Device for treating wastewater of nonferrous metal processing

Abstract

The invention discloses a non-ferrous metal processing wastewater treatment device, which comprises an oxidation sedimentation tank and a filter stirring tank. The oxidation sedimentation tank and the filter stirring tank are connected through a No. 1 water pipe, and a water inlet pipe is provided on one side of the oxidation sedimentation tank. A flow meter is arranged on the water inlet pipe, a medicine box is arranged above the oxidation sedimentation tank, and a medicine outlet is arranged at the lower end of the medicine box. In the present invention, by connecting the oxidation sedimentation tank and the filtration and stirring tank through the No. 1 water pipe and the No. 2 water pipe, the water after the initial precipitation in the oxidation sedimentation tank can be introduced into the filtration and stirring tank through the No. 1 water pipe for stirring and filtering, and then the stirring The filtered water is introduced into the peroxidation sedimentation tank through the No. 2 water pipe, and the medicine is added for oxidation and neutralization, and then returned to the filter stirring tank for stirring and filtering, and the sewage purification effect is improved by repeated purification by using the oxidation sedimentation tank and the filter stirring tank Good, and at the same time, the structure is simple and the occupied area is saved.

Description

technical field [0001] The invention relates to a wastewater treatment device, in particular to a nonferrous metal processing wastewater treatment device. Background technique [0002] The production and processing of non-ferrous metals will produce a large amount of wastewater, which contains a large amount of harmful substances. If it is discharged outside, it will cause serious harm to the surrounding ecological environment. If it is returned to the process for recycling, the harmful substances in the wastewater will continue to accumulate, which will It will have adverse effects on the production process and equipment. Therefore, it is necessary to choose an appropriate treatment method to treat the flotation wastewater. [0003] At present, the commonly used wastewater treatment device has a large structure, a large floor area, and complicated operation. It is not used in small factories, and the filtration of wastewater in the wastewater treatment process is not compre...

[0002] The production and processing of non-ferrous metals will produce a large amount of wastewater, which contains a large amount of harmful substances. If it is discharged outside, it will cause serious harm to the surrounding ecological environment. If it is returned to the process for recycling, the harmful substances in the wastewater will continue to accumulate, which will It has adverse effects on the production process and equipment, therefore, it is necessary to choose an appropriate treatment method to treat the flotation wastewater

[0003] At present, the commonly used wastewater treatment device has a large structure, a large floor area, and complicated operation. It is not used in small factories, and the filtration of wastewater in the wastewater treatment process is not comprehensive enough, and the purification effect is not good, and most of the treated wastewater It is not disinfected, and some disinfection processes, the disinfection effect is not good
