The water in the backwater zone enters the cooling tower and then enters the dilutionzone through the water pump.
回 水区的水经水泵进入冷却塔冷却后进入混合区；

MethodsOne is to determine the inhibition zone diameters with filter paper. The other is minimum inhibitory concentration by the double dilution method. ResultsR.
方法采用滤纸片法测定抑菌圈直径，二倍稀释法测定最低抑菌浓度。
