In surface water bodies, ammonium nitrogen is a widespread and essential substance for living organisms, and it is also a common substance in polluted source water, and excessive ammonium nitrogen will lead to eutrophication of water bodies. This paper summarizes and analyzes the modification and regeneration methods of zeolite in current water treatment and the current research status of modified zeolite for removing ammonium nitrogen in water, and tests a variety of modifiers for zeolite modification by immersion, and the test found that CTAB (cetyltrimethylammonium bromide) as a modifier has a counteracting effect on the adsorption of ammonium nitrogen by zeolite, and SDBS (sodium dodecylbenzenesulphonate) as a modifier modifying zeolite has a very good Under the condition of pH 7, the removal rate of zeolite modified by 20 g/L SDBS solution for 50 mL of a 5.0 mg/L ammonium solution could reach 72%, and the regeneration of adsorption-saturated zeolite with 1 mol/L NaOH + NaCl solution still reached 86.3% regeneration rate after three times of desorption and regeneration.
