[0003] Currently, when treating electroplating wastewater, usually only one or two substances can be treated by the same device, resulting in poor response to the situation where there are many impurities to be treated in the sewage. When treating multiple substances, multiple device structures need to be configured to repeatedly precipitate, filter and other steps for heavy metal ions and other impurities, resulting in a large overall volume of the treatment system, increasing the cost of wastewater treatment, occupying a large amount of space, and at the same time, due to the cumbersome treatment process and long time, it is difficult to effectively improve the treatment capacity of the treatment system.

The bottom of each dosing tank is respectively provided with a dosing port. A switch baffle is installed at the dosing port. The bottom of the reaction sedimentation tank is connected with a sediment collection tank.
[0008] Further, a dosing button is installed on the top of each dosing tank of the multi-type dosing device. The bottom of the dosing button is connected with a dosing rod. The dosing rod is installed inside the dosing tank. The bottom end of the dosing rod is fixedly connected with the switch baffle. A spring mounting plate is also installed on the dosing rod. A return spring is connected between the spring mounting plate and the bottom surface inside the dosing tank. The return spring is sleeved on the dosing rod.
