Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0058] Figure 1 FIG. 1 is a structural diagram of a storage and treatment device provided by an embodiment of the present invention. Figure 1 , a storage and treatment device for overflow pollution, comprising:

[0059] A water inlet unit 101, a plurality of first electrically-controlled valves 102, a regulating storage tank 103 provided with a plurality of parallel regulating storage processing units 1031, a plurality of liquid level gauges 1032, a plurality of second electrically-controlled valves 104, a second drainage structure 105, a first drainage structure 106 and an intelligent controller 107; wherein, the correspondence between the first electrically-controlled valves and the regulating storage processing units, and the correspondence between the second electrically-controlled valves and the regulating storage processing units are both preset, and the corresponding regulating storage processing unit can be determined according to the internal number of the first electrically-controlled valve, and similarly, the corresponding regulating storage processing unit can also be determined according to the internal number of the second electrically-controlled valve, and similarly, the corresponding first electrically-controlled valve or second electrically-controlled valve can also be determined according to the regulating storage processing unit.

[0060] The water inlet unit 101 is connected to the regulating and storing treatment unit 1031 through the first electrically-controlled valve 102; the water inlet unit 101 introduces the overflow sewage into the regulating and storing treatment unit 1031; wherein, the number of the first electrically-controlled valves must be greater than or equal to the number of the regulating and storing treatment units to ensure that one regulating and storing treatment unit corresponds to at least one first electrically-controlled valve.

[0061] The regulating and storing treatment unit 1031 is connected to the first drainage structure 106 through the second electrically-controlled valve 104, and is used to store sewage and perform sedimentation treatment to obtain supernatant and sedimentation concentrate, and discharge the supernatant into the first drainage structure 106 through the second electrically-controlled valve 104; similarly, the number of second electrically-controlled valves must be greater than or equal to the number of regulating and storing treatment units to ensure that one regulating and storing treatment unit corresponds to at least one second electrically-controlled valve.

[0062] The first drainage structure 106 discharges the supernatant to the ecological treatment facility 110;

[0063] The second drainage structure 105 is connected to the storage and treatment unit 1031 and is used to discharge the precipitated concentrated liquid into the sewage treatment plant 109;

[0064] The liquid level meter 1032 is arranged in the regulating and storing treatment unit 1031, and is used to detect the sewage liquid level in the regulating and storing treatment unit 1031. In the present application, the liquid level meter uses an ultrasonic liquid level meter. It should be noted that the type of liquid level meter in the regulating and storing treatment equipment in the present application is not limited to the ultrasonic liquid level meter, and other types of liquid level meters can also be selected according to the needs.

[0065] The intelligent controller 107 is respectively connected to the first electrically-controlled valve 102, the liquid level meter 1032, the second drainage structure 105 and the second electrically-controlled valve 104, and is used to receive the sewage level sent by the liquid level meter 1032, control the opening and closing of the first electrically-controlled valve 102 according to the sewage level, and control the opening and closing of the second electrically-controlled valve 104 and the second drainage structure 105 when the set conditions are met.

[0066] In detail, the above-mentioned setting conditions include the opening and closing conditions of the second electric-controlled valve and the opening and closing conditions of the second drainage structure.

[0067] The second electronically controlled valve opening and closing conditions are further divided into a second electronically controlled valve opening preset condition and a second electronically controlled valve closing preset condition.

[0068] The preset condition for opening the second electrically controlled valve is: when the sewage level in the regulating and storage treatment unit corresponding to the second electrically controlled valve reaches the first preset level, and the hydraulic retention time of the sewage in the unit exceeds the set time. The set time here can be determined according to the purification capacity of the regulating and storage tank. When an enhanced physical and chemical treatment structure is provided in the regulating and storage treatment unit, the hydraulic retention time of the sewage will be shorter. If an enhanced physical and chemical treatment structure is not provided in the regulating and storage treatment unit, the sewage can only settle freely, and the hydraulic retention time will be longer. The set time in this application is set to a minimum of 15 minutes and a maximum of 120 minutes. It should be noted that the selection of the set time here is not unique, and can be set according to actual conditions, and does not rule out the possibility of shortening the hydraulic retention time as technology develops.

[0069] The preset closing condition of the second electrically controlled valve is to close the second electrically controlled valve when the sewage liquid level detected by the liquid level meter reaches a second preset liquid level. The second preset liquid level here is lower than the first preset liquid level.

