摘要
Abstract
In order to improve the adsorption ability of synthetic zeolite,his paper respectively uses HCl,NaOH,KC1 to modify zeolite.The results show that zeolite modified by the 5％ potassium ehlorid e have better adsorption rate of ammonia nitrogen than others.This experiment studied the influence of the reaction time,the dosa ge of zeolite,the pH value,the concentration of ammonia nitrogen wastewater and the temperature on adsorption rate of ammon a nitrogen.The experiment shows that when the dosage of modified zeolite is 3.0g,the pH value of ammonia wastewater is bet ween 4.0 and 7.0,the mixing time is 80min,the adsorption rate of ammonia nitrogen on 100mL ammonia nitrogen wastewater who se mass concentration is 77.5mg/L is better,which can meet the secondary standard of"Integrated Wastewater Discharge Standard" GB8978-1996).关键词
