Abstract

The invention relates to a method for in site reduction of a passivation solution carried by an electrolytic manganese negative plate. The device used in the invention comprises a drop brushing device component, a passivation groove, the negative plate and a lifting device, wherein the drop brushing device component is positioned at the top of the passivation groove and is fixedly connected with the passivation groove, the negative plate is positioned above the passivation groove, and the lifting device is positioned above the negative plate and is connected with the negative plate to drive the negative plate to move upwards and downwards. The method comprises the steps of passivation, discharge and drop brushing. Through the utilization of the method provided by the invention, the problems of waste water chromium pollution and the waste of chromium resource are solved, and the passivation solution carried by the negative plate and flowing into a waste water system is greatly reduced.

Description

technical field [0001] The invention relates to a method for in-situ reduction of passivation solution carried by electrolytic manganese cathode plates, in particular to a device for in-situ reduction of passivation solution and a method for in-situ reduction of passivation solution carried by electrolytic manganese cathode plates by using the device. Background technique [0002] The passivation process in the follow-up electrolysis of the traditional electrolytic manganese industry is manual. The electrolytic manganese cathode plate is placed in the passivation tank filled with potassium dichromate passivation solution by driving. After the passivation is completed, it is directly lifted out and placed on the cathode plate. On the vehicle, the passivation liquid carried by the cathode plate drops on the ground and finally enters the wastewater, causing chromium pollution in wastewater and waste of chromium resources. The passivation process is one of the important pollutio...
