Preparation method of water treatment material

Abstract

The invention relates to a preparation method of a water treatment material. The preparation method comprises the following steps: firstly, crushing raw materials, namely kaolin, tourmaline and straw,grinding till 200 meshes, weighing kaolin powder, tourmaline powder and straw powder according to a weight ratio, adding a certain amount of anhydrous ethanol, flour, zinc stearate and cyanoacrylate,and uniformly mixing and stirring; spraying misty water into the uniformly mixed material, then pressing the homogenized mixed material into raw material balls by a pressing machine, and selecting the raw material balls having the particle size of 15-25mm for rounding; firing the rounded raw material balls in a muffle furnace at the firing temperature of 950-1050 DEG C so as to complete preparation of the novel water treatment material. With the kaolin powder as a base material, through addition of the tourmaline powder and the straw, the microporous water treatment material with a large specific surface area, high hardness, high strength and well-developed pores is obtained by a specific processing technology; the sewage treatment effect is good; wastewater can be discharged after the standard is reached.

Description

technical field [0001] The invention relates to the technical field of water treatment materials, in particular to a preparation method of water treatment materials. Background technique [0002] With the rapid development of industry and agriculture and the continuous improvement of people's living standards, the total discharge of industrial wastewater and domestic sewage in my country has been increasing year by year in recent years, but the sewage treatment rate has not been significantly improved, resulting in serious pollution of drinking water sources. [0003] Tourmaline is the general name of tourmaline minerals. After the tourmaline particles are heated, the two ends of the tourmaline particles will have different positive and negative static electricity, so as to attract small objects such as dust. This mineral is called tourmaline because of its pyroelectricity. The chemical composition of tourmaline is complex, and it is a silicate mineral with a ring structure ...
