Abstract:
Aquaculture is the major way to solve the global food sacrcity. As the global population increases, the demand for aquaculture increases. Fish feed, drugs and chemicals, and metabolic waste or mortalities of aquatic organisms also increase, eventually resulting in the production of a large amount of aquaculture wastewater. These aquaculture discharges contain a variety of pollutants, such as conventional pollutants, organic compounds, heavy metals, and biological contaminants, inducing occupational hazards and risks, food security, the environment pollution. Proper wastewater treatment technologies are required to remove hazardous pollutants for minimizing their impacts on environmental and human health. Recirculating aquaculture systems, some biological and physicochemical methods have been applied to remove some pollutants from the aquaculture wastewater, but their efficiency in removing pollutants still requires to be further improved for achieving zero-waste discharge and ensuring sustainable aquaculture development. Meanwhile, sound regulation and legislation needs to be established for ensuring the normal operation of aquaculture industries and the standard discharge of wastewater. This review aims to provide comprehensive information of aquaculture wastewater for the researchers and promote the healthy development of aquaculture.
摘要:
水产养殖是解决全球食物圣洁的主要途径。随着全球人口的增加,对水产养殖的需求增加。鱼饲料,药物和化学品,水生生物的代谢废物或死亡率也增加,最终导致生产大量的水产养殖废水。这些水产养殖排放物含有多种污染物,如常规污染物,有机化合物,重金属,和生物污染物,诱发职业危害和风险,粮食安全,环境污染。需要适当的废水处理技术来去除有害污染物,以最大程度地减少其对环境和人类健康的影响。循环水产养殖系统,一些生物和物理化学方法已经被用来去除水产养殖废水中的一些污染物,但是它们在去除污染物方面的效率仍然需要进一步提高,以实现零废物排放和确保水产养殖的可持续发展。同时,需要建立健全的法规和立法,以确保水产养殖业的正常运行和废水的标准排放。本综述旨在为研究者提供水产养殖废水的全面信息,促进水产养殖健康发展。
