Description

Technical Field

[0001] The present invention relates to the field of initial rainwater treatment in ecological environment protection, and in particular to an initial rainwater automatic treatment system and method. Background Art

[0002] Initial rainwater refers to rainwater at the initial stage of rainfall. During the production process of industrial enterprises, some raw and auxiliary materials will be spilled on the ground due to material transfer and vehicle transportation within the factory. The leakage of raw and auxiliary materials and sewage in daily management will also cause pollutants to remain on the ground. When it rains, rainwater falls to the ground and washes the factory ground to form runoff. Therefore, the initial rainwater contains many organic pollutants and heavy metals and other pollutants. If it is directly discharged into the water body through rainwater channels or rainwater pipes, it will cause a certain degree of pollution to the surrounding water environment. Therefore, it is necessary to collect and dispose of the initial rainwater.

[0003] At present, the common practice is to divert initial rainwater and later rainwater, collect initial rainwater, and after the collection pool is full, discharge the initial rainwater to a sewage treatment station for treatment, and then discharge it after meeting the standards.

[0004] Regarding the above-mentioned relevant treatment schemes, the inventor believes that the pollution level of initial rainwater is closely related to daily management. Not every collected initial rainwater will exceed the company's emission standards. Initial rainwater that does not exceed the standard can be discharged directly through the sewage outlet and does not need to be discharged into the sewage treatment plant. The most important thing is that the concentration of initial rainwater has not been tested, and the pollutant concentration is unclear, and the amount of chemicals added during sewage treatment cannot be effectively evaluated. Discharging all initial rainwater into the sewage treatment plant in general will not only increase the management cost of sewage treatment, but also there is a risk of exceeding the standard of wastewater discharged from the sewage treatment plant due to insufficient dosage. Summary of the invention

[0005] In order to more finely control the initial rainwater, ensure that the initial rainwater that meets the standards is directly discharged through the sewage discharge port, and the initial rainwater that does not meet the standards is discharged into the sewage treatment plant for steady and orderly treatment and discharged in compliance with the standards, the present invention provides an automatic treatment system and method for initial rainwater, which can realize the automatic treatment of initial rainwater and save more manpower and material resources.

[0006] The present invention provides an initial rainwater automatic treatment system and method which is implemented by the following technical solutions:

[0007] An initial rainwater automatic disposal system comprises an initial rainwater inlet pipe 1, an initial rainwater inlet pipe solenoid valve 2, an initial rainwater collection pool 3, a pollution source automatic monitoring facility 4, a liquid level control switch 5, a water pump 6, a three-way joint 7 for a water pump connecting pipe, a connecting pipe leading to a total sewage outlet 8, a connecting pipe leading to a sewage treatment station 9, a solenoid valve 10 on a connecting pipe leading to the total sewage outlet, and a solenoid valve 11 on a connecting pipe leading to a sewage treatment station.

[0008] Preferably, the initial rainwater inlet pipe 1 is installed 20 cm below the top of the initial rainwater collection pool 3, the water pump 6 is installed 20 cm from the bottom of the initial rainwater collection pool 3, the pollution source automatic monitoring facility 4 samples and detects the water in the initial rainwater collection pool 3 through the water intake pipe, and the solenoid valves are respectively installed on the initial rainwater inlet pipe 1, the connecting pipe 8 leading to the main sewage outlet, and the connecting pipe 9 leading to the sewage treatment station.

[0009] Preferably, the liquid level control switch 5 is connected to the initial rainwater inlet pipe solenoid valve 2, the water pump 6 and the pollution source automatic monitoring facility 4 by a signal control line. The initial rainwater inlet pipe solenoid valve 2 is in a normally open state, and the solenoid valve 10 on the connecting pipe leading to the main sewage outlet and the solenoid valve 11 on the connecting pipe leading to the sewage treatment station are both in a normally closed state.

[0010] Preferably, the pollution source automatic monitoring facility 4 is connected to the water pump 6, the solenoid valve 10 on the connecting pipe leading to the sewage main outlet, and the solenoid valve 11 on the connecting pipe leading to the sewage treatment station by using a signal control line.

[0011] Preferably, a water pump connecting pipe three-way joint 7 is arranged behind the connecting pipe of the water pump 6, which is respectively connected to the connecting pipe 8 leading to the sewage main outlet and the connecting pipe 9 leading to the sewage treatment station.

