It is found that the blade Angle of the gas dispersion channel, the type of the lower impeller and the impeller spacing have significant influence on the macro-flow field in the tank.

Test results show that the flow regime is good in a head tank with a greater length of the outlet pond and a smaller contract angle, while the sediment deposition is heavy.
试验结果表明，出水池长度较长，收缩角较小的高位井中的水流流态较好，但池内泥沙淤积程度较重。
