Example one
Specifically, referring to fig. 3, in the sewage storage and regulation method based on vacuum intake water, the method may include the following steps:
receiving an identification instruction whether the buffer part needs to store water or not;
if yes, controlling the first switch to be closed;
judging whether the liquid level height of the sewage in the intercepting part reaches a preset first liquid level height threshold value or not;
if so, triggering a control instruction for vacuumizing the buffer part so as to vacuumize the buffer part through the vacuum pump and form a pressure difference between the buffer part and the cut-off part;
the sewage in the intercepting part flows into the buffer part for storage under the action of the air pressure difference;
receiving an identification instruction whether the buffer part needs to discharge water or not;
if yes, controlling the first switch to be turned on;
judging whether the liquid level height of the sewage in the intercepting part reaches a preset second liquid level height threshold value or not;
if so, triggering a control instruction for communicating the buffer part with the external atmospheric pressure so as to communicate the buffer part with the external atmospheric pressure;
the sewage in the buffer portion flows into the cut-off portion under the action of gravity.
Specifically, the sewage storage method based on vacuum intake provided in the first embodiment may be specifically applied to the operation of starting to perform vacuum pumping when water storage is required, and of course, for the present invention, there is also an operation of performing vacuum pumping when water storage is not required, which may be understood as a "slow" vacuum pumping process in the process, which is not described in the first embodiment, and the process will be described in detail in the third embodiment.
For the first embodiment, the power supply externally connected to the vacuum pump 130 may be a power supply device or a power supply apparatus directly used for supplying power (such as industrial power supply or domestic power supply) as shown in fig. 2, or may be a solar power supply apparatus 140 as shown in fig. 1, at this time, the power supply device or the power supply apparatus is electrically connected to the vacuum pump, when water storage is needed, the first switch is controlled to be turned off, the sewage in the cut-off portion is stopped from flowing into the confluence pipe, and after the first switch is controlled to be turned off, whether the liquid level height of the sewage in the cut-off portion reaches a preset first liquid level height threshold value is synchronously determined; the first liquid level height threshold value is a liquid level value capable of pumping sewage in the cut-off part under the vacuum state of the buffer part, if so, a control instruction for vacuumizing the buffer part is triggered, so that the buffer part is vacuumized by a vacuum pump, and an air pressure difference is formed between the buffer part and the cut-off part; then the sewage in the cut-off part automatically flows into the buffer part for storage under the action of the air pressure difference, so that only rainwater exists in the confluence pipe. When an identification instruction that the buffer part needs to discharge water is received, whether the liquid level height of the sewage in the intercepting part reaches a preset second liquid level height threshold value is judged; here, the second liquid level height threshold is a liquid level value at which the sewage flows toward the cut-off portion by its own weight in a state where the buffer portion is restored to the atmospheric pressure, and is smaller than the first liquid level height threshold. If so, triggering a control instruction for communicating the buffer part with the external atmospheric pressure so as to communicate the buffer part with the external atmospheric pressure; thus, after the air pressure difference disappears, the sewage in the buffer part flows into the interception part under the action of gravity and is discharged by the confluence pipe. The sewage treatment device effectively avoids the technical defects that the sewage input by the sewage containing facility directly enters the confluence pipe to be output in the discharge mode in the technology is easy to cause serious pollution to natural water in rainy days, or the sewage treatment facility has overlarge treatment pressure, resource waste and the like, can achieve the technical effect of regulating and storing the sewage when the sewage discharge is not needed, and has the characteristics of convenient operation and wide applicability.
In the process of vacuumizing the buffer part by the vacuum pump, one end of the water pumping pipe in the cut-off part is submerged in the sewage in the cut-off part, namely, the height of one end of the water pumping pipe in the cut-off part is always below the liquid level of the sewage in the cut-off part.
