Embodiment Construction

[0026] Below in conjunction with accompanying drawing, structure and working process of the present invention will be further described.

[0027] A water-saving system for textile dyeing, including an external controller, at least two sewage treatment tanks and a clean water storage tank, the sewage treatment tanks are connected in sequence, and all the sewage treatment tanks are at different physical heights, each sewage treatment tank There are two filter screens inside, and there is a gap between the two filter screens. The concentration sensor is set on the side wall of the sewage treatment tank, the water inlet is set on the upper part of the sewage treatment tank, and the water outlet is set on the bottom of the sewage tank. Then the first-level sewage treatment tank and connected to the clean water storage tank, controllable valves are set between the sewage treatment tanks and between the sewage treatment tank and the clean water storage tank, the controllable valves ar...

Abstract

The invention discloses a water-saving textile dyeing system which comprises an external controller, at least two sewage treatment tanks and a clean water storage device, wherein the sewage treatment tanks are connected sequentially with one another and are at different physical heights; two filter screens are arranged inside each sewage treatment tank; a gap is reserved between the two filter screens; a concentration sensor is arranged on the side wall of each sewage treatment tank; a water inlet is formed in the upper part of each sewage treatment tank, and a water outlet is formed in the bottom of each sewage treatment tank; the last level of sewage treatment tank is connected with the clean water storage device; controllable valves are arranged between sewage treatment tanks and between the sewage treatment tank and the clean water storage device; the controllable valves are connected with the external controller. The sewage treatment tanks adopt multi-level cascade, and the physical heights are different, so that the sewage after each level of treatment can be discharged to the next stage of sewage treatment tank, no water pump is required, energy sources are reduced, the sewage can be fully and automatically treated, environmental pollution is reduced, and energy is saved.

Description

technical field [0001] The invention belongs to the field of textile water treatment, and in particular relates to a textile dyeing water-saving system. Background technique [0002] There are mainly the following methods for textile dyeing water treatment: [0003] Chemical method: At present, 80% of them use chemical method, but even if the wastewater after chemical treatment meets the discharge standard, there are still pollutants in it, which are easily absorbed and accumulated by animals and plants, and transferred to the human body in the way of food chain. And the discharged water cannot be recycled, nor can it be reused without advanced treatment. Furthermore, the amount of heavy metal-containing sludge after chemical treatment is difficult to handle and easily causes secondary pollution. [0004] Electrolysis: Electrolysis is an effective method to treat wastewater containing high concentrations of electrodeposition. Although the treatment method is relatively mat...
