| Abstract: | In order to solve the problems of low efficiency of flocculation tank in the water treatment plant and high chemicals dosage,the through hole velocity of the flocculation tank was adjusted,and the reasonable velocity gradient was set.After the reconstruction,the efficiency of the flocculation tank is improved.The turbidity of treated water from sedimentation tank is less than 3.0 NTU,the turbidity of filtered water is less than 1.0 NTU,and the chemicals consumption is reduced by 26%. |