[0070] The opening and closing conditions of the second drainage structure specifically include: when the supernatant in the regulating and storage processing unit is drained, that is, the second drainage structure is opened after the second electric control valve is closed; when the sedimentation concentrate in the regulating and storage processing unit is drained, the second drainage structure is closed. How to judge whether the sedimentation concentrate has been drained here can be set according to specific circumstances, for example, when the liquid level detected by the liquid level meter is lower than a certain value, it is determined that the sedimentation concentrate has been drained, or after a certain period of time, it is determined that the sedimentation concentrate has been drained.

[0071] In more detail, the water inlet unit 101 includes: a water inlet pipe 1011 and a water inlet tank 1012;

[0072] The water inlet pipe 1011 is connected to the water inlet tank 1012 and is used to introduce the overflow sewage into the water inlet tank 1012. The water inlet tank 1012 is connected to the storage and treatment unit 1031 through the first electric control valve 102.

[0073] The first drainage structure 106 includes a drainage groove 1061 and a first drainage pipe 1062;

[0074] The drainage trough 1061 is connected to the first drainage pipe 1062 and is used to discharge the supernatant to the ecological treatment facility 110 through the first drainage pipe 1062 .

[0075] Furthermore, the first drainage structure 106 further includes: a first submersible pump 1063, which is used to introduce the supernatant in the drainage tank 1061 into the first drainage pipe 1062 and then discharge it to the ecological treatment facility 110. The first submersible pump 1063 is also connected to the intelligent controller 107, and is used to receive an opening signal or a closing signal sent by the intelligent controller 107. When the supernatant forms a gravity flow, the first submersible pump 1063 does not need to be turned on. At this time, the intelligent controller 107 sends a closing signal, and vice versa, it sends an opening signal.

[0076] The second drainage structure 105 includes a second submersible pump 1051, a plurality of third electrically controlled valves 1052 and a second drainage pipe 1053;

[0077] The second submersible pump 1051 is arranged in the set storage and regulation processing unit; the third electrically-controlled valve 1052 is arranged on the side wall of the remaining storage and regulation processing units; the sum of the number of the third electrically-controlled valves 1052 and the number of the second submersible pumps 1051 is greater than or equal to the number of the storage and regulation processing units; in the present application, the second submersible pump is arranged in the last storage and regulation processing unit, and at least one third electrically-controlled valve is arranged in other storage and regulation processing units.

[0078] The second submersible pump 1051 discharges the precipitated concentrated liquid to the sewage treatment plant 109 through the second drainage pipe 1053 .

[0079] In more detail, in order to enhance the sewage treatment efficiency in the regulating and storage tank, an enhanced physicochemical treatment structure can be set inside the regulating and storage treatment unit. For example, an inclined plate, an inclined tube, or a flocculant is added inside the regulating and storage treatment unit. A precipitation and dosing device can be selected according to the characteristics of the influent water quality. It should be noted that the specific implementation form of the enhanced physicochemical treatment structure is not unique and is not limited to the above-mentioned structure mentioned in this application.

[0080] On the basis of the above-mentioned embodiment, the storage and treatment equipment of the present application further includes: an overflow pipe 108 connected to the water inlet tank 1012, which is used to discharge overflow sewage that exceeds the treatment capacity of the storage and treatment equipment.

[0081] Taking a storage tank with three parallel storage and treatment units as an example, the working process of the above storage and treatment equipment is introduced. The details are as follows:

[0082] During rainfall, overflow sewage enters the water inlet tank through the water inlet pipe. At this time, the first first electronically controlled valve is opened to allow the overflow sewage to enter the first storage and treatment unit. At the same time, the liquid level meter in the first storage and treatment unit detects the sewage level in the unit in real time. When the sewage level reaches the first preset level, the first first electronically controlled valve is closed, and the second first electronically controlled valve is opened at the same time, so that the overflow sewage enters the second storage and treatment unit. Similarly, when the sewage level in the second storage and treatment unit reaches the first preset level, the second first electronically controlled valve is closed, and the third first electronically controlled valve is opened. The third first electronically controlled valve is closed according to the above principle. In this process, when the first electronically controlled valve of the first storage and treatment unit is closed, and the hydraulic retention time of the sewage in the unit reaches the set time, the second electronically controlled valve corresponding to the first storage and treatment unit is opened, and the supernatant of the overflow sewage after sedimentation flows into the drainage tank through the second electronically controlled valve, and then flows into the ecological treatment facility through the first drainage pipe. According to this principle, the second storage and treatment unit and the third storage and treatment unit also discharge their internal supernatant into the drainage tank, and then finally into the ecological treatment facility. When the supernatant in the three storage and treatment units is completely discharged, the third electrically controlled valve and the second submersible pump are opened to discharge the precipitated concentrated liquid into the sewage pipe network and transport it to the sewage treatment plant. Here, the third electrically controlled valve in the first storage and treatment unit and the third electrically controlled valve in the second storage and treatment unit are opened to connect the three storage and treatment units, and then the precipitated concentrated liquid in the three storage and treatment units is introduced into the sewage treatment plant through the second submersible pump.

