Abstract
Under the condition of ensuring the hydraulic retention time of wastewater,in order to study the influence of the structure of up-flow multiphase wastewater treatment oxidation tower(UHOFe)and the influent parameters and stirring speed on the uniformity of the inter-nal flow regime in the reactor,the influence of loaded stirring blades on the internal flow field in the UHOFe reactor was investigated by the numerical simulation method of computational fluid dynamics(CFD).Firstly,the parametric model of the reactor was established,and the in-plane velocity variation coefficient(MF)was introduced as the evaluation index of the inflow uniformity.Then,using the computer fluid dynamics software ANSYS 2022,combined with single factor and orthogonal experiments,the three-dimensional flow field numerical simula-tion for the flow state of internal fluid in the reactor was carried out.The simulation results showed that loaded stirring blades could strength-en the mixing of liquid in the reactor,and when the outlet height was 12 850 mm,the inlet velocity was 3 m/s,the stirring blade size was 1 300 mm,and the stirring speed was 140 r/min,the effect of water inflow uniformity in the reactor was the best,which was the most condu-cive to improving the mixing efficiency of Fenton system agents and ultimately improving the efficiency of sewage treatment.关键词
