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 from the unit area directly enters the flow mixing pipe and then is mixed with the rainwater in the presence of rainfall, the mixed water of the rainwater and the sewage is easily polluted seriously when being directly discharged into the natural water body, and if being 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 unit area can be regulated and stored by the sewage regulation and storage device provided by the embodiment of the specification when rainfall occurs, and the sewage regulation and storage can be stopped when no rainfall occurs, namely, the sewage output by the unit area is directly input to the flow merging pipe 30;
that is, when the rainfall needs to regulate and store the sewage, the first switch 121 is turned off, and certainly, the second switch can be turned off synchronously, at this time, the overflow water outlet area 201 is connected with the sewage outlet of the unit area, so that the sewage in the unit area firstly flows into the overflow water outlet area 201, the water level in the overflow water outlet area 201 continuously rises along with the continuous inflow of the sewage until the water level exceeds the maximum capacity liquid level of the overflow water outlet area 201, and the overflow water inlet area 202 receives and stores the overflow sewage, thereby achieving the purpose of storing the sewage in the rainy day; when sewage does not need to be regulated and stored in fine days, the first switch and the second switch are opened at the moment, only the sewage passes through the first straight pipe 203 under the action of self gravity, the overflow water inlet area 202 flows into the cut-off part 10 through the first straight pipe 203 and finally flows out through the flow merging pipe 30, the technical defects that the sewage input by the sewage containing facility 20 in the prior art directly enters the flow merging pipe to be output in rainy days, the natural water body is extremely easy to cause serious pollution, the sewage treatment facility has overlarge treatment pressure, the resource waste and the like are effectively overcome, the technical effect of regulating and storing the sewage when the sewage is not required to be discharged is achieved, and the sewage treatment device 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 size of rainfall for regulation, for example, when the rainfall is relatively large, if the sewage output from the unit area directly enters the flow mixing pipe and then is mixed with the rainwater, the mixed water of the rainwater and the sewage is easily polluted seriously when being directly discharged into the natural water body, and if being directly discharged 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, the sewage output from the unit area can be regulated by the sewage regulation and storage device provided in the embodiment of the present specification when the rainfall is relatively large, and the sewage regulation and storage can be stopped when the rainfall is relatively small, that is, the sewage output from the unit area is directly input to the flow merging pipe 30 at this time.
That is, when the sewage needs to be regulated, the first switch 121 is turned off, and certainly, the second switch can be turned off synchronously, at this time, the overflow water outlet area 201 is connected with the sewage outlet of the unit area, so that the sewage in the unit area firstly flows into the overflow water outlet area 201, the water level in the overflow water outlet area 201 continuously rises along with the continuous inflow of the sewage until the water level exceeds the maximum capacity liquid level of the overflow water outlet area 201, and the overflow water inlet area 202 receives and stores the overflow sewage, thereby achieving the purpose of storing the sewage when the rainfall is relatively large; and when rainfall ratio need not carry out the regulation to sewage, open first switch and second switch this moment, only need sewage through first straight-through pipe 203 under self action of gravity, by the regional 202 warp of overflow intaking first straight-through pipe 203 flows in the damming portion 10 to finally flow out by the confluence pipe 30, effectually avoided among the prior art to the sewage of acceping facility 20 input by sewage directly get into the structural design place that the confluence pipe exported and very easily cause natural water serious pollution when the rainy day, perhaps sewage treatment facility treatment pressure is too big, technical defect such as wasting of resources, can reach the technological effect of carrying out the regulation to sewage when not needing sewage discharge, have simple structure, convenient operation and extensive applicability's characteristics.
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.
As another application environment of the embodiment of the present specification, for the above-mentioned sewage, a liquid level interval threshold is preset according to a liquid level height in an overflow water inlet area, and the liquid level height in the overflow water inlet area is monitored in real time, so that when the liquid level height is lower than a minimum value of the interval threshold, it is determined that the sewage needs to be regulated, that is, the sewage output by the unit area flows into the overflow water inlet area to be stored. When the liquid level is higher than the maximum value of the threshold value of the interval, the sewage storage can be stopped, namely, the sewage output by the unit area is directly input into the flow merging pipe 30 at the moment.
That is, when the sewage needs to be regulated, the first switch 121 is turned off, and of course, the second switch can be turned off synchronously, at this time, the overflow outlet area 201 is connected with the sewage outlet of the unit area, so that the sewage in the unit area firstly flows into the overflow outlet area 201, as the sewage continues to flow in, the water level in the overflow outlet area 201 continuously rises until the water level exceeds the maximum capacity liquid level of the overflow outlet area 201, overflow occurs, and the overflow inlet area 202 receives and stores the overflow sewage, so that when the liquid level is lower than the minimum value of the interval threshold value, the storage space of the overflow inlet area is large at this time, and the sewage is stored in order to reduce the delivery pressure of the flow merging pipe, the treatment pressure of the sewage treatment facility and the like; the technical defects of high conveying pressure of the confluence pipe, excessive treatment pressure of a sewage treatment facility, resource waste and the like are effectively overcome.
As another application environment of the embodiment of the present specification, a regulation node may be set to regulate according to whether a sewage treatment plant has spare capacity, for example, if the sewage from the unit area directly enters the confluence pipe when the sewage treatment plant has no spare capacity, the treated water is directly conveyed to a sewage treatment plant in the non-rainfall period or is mixed with rainwater and then conveyed to the sewage treatment plant in the rainfall period, so that the treated water entering the sewage treatment plant is excessive to reach the upper treatment limit of the sewage treatment plant, overflow is easy to occur, therefore, the sewage output by the sewage housing facility 20 can be regulated by the sewage regulating and storing device provided in the embodiment of the present specification, when the sewage treatment plant has a surplus capacity, the sewage storage can be stopped, that is, the sewage output from the sewage storage facility 20 is directly input into the confluence pipe 30.
