To study the influence of external factors on the deactivator effect of a commercial deactivation under field conditions, the effects of different dosage, pH, oscillation time, oscillation frequency and initial phosphorus concentration on the deactivation effect of simulated lake water were studied. The results show that when the other conditions are the same, the deactivator has the best deactivation effect when the dosage is 0.07g, the pH is 6-9, the oscillation time of the deactivator is 45 minutes, the oscillation frequency is medium speed (180r/min), and the initial concentration of phosphorus is not more than 3mg/L. Orthogonal experiments show that the best deactivation effect is that the initial concentration of phosphorus is not more than 3mg/L, the oscillation frequency is medium speed (180r/min), and the dosage is 0.06g. The main effect of SPSS software is analyzed: the influence of initial phosphorus concentration, oscillation frequency and dosage on deactivation effect of the deactivator decreases in turn.