[0012] The present invention also provides a method for using the initial rainwater automatic disposal system, the method comprising:

[0013] (1) The initial rainwater enters the initial rainwater collection tank 3 through the initial rainwater inlet pipe 1. When the liquid level in the collection tank reaches the designed high liquid level (30 cm below the top), the liquid level control switch 5 sends a signal to the initial rainwater inlet pipe solenoid valve 2 to close the solenoid valve;

[0014] (2) At the same time, the liquid level control switch 5 sends a signal to the pollution source automatic monitoring facility 4 to take water from the initial rainwater collection pool 3 for detection and analysis. Two hours later, the initial rainwater quality detection value is displayed and compared with the enterprise sewage discharge standard value set by the pollution source automatic monitoring facility 4.

[0015] (3) If the water quality test value is less than the enterprise sewage discharge standard value, a signal is sent to the water pump 6 to start the water pump, and at the same time a signal is sent to the solenoid valve 10 on the connecting pipe leading to the sewage main outlet to open the solenoid valve, so that the water pump 6 discharges the initial rainwater in the initial rainwater collection tank 3 to the sewage main outlet;

[0016] (4) If the water quality test value is greater than the enterprise sewage discharge standard value, a signal is sent to the water pump 6 to start the water pump. At the same time, a signal is sent to the solenoid valve 11 on the connecting pipe leading to the sewage treatment station to open the solenoid valve. The water pump 6 discharges the initial rainwater in the initial rainwater collection tank 3 to the sewage treatment station.

[0017] (5) After the liquid level in the initial rainwater collection pool 3 reaches the designed low liquid level (30 cm above the bottom), the liquid level control switch 5 sends a signal to shut down the water pump 6, and the solenoid valve 10 or the solenoid valve 11 behind the water pump is closed, and the initial rainwater collection pool 3 is emptied.

[0018] In summary, the beneficial effects of this application are:

[0019] (1) The collected initial rainwater meets the enterprise's discharge standards. The initial rainwater that does not exceed the standards can be directly discharged through the sewage discharge port and does not need to be discharged into the sewage treatment plant, which can reduce the operating cost of sewage treatment;

[0020] (2) The collected initial rainwater exceeds the enterprise's discharge standard. The detection value of the initial rainwater quality by the pollution source automatic monitoring facilities can provide data support for the operation of the sewage treatment plant, reasonably put in sewage treatment chemicals, and ensure that the sewage meets the discharge standards;

[0021] (3) The present invention can realize automatic sampling, detection and analysis of the collected initial rainwater, and automatically dispose of the initial rainwater according to the detection value, thus saving more manpower and material resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The specific implementation of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. 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.

[0027] When it rains, the initial rainwater inlet pipe solenoid valve 2 is in the normally open state, and the initial rainwater flows into the initial rainwater collection pool 3 through the initial rainwater inlet pipe 1. The liquid level control switch 5 in the pool gradually rises. After reaching the designed high liquid level (30 cm below the top), the liquid level control switch 5 sends a signal to the initial rainwater inlet pipe solenoid valve 2 to close the solenoid valve.

[0028] At the same time, the liquid level control switch 5 sends a signal to the pollution source automatic monitoring facility 4 to take water from the initial rainwater collection pool 3 for detection and analysis. Two hours later, the initial rainwater quality detection value is displayed and compared with the enterprise sewage discharge standard value set by the pollution source automatic monitoring facility 4.

[0029] If the water quality test value is less than the enterprise sewage discharge standard value, a signal is sent to the water pump 6 to start the water pump, and at the same time a signal is sent to the solenoid valve 10 on the connecting pipe leading to the main sewage outlet to open the solenoid valve, and the water pump 6 discharges the initial rainwater in the initial rainwater collection tank 3 to the main sewage outlet.

[0030] If the water quality test value is greater than the enterprise sewage discharge standard value, a signal is sent to the water pump 6 to start the water pump, and at the same time a signal is sent to the solenoid valve 11 on the connecting pipe leading to the sewage treatment station to open the solenoid valve, and the water pump 6 discharges the initial rainwater in the initial rainwater collection pool 3 to the sewage treatment station.

[0031] After the liquid level in the initial rainwater collection pool 3 reaches the designed low liquid level (30 cm above the bottom), the liquid level control switch 5 sends a signal to shut down the water pump 6, and the solenoid valve 10 or the solenoid valve 11 behind the water pump is closed, and the initial rainwater collection pool 3 is emptied.

[0032] At this point, the initial rainwater automatic disposal system returns to its initial state and continues to be used.

[0033] It should be understood that the terms "below the top", "above the bottom", etc. indicate orientations based on the orientations shown in the accompanying drawings and are only for the convenience of describing the present invention, rather than indicating or implying a specific orientation. Two hours is the preferred time and therefore should not be construed as a limitation on the present invention.
