摘　　要：采用室内试验研究了天然沸石对鱼塘水及生活污水氮磷的去除效应,并对沸石茶包净化饲养金鱼水的效果进行了探讨。结果表明,沸石有降低总氮、氨氮、总磷、无机磷的作用,其降低程度随沸石用量的增多而加大,但沸石对含氮磷较高的污水处理效果较差。结果还表明,粉状沸石除氮磷的效果在10d左右较佳,之后效果下降。粉状沸石比块状沸石去除氮磷的效果好,但小块状沸石能维持较长的有效时间。对此应进一步研究。An experiment of removal of nitrogen and phosphorus in fishpond water /sewage by natural zeolite was conducted,and the changes of purifying water used for r aising goldfish with tea -bag pouched zeolite with time were also dealt wi th.It was shown that zeolite possessed effect of lowerin g total nitrogen,ammonia nitrogen,total phosphorus and inorganic phosphorus,and the more amount of zeolite added,the more red uction of nitrogen and phosphorus co ntents in water samples.However,fo r sewage with higher nitrogen and phosphorus,the removal effect became less.It was also show n that ground zeolite had a better eff ect in removing nitrogen and phosphorus within 10days,and th e effect would be less after 10days;c ompared with small blocky zeolite,g round zeolite be-haved better in removing nitrogen an d phosphorus in water used for raisin g goldfish,but a longer effect was fo und with small blocky zeolite,suggesting that a further s tudy was needed.
