Abstract

The invention relates to the technical field of decolorizing agents, and discloses a novel efficient printing and dyeing wastewater decolorizing agent and treatment equipment thereof. The novel efficient printing and dyeing wastewater decolorizing agent comprises a decolorizing treatment platform and a flocculation decolorizing treatment barrel body, and the flocculation decolorizing treatment barrel body is arranged on the top face of the left end of the decolorizing treatment platform. A decolorizing agent feeding hopper fixedly sleeves the left outer wall of the top end of the flocculation and decolorization treatment barrel body, a stirring rod is arranged above the flocculation and decolorization treatment barrel body, a first filter box is arranged on the right side of the flocculation and decolorization treatment barrel body, and an oxidation and decolorization treatment tank is arranged on the right side of the first filter box. A chlorine generator is arranged in front of the oxidation decolorization treatment tank, a sodium hydroxide solution tank is arranged behind the right side of an ultraviolet spotlight, a second filter box is arranged on the right side of the ultraviolet spotlight, and a reduction disinfection treatment tank is arranged on the right side of the second filter box. Through preparation combination of various raw materials, the effects of efficient flocculation, efficient filtration and efficient water discharge on the printing and dyeing wastewater are effectively realized.

Description

technical field [0001] The invention relates to the technical field of decolorizing agents, in particular to a novel high-efficiency printing and dyeing wastewater decolorizing agent and treatment equipment thereof. Background technique [0002] Printing and dyeing wastewater decolorant is an organic polymer compound polymer, which belongs to the flocculation decolorization water treatment agent. It can deal with a wide range of decolorization, and can effectively reduce COD without affecting the biochemical system. At the same time, it reduces other pollutants in the water body, reduces the chromaticity of sewage, and improves the quality of effluent water. The chromaticity of treated wastewater can meet the national discharge standards, and can be used in factories without secondary pollution. The dosing process is simple and adaptable. Now The printing and dyeing wastewater decolorizing agent of the prior art has the problem of low decolorization treatment efficiency in t...
