Taking the simulated beneficiation wastewater as the research object, different flocculants and coagulant aids were screened and combined, and the experimental parameters were optimized to make the treated beneficiation wastewater meet the requirements of beneficiation water quality. The experimental factors to be explored include the type of coagulant, the type of coagulant aid, the dosage of calcium chloride, pH value, stirring speed, stirring time, standing time, etc. The data set contains a total of 591 data.
Indoor experiment, self generated.
Place the prepared 1L beneficiation wastewater on the six unit mixer, add different kinds and doses of coagulants and coagulant aids, mix quickly at 160 R / min for 3 minutes, slowly at 60 R / min for 5 minutes, and settle for 30 minutes. Then take the supernatant, measure its turbidity and calculate the removal rate, screen out the best coagulant and coagulant aids and the best dosage, and further optimize the influencing factors such as coagulation mixing intensity, coagulation mixing time and static settlement time, Determine the best experimental parameters of coagulation treatment of tungsten mine refractory wastewater
The suspended matter concentration of simulated beneficiation wastewater is determined according to the standard of GB 11901 water quality - Determination of suspended matter - Gravimetric method (detection limit: 5 mg / L), and the turbidity is determined by the scattered light turbidimeter calibrated with formalin turbidity standard solution.
<p> Good data quality.
