沸石在水产养殖业中的应用研究

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。

Study on the Application of Zeolite in Aqaculture

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.
