[0079] Experimental Example 1: Small Test of Polluted Water

[0080] Select raw materials according to the following proportions by weight: 55 parts of clinoptilolite, 10 parts of medical stone, 8 parts of high CEC clay mineral, 25 parts of aluminum sulfate, 20 parts of calcium sulfate, 5 parts of magnesium oxide, and 15 parts of diatomite , 25 parts of modified bentonite, 10 parts of modified volcanic rock, and 10 parts of attapulgite.

[0081] The preparation method of described modified bentonite is as follows:

[0082] (1) Get bentonite and put it into a beaker, add dilute sulfuric acid solution, stir while adding, until stirring evenly;

[0083] (2) After stirring the solution obtained in step (1) for 30 minutes, let it stand for 2 hours;

[0084] (3) place the solution after standing in a low-speed centrifuge and carry out centrifugation under the condition of 5000r / min, and take out the remaining solid;

[0085] (4) washing the solid obtained in step (3) with distill...

Abstract

The invention provides an ammonia nitrogen remover for surface water treatment, and a preparation method thereof. According to the invention, the ammonia nitrogen remover is prepared by mixing clinoptilolite, medical stone, clay minerals, kaolinite, calcium sulfate, aluminum sulfate, magnesium oxide, diatomite, modified bentonite, modified volcanic rock, attapulgite and other natural minerals, canconvert, decompose, flocculate and settle ammonia nitrogen in a surface water body, little affects the pH value of the water body in the reaction process, can form precipitate with ammonium ions, canbe subjected to ion exchange with the ammonia nitrogen in the water body through clinoptilolite, medical stone, clay mineral, kaolinite, diatomite, modified bentonite, modified volcanic rock and attapulgite, and is non-toxic, harmless and high in reaction speed, and in the ammonia nitrogen treatment process of the surface water body, the product is stable and cannot be decomposed into toxic substances, so that the water quality is improved.

Description

technical field [0001] The invention relates to the field of surface water treatment, and more particularly to an ammonia nitrogen remover for surface water treatment and a preparation method. Background technique [0002] Today, with the continuous improvement of people's living standards and rapid economic development, environmental pollution has gradually become the main problem that plagues people's physical and mental health, and water pollution is precisely one of the most important aspects. In recent years, the assessment results of key pollution sources and the monitoring results of surface water It shows that the phenomenon of ammonia nitrogen exceeding the standard in water body indicators is still serious. Recognizing the source of ammonia nitrogen, understanding its hazards, and taking effective treatment measures have become a necessary link to protect the water environment from ammonia nitrogen pollution. [0003] Ammonia nitrogen (referred to as NH3-N), refer...
