Nondestructive regeneration treatment process for PCB tin stripping wastewater and treatment device thereof

Abstract

The invention relates to the technical field of wastewater treatment, in particular to a nondestructive regeneration treatment process for PCB tin stripping wastewater and a treatment device thereof. The device comprises a treatment pond and a dosing cylinder, a control table is arranged at the upper end of the center of the treatment pond, a first reaction pond, a second reaction pond and a third reaction pond are sequentially formed in the three sides of the control table of the treatment pond, and the upper ends of the first reaction pond, the second reaction pond and the third reaction pond are each provided with an annular groove. According to the device, a plurality of treatment procedures are concentrated together for treatment, so that the situation that the loss of tin stripping wastewater is aggravated while the labor force is increased and the transfer among various treatment processes is increased is prevented. Meanwhile, the device is not large in size and can be arranged indoors, and extra loss caused by sun grilling during treatment is prevented; a control seat is used for controlling a shower head to be always kept below the horizontal plane of supernate; and meanwhile, an annular plate rotates to improve the mixing efficiency between liquid medicine and wastewater during dosing, and the reaction time is shortened.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a non-destructive regeneration treatment process and a treatment device for PCB tin stripping wastewater. Background technique [0002] Tin stripping water is commonly used in the electronics industry. After being used, the tin stripping water contains a large amount of tin metal and cannot be discharged without treatment. At the same time, tin stripping wastewater can continue to be used after corresponding treatment, but now In the existing technology, in the process of tin stripping wastewater treatment, the treatment process is relatively slow, and there are many processing processes at the same time, and the treatment efficiency is slow, and a large amount of tin stripping wastewater will be lost during multi-process conversion, resulting in unnecessary losses. Contents of the invention [0003] The object of the present invention is to provide a treatment dev...
