生物沸石处理含氨废水的研究概述

摘要

Biological zeolite is a new water treatment material,which combines the performance of zeolite selective absorption of ammonia and ammonia removal in biofilm nitrification.It has some advantages,such as high removal rate of ammonia nitrogen,the resist impact load capability and biological regeneration.Zeolite medium biological aerated filter,which used zeolite as the stuffing material,is a kind of effective processor of ammonia containing waste water.There are some influencing factors of running behavior： the particle size of zeolite,hydraulic load,gas water ratio,temperature and pH value.In order to prevent the filter clogging,some zeolite filter bulb were researched and developed to improve the performance of biological zeolite filter.%生物沸石是一种新型水处理材料,它结合了沸石选择性吸氨和生物膜硝化除氨的性能,具有氨氮去除率高、抗冲击负荷和生物再生的优点。采用生物沸石为填料的沸石曝气生物滤池是一种有效的含氨废水处理器,沸石粒径、水力负荷、气水比、温度和pH是影响它运行效果的工况因素。为了防止滤池堵塞,研究开发的一些沸石滤球可以提高生物沸石滤池的性能。
