Detailed description of the invention

Embodiment 1

As it is shown in figure 1, a kind of COD stably reaching standard tapping equipment, discharge pond 2 including controller, the first discharge pond 1, second With process pond 5, described first discharge pond 1 and the second discharge pond 2 are arranged in parallel, and the water inlet end in described first discharge pond 1 is provided with First automatically controls actuator 11, and described first discharge water side, pond 1 is provided with second and automatically controls actuator 12, described The water inlet end in the second discharge pond 2 is provided with the 3rd and automatically controls actuator 21, and described second discharge water side, pond 2 is provided with the Four automatically control actuator 22, are provided with COD detector 3 and liquidometer in described first discharge pond 1 and the second discharge pond 2 4, described COD detector 3 and liquidometer 4 are all connected with described controller signals；Described process pond 5 and described first discharge pond 1 Between be provided with the 5th and automatically control actuator 13, be provided with between described second discharge pond 2 and described process pond 5 the 6th from Dynamic control actuator 23.Described controller is used for controlling the described first, second, third, fourth, the 5th and the 6th and automatically controls The keying of actuator 11,12,21,22,13,23, the first described discharge pond 1 water inlet end and the second discharge pond 2 water inlet end are equal Connecting with water inlet pipe 8, described water inlet pipe 8 connects with described process pond 5, and described water inlet pipe 8 is provided with feed pump 6 and effusion meter 7。

Described the first, second, third, fourth, the 5th and the 6th automatically controls actuator 11,12,21,13,23 and is Electrodynamic valve or pneumatic operated valve, in the present embodiment as a example by electrodynamic valve.

Specifically, for improving mass rate of emission, the water inlet end caliber in the first described discharge pond 1 is less than its water side caliber, Described second discharge pond 2 water inlet end caliber is less than its water side caliber.

Operation principle is as follows: controller control first automatically controls actuator 11 and opens, and other automatically control execution machine Structure is closed, as in figure 2 it is shown, the water handled well in processing pond 5 pumps into the first discharge pond 1 through water inlet pipe 8, when in first row tank Liquidometer 4 detects after liquid level reaches predetermined fluid level L, and signal is passed to controller, and now, COD detector 3 carries out detecting COD of sewage concentration in one discharge pond 1, meanwhile, controller controls first and automatically controls actuator 11 and cut out, the 3rd automatically control Actuator 21 is opened, and the water inlet used time is T1, and the water after feed pump 6 processes in will processing pond 5 pumps into the second discharge pond 2；The After COD detector 3 in one discharge pond 1 has detected, the detection used time is T2, and signal is passed to controller, if the first discharge In pond 1, COD is up to standard, then controller controls second and automatically controls actuator 12 and open, and carries out draining, and the draining used time is T3, if The most up to standard, then controller controls the 5th and automatically controls actuator 13 and open, and water enters process pond 5 and again processes, and draining is used Time be T3, after discharge controller control second or the 5th automatically control actuator 12,13 close；Pond 1 is discharged first Interior COD detection and after draining completes, the used time is T2+T3, and in the second discharge pond 2, water inlet also reaches predetermined fluid level, and the water inlet used time is T1, signal is passed to controller by the liquidometer 4 in the second discharge pond 2, and controller controls the 3rd and automatically controls actuator 21 Close, and open first and automatically control actuator 11 and open, stop water inlet in the second discharge pond 2, carry out in the first discharge pond 1 Second time water inlet, in the second discharge pond 2, COD of sewage in it is detected by COD detector 3 simultaneously, and the detection used time is T2, if the In two discharge ponds 2, COD is up to standard, then controller controls the 4th and automatically controls actuator 22 and open, and carries out draining, and water discharge time is T3, if the most up to standard, then controller controls the 6th and automatically controls actuator 23 and open, and sewage enters process pond 5 and heavily carries out Processing, water discharge time is T3.After the second discharge pond 2 carries out COD detection and draining completes, the used time is T2+T3, the first discharge pond 1 intakes and reaches predetermined fluid level.So circulation, it is ensured that T1 >=T2+T3, feed pump 6 can work continuously, it is achieved serialization goes out automatically Water, ensures that COD of sewage stably reaches, marks discharge simultaneously.

Should be appreciated that specific embodiment described above is only used for explaining this utility model, be not used to limit this reality With novel.The obvious change extended out by spirit of the present utility model or variation are still in protection of the present utility model Among scope.
