Embodiment Construction
[0036] This embodiment is a method for controlling the release of nitrogen and phosphorus in the polluted bottom mud, covering the bottom mud with aluminum-zirconium modified zeolite in situ.
[0037] In this example, the aluminum-zirconium modified zeolite includes 10 parts by weight of natural zeolite with a particle size of 0.5-1 mm, 3 parts of anhydrous aluminum trichloride, 1 part of zirconium oxychloride octahydrate, and 50 parts of distilled water.
[0038] The preparation method steps of in-situ covering material 2 in this example are as follows:
[0039] a. According to the above parts by weight, after rinsing the natural zeolite for 2 to 3 times to remove impurities, place it in an oven at 105°C for drying;
[0040] b. According to the above parts by weight, anhydrous aluminum trichloride, zirconium oxychloride octahydrate and distilled water are mixed, stirred and dissolved according to the proportioning ratio to form a mixed solution;
[0041] c. Add the natural z...
