Hydrometallurgy wastewater treatment device and treatment process thereof

Abstract

The invention discloses a hydrometallurgy wastewater treatment device and a treatment process thereof. The device comprises a stirring tank, the lower end of the stirring tank is in sealed connection with a filtering tank through a communicating pipe, the communicating pipe is provided with a control valve, the side wall of the upper end of the stirring tank is fixedly connected with a rotating motor, and an output shaft of the rotating motor penetrates through the side wall of the stirring tank. The position where the output shaft of the rotating motor is connection with the side wall of the stirring tank is in a sealed rotation connection way, the output shaft of the rotating motor is fixedly connected with a main stirrer, and the inner wall of the stirring tank is fixedly connected with a sliding rail through a plurality of first fixing blocks. According to the device, wastewater which is being treated in the stirring tank can be fully and uniformly stirred, so that the wastewater fully reacts with a treatment agent, the phenomenon that substances in the wastewater are not completely precipitated due to insufficient stirring is avoided, the treatment effect is ensured, meanwhile, the filtering speed is increased in a vibration mode, the working efficiency is improved, and wastewater discharge is ensured to reach the standard.

Description

technical field [0001] The invention relates to the technical field of hydrometallurgical wastewater treatment, in particular to a hydrometallurgical wastewater treatment device and a treatment process thereof. Background technique [0002] There are many products in the metallurgical industry, and the production processes are in series. A large amount of waste water is discharged, which is one of the main waste water that pollutes the environment. The problem of waste water pollution in the process of rare earth hydrometallurgy has attracted attention from all sides. The raw materials of rare earth hydrometallurgy in my country are mainly Mixed ores of bastnaesite, bastnaesite and monazite (hereinafter referred to as mixed rare earth concentrates) and ion-adsorbed rare earth ores in Guangdong, Jiangxi and other places, as long as rare earth hydrometallurgy is involved, almost always produce ammonia nitrogen wastewater, ammonia nitrogen Wastewater treatment has always been the...
