Description

Technical Field

[0001] The present invention relates to the field of wastewater disposal in ecological environment protection. Specifically, it relates to an automatic disposal system and method for excessive discharge of external wastewater. Background Art

[0002] At present, most industrial enterprises use automatic pollution source monitoring facilities for wastewater supervision, realizing real-time monitoring of external wastewater. However, this technology mainly focuses on automatic water quality detection, only being able to monitor the situation of water quality exceeding the standard, with relatively single functions, and unable to automatically and effectively dispose of the abnormal situation of excessive discharge of external wastewater.

[0003] Although some key enterprises arrange special personnel to closely monitor the automatic pollution source monitoring data, there are often situations where the staff are distracted. Especially for night shift personnel, they cannot timely detect the situation of data exceeding the standard, or even if they do, they need to rely on manual operation to close the external wastewater valve and divert the external wastewater into the emergency pond. After a series of operations, it not only consumes a lot of time but also cannot immediately stop the discharge of excessive wastewater, having a greater impact on the external environment.

[0004] Therefore, the technical personnel in this field are committed to developing an automatic disposal system and method for excessive discharge of external wastewater based on automatic pollution source monitoring facilities, which can timely detect and automatically and efficiently dispose of the situation of excessive wastewater discharge. Summary of the Invention

[0005] An automatic disposal system and method for excessive discharge of external wastewater provided by the present invention are realized by adopting the following technical solutions:

[0006] An automatic disposal system for excessive discharge of external wastewater includes a wastewater discharge pipe 1, a wastewater transfer tank 2, a connecting pipe 3 leading to a Parshall flume, a solenoid valve 4, a Parshall flume 5, an automatic pollution source monitoring facility 6, an audible and visual alarm 7, a liquid level controller 8, a water pump 9, a return pipe 10, and a sampling pipe 11.

[0007] Preferably, the wastewater discharge pipe 1 is installed 20 cm below the top of the wastewater transfer tank 2, and the connecting pipe 3 leading to the Parshall flume is installed 50 cm below the top of the wastewater transfer tank 2 and leads to the Parshall flume 5; the solenoid valve is installed on the connecting pipe 3 leading to the Parshall flume. The automatic pollution source monitoring facility 6 regularly samples and detects the water in the wastewater transfer tank 2 through the sampling pipe 11, and the sampling pipe 11 is installed 20 cm above the bottom of the wastewater transfer tank 2; the water pump 9 is installed 20 cm above the bottom of the wastewater transfer tank 2 and is connected to the return pipe 10, and the return pipe 10 leads to the emergency pond; the upper liquid level set by the liquid level controller 8 is flush with the wastewater discharge pipe 1, and the lower liquid level is flush with the connecting pipe 3 leading to the Parshall flume.

[0008] Preferably, the pollution source automatic monitoring facility 6 is connected to the solenoid valve 4 and the sound and light alarm 7 by a signal control line; the liquid level controller 8 is connected to the water pump 9 by a signal control line, and the solenoid valve 4 is in a normally open state.

[0009] Preferably, the drainage capacity design of the automatic disposal system for discharged wastewater exceeding the standard needs to satisfy the requirement that the drainage capacity of the connecting pipe 3 leading to the Pasteur tank is greater than the drainage capacity of the water pump 9, and the drainage capacity of the water pump 9 is greater than the drainage capacity of the wastewater discharge pipe 1, to ensure that the wastewater exceeding the standard does not overflow.

[0010] The present invention also provides a method for using the system for automatically disposing of excessive wastewater discharged from the environment, the method comprising:

[0011] (1) When discharging wastewater normally, the solenoid valve 4 on the connecting pipe to the pasteurization tank is in a normally open state, and the sewage treatment station discharges the wastewater that meets the treatment standards through the wastewater discharge pipe 1 to the wastewater transfer tank 2, and then discharges it to the pasteurization tank 5 through the connecting pipe 3 to the pasteurization tank, and then discharges it outside the plant;

[0012] (2) The pollution source automatic monitoring facility 6 takes water samples from the wastewater transfer tank 2 through the sampling tube 11 for testing. When it is detected that the water quality standard exceeds the enterprise's allowable discharge concentration, the pollution source automatic monitoring facility 6 sends a signal to the solenoid valve 4 to automatically close the solenoid valve and stop discharging the excessive wastewater. At the same time, it sends a signal to the sound and light alarm 7 to activate the alarm and prompt the staff to come for processing;

[0013] (3) After closing the solenoid valve 4, the liquid level in the wastewater transfer tank 2 rises. When the liquid level rises to the same level as the wastewater discharge pipe 1, the liquid level controller 8 sends a signal to the water pump 9, automatically starting the water pump 9 to pump the excess wastewater back to the emergency tank through the return pipe 10 to prevent the excess wastewater from overflowing;

[0014] (4) The staff of the sewage treatment station manually turns off the sound and light alarm 7 and immediately takes measures to adjust the sewage treatment process. During this period, the pollution source automatic monitoring facility 6 continues to take water samples from the wastewater transfer tank 2 for testing. After detecting that the discharged wastewater meets the standards, the pollution source automatic monitoring facility 6 sends a signal to the solenoid valve 4, which automatically opens the solenoid valve and discharges the wastewater that meets the standards normally.

