\nA certain concentration of simulated water sample was prepared with diatomite and anti-corrosion emulsified oil. The treatment effects of PFS, P (am-dmdaac-odma) and composite flocculant on turbidity and oil content of simulated water sample were tested. The effects of flocculant dosage, temperature and pH on the treatment effect of simulated water sample were investigated respectively. In addition, the mine water from a coal mine in Yulin City, Shaanxi Province was taken to test the actual treatment effect of PFS, P (am-dmdaac-odma) and composite flocculant on mine water. The data set contains 296 data and 4 groups of data.

Transfer the upper extract to a conical flask that has been added with 3G anhydrous sodium sulfate, close the cork, shake several times and stand still. Repeat the above steps to extract the lower aqueous phase in the beaker again to ensure that the oil in the aqueous phase is fully extracted.
