Abstract:
The effects of water hyacinth on purification of different concentrations of fluoride concentration in water and the effects of the plant itself were studied by using the control method of water hyacinth as the test material,so as to provide the theoretical basis for purifying fluoride in water.The results showed that the water hyacinth had a good effect on the fluoride removal under different concentrations of fluoride stress.After 8 days,the removal rate was 25 88%-52 59%.The correlation coefficients of fluoride content in water were more than 0 95,and the difference between C0 and initial concentration was small.The activity of SOD and POD in the enzyme activity increased,and all of them increased and then decreased.In the synergistic external conditions,the corresponding protective plant system was made,and the contribution of POD was relatively large,CAT had no obvious change.
