2. Description of the Related Art It is prescribed for users of sewerage to set the water quality value of wastewater to a certain standard value or less. However, malicious sewage that does not meet the standards (hereinafter referred to as malicious sewage) may flow into the sewer pipeline, which may damage the facility or reduce its function, or may interfere with the water treatment function to improve the quality of water discharged from the treatment plant. There was a fear of making it worse. Countermeasures when malicious sewage is generated include stopping the pump at the pump station, diluting it by storing it in the pipe, and discharging it, or diluting it with treated water at the terminal treatment plant.

On the other hand, for the purpose of controlling inundation during heavy rain and reducing the load of pollutants due to dust and pipe deposits during rainfall,

BEST MODE FOR CARRYING OUT THE INVENTION (Embodiment 1) FIG. 1 shows an operation apparatus for sewerage equipment in an embodiment of the present invention. The sewer pipe 1 and the sewage flowing in the sewer pipe 1 are stored as stored water in a storage facility 2 including an underground regulating pond and a rainwater storage pipe that can be temporarily stored. When the storage facility 2 is not installed side by side in the sewer pipeline 1, a facility that can temporarily store sewage may be provided. Sewage sewer line 1 to storage facility 2
The transfer to (1) is carried out via the intake means 3 composed of a movable weir or the like. The opening and closing of the take-in means 3 is controlled by a signal from a control means 4 including a microcomputer or the like.

A water quality measuring means 5 for measuring the quality of the sewage in the sewer pipe 1 is installed in the sewer pipe 1 upstream of the intake means 3 and sends the measured water quality information to the control means 4. Transmission of signals from the intake unit 3 and the water quality measuring unit 5 to the control unit 4 may be performed by using an optical fiber provided in the sewer. Further, it is desirable that the water quality measuring means 5 uses at least one of a pH meter, a conductivity meter, an oil film detector, a poison sensor, and a thermometer.

Next, the operation method of the present invention will be described.

According to the present invention, based on the water quality information from the water quality measuring means 5, the control means 4 controls or opens the intake means 3 when the water quality of the sewage has detected a preset water quality value or more. , Sewage is stored in the storage facility 2.

The water quality value above the standard value is set by referring to the drainage standard of a specific establishment, etc. In this embodiment, the water quality value above the standard value means that the sewerage system is caused by the flow of malicious sewage. It is said to cause damage such as damage or deterioration of function. When a pH meter is used, the range between the upper limit value and the lower limit value is called the reference value, and the water quality value outside the range is called the reference value or more. Storage facility 2 for malicious sewage that deviates from the upper limit
By storing the wastewater in the sewage system, it is possible to prevent damage such as damage to the sewerage system and deterioration of the function due to the flow of malicious sewage. In addition, rainwater storage facilities that have not been used except during rainfall can be effectively used. (Embodiment 2) FIG. 2 shows another embodiment of the present invention. There are a sewer pipe 11, a sewer pipe 12, a sewer pipe 13 and a sewer pipe 14 in the target basin, and the sewer flows into the pumping station 6 while gradually confluent. The pumping station 6 may be a terminal treatment plant. Flow rate measuring means 71, flow rate measuring means 72, flow rate measuring means 73, and flow rate measuring means 74 for measuring the amount of sewage water are installed in each sewer pipe.
Information on the flow rate of each sewer pipe is transmitted to the control means 4.

Further, the sewer pipe 11 is provided with a storage facility 2, an intake means 3, and a water quality measuring means 5 upstream of the intake means 3. The control means 4 controls the intake means 3 by the information of the water quality measuring means 5, the flow rate measuring means 71, the flow rate measuring means 72, the flow rate measuring means 73 and the flow rate measuring means 74.

The control flow of the embodiment of FIG. 2 will be described with reference to FIG. 3. Since the water quality measuring means 5 of FIG. 3 uses a pH meter, the range between the upper limit value and the lower limit value becomes the reference value. And
Outside this range, the water quality value is above the standard value.

The control means 4 receives the sewage water quality information A from the water quality measuring means 5. The control means 4 determines whether the water quality information A is in the range of the first lower limit value AL or more and the first upper limit value AH or less. If the water quality information A is within the above range, the process ends. still,
When the sewage is stored in the storage facility 2, the storage is stopped and then terminated.

Next, when the water quality information A is not less than the first lower limit value AL and not more than the first upper limit value AH, the control means 4 causes the water quality information A to be not less than the second lower limit value ALL and the second. It is determined whether the range is equal to or less than the upper limit value AHH. The second lower limit value ALL is smaller than the first lower limit value AL, and the second upper limit value AHH is larger than the first upper limit value AH.

When the water quality information A is in the range of the second lower limit value ALL or more and the second upper limit value AHH or less, the control means 4 controls the amount of water flowing into the pumping station 6 (a) and the amount of malicious sewage (b). And calculate the flow rate ratio Q (b / a)
And the flow rate reference value α are compared. The flow rate of the sewage flowing through the pump station 6 is obtained from the sum of the measured values of the flow rate measuring means 71, the flow rate measuring means 72, the flow rate measuring means 73, and the flow rate measuring means 74.

