Abstract

The invention discloses a complete device for reusing dyeing rinsing water with high quality. The complete device is characterized by comprising a baffling reactor, a circulating slot, a tubular membrane element filtering tank and an ion exchange device which are sequentially connected with a rinsing slot of a dyeing machine; an advanced oxidizing agent adding device is arranged on a pipeline in frontof the baffling reactor; the tubular membrane element filtering tank comprises a tank body; a water inlet, a water production port and a dense water outlet are formed in the tank body; a tubular membrane element is arranged in the tank body; the concentrated water outlet is connected with the circulating slot through a reflux pipeline; the water production port is connected with the ion exchange device or connected with a dyeing slot of the dyeing machine; and the water production port of the ion exchange device is connected with the dyeing slot of the dyeing machine. The invention also discloses a clean production process for reusing dyeing rinsing water with high quality by adopting the complete device. The complete device and the clean production process can meet reusing requirements when being used for rinsing water treatment.

Description

technical field [0001] The invention relates to the field of dyeing and rinsing water treatment, in particular to a clean production process and a complete set of equipment for high-quality reuse of dyeing and rinsing water. Background technique [0002] The printing and dyeing industry is an industry that consumes a large amount of water in the textile industry, and water is used as a medium to participate in the entire dyeing and finishing process. Printing and dyeing wastewater has a large amount of water, high chroma, and complex components. The wastewater contains dyes, pastes, additives, oils, acids and bases, fiber impurities, and inorganic salts. In the structure of dyes, nitro and amino compounds and copper, chromium, Heavy metal elements such as zinc and arsenic have high biological toxicity and seriously pollute the environment. [0003] The main pollutants in dyeing wastewater are dyes and auxiliaries. Because different fiber raw materials and products need to ...
