Abstract

The reuse of solid waste coming from aquaculture and aquaponics industry is good not just in the environment ambit; also is a benefited in the economic aspect because it decreases the organic pollutant charge in the environmental aspect, respect to the economic aspect the fish feces is one of the nutritive dung containing almost 4.47% of nitrogen and 2.35% of phosphorous. So the first step to reusing these nutrients is to get a real measure of nitrogen from aquaculture and aquaponics wastewater after this the next step is to decide which kind of technique will be used to reduce the nutrients to an acceptable level. Aquaponics is a recent technology that has the benefit of joining two technologies: aquaculture and hydroponics. The importance of nitrogen measurement falls into controlling the quantity in aquaponics and aquaculture system to avoid problems related to high concentrations.
鱼类养殖中氮含量测定方法综述
对来自水产养殖业和水培业的固体废物进行再利用不仅在环境方面是有益的;在经济方面也有好处,因为它减少了环境方面的有机污染物负荷,就经济方面而言,鱼粪是含有近4.47%的氮和2.35%的磷的营养粪便之一。因此,再利用这些营养物的第一步是从水产养殖和水培废水中获得真正的氮含量,然后下一步是决定使用哪种技术将营养物减少到可接受的水平。水培技术是一种结合了水产养殖和水培两种技术的新技术。氮测量的重要性在于控制水培和水产养殖系统中的氮量,以避免高浓度的问题。
