Abstract

The invention relates to the technical field of sewage treatment, and aims to provide a novel composite decolorizing agent which comprises a mixture A and a mixture B, wherein the weight ratio of the mixture A to the mixture B is 4: 1; the mixture A is prepared from the following raw materials in parts by weight: 80-100 parts of activated clay and 20-30 parts of corn straw activated carbon; the mixture B is prepared from the following raw materials in parts by weight: 3-5 parts of titanium sulfate, 3-5 parts of ferric chloride, 4-6 parts of ferric oxide, 10-20 parts of aluminum sulfate and 1-3 parts of polyacrylamide. The novel composite decolorizing agent has the advantages that 1, the raw materials of the product have the characteristics of environmental protection, safety, low cost, wide source, high universality and universality, can adapt to decolorization treatment of various different types of wastewater, decolorization treatment is completed in a neutral environment, the pH of the treated effluent is reasonable, the difficulty of subsequent treatment is reduced, the decolorizing agent can be directly added, dilution and dissolution are not needed before use, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a novel composite decolorizing agent and an application method thereof. Background technique [0002] In recent years, with the rapid development of the economy, the discharge of both industrial wastewater and domestic wastewater has increased significantly, and the pressure on wastewater purification and treatment is increasing. The standard discharge of wastewater is directly related to industrial production activities and daily life of the population. orderly unfolding. Wastewater decolorization is a key link in wastewater treatment, and decolorizer is a key reagent used in wastewater decolorization. Decolorizers can be roughly divided into flocculation decolorizers, oxidation decolorizers and adsorption decolorizers according to their decolorization principles. Flocculation and decolorization agent is a quaternary ammonium cationic polymer compound with multiple fun...
