Abstract
The invention discloses a preparation method of a material for adsorption removal of organic matter and ammonia nitrogen. The preparation method comprises the following steps that (1) clinoptilolite is selected from natural zeolite, cleaned and elutriated through distilled water for three times; (2) stirring is conducted for 30 min in a high-speed stirring machine, and then precipitation is conducted; (3) upper turbid liquid is removed through a sieve net of 100 meshes; (4) the cleaned clinoptilolite is dried for 24 h in a drying oven at 100 DEG C; (5) a material A is prepared; (6) a materialB is prepared; (7) a material C is prepared; (8) a material D is prepared; (9) a material E is prepared; (10) a material F is prepared; (11) a material G is prepared; (12) a material H is prepared; (13) a material I is prepared; (14) a material J is prepared; and (15) a final adsorption material K is prepared. The natural zeolite and coal ash which are low in cost and easy to obtain are taken as basic raw materials, the natural zeolite is modified by NaCl and then mixed with a 4A molecular sieve prepared from the coal ash according to a certain ratio, thus the novel adsorption material is obtained, and the material has a great organic matter and ammonia nitrogen adsorption effect.