It should be noted that, when a control command for communicating the buffer portion with the external atmosphere is triggered to communicate the buffer portion with the external atmosphere, as a control manner, a first valve 406 and a second valve 407 are disposed at the top of the buffer portion, where the first valve connects the buffer portion with the vacuum pump, and the second valve connects the buffer portion with the external atmosphere, when water storage is required and vacuum pumping is performed by the vacuum pump, the second valve is closed, the first valve is opened, and when water drainage is required, the second valve is opened, and the first valve is closed. As another control method, the buffer part may be respectively communicated with the vacuum pump and the external atmosphere through a two-position three-way electromagnetic valve. The embodiment of the present invention is not limited, and the technical effects of the control manner of communicating the buffer portion with the external atmospheric pressure when the water needs to be stored and the water needs to be discharged by the vacuum pump are all applicable to the present invention and are within the protection scope of the present invention.
In accordance with a first embodiment of the present invention, the instruction for receiving the identification of whether the buffer portion needs to store water is one or more of the following instructions: identification instructions a1 for characterizing that the current period is a rainfall period; and/or, the identification instruction B1 for characterizing that the current period is rainfall intensity greater than the base intensity threshold; and/or, the identification instruction C1 for characterizing that the current time period is that the capacity data of the sewage treatment plant is greater than its maximum capacity threshold; and/or, the identification instruction D1 is used for indicating that the capacity data of the buffer part in the current period is less than the maximum capacity threshold value; and/or, identification instructions E1 for characterizing that the current time period is a rain concentration less than a pollutant concentration threshold. The identification instruction for receiving whether the buffer part needs to discharge water is one or more of the following instructions: identification instructions A2 for characterizing a current period as a period of non-rainfall; and/or, the identification instructions B2 for characterizing that the current time period is a rainfall intensity less than the base intensity threshold; and/or, the identification instruction C2 for characterizing that the current time period is that the capacity data of the sewage treatment plant is less than its maximum capacity threshold; and/or, the identification instruction D2 is used for indicating that the capacity data of the buffer part is larger than the maximum capacity threshold value of the buffer part in the current period; and/or, identification instructions E2 for characterizing that the current time period is a rain concentration greater than a pollutant concentration threshold.
Specifically, as an application environment of the embodiment of the present specification, for the above-mentioned sewage, a regulation node may be set according to the situations of rainfall and no rainfall for regulation, for example, if the sewage output by the sewage storage facility directly enters the flow mixing pipe and then is mixed with the rainwater, when the rainfall exists, the mixed water of the rainwater and the sewage is directly discharged into the natural water body, the received water body is easily seriously polluted, and if the mixed water is directly discharged into the sewage treatment facility for treatment, a large amount of clean rainwater in rainy days enters the sewage treatment facility for unnecessary treatment, which results in resource waste. Therefore, the sewage output by the sewage storage facility 20 can be stored by the sewage storage method provided by the embodiment of the present specification when there is rainfall, and the sewage storage can be stopped when there is no rainfall, that is, the sewage output by the sewage storage facility 20 is directly input to the confluence pipe;
that is, when the rain needs to regulate and store the sewage, only the first switch is controlled to be closed, the first valve is controlled to be opened, the second valve is controlled to be closed, the buffer part is vacuumized by the vacuum pump, the air pressure difference between the cut-off part and the buffer part is formed, the sewage in the cut-off part is pressed into the buffer part to be stored under the action of the air pressure difference, only the rainwater exists in the flow combining pipe, when the sewage is required to be output in fine days, only the first switch is controlled to be opened, the first valve is closed, the second valve is opened, the air pressure in the buffer part is recovered to the atmospheric pressure, the sewage stored in the buffer part flows into the cut-off part under the action of the self gravity and is discharged by the flow combining pipe, and the serious pollution of the natural water body caused by the structural design that the sewage input by the sewage containing facility 20 directly enters the flow combining pipe to be output in the prior art is effectively avoided, or the technical defects of overlarge treatment pressure, resource waste and the like of the sewage treatment facility can achieve the technical effect of regulating and storing the sewage when the sewage is not required to be discharged, and the sewage treatment facility has the characteristics of simple structure, convenience in operation and wide applicability.
