Abstract

The invention discloses a nano-material water treatment composition, relates to the technical field of water treatment, and solves the problems that an existing nano-material reagent and composition are still difficult to recover, relatively low in efficiency and the like in the water treatment process are solved. The key points of the technical scheme are that the nano-material water treatment composition comprises an adsorption component and an oxidation component, wherein the adsorption component is constructed to be an open storage cavity, and the oxidation component is prepared into particles and then placed in the storage cavity. A unique composition structure is innovatively constructed, adsorption and storage of a product after water treatment are facilitated, diffusion of internaloxidation components is reduced, and the effective utilization rate of a water treatment object is increased; the prepared water treatment composition is combined with the magnetic property of the nano material, so that the adsorption capacity to heavy metals is enhanced, and the probability of secondary pollution is reduced; and the composition has a good treatment effect on heavy metal pollutants and nutrient rich salt at the same time.

Description

technical field [0001] The invention relates to the technical field of water treatment, more specifically, it relates to a nanometer material water treatment composition. Background technique [0002] With the rapid development of my country's manufacturing industry and the substantial improvement of people's living standards, the pollution of natural water bodies caused by excessive development and utilization of water resources, industrial production and domestic sewage has become more and more serious, and the composition of water pollutants has become more and more complex, including many A variety of organic pollutants, heavy metal elements, high-concentration salts, etc. At present, some water treatment agents have been put into use, such as coagulants, coagulants, etc., but relying solely on the addition of these agents can no longer meet the current water treatment requirements, especially for refractory colloids, ammonia nitrogen, and heavy metal ions exceeding the s...
