1 根据水域情况,选购增氧机 目前全国增氧机大致有9个系列,36个品种,可根据水域大小,经济状况,电源等因素购置增氧机械。一台三千瓦的增氧机,负荷水面5～7亩,最多不超过10亩。2 增氧时间要科学 夏秋季高温季节应特别注意开动时间。晴天,开机时间多在中午,因为中午水层表面温度相差很大,通过增氧,促进上下水体对流,保持水体温度平
1 According to the water situation, buy aerator Currently there are roughly 9 series of aerator, 36 species, according to the size of the waters, economic conditions, power and other factors purchase oxygen machinery. A three kilowatt aerator, the load surface of 5 to 7 acres, up to not more than 10 acres. 2 aerobic time scientific summer and autumn hot season should pay special attention to start time. Sunny days, boot time and more at noon, because the water surface temperature at noon vary greatly, through oxygen, to promote the upper and lower body of water convection, keep the water temperature level