[0015] (5) When the liquid level drops to the same level as the connecting pipe 3 leading to the Pasteur tank, the liquid level controller 8 sends a signal to the water pump 9 to automatically shut down the water pump 9.

[0016] At this point, the automatic wastewater excess disposal system has returned to its initial state and continues to function.

[0017] In summary, the beneficial effects of this application are:

[0018] (1) Based on the real-time analysis data of the pollution source automatic monitoring facility 6, by controlling the solenoid valve 4 and the sound and light alarm 7, the discharge of wastewater exceeding the standard can be cut off immediately, and at the same time, the sewage treatment station staff can be reminded to take timely measures to adjust the sewage treatment process;

[0019] (2) With the help of the liquid level controller 8 and the water pump 9, the wastewater exceeding the standard is automatically pumped back to the emergency pool to prevent the wastewater exceeding the standard from overflowing. After it is detected that the discharged wastewater meets the standard, the solenoid valve is opened to discharge the wastewater meeting the standard normally, thus realizing the automatic disposal of the wastewater exceeding the standard.

[0023] The specific implementation of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. The implementation takes a wastewater transfer tank with a depth of 1.5 meters and a volume of 10 cubic meters as an example. The depth and volume of the wastewater transfer tank can be adjusted according to the actual water volume. It should be understood that the specific implementation described herein is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0024] An automatic disposal system for discharged wastewater exceeding the standard comprises a wastewater discharge pipe 1, a wastewater transfer tank 2, a connecting pipe leading to a pasteurization tank 3, a solenoid valve 4, a pasteurization tank 5, an automatic monitoring facility for pollution sources 6, an audible and visual alarm 7, a liquid level controller 8, a water pump 9, a return pipe 10, and a sampling tube 11.

[0025] When the wastewater is discharged normally, the solenoid valve 4 on the connecting pipe leading to the pasteurization tank is in the normally open state, and the sewage treatment station discharges the treated wastewater that meets the standards to the wastewater transfer tank 2 through the wastewater discharge pipe 1. When the liquid level reaches 50 cm below the top of the wastewater transfer tank 2, it is discharged to the pasteurization tank 5 through the connecting pipe 3 leading to the pasteurization tank, and then discharged out of the factory.

[0026] During the drainage period, the pollution source automatic monitoring facility 6 regularly takes water samples from the wastewater transfer tank 2 for testing. When it is detected that the water quality standard in the water transfer tank 2 exceeds the enterprise's allowable discharge concentration, the pollution source automatic monitoring facility 6 sends a signal to the solenoid valve 4, automatically closes the solenoid valve, and stops discharging the excessive wastewater; at the same time, it sends a signal to the sound and light alarm 7 to activate the alarm, prompting the staff to come for processing.

[0027] After closing the solenoid valve 4, the liquid level in the wastewater transfer tank 2 will gradually rise. When the liquid level rises to the same level as the wastewater discharge pipe 1, the liquid level controller 8 will send a signal to the water pump 9 to automatically start the water pump 9 to pump the excess wastewater back to the emergency tank through the return pipe 10. Because the drainage capacity of the water pump 9 is greater than the drainage capacity of the wastewater discharge pipe 1, the liquid level in the wastewater transfer tank 2 will gradually decrease, ensuring that the excess wastewater does not overflow.

[0028] After the staff of the sewage treatment station arrived at the scene, they manually turned off the sound and light alarm 7 and immediately took measures to adjust the sewage treatment process. During this period, the pollution source automatic monitoring facility 6 continued to take water samples from the wastewater transfer tank 2 for testing. After detecting that the discharged wastewater meets the standards, the pollution source automatic monitoring facility 6 sent a signal to the solenoid valve 4, automatically opened the solenoid valve, and discharged the wastewater that meets the standards normally.

[0029] Because the drainage capacity of the connecting pipe 3 leading to the Pasteur tank is greater than the drainage capacity of the water pump 9, and the drainage capacity of the water pump 9 is greater than the drainage capacity of the wastewater discharge pipe 1, the liquid level in the wastewater transfer tank 2 will gradually decrease. When the liquid level drops to the same level as the connecting pipe 3 leading to the Pasteur tank, the liquid level controller 8 sends a signal to the water pump 9 to automatically shut down the water pump 9.

[0030] At this point, the automatic wastewater excess disposal system has returned to its initial state and continues to function.
