[0017] The technical solution adopted in this utility model is: a multi-chemical wastewater treatment dosing system that is easy to operate and maintain, such as... Figure 1 As shown, the system includes a multi-pharmaceutical storage and maintenance unit 1, which comprises at least two independent pharmaceutical storage tanks 1A. The multi-pharmaceutical storage and maintenance unit 1 also includes a heating and insulation layer 11 installed on the outer wall of each pharmaceutical storage tank 1A, with a temperature sensor 12 installed inside the heating and insulation layer 11. An automatic feeding pipe 1B is also installed at the top of each pharmaceutical storage tank 1A, and a solenoid valve 7 is installed on the automatic feeding pipe 1B. A level sensor 8 connected to the solenoid valve 7 is also installed inside each pharmaceutical storage tank 1A. An anti-clogging dosing unit 2 is also installed at the bottom of each pharmaceutical storage tank 1A, comprising a dosing branch pipe 21 connected to the bottom of each pharmaceutical storage tank 1A, and a main dosing pipe 22 connected to all the dosing branch pipes 21.

When it is lower than the threshold, the controller opens the corresponding solenoid valve 7 to replenish the agent. After reaching the standard, it closes; Anti-clogging dosing: The operator sets the agent ratio, and the controller controls the metering pump 23 to deliver the agent. The agent is transported through the branch pipe and the main pipe. The self-cleaning filter 3 filters impurities. When the branch pipe is blocked (pressure exceeds the standard), the controller turns off the metering pump 23 and turns on the backwash pump 10 to clean it; Ultrasonic mixing: The agent and wastewater enter the mixing tank 41. The controller adjusts the frequency of the ultrasonic vibrator 42 according to the agent solubility and opens the drain valve 45 periodically to drain the sediment; Discharge and monitoring: After the mixing reaches the standard, the discharge valve 6 is opened to discharge the wastewater. The temperature, liquid level and valve status are monitored throughout the process, and an alarm is issued when there is an abnormality.
