Research on the Effect of Flocculation Precipitation Filtration Technology in Treating Continuous Casting Turbid Circulating Water in Steelmaking Plant
In order to further optimize the continuous casting turbid circulating water treatment process in a steel plant,combined with the actual situation of a certain steel plant,a combined treatment mode of flocculation precipitation and filtration was adopted.Through single factor experiments,the technical parameters of the sedimentation and filtration processes were adjusted.Finally,the reasonable parameters for this treatment plan were determined as follows:the flocculant was added to a mixture of 4 mg/L PAC,0.1 mol/L pure alkali solution,and 0.1％hydrated lime solution,activated zeolite was used as the filter material for filtration,and the filtration rate was 7 m/h.The actual application results show that the effluent effect of the optimized scheme is significantly better than the initial scheme,and this scheme has certain application value.