[0083] The above-mentioned storage and treatment equipment is equipped with multiple parallel storage and treatment units. The storage and treatment units are connected by batch water intake, sedimentation treatment, and quality-based drainage, which increases the continuous treatment and purification capacity. The mixed flow overflow sewage is enriched and intercepted inside the storage tank to the greatest extent, and the effective volume of the storage tank is fully utilized. The impact effect on the biochemical reaction tank of the sewage treatment plant is reduced, which is conducive to the stable operation of the sewage treatment plant.

[0084] Based on the above embodiments, the storage and treatment equipment in the present application also includes: a level meter arranged in the storage and treatment unit, which is connected to the intelligent controller and is used to detect the height of the settled sludge in the corresponding storage and treatment unit and send the height of the settled sludge to the intelligent controller.

[0085] The intelligent controller is also used to determine whether the height of the precipitated sludge is higher than the preset sludge height. If so, it sends a reminder for the cleaning and maintenance of the storage tank to the intelligent terminal to remind the maintenance personnel to clean it. The intelligent terminal here is not unique, it can be a computer or a mobile phone, and the final choice depends on the actual situation.

[0086] This level meter can be used to monitor the sludge situation inside the storage tank in real time and clean the internal sludge in time.

[0087] In order to more clearly introduce the hardware equipment for implementing the embodiment of the present invention, the embodiment of the present invention also provides a method for regulating and treating overflow pollution. Figure 2 is a flow chart of a storage processing method provided by an embodiment of the present invention. Figure 2 A method for regulating and treating overflow pollution, the method being applied to the above-mentioned overflow pollution regulating and treating equipment, comprising:

[0088] Step 201: obtaining the sewage level sent by the liquid level meter;

[0089] Step 202: Determine the storage processing unit corresponding to the liquid level meter;

[0090] Step 203: Determine the corresponding first electrically-controlled valve and second electrically-controlled valve according to the storage and regulation processing unit; wherein the correspondence between the storage and regulation processing unit, the liquid level meter, the first electrically-controlled valve and the second electrically-controlled valve has been preset, and the corresponding other components can be determined according to any one of the components.

[0091] Step 204: Determine whether the sewage level has reached the first preset level; the first preset level here can be set according to actual conditions, and the specific value setting is not unique. When the sewage level reaches the first preset level, it means that the storage and treatment unit is full of sewage, step 205: control the first electronically controlled valve to close;

[0092] Step 206: Determine whether the preset conditions for opening the second electrically-controlled valve are met; the preset conditions for opening the second electrically-controlled valve are: when the sewage level in the storage and treatment unit corresponding to the second electrically-controlled valve reaches the first preset level, and the hydraulic retention time of the sewage in the unit exceeds the set time.

[0093] Step 207: Open the second electronically controlled valve.

[0094] Step 208: If the sewage level does not reach the first preset level; determine whether the sewage level reaches the second preset level; the second preset level is less than the first preset level; when the sewage level reaches the second preset level, it means that the supernatant in this storage and treatment unit has been drained.

[0095] Step 209: Close the second electronically controlled valve.

[0096] The storage and treatment method in the above embodiment realizes the enrichment and retention of mixed flow overflow pollutants inside the storage and treatment unit to a large extent through sequential batch water inlet and outlet control, fully utilizes the effective volume of the storage tank, purifies the sewage entering the storage tank, and improves the purification effect of the sewage.

[0097] Based on the above embodiments, the storage processing method in this application also includes:

[0098] Obtain the sedimentation sludge height sent by the level meter;

[0099] Determine whether the sedimentation sludge height is higher than the preset sludge height;

[0100] If so, a reservoir cleaning and maintenance reminder is sent to the smart terminal to remind the maintenance personnel to clean it.

[0101] This method can monitor the sludge situation inside the regulating reservoir in real time, clean the internal sludge in time, ensure the normal operation of the regulating reservoir equipment, improve the maintenance efficiency of the regulating reservoir, and realize unmanned automated intelligent control.
