  • Patent number: 11053128
    Abstract: The present invention belongs to the field of material preparation, and particularly relates to a two-dimensional clay based composite phosphorus removing agent and a preparation method. The two-dimensional clay based composite phosphorus removing agent provided by the present invention takes two-dimensional clay, hydroxide (such as lanthanum hydroxide, calcium hydroxide, magnesium hydroxide and aluminum hydroxide) and urea as raw materials, and the composite phosphorus removing agent with high property is prepared by a roasting method. Through a combined physical and chemical method, phosphorus in the phosphorus-containing wastewater is effectively removed by the synergic interaction between components of the composite phosphorus removing agent.
