A flocculent adsorber applied to the treatment of printing and dyeing wastewater

Abstract

The invention discloses a floc adsorber applied to the treatment of printing and dyeing wastewater, belonging to the technical field of printing and dyeing wastewater treatment. The small impurities in the wastewater can be adsorbed, and the magnetic floating suction balls can also be adsorbed and fixed. Multiple magnetic floating suction balls are used to adsorb the flocs, and in the process of collision with each other, they are inserted into the fiber adsorption bag. The multiple activated carbon adsorption thorns on the top are squeezed inward to pierce the bonding permeation layer, and the bonding permeable layer continuously overflows and distributes on the fiber adsorption bag and the activated carbon adsorption thorns, which is beneficial to improve its adsorption capacity. At the same time, the aeration nozzle With the rotating motion of the U-shaped agitating aeration rack, the aeration direction can be adjusted continuously, which is beneficial to improve the diffusion uniformity of the magnetic floating suction ball, so as to facilitate the more sufficient and fast adsorption treatment of flocs.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing wastewater treatment, and more particularly, to a flocculent adsorber applied to the treatment of printing and dyeing wastewater. Background technique [0002] The production of printing and dyeing enterprises needs to consume a lot of water resources. According to the current normal industrial production level in my country, the annual water consumption reaches tens of millions of tons, and the discharged wastewater generally contains a large amount of cotton yarn, fibers, impurities and other flocs. If not treated, it will cause serious pollution to the ecological environment. [0003] In order to prevent the deposition and blockage of the subsequent treatment unit, a filter device is installed in the wastewater filtration treatment process to intercept fibers and impurities. The commonly used filtering impurities are mostly filtered by a filter screen. Due to the presence of fibers a...

[0002] The production of printing and dyeing enterprises needs to consume a lot of water resources. According to the current normal industry production level in my country, the annual water consumption reaches tens of millions of tons, and the wastewater discharged generally contains a large amount of cotton yarn, fibers, impurities and other flocs. If not treated, it will cause serious pollution to the ecological environment.

[0003] In order to prevent the deposition and clogging of subsequent treatment units, filter devices are installed in the wastewater filtration process to intercept fibers and impurities. Currently, the commonly used filter impurities are mostly filtered by filter screens. Due to the presence of fibers and other flocs in wastewater It is very small, and it is difficult for a filter with a general pore size to fully capture small impurities, and to a certain extent, it still cannot achieve a good filtering effect
