Abstract

A bleaching and dyeing wastewater treatment device comprises a filtering tank, a stirring tank and a purification tank which are sequentially communicated through a pipeline. A first stirrer and a second stirrer are installed in the stirring tank, the first stirrer is installed at the front position of the left side in the stirring tank, the second stirrer is installed at the rear position of the right side in the stirring tank, the first stirrer and the second stirrer are the same in structure and each comprise a vertically-arranged stirring shaft with the upper portion being cylindrical and the lower portion being conical, the upper parts of the stirring shafts upwards penetrate out of the top surface of the stirring tank, spiral stirring blades are wound on the conical outer walls of the lower parts of the stirring shafts, first helical gears are fixedly arranged at the tops of the stirring shafts, and a motor is arranged above the top surface of the stirring tank and is connected with a second helical gear meshed with the first helical gears. A first purification layer and a second purification layer are mounted in the purification tank and are connected up and down. According to the bleaching and dyeing wastewater treatment device, the stirring tank is reasonable in structure and good in stirring effect.

Description

technical field [0001] The invention relates to the technical field of bleaching and dyeing wastewater treatment, in particular to a bleaching and dyeing wastewater treatment device. Background technique [0002] Bleaching and dyeing is the process of reprocessing textile materials, including four processes of pretreatment, dyeing, rinsing and finishing. The wastewater generated during the bleaching and dyeing process is mainly composed of pretreatment residual liquid, pretreatment cleaning water, dyeing residual liquid, dyeing cleaning water and other parts. Bleaching and dyeing wastewater has a high concentration of organic pollutants, complex components, and high chroma, and is one of the more difficult organic wastewater to treat. The current bleaching and dyeing sewage treatment methods or treatment equipment include mixing technology or mixing equipment. Most of the existing mixing equipment only installs mixing impellers in the mixing tank, and generates unidirection...
