비석시일충천연、유효、개렴적배경우호형재료,기대안담구유흔강적선택흡부성。본문취국내재비석거제수중안담적궤리、영향인소、비석적개성급비석연구적발전등방면진행엄범탐토。천술료국내비석거제수중안담적응용현상화진전,병지출비석적추엄요의뢰우비석개성화여기타공예적련용기술개발。
Zeolite is a natural,effective and cheap material to absorb ammonia nitrogen specially.In this paper,the respects including mechanism of removing ammonium from water by zeolite,influencing factors,the modification of natural zeolite and the researches related were discussed widely.The status quo of applications of zeolite to remove ammonia nitrogen in China was introduced.It pointed out that extension application of zeolite depended on the modification of zeolite and the combination of zeolite with other processes.
