摘　　要：分析了高原地区大气压的变化,随着海拔高度的增加,大气压越来越小,空气含氧量越来越少,但处理焦化废水的实际需氧量不变,所以要求增加供气量。在选择鼓风机时要比平原地区大。The change of atmospheric pressure in tableland area is analyzed. With the increase of the height above sea level, the atmospheric pressure becomes lower and lower, the oxygen content in air be- comes less and less, but the actual oxygen demand for treating coking waste water is not changed, therefore the increase of air supply is required. When blower is selected, the capacity of blower should be higher than that of the blower used in plain area.

关 键 词：大气压 含氧量 供气量
