Example Embodiment

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further explained below in conjunction with specific embodiments.

[0028] Such as figure 1 As shown, this embodiment provides a method for preparing a material for adsorbing and removing organic matter and ammonia nitrogen, including the following steps:

[0029] 1) Clinoptilolite is selected from natural zeolite and washed, and washed with distilled water three times;

[0030] 2) Stir in a high-speed mixer for 30 minutes, then settle;

[0031] 3) Use a 100 mesh screen to remove the turbid liquid on the upper part;

[0032] 4) Dry the cleaned zeolite in an oven at 100°C for 24 hours;

[0033] 5) Put the dried zeolite into a muffle furnace for pre-activation, burn it at 450°C for 60 minutes, and cool it down to room temperature to obtain material A, and put it into a sealed bag for later use;

[0034] 6) Prepare 5mol / L ...

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.

Description

technical field [0001] The invention relates to a preparation method and application of a material for adsorbing and removing organic matter and ammonia nitrogen, and belongs to the technical field of sewage treatment. Background technique [0002] Water is a basic natural resource and a strategic economic resource. It occupies an important position in the national economy. High-quality clean water is the basis for human survival and development. Although my country has a large amount of water resources, the per capita water resources are equivalent to a quarter of the world's average level, and the water resources are seriously polluted, which puts forward urgent requirements for the control of water pollution and the improvement of water quality in our country. Therefore, how to reduce the concentration of ammonia nitrogen in non-drinking water sources in nature to the third type of surface water environmental standard, which is less than 1mg / l, is a current research hotsp...
