Device for treating dirt material of printing and dyeing wastewater

Abstract

The invention discloses a device for treating dirt materials of printing and dyeing wastewater. The device comprises a grid treatment tank, a filtering tank, an aeration treatment tank, a pool, an ejector, an ozone generator, a releaser, a water pump A, a water pump B and a water pump C, wherein a grid net is arranged inside the grid treatment tank; a water inlet tube is arranged on the left side of the grid net; a first water tube is arranged on the right side of the grid net; the first water tube is communicated with the filtering tank; the water pump A is arranged on the first water tube; a plurality of baffle plates are arranged from left to right in a staggered manner on the inner walls of two sides of the filtering tank; an activated carbon filtering net A is arranged at one end close to one inner wall of the filtering tank, of each baffle; the activated carbon filtering nets A prop against adjacent baffle plates and the inner walls of the filtering tank; and one side far away from the grid treatment tank, of the filtering tank, is communicated with the left side of the aeration treatment tank through a second water tube. By adopting the device, the activated carbon filtering nets can be highly utilized, and macromolecular organisms can be oxidized by ozone and ultraviolet light.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment device for printing and dyeing sewage. Background technique [0002] The wastewater in textile printing and dyeing enterprises contains a large amount of dyeing auxiliaries, lint, etc., which makes the wastewater present the characteristics of high chroma, high turbidity, and organic matter that is difficult to degrade. Most of the traditional procedures for treating printing and dyeing wastewater use activated carbon suction filtration. However, the setting method of activated carbon is unreasonable, the utilization rate is not high, and the effect of filtering by activated carbon alone is also poor, which is far from reaching the standard. Contents of the invention [0003] The object of the present invention is to propose a treatment device for printing and dyeing sewage in order to solve the shortcomings in the prior art. [0004] In order to achieve t...
