1概述鱼池与池水的循环处理系统有机组合,便构成了工厂化养鱼的主体,其水处理系统相当于一个小型的微污染水的处理工厂,且不断处理、回用、再循环。据有关资料报道,一般污水处理厂总电耗中,曝气设备的电耗约占60%-70%,我国养鱼工厂曝气(增氧)设备的电耗占总电耗的比例尚未见报道。与一般污水处理厂相比,养鱼工厂污水由于浓度低,耗氧量相应少,但是鱼的耗氧量很大。不同品种的鱼,耗
1 Overview The organic combination of fish pond and pond water recycling system constitutes the mainstay of factory fish farming. Its water treatment system is equivalent to a small micro-polluted water treatment plant, which is continuously treated, recycled and recycled. According to relevant information, the total electricity consumption of general sewage treatment plants, the electricity consumption of aeration equipment accounts for about 60% -70%, China’s fish farming aeration (aerobic) equipment, the proportion of the total power consumption has not yet seen Reported. Compared with the general sewage treatment plant, fish factory sewage due to low concentrations, corresponding to less oxygen consumption, but fish consumption of oxygen is very large. Different varieties of fish, consumption
