Embodiment 1

[0029] Embodiment 1: A rotary dye wastewater decolorization device, including a water inlet device, an adsorption plate reaction device, a rotating device, a sediment collection device, and a flushing device; wherein, the water inlet device is mainly composed of a sump 1 through a peristaltic pump 2 Connected to water inlet 3. The main body of the adsorption plate reaction device is a cylindrical reactor with an upper opening. In the reactor, eight adsorption plates 4 are fixed in the slots 7 on the rotating shaft, and the angle between two adjacent groups of adsorption plates 4 is is 45°; the bottom of the cylindrical reactor is an inverted conical sediment collection tank 10. An overflow weir 8 is provided on the upper part of the reactor, and a water outlet 9 is provided on the wall of the overflow weir 8 to connect the outlet water collecting device.

[0030] The rotating device is mainly composed of a drive bearing 5 and a rotating shaft 6; the rotating shaft 6 is locate...

Embodiment 2

[0037] Embodiment 2: Rotary dye wastewater decolorization device, as described in Embodiment 1, the difference is that the weight ratio of red mud and sludge on the adsorption plate is 78:12. The adsorption plate has a decolorization rate of more than 95% for dye wastewater containing acid scarlet.

Embodiment 3

[0038] Embodiment 3: Rotary dye wastewater decolorization device, as described in Embodiment 1, the difference is 80 parts of red mud, 8 parts of sludge, 2 parts of sodium hydroxymethyl cellulose, and 10 parts of water on the adsorption plate. The adsorption plate has a decolorization rate of more than 99% for dye wastewater containing disperse brilliant blue.

Abstract

The invention relates to a rotary dye waste water decolorizing device, which comprises a water feeding device, an adsorption plate reaction device, a rotating device, a precipitate collecting device and a flushing device, wherein the main body of the adsorption plate reaction device is a cylindrical reactor of which the upper part is opened; 4-8 adsorption plates fixed on a rotating shaft clamping groove are arranged in the reactor; the rotating device mainly comprises a rotating shaft and a driving bearing; under the action of driving force, the rotating shaft rotates in the reactor, so that the adsorption plate is fully contacted with dye waste water; and in a rotary adsorption process, a red mud and sludge adsorbent falling off from the surface layer of an adsorption plate is enriched and uniformly treated in the precipitate collecting device. The rotary dye waste water decolorizing device has the advantages of convenience for operating, small occupied space, simple treatment process and solving of the problem of difficulty in treating dye waste water.

Description

technical field [0001] The invention relates to a rotary dye wastewater decolorization device, which belongs to the field of sewage treatment. Background technique [0002] Dye wastewater is wastewater discharged from printing and dyeing factories that mainly process cotton, hemp, chemical fibers and their blended products. Dye wastewater has a large amount of water, 100-200 tons of water is consumed per ton of textile printing and dyeing, of which 80-90% becomes wastewater. Due to the high content of organic matter, deep color, complex water quality and large fluctuations in composition, dye wastewater has become one of the most difficult industrial wastewater to treat. Dye wastewater contains a large amount of organic pollutants, which will consume dissolved oxygen in the water, destroy the ecological balance of the water, and endanger the survival of fish and other aquatic organisms. Organic matter sinking to the bottom of the water will produce harmful gases such as hy...
