摘要
本试验观测了沸石在不同粒径、不同用量、不同食盐水体中的除氨效果,并用沸石进行了防治鱼类氨中毒、泛池和改良水质试验。结果表明:沸石粒径越小,陈氨量越大。在试验浓度范围内,沸石用量越大,除氨率越高;水中含盐量越高,除氨率越低。沸石对防治鱼类氨中毒、泛池及改良水质均有显著作用。
The ellects ol ammonia removalby zcolite with different size, different dosageand in different salinity water were studied.The experiment that prevent the toxicosis ofammonia, avoid the absent oxygen. and im-prove adverse water by zeolite was carried outThe results showed that the smaller size ofzeolite, the more effective of ammonia re-moval. The results also showed: In the variedconcentration in the experiment, the moredosage of zeolite. the more effective of ammo-nia removal; the higher salinity of the water,the lower proportion of the ammonia removal.Zeolite has marked effect in preventing fishtoxicosis of ammonia, keeping away from ab-sent oxygen; al1d improving adverse water.
