Abstract
Description
technical field
[0001] The invention relates to a material preparation technology for fixing phosphorus in natural water bodies and lake bottom sediments, and a technology for fixing phosphorus in fresh water blooms, lake bottom sediments and river courses. Specifically, it uses chloride salts, nitrates, or a mixed solution of the two rare earth elements (such as lanthanum, zirconium, etc.) to modify the clay to obtain a high-efficiency phosphorus-fixing material, and use it to fix fresh water Hua, lake bottom sediments and phosphorus technology in river courses. The invention belongs to the technical field of water treatment. Background technique
[0002] The outbreak of harmful algae in natural lakes and rivers (commonly known as red tide in seawater and algae bloom in freshwater) has become a global environmental pollution problem. Facts have proved that phosphorus is a key factor in controlling water eutrophication, and controlling phosphorus is more effective in contr...