The flow rate of malicious sewage is measured by the flow rate measuring means 71.
It is obtained from the measured value of. The control means 4 ends when the flow rate ratio Q is smaller than the flow rate reference value α. In addition, when sewage is stored in the storage facility 2, the storage is terminated and then terminated. When the flow rate ratio Q is larger than the flow rate reference value α, the control means 4 controls the intake means 3 to store the sewage in the storage means 2.

Next, when the water quality information A is above the second lower limit value ALL and below the second upper limit value AHH, the control means 4 divides the amount of water flowing through the pumping station 6 and the amount of malicious sewage. The flow rate ratio Q is calculated, and the flow rate ratio Q is compared with the flow rate reference value β. The control means 4 ends when the flow rate ratio Q is smaller than the flow rate reference value β.

When sewage is stored in the storage facility 2, the storage is stopped and the process ends. When the flow rate ratio Q is larger than the flow rate reference value β, the control means 4 controls the intake means 3 to store the sewage in the storage means 2. The flow rate reference value α is smaller than the flow rate reference value β.

Also, the sewer line 12, the sewer line 13,
When a pump station is installed in any one or more of the sewer pipelines 14, the pump of the pump station can be controlled by the control means 4, and the water quality information A of the water quality measuring means 5 is first.
If the lower limit value AL or less and the first upper limit value AH or more,
Increase the pumped water output at the pumping station. Since the amount of water (a) flowing through the pumping station 6 increases, the bad sewage can be diluted.

The present invention has the following advantages. 1) It is possible to store malicious sewage that deviates from the upper limit value or the lower limit value in the storage facility 2 and prevent the distribution of the malicious sewage, and prevent damage such as damage to the sewer system or deterioration of the function due to the flow of the malicious sewage. 2) Rainwater storage facilities that have not been used except during rainfall can be effectively used. 3) Even for bad sewage, if it is diluted to a certain ratio or more by the confluence of the sewage before reaching the pumping station facility 6, the storage can be postponed and excessive storage can be prevented.

As described above, in FIG. 2, even if the water quality value of the sewer pipe 1 is above the standard value, the water quality values of the sewer line 12, the sewer line 13, and the sewer line 14 are below the standard value, and the pump When the water quality value of all sewer pipes is equal to or less than the reference value when flowing to the site facility 6, the sewage is flown to the pump station facility 6 without being stored in the storage facility 2. That is, the control means 4 controls the intake means 3 so as not to operate. In this case, if it is known in advance that the sewage of the sewer lines 12 to 14 is below the standard value of the water quality value, there is no problem, but if it is not known, the sewer pipe communicating with the pumping station facility 6 It goes without saying that the water quality measuring means 5A is installed in the road. (Embodiment 3) FIG. 4 shows an embodiment in which a function of returning the stored malicious sewage to the sewer pipe 1 is added. A return means 8 including a pump or the like for returning the stored water in the storage facility 2 to the sewer pipe 1, and a stored water discharge port 9 serving as an outlet for the returned stored water to the sewer pipe 1. The return means 8 is controlled by the signal from the control means 4. The stored water discharge port 9 is provided upstream of the water quality measuring means 5.

The present embodiment is a method of treating diluted water in which after the bad sewage ends and the storage of the sewage is stopped, the stored bad sewage is diluted with the sewage flowing in the sewer pipe 1. In this embodiment, since the mixed water of the bad sewage and the sewage passes through the water quality measuring means 5, the water quality measuring means 5 monitors the water quality value of the mixed water by the control means 4 so as to be equal to or lower than the reference value.

The control means 4 receives the water quality information A of the water quality measuring means 5 and controls the flow rate F of the returning means 8 so that the water quality of the mixed water falls within a preset reference value, and the malicious sewage is sewered. 1 to prevent discharge.

When a pH meter is used as the water quality measuring means 5, the range between the lower limit value AL and the upper limit value AH of the reference value is 5.8.
It is recommended to set it to ~ 8.6. It has a lower limit AL of 5.
The reason for lowering to 8 or less is that the acidity is too strong and the organic substances are removed by the microorganisms used in the sewage treatment plant, but the microorganisms die and the metal used downstream is deteriorated. is there. Also, if the upper limit value AH is 8.6 or more, the alkalinity is too strong and the same drawbacks as described above occur.

The control flow of this embodiment shown in FIG. 4 will be described with reference to FIG.

First, in step S1, the control means 4 activates the returning means 8 to start returning the stored water. Returning means 8
The flow rate F of is preferably set to a value as small as possible.

Next, in step S2, it is determined whether the water quality information A is in the range of the lower limit value AL or more and the upper limit value AH or less. For the water quality information A, it is advisable to consider the delay in the time when the returned stored water reaches the water quality measuring means 5. If the water quality information A is within the range of the lower limit value AL or more and the upper limit value AH or less, the process proceeds to step S3, and if it is out of the range, the process proceeds to step S7.

