Abstract

The invention provides a novel ammonia-nitrogen wastewater treatment material and a preparation method thereof. The material is prepared form components as follows: silica, titanium dioxide, xonotlite, calcium oxide, carbamide, titanium isobutoxide, calcium propanoate, calcium chloride, propyl gallate, ethanol, anhydrous acetic acid and distilled water. The preparation method of the material comprises steps as follows: firstly, mixing carbamide, 50-80 parts of ethanol, distilled water and anhydrous acetic acid to obtain a solution; after mixing titanium isobutoxide, titanium dioxide and the rest ethanol, slowly adding the solution to the mixture while stirring all the time, leaving the mixture to stand, then drying the mixture, grinding the dried substance into powder, sieving the powder, mixing the powder with the rest components, evenly scattering the mixture in a muffle furnace for calcination, and taking out and cooling the product to obtain the material. The novel ammonia-nitrogen wastewater treatment material can effectively remove ammonia nitrogen and COD, is high in adsorbability, has a good removal effect on heavy metal Cd and improves the wastewater quality.

Description

technical field [0001] The invention relates to the field of environmental materials, in particular to a novel ammonia nitrogen wastewater treatment material and a preparation method thereof. Background technique [0002] Water is the source of life, the material basis for the survival of all living things, and the lifeblood of various economic and social activities. However, due to the pollution of water resources in recent years, serious water resource shortages have been caused. According to the survey, the main factors of water pollution are permanganate, ammonia nitrogen, petroleum and heavy metal pollution. Among them, ammonia nitrogen is an important factor leading to eutrophication of water bodies. When sewage containing a large amount of ammonia nitrogen flows into lakes, it will cause algae and microorganisms to multiply and grow wildly, resulting in water hypoxia, water quality deterioration and odor. Heavy metals eventually enter the human body due to their acc...
