A modified zeolite adsorbents and the use of ammonia and regeneration methods

The present invention discloses a modified zeolite adsorbents and the use of ammonia and regeneration process, the preparation of the adsorbent is: natural zeolite after crushing, grinding, acid bubble process, is mixed with an aqueous solution of CuSO4 · 5H2O, high temperature reaction , cooling, cleaning, drying derived products. The method of use and regeneration of the adsorbent is: plexiglass selected adsorption column, the column was added the adsorbent, nitrogen adsorption reaction wastewater adjusted to weak alkaline after PH into the adsorption column by a peristaltic pump. After the adsorption period, the adsorption column backwash complete adsorption, washed with hydrochloric acid or sulfuric acid to the adsorbent, washing liquid recovery and evaporated to give a crystalline ammonium chloride or ammonium sulfate crystals; adsorbent can be reused after cleaning. Ammonia present invention modified zeolite adsorbent capacity, adsorption effect is good, easy regeneration, the adsorbent treatment using a nitrogen-containing waste water, the process is simple, stable effluent.
