Problems solved by technology

The solubility of ozone in water is small and it is easy to spontaneously decompose into oxygen that is ineffective for the oxidation and degradation of wastewater treatment, and the concentration of negative oxygen ions in water is usually very small. Solubility and catalytic activation of ozone decomposes into hydroxyl radicals with stronger oxidative degradation ability

Abstract

The invention relates to a nano ion composite for wastewater treatment. The composite comprises the following raw materials by mass percentage: 40-50wt% of anion powder, 40-50wt% of an ozone activating catalyst, 5-8wt% of a solid slow release demulsifying agent and 5-10wt% of gel. The preparation method of the composite comprises the following steps of weighing the raw materials according to the corresponding mass percentage, mixing and sufficiently grinding the anion powder, the ozone activating catalyst and the solid slow release demulsifying agent, adding the gel of the corresponding mass to the ground powder, stirring and mixing, and finally performing pelleting in a pelleting machine. The nano ion composite has the benefits that the nano ion composite can effectively improve solubility of ozone and negative oxygen ions in water, and activate and decompose partial ozone into a hydroxyl radical with better oxidative degradation capability, and the oxidative degradation treatment efficiency of organic pollutants such as oil in wastewater is improved.

Description

technical field [0001] The invention belongs to the field of waste water treatment, and in particular relates to a nano ion composite material used for waste water treatment and a preparation method thereof. Background technique [0002] Today, the speed of sewage treatment cannot keep up with the speed of water pollution, the artificial treatment of water cannot catch up with the speed of water pollution, the understanding of viruses cannot keep up with the speed of virus mutation, the degradation of organic matter cannot keep up with the speed of organic compound synthesis, and the restoration of the earth's ecology cannot keep up with the destruction of modern economic development. Domestic wastewater has high oil content, high suspended solids, high cod, high ammonia nitrogen, and high heavy metals, which have seriously affected the living environment of surrounding people, animals and plants. If the domestic wastewater as the source of pollution cannot be properly treat...
