[0002] The wastewater generated by various enterprises when producing printed circuit boards is collected and regulated, and finally gathered in the wastewater treatment pool of the sewage treatment plant. After a series of chemical treatments, it is discharged only after meeting the water quality discharge standards.

[0003] During the dosing treatment process, various reagents are located in corresponding reagent pools respectively. Each reagent pool corresponds to a wastewater treatment pool. A pipeline is connected between the reagent pool and the corresponding wastewater treatment pool. A water pump and a one-way valve are connected to the pipeline. After the wastewater flows into a wastewater treatment pool, the water pump and the one-way valve on the pipeline between the corresponding reagent pool and the wastewater treatment pool are opened, and the liquid medicine in the corresponding reagent pool flows to the wastewater treatment pool, completing a link in the wastewater treatment.

[0004] A water pump needs to be installed between each reagent pool and the wastewater treatment pool. Since there are multiple reagent pools and corresponding wastewater treatment pools, multiple water pumps need to be installed, and the equipment installation and maintenance costs are high.

[0006] The technical solution adopted by the utility model is as follows: a wastewater treatment dosing system, including a controller for controlling the start and stop of a water pump and a one-way valve, a pharmaceutical device for storing a plurality of pharmaceuticals, and a plurality of wastewater treatment pools arranged and connected in sequence, the pharmaceutical device including a plurality of pharmaceutical pools, a first pipeline is provided between each pharmaceutical pool and the corresponding wastewater treatment pool, a first one-way valve is provided on each of the first pipelines, each of the pharmaceutical pools is located at a high position above the wastewater treatment pool, a first liquid level sensor for monitoring the water level is provided in each of the wastewater treatment pools, a second pipeline is provided between two adjacent wastewater treatment pools, a first water pump and a second one-way valve are provided on each of the second pipelines, and the first liquid level sensor, the first one-way valve, the first water pump, and the second one-way valve are all connected to the controller;

[0007] The controller is used to control the start and stop of the first one-way valve, the first water pump, and the second one-way valve according to the water level height of the wastewater treatment tank. The first liquid level sensor monitors that the wastewater water level in the wastewater treatment tank reaches a first specified height, and the controller controls the first one-way valve to open. The liquid medicine in the reagent pool relies on its own gravity to flow to the corresponding wastewater treatment tank. The first liquid level sensor monitors that the wastewater water level in the wastewater treatment tank reaches a second specified height, and the controller controls the first one-way valve to close.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] The position of the reagent pool of the utility model is higher than that of the wastewater treatment pool, so that when the reagent in the reagent pool flows to the wastewater treatment pool, it can freely fall by its own gravity and enter the corresponding wastewater treatment pool, so that there is no need to set a water pump on the first pipeline between the reagent pool and the wastewater treatment pool, that is, the setting of the water pump is reduced, thereby also reducing the equipment installation and maintenance costs; the controller, the first liquid level sensor, the first one-way valve, the first water pump and the second one-way valve cooperate to control the liquid in the reagent pool to automatically flow to the wastewater treatment pool, and the wastewater flows through different wastewater treatment pools in sequence.

[0010] As a preferred embodiment of the utility model, it also includes a drug delivery device for supplying multiple drugs, the drug delivery device includes multiple drug delivery pools, each of the drug delivery pools is provided with a second liquid level sensor, each of the drug delivery pools is provided with a third pipeline between the corresponding drug delivery pool, each of the third pipelines is provided with a second water pump and a third one-way valve, and the second liquid level sensor, the second water pump, and the third one-way valve are all connected to the controller;

[0011] The controller is used to control the start and stop of the second water pump and the third one-way valve according to the water level height of the medicine pool. The second liquid level sensor monitors that the water level of the medicine pool reaches the third specified height. The controller controls the second water pump and the third one-way valve to open, and the medicine in the medication pool flows to the corresponding medicine pool. The second liquid level sensor monitors that the water level of the medicine pool reaches the fourth specified height. The controller controls the second water pump and the third one-way valve to stop working, and the medicine pool completes the replenishment of the medicine liquid.

[0012] Beneficial effect: The controller, the second liquid level sensor, the second water pump and the third one-way valve cooperate to ensure automatic replenishment of the liquid in the reagent tank.

[0013] As a preferred embodiment of the utility model, a stirring component for stirring sewage is provided in the wastewater treatment tank.

[0014] Beneficial effects: The stirring component can ensure that the reagent and wastewater are fully and evenly mixed, thereby improving the treatment efficiency of the wastewater dosing process.

[0015] As a preferred embodiment of the utility model, the wastewater treatment pool is provided with a shielding cover, and the shielding cover is connected to the first pipe.

[0016] Beneficial effects: The shielding cover prevents the liquid from splashing, effectively seals the wastewater treatment pool, prevents people from falling into the wastewater treatment pool, and improves safety.

[0017] As a preferred embodiment of the utility model, the stirring assembly includes a rotating shaft and a first stirring member, both ends of the rotating shaft are rotatably connected to the side walls of the wastewater treatment tank, the first stirring member includes symmetrically arranged turntables, the two turntables are fixedly connected to the rotating shaft, and a plurality of stirring blades are circumferentially spaced between the two turntables, one end of the stirring blade is connected to the rotating shaft, and the two sides are respectively connected to the corresponding turntables, and the connection point between the first pipeline and the wastewater treatment tank is located directly above the two turntables and directly between the two turntables.

[0018] Beneficial effect: The rotating shaft, two rotating disks and multiple stirring blades cooperate so that the first stirring member can not only stir the wastewater, but also serve as a waterwheel. Since the chemical pool is located high above the wastewater treatment pool, and the connection between the first pipeline and the wastewater treatment pool is located directly above the two rotating disks and directly between the two rotating disks, when the medicine liquid in the chemical pool flows to the wastewater treatment pool through the first pipeline, the potential energy of the medicine liquid itself is converted into the kinetic energy of the first stirring member. Since the first stirring member has the structure of a waterwheel, when the medicine liquid falls between the two stirring blades and the two rotating disks, the medicine liquid drives the first stirring member to rotate, that is, in the absence of power supply, the potential energy of the medicine liquid itself is fully utilized to rotate the first stirring member, so that the medicine liquid and the wastewater are fully mixed and stirred.

[0019] As a preferred embodiment of the utility model, the wastewater treatment tank is provided with a motor, and a pair of meshing gears are provided between the motor and the rotating shaft.

[0020] Beneficial effect: It can ensure that the first stirring member rotates continuously, so as to fully mix and stir the reagent and wastewater in the wastewater treatment tank.
