Problems solved by technology

The main disadvantage of this type of decolorizing agent is that the unit price is very high, generally more than 10,000 yuan, and the quality is more than 30,000 yuan. Even the inorganic decolorizing agent currently used in the market-activated carbon has a price of 10,000-20,000 yuan. Yuan / ton or so
When treating high-chroma wastewater, the amount added will be relatively large, so that the treatment cost will remain high

Abstract

The invention discloses a mineral decolorant and a preparation method thereof. The mineral decolorant is aluminosilicate. The preparation method of the mineral decolorant comprises the steps of (S1) crushing a mineral product into 180-200-mesh mineral powder, adding the mineral powder to water at the solid-to-liquid ratio of 1:(7-13) and stirring at a speed of 100-140r/min for 0.5-1.5h to obtain a mineral powder solution; (S2) adding a dispersing agent to the mineral powder solution and stirring, wherein the mass ratio of the dispersing agent to the mineral powder solution is (1-5):10,000; (S3) screening out selected mineral powder; (S4) adding the selected mineral powder into a 0.8-4mol/L acid liquid at the solid-to-liquid ratio of 1:(2-5) and carrying out activating treatment under the condition of 60-90 DEG C for 1-8h to obtain an activator; (S5) washing the activator with clean water until the pH value is 3-5; and (S6) drying the washed activator at 90-110 DEG C to obtain the mineral decolorant. Compared with an existing decolorant, the mineral decolorant is lower in cost, and higher in cost performance when achieving the same decoloring effect.

Description

technical field [0001] The invention relates to the technical field of decolorizing agent preparation, in particular to a mineral decolorizing agent and a preparation method thereof. Background technique [0002] Decolorizers can be roughly divided into three categories according to the principle of decolorization, flocculation decolorizers, oxidation decolorizers and adsorption decolorizers. Flocculation and decolorization agent is a quaternary ammonium cationic polymer compound that integrates multiple functions such as decolorization, flocculation, and COD degradation. Adsorption and decolorization agents are generally activated carbon, white clay or adsorption resin, which can directly filter out impurities and oxides in oil products by filtration, integrating impurity removal, deodorization, decolorization and separation. Oxidative decolorizing agent uses oxidizing substances, such as sodium hypochlorite, potassium permanganate, ozone, etc., to destroy the colored grou...
