Abstract

The invention relates to a waste water processing medicine capable of realizing high efficiency decolouring, decyanation, and degradation of COD. The waste water processing medicine capable of realizing high efficiency decolouring, decyanation, and degradation of COD comprises, by weight, 10 to 70 parts of active carbon, 10 to 60 parts of diatomite, 1 to 30 parts of a ferric salt, 1 to 30 parts ofan aluminum ferric salt, and 0.5 to 15 parts of a strong oxidant; the ferric salt is one selected from polymeric ferric sulfate, polymerization ferric chloride, and ferrous sulphate; the aluminum ferric salt is one selected from polyaluminum ferric chloride, polymeric ferric aluminum silicate, and polymeric aluminum ferric sulfate. The advantages are that: excellent flocculation, adsorption, andhigh oxidation functions are achieved; the waste water processing medicine can be used for removing cyanides and COD in waste water at the same time, and is capable of realizing effective decolouring;obtained processed water is low in chroma; efficiency is high; no equipment corrosion is caused; and the preparation method is simple.

Description

Technical field [0001] The invention belongs to the field of wastewater treatment, and in particular relates to a wastewater treatment agent capable of efficiently decolorizing, decyanating and degrading COD. Background technique [0002] Coking wastewater is often difficult to meet discharge standards due to high chroma, high cyanide, and high COD. The chroma, cyanide, and COD in wastewater will deteriorate the water quality of natural water bodies, disrupt water balance, and cause great harm to the water environment. Therefore, it is necessary to decolorize, decyanide, and degrade COD. [0003] Coal chemical coking wastewater has complex components and high concentration of pollutants, especially high levels of toxic organics. Many of the components have carcinogenic effects and are serious to the environment. It has become the most important source of pollution for coking enterprises and must be effectively treated. [0004] Coking wastewater usually adopts A 2 O process treatmen...
