%X A new type of jet aerator (separate structure jet aerator) was designed and developed, and an idea of separate design was put forth. This type of jet aerator was mainly applied to the treatment of small-scale wastewater and industrial wastewater of high density treatment projects. The experimental set-up was built to investigate the influences of the structural parameters (R1, R2 and R3) on the gas suction flowrate. The experimental results are listed as follows: the gas suction flowrate fluctuates with the changes of R2, and the optimal R2 is relevant to the length of the mixing tube; R3 does not contribute a lot to the suction performance, but choosing a suitable R3 can help to make further use of the gas suction potential of the jet aerator while keeping the other parameters unchanged; R1 has a great impact on the suction performance, and the optimal R1 can be found out in the transitional region. The experiments also prove that it is feasible to apply CFD to designing jet aerator, since its gas suction flowrate is high (reaching 900 approximately 1100 L/min) and it shows prominent performance in agitating liquid.
