The water of similary volume is made to rise to level-one settling zone from two-stage precipitation area, this part ascending current can induce a part of solid particle
Object returns to level-one settling zone, and the angle beta of two-stage precipitation area upper side wall and horizontal plane is more than 90 °, reduces in two-stage precipitation area
Ascending current flow velocity, so as to reduce the probability that solid particulate matter returns to level-one settling zone；
（5）For the water inlet pipe at two-stage precipitation area open top position, the two-stage precipitation area has higher particle
Concentration provides the condition of hindered settling so that a large amount of particulate matters settle in two-stage precipitation area, reduce the particle of level-one settling zone
Object concentration improves whole sedimentation effect；
（6）For the water inlet pipe at two-stage precipitation area open top position, effluent flow rate is very fast in water inlet pipe, into two level
Behind settling zone, since inertia force acts on, particulate matter moves downward, and clear water moves upwards, and can realize the quick of particulate matter and water
Separation.