In step S3, the flow rate F is the maximum flow rate F.
It is determined whether it is H or less. When the flow rate F reaches the maximum flow rate FH, the process ends. When the flow rate F is less than or equal to the maximum flow rate FH, the process proceeds to step 4. In step S4, the flow rate F is increased by a fixed amount (ΔF), and the process proceeds to step S5. In step S5, it is determined whether the water quality information A is in the range of the lower limit value AL or more and the upper limit value AH or less. If it is within the range, the process returns to step S3, and if it is out of the range, the process proceeds to step 6.

In step S6, the flow rate F is kept constant (Δ
F) Decrease and end. The decrease amount of the flow rate F is determined by
It is equal to the increment of 4. In step S6, step S
Since the flow rate increased in 4 is returned to the original value, the water quality can be in the range of the lower limit value AL or more and the upper limit value AH or less.

In step S7, the flow rate F is the minimum flow rate FL.
It is determined whether the above. When the flow rate F is equal to or higher than the minimum flow rate FL, the process proceeds to step S8, and when the flow rate F reaches the minimum flow rate FL, the process proceeds to step S10.

In step S8, the flow rate F is kept constant (Δ
F) Decrease and shift to step S9. In step S9, it is determined whether the water quality information A is in the range of the lower limit value AL or more and the upper limit value AH or less. If it is within the range, the process ends, and if it is outside the range, the process returns to step S7. In step S10, the returning means 8 is stopped.

Next, in step S11, the storage facility 2
Store a certain amount of sewage inside. Since the water quality value of the combined water does not meet the standard even at the minimum flow rate FL, the sewage is stored and the malicious sewage is diluted in the storage facility 2. Then, step S1 again
Return to. A stirring means may be provided in the storage facility 2 as needed.

Since the flow rate and the water quality of the sewage change, the flow rate F of the mixed water needs to be appropriately changed in order for the mixed water to satisfy the reference value of the water quality value. Therefore, this control flow is
It should be carried out not only at the start of return but also periodically during return. It should be noted that the process is performed from step S2 during the return.

As described above, according to the present invention, when the bad sewage occurs, the bad sewage is stored in the storage facility 2, and after the end of the bad sewage, the stored bad sewage and the sewage are diluted with a flow rate ratio satisfying the standard value of the water quality. While diluting water can be discharged. As a result, it is possible to prevent damage such as damage to sewer facilities and deterioration of functions due to the flow of malicious sewage. In addition, it is possible to effectively use rainwater storage facilities that were not used except during rainfall.

That is, when the water quality value from the water quality measuring means is detected to be equal to or lower than the reference value, the control means controls the flow rate of the stored water from the returning means so as to maintain the water quality value of the sewage at the reference value. To release as.

If the return means 8 and the stored water discharge port 9 are installed in the sewer pipe 1 on the upstream side of the water quality measuring means 5, the diluted water in which the bad sewage of the storage facility 2 is mixed with the sewage has a standard value. Whether or not there is a cage can be reliably detected by one water quality measuring means 5. Further, when the dilution water detects the reference value or more, the control means 5 closes the intake means 3 and the dilution water having the reference value or more can be retained in the storage facility 2 without being drained downstream again. Can be achieved.

Further, water quality measuring means 5 and 5A for measuring the water quality are installed in the sewer pipe 1 and the storage facility 2, respectively, and the stored water quality measuring means is determined from the water quality value in the sewer pipe from the water quality measuring means 5. When the water quality value of the stored water in the storage facility 2 is detected to be lower than the standard value by 5A, the control means 4 controls the flow rate of the stored water from the returning means 8 so that the water quality value of the sewage becomes lower than the standard value. If controlled and released as dilution water, resources can be used effectively. (Embodiment 4) FIG. 6 shows an embodiment similar to FIG. In this embodiment, the stored water discharge port 9 is provided downstream of the water quality measuring means 5. Further, the water quality measuring means 5 is provided downstream of the stored water discharge port 9.

The water quality information of the stored water quality measuring means 21 is transmitted to the control means 4. As the stored water quality measuring means 21, it is desirable to use the same measuring device as the water quality measuring means 5.
Moreover, you may provide the means to stir the inside of the storage facility 2 as needed.

Based on the water quality information from the water quality measuring unit 5, the control unit 4 controls the intake unit 3 to control the intake unit 3 when the quality of the sewage is equal to or higher than the preset upper limit value or lower than the preset lower limit value. Store in 2. Next, the control means 4 injects the medicine with the medicine supply means 20. The control means 4 stops the medicine supply of the medicine supply means 20 when the water quality information of the stored water quality measuring means 21 falls within the range between the preset lower limit value and upper limit value. Next, the control means 4 activates the return means 8 to return the stored water in the storage facility 2 to the sewer pipe 1.