As another application environment of the embodiment of the present specification, for the above-mentioned sewage, a regulation node may be set according to the magnitude of rainfall for regulation, for example, if the rainfall is relatively large, if the sewage output by the sewage storage facility directly enters the flow mixing pipe and then is mixed with the rainwater, the mixed water of the rainwater and the sewage is discharged directly into the natural water body, which is very likely to cause serious pollution to the received water body, and if the sewage is discharged directly into the sewage treatment facility for treatment, a large amount of relatively clean rainwater in rainy days enters the sewage treatment facility for unnecessary treatment, which results in resource waste. Therefore, at this time, when the rainfall is relatively large, the sewage output by the sewage containing facility can be regulated and stored by the sewage regulating and storing method provided by the embodiment of the specification, and when the rainfall is relatively small, the sewage regulation and storage can be stopped, that is, the sewage output by the sewage containing facility is directly input to the confluence pipe at this time.
That is, when the rainfall is large and the sewage needs to be regulated and stored, the first switch needs to be controlled to be closed, the first valve is controlled to be opened, the second valve is controlled to be closed, the buffer part is vacuumized by the vacuum pump, so that the air pressure difference between the cut-off part and the buffer part is formed, the sewage in the cut-off part is pressed into the buffer part to be stored under the action of the air pressure difference, only rainwater exists in the flow combining pipe, when the rainfall is small and the sewage is required to be output, only the first switch needs to be controlled to be opened, the first valve is closed, the second valve is opened, the air pressure in the buffer part is recovered to the atmospheric pressure, the sewage stored in the buffer part flows into the cut-off part under the action of self gravity and is discharged by the flow combining pipe, and natural serious pollution caused by the structural design that the sewage input by the sewage containing facility 20 directly enters the flow combining pipe to be output in the prior art is effectively avoided, or the technical defects of overlarge treatment pressure, resource waste and the like of the sewage treatment facility can achieve the technical effect of regulating and storing the sewage when the sewage is not required to be discharged, and the sewage treatment facility has the characteristics of simple structure, convenience in operation and wide applicability.
Those skilled in the art can understand that, regarding the magnitude and the size of the rainfall, the present invention is not limited, and the rainfall parameter threshold may be set according to the actual operation requirement for defining.

if yes, controlling the first switch to be closed;

if so, triggering a control instruction for communicating the buffer part with the external atmospheric pressure so as to communicate the buffer part with the external atmospheric pressure;
the sewage in the buffer portion flows into the cut-off portion under the action of gravity.
Since the second embodiment and the first embodiment are the same in the same inventive concept, and the second embodiment constitutes a hardware control portion in the first embodiment, and the control method thereof is completely the same as that in the first embodiment, the control method of the second embodiment is not repeated herein, and the detailed description is not referred to the first embodiment.
EXAMPLE III
Specifically, referring to fig. 4, in the sewage storage and regulation method based on vacuum intake water, the method may include the following steps:
acquiring vacuum degree data information in the buffer part;
judging whether the buffer part needs to be vacuumized or not according to the vacuum degree data information;
if so, triggering a control instruction for vacuumizing the buffer part so as to vacuumize the buffer part through the vacuum pump and form a pressure difference between the buffer part and the cut-off part;
receiving an identification instruction whether the buffer part needs to store water or not;
if yes, controlling the first switch to be closed;
judging whether the liquid level height of the sewage in the intercepting part reaches a preset first liquid level height threshold value or not;
if so, the sewage in the intercepting part flows into the buffer part under the action of the air pressure difference to be stored.
