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. The invention overcomes the defects of large consumption and secondary pollution easily caused by using metal hydroxides, metal oxides and metal salts separately as chemical phosphorus removing agents, and simultaneously expands the application fields of the two-dimensional clay.

The present disclosure provides an anisotropic lamellar inorganic fiber aerogel material and a preparation method thereof. The method includes: mixing a polymer solution, an inorganic precursor and a chloride to obtain a spinning precursor solution; blow spinning the spinning precursor solution to obtain a composite fiber aerogel; calcinating the composite fiber aerogel to obtain the anisotropic lamellar inorganic fiber aerogel material. Therefore, the method has advantages of simplicity, easy operation, low cost, high efficiency and easy industrialized production. The inorganic fiber aerogel materials prepared by the above method are composed of multi-layer stacked fibers and have an anisotropic lamellar structure, which can be cut into any desired shape, and stacked to any desired thickness. In addition, the inorganic fiber aerogel materials have good flexibility and compressibility, excellent fire resistance, good high and low temperature resistance and superior thermal insulation, which greatly expands their application field.
