Abstract

The invention relates to the field of wastewater treatment, in particular to a material for synchronously removing ammonia nitrogen and phosphorus and a preparation method thereof. The material comprises the following raw materials in parts by weight: 6-10 parts of kaolin, 1-4 parts of bentonite, 10-20 parts of sodium carbonate, 60-100 parts of water, 3-8 parts of zirconium oxychloride and 5-9 parts of lanthanum cerium chloride, wherein the mass ratio of zirconium oxychloride to lanthanum cerium chloride is 5: 7, and the mass ratio of sodium carbonate to zirconium oxychloride is 3: 1. According to the invention, amorphous oxides of zirconium, lanthanum and cerium are formed through zirconium oxychloride and lanthanum cerium chloride under the action of sodium carbonate; and the invention further provides a preparation method of the material for synchronously removing ammonia nitrogen and phosphorus, and the preparation method is simple in preparation process, mild in condition and suitable for industrial application.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a material for synchronously removing ammonia nitrogen and phosphorus and a preparation method thereof. Background technique [0002] Ammonia nitrogen refers to the free ammonia (NH 3 ) and ammonium ions (NH 4 + ) in the form of nitrogen. An appropriate amount of nitrogen in water is a basic element for the synthesis of algae and other microorganisms, an important material condition for the formation of an aquatic ecological environment, and the basis for a virtuous cycle of the water environment. However, at present, the total amount of nitrogen in some water bodies has exceeded the capacity of the water body. Excessive nitrogen elements lead to abnormal proliferation of algae and other organisms in the water body, causing water quality to deteriorate. In addition, the pollution of ammonia nitrogen also poses a threat to the safety of drinking water, harms fish and other ...