Specifically, for the first embodiment, the power source externally connected to the vacuum pump 130 may be a power supply device or a power supply device directly used for supplying power (such as industrial power supply or domestic power supply) as shown in fig. 2, or may be a solar power supply device as shown in fig. 1, where the power supply device or the power supply device is electrically connected to the vacuum pump. The sewage storage method based on vacuum intake provided by the third embodiment may be specifically applied to performing a vacuum pumping action when water storage is not required, and it corresponds to the first embodiment, and may be understood that the process is a "slow" vacuum pumping process, because in a non-rainfall period (e.g., in a sunny day), the sewage does not need to be stored, and when the power supply externally connected to the vacuum pump 130 is a solar power supply device, solar energy may be fully utilized to pre-pump the buffer portion, so that when the sewage needs to be stored, the second switch 122 additionally arranged between the buffer portion and the cut-off portion is directly opened. The electric energy is greatly saved, and certainly, the invention is also applicable to the case that the sewage in the cut-off part slowly enters the buffer part for pre-storage when the buffer part is slowly vacuumized by removing the second switch 122, and the details are not repeated herein.
Specifically, the vacuum degree data information in the buffer part can be obtained firstly, and then whether the buffer part needs to be vacuumized is judged according to the vacuum degree data information; if the pressure difference exists (the situation may be sunny days), triggering a control instruction for vacuumizing the buffer part so as to realize (slowly) vacuumizing the buffer part in advance by electrically connecting the solar equipment or the electric power equipment with the vacuum pump and form a pressure difference between the buffer part and the cut-off part in advance; at this time, if the sewage is not required to enter the buffer part, the second switch 122 can be closed, and if the sewage is required to enter the buffer part, before the second switch is controlled to be opened, whether the liquid level height of the sewage in the cut-off part reaches a preset first liquid level height threshold value can be judged; the first liquid level height threshold value is a liquid level value capable of pumping sewage in the cut-off part under the vacuum state of the buffer part, if yes, the second switch is controlled to be switched on, sewage storage is achieved, and then when an identification instruction that the buffer part needs to discharge water is received, whether the liquid level height of the sewage in the cut-off part reaches a preset second liquid level height threshold value or not is judged; here, the second liquid level height threshold is a liquid level value at which the sewage flows toward the cut-off portion by its own weight in a state where the buffer portion is restored to the atmospheric pressure, and is smaller than the first liquid level height threshold. If so, triggering a control instruction for communicating the buffer part with the external atmospheric pressure to communicate the buffer part with the external atmospheric pressure; thus, after the air pressure difference disappears, the sewage in the buffer part flows into the interception part under the action of gravity and is discharged by the confluence pipe. The sewage treatment device effectively avoids the technical defects that the sewage input by the sewage containing facility directly enters the confluence pipe to be output in the discharge mode in the technology is easy to cause serious pollution to natural water in rainy days, or the sewage treatment facility has overlarge treatment pressure, resource waste and the like, can achieve the technical effect of regulating and storing the sewage when the sewage discharge is not needed, and has the characteristics of convenient operation and wide applicability.
In the process of vacuumizing the buffer part by the vacuum pump, one end of the water pumping pipe in the cut-off part is submerged in the sewage in the cut-off part, namely, the height of one end of the water pumping pipe in the cut-off part is always below the liquid level of the sewage in the cut-off part.
It should be noted that, when a control command for communicating the buffer portion with the external atmosphere is triggered to communicate the buffer portion with the external atmosphere, as a control manner, a first valve and a second valve may be disposed at a top of the buffer portion, where the first valve connects the buffer portion with a vacuum pump, the second valve connects the buffer portion with the external atmosphere, when water needs to be stored and vacuum pumping is performed through the vacuum pump, the second valve is closed, the first valve is opened, and when water needs to be drained, the second valve is opened, and the first valve is closed. As another control method, the buffer part may be respectively communicated with the vacuum pump and the external atmosphere through a two-position three-way electromagnetic valve. The embodiment of the present invention is not limited, and the technical effects of the control manner of communicating the buffer portion with the external atmospheric pressure when the water needs to be stored and the water needs to be discharged by the vacuum pump are all applicable to the present invention and are within the protection scope of the present invention.
