工厂锅炉排出的炉渣,常被视为废物,不仅占用田地,而且污染环境。现在世界上它已被广泛用于工农业生产的各个领域,今就农业上的用途介绍如下: 1 炉渣养虾我国台湾省用炉渣垫铺在鱼池底部,然后养对虾,成活率达84％,并能长到上市规格。而未铺炉渣的幼虾成活率仅50％～60％。这是因为炉渣中含有一定比例的碱性物质。而对虾在水中排泄的粪便酸性强,因此,将炉渣铺垫在鱼池底部,能有效地中和水中酸性,改善对虾生活环境。
Slags from factory boilers are often considered as waste, not only occupying the fields, but also polluting the environment. Nowadays it has been widely used in all fields of industrial and agricultural production in the world. Nowadays the agricultural uses are described as follows: 1 Slag shrimp breeding In Taiwan, China, the slag pad is laid at the bottom of fish ponds and then prawns are raised. The survival rate is 84% And can grow to market specifications. The unsalted shrimp juvenile survival rate of only 50% to 60%. This is because the slag contains a certain percentage of alkaline substances. However, excrement excreted by shrimp in the water is very acidic. Therefore, laying the slag at the bottom of the pond can effectively neutralize the acidity in water and improve the living environment of shrimp.
