] The domestic sewage generated in the experimental park first enters the septic tank component, and undergoes multi-stage anaerobic fermentation and precipitation treatment in the first septic tank 701, the second septic tank 702 and the third septic tank 703 to decompose the organic matter in the sewage, kill bacteria and parasite eggs, and the treated domestic sewage enters the intermediate water tank 601 through the sewer pipe 704 to mix with the washing wastewater. Subsequently, it is transported to the three-phase separation tank 802 by the second diaphragm pump 801, and the wastewater is circulated by the circulation pump 803 to promote the decomposition of large molecular organic matter into small molecular organic matter, and realize the three-phase separation of water, gas and mud.

[0236] The mixed wastewater is pumped from the three-phase separation barrel 802 to the water inlet pipe 805 by the first self-priming pump 804, and then evenly distributed through the central pipe 806 and the reflection plate 807 to enter the anaerobic sedimentation frame 808 for sedimentation. The sludge settles at the bottom and is discharged to the sludge concentration tank 901 through the second sludge discharge pipe 809, and the supernatant is pumped to the anerobic reaction tank 1001 by the second self-priming pump 810.

[0237] The oily wastewater generated by the canteen is treated by the oil separation assembly. The separation box 1102 in the oil separation frame 1101 is combined with the multi-layer filter plate to perform multi-stage fine filtration on the oily wastewater. The oil is intercepted and collected in the oil storage box 1105. The wastewater that has undergone preliminary oil separation treatment enters the anoxic reaction tank 1001 through the drainage pipe 1106 and mixes with other wastewater. In the anoxic environment, the wastewater is further treated with microorganisms to remove organic matter and nitrogen and phosphorus pollutants.

[0238] The wastewater after anoxic treatment is transported to the aerobic frame 1202 by the third diaphragm pump 1201. The aeration pump 1203 injects air into the wastewater in the aerobic frame 1202 through the aeration plate 1204, providing sufficient oxygen for aerobic microorganisms to fully decompose organic matter in the wastewater and further purify the wastewater. The treated wastewater enters the membrane bioreactor frame 1301.

[0239] In the membrane bioreactor frame 1301, the membrane 1302 filters the wastewater and intercepts the remaining suspended matter, colloids and microbial pollutants in the wastewater. The aeration effect of the aeration pipe 1303 and the fan 1304 reduces membrane pollution and maintains the membrane flux and filtration performance. The treated wastewater is pumped to the monitoring frame 1401 by the suction pipe 1305 and the suction pump 1306.

[0240] The monitoring framework 1401 mixes the wastewater evenly through the fourth driver 1402 and the fourth agitator 1403, the fifth driver 1404 and the fifth agitator 1405, and uses water quality monitoring equipment to monitor and analyze various indicators of the wastewater in real time. If the water quality meets the standard, the wastewater is discharged to the local sewage network through the lifting pump 1406 and the outlet pipe 1407 to ensure that the final effluent water quality meets the emission standards, thereby achieving efficient purification and standard treatment of various complex wastewaters in the experimental park, and ensuring the environmental quality of the park and the rational use of water resources.

[0241] The present invention has been described in detail above by general description and specific embodiments, but it is obvious to those skilled in the art that some modifications or improvements can be made on the basis of the present invention.
