[0193] (S07) The second self-priming pump 901 pumps the anaerobically sedimented washing wastewater to the facultative reaction tank 903. The oil-containing sewage generated in the experimental park is treated by the oil separation assembly 1500 and then enters the facultative reaction tank 903 to mix with the washing wastewater. In the facultative environment, microorganisms are used to further treat the wastewater to remove organic matter and nitrogen and phosphorus pollutants. The oil separation assembly 1500 is cleaned every week to prevent oil accumulation from affecting the oil separation effect.

[0194] (S08) The third diaphragm pump 1001 transports the facultatively treated washing wastewater to the aerobic frame 1003.

[0229] Embodiment:

[0230] This embodiment takes a certain experimental park as an example, which includes a scientific research office area and a living supporting area, and is connected to the sewage pipe network of the place.

[0231] In this embodiment, the main sources of washing wastewater are the underwater acoustic detection research and test support laboratory, the micro-nano processing laboratory, the material public support laboratory, the fruit fly larva research laboratory, the biological computing experiment laboratory, and the domestic sewage generated by the daily life of scientific researchers, as well as the oil-containing wastewater generated by the canteen.

[0232] In this embodiment, 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 during the cleaning process of experimental instruments. The characteristics are complex composition and irregular discharge. The one-time discharge amount is small but the intermittence is strong. The water quality composition fluctuates greatly due to the influence of experimental projects and reagents. Due to the particularity of micro-nano processing technology, the washing wastewater of the micro-nano processing laboratory contains small particle suspensions, organic photoresist and some special metal ions. The wastewater discharge also presents the characteristics of intermittence and small flow, and the water quality is required to be high in purity, which is difficult to handle. The material public support laboratory involves the testing and processing of various materials, and the generated wastewater contains different types of metal ions, acid-base substances and high molecular polymers. The water quality changes diversely, and the pollutant concentration varies due to experimental materials and operation steps. The washing wastewater of the fruit fly larva research laboratory mainly contains biological metabolites, organic nutrients and a small amount of disinfectant residues, which has certain biological pollution. The discharge time and flow of the wastewater are related to the experimental period and are unstable. The wastewater generated by the biological computing experiment 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 biological active substances need to be properly treated to avoid potential harm to the environment. The sewage generated by the daily life of scientific researchers has similar water quality composition to ordinary domestic sewage, mainly containing organic matter, nitrogen and phosphorus compounds, suspended solids and microorganisms. However, the sewage quantity is relatively stable, has certain biodegradability, and can be preliminarily treated by conventional biological treatment method. The wastewater generated by the canteen during the food processing process contains a large amount of oil, food residues and a certain amount of detergent. The oil content of the wastewater is high, and if it is directly discharged, it will cause blockage and pollution to the pipeline and subsequent wastewater treatment facilities, so it needs to be treated by oil separation first.

[0233] In this embodiment, the washing wastewater generated by various laboratories is first collected and transported to the flow limiting frame 302 of the adjusting assembly through the sewage pipe 301. According to the data monitored by the flow meter and the pH value information fed back by the pH sensor, the multiple rotatable flow limiting plates in the flow limiting frame 302 separate and temporarily store the washing wastewater with different compositions in different time periods, and accurately add acid-base adjusting liquid to adjust the pH value of the wastewater. At the same time, the inflow speed and temporary storage amount of the wastewater are strictly controlled until the preset water amount and acid-base balance are reached, and then the control valve 303 is opened to make the washing wastewater stably enter the coagulation and sedimentation frame 401 of the coagulation and sedimentation assembly.

[0234] In the coagulation and sedimentation frame 401, the calcium chloride solution, the polyaluminum chloride solution and the polyacrylamide solution are added, the first agitator 403 and the second agitator 405 in the flow guide cylinder 404 are driven by the first driver 402 to mix the wastewater and the reagents sufficiently, so as to promote the coagulation reaction of the suspended solids and colloids and accelerate the sedimentation process. After the sedimentation, the sludge is deposited at the bottom of the frame and is discharged through the first sludge discharge pipe 406 to the sludge concentration tank 901, and the supernatant is discharged through the water weir 407 to the ozone reaction column 501 of the ozone oxidation assembly.

[0235] In the ozone oxidation assembly, the ozone generated by the ozone generator 502 is fully contacted with the washing wastewater in the ozone reaction column 501 to oxidize the organic matter, bacteria and viruses in the wastewater and enhance the biodegradability of the wastewater. The oxygen generator and the ozone concentration analyzer integrated in the ozone generator 502 ensure that the ozone generation amount is appropriate and the concentration is stable, and the excess ozone is discharged after being treated by the ozone destroyer 503, and the oxidized wastewater enters the intermediate tank 601 through the flow guide pipe.

[0236] The domestic sewage generated in the experimental park first enters the composting assembly, is subjected to multi-stage anaerobic fermentation and sedimentation treatment in the first composting barrel 701, the second composting barrel 702 and the third composting barrel 703, decomposes the organic matter in the sewage, kills bacteria and parasite eggs, and then the treated domestic sewage enters the intermediate tank 601 through the sewer pipe 704 to be mixed with the washing wastewater. Subsequently, the mixed wastewater is transported to the three-phase separation barrel 802 by the second diaphragm pump 801, and the wastewater is circulated by the circulating pump 803 to promote the decomposition of macromolecular organic matter into small molecular organic matter, so as to realize the three-phase separation of water, gas and sludge.

[0237] 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, is uniformly distributed through the central pipe 806 and the reflecting plate 807, and then enters the anaerobic sedimentation frame 808 for sedimentation. The sludge is deposited at the bottom and is discharged through the second sludge discharge pipe 809 to the sludge concentration tank 901, and the supernatant is pumped to the facultative reaction tank 1001 by the second self-priming pump 810.

[0238] The oil-containing wastewater generated in the dining hall 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 oil-containing wastewater. The oil stains are intercepted and collected in the oil storage box 1105, and the wastewater subjected to the preliminary oil separation treatment is mixed with other wastewater in the facultative reaction tank 1001 through the drainage pipe 1106. In the facultative environment, the wastewater is further treated by using microorganisms to remove the organic matter and nitrogen and phosphorus pollutants therein.

[0239] The wastewater treated by the facultative treatment is delivered to the aerobic frame 1202 by the third diaphragm pump 1201, the aeration pump 1203 fills air into the wastewater in the aerobic frame 1202 through the aeration disc 1204, provides sufficient oxygen for the aerobic microorganisms, makes the aerobic microorganisms fully decompose the organic matters in the wastewater, further purifies the wastewater, and the treated wastewater enters the membrane biological reaction frame 1301.

[0240] In the membrane biological reaction frame 1301, the membrane 1302 filters the wastewater, retains the residual suspended solids, colloids and microbial pollutants in the wastewater, the aeration of the aeration pipe 1303 and the fan 1304 reduces the membrane pollution, maintains the membrane flux and the filtration performance, and the treated wastewater is pumped to the monitoring frame 1401 by the suction pipe 1305 and the suction pump 1306.

[0241] The monitoring frame 1401 mixes the wastewater uniformly by the fourth driver 1402 and the fourth stirrer 1403, the fifth driver 1404 and the fifth stirrer 1405, uses the water quality monitoring equipment to monitor and analyze the indexes of the wastewater in real time, discharges the wastewater to the sewage pipe network of the place by the lifting pump 1406 and the water outlet pipe 1407 if the water quality meets the standard, ensures that the final effluent quality meets the discharge standard, realizes efficient purification and standard treatment of various complex wastewaters in the experimental park, and guarantees the environmental quality of the park and the reasonable utilization of water resources.
