(3) In the second stage of precipitation, the first precipitation tank 5 is kept stand, and the second precipitation tank 6 is filled with water.
(4) In the third stage of precipitation, the first sedimentation tank 5 is discharged, and the second sedimentation tank 6 is continuously fed with water. When the water level of the second sedimentation tank 6 reaches the designed predetermined water level after a period of time, the floating ball 16 in the second sedimentation tank 6 lifts up to open the first composite valve 20 of the water outlet valve 19 of the first sedimentation tank 5, as in step (1), the second composite valve 21 in the first sedimentation tank 5 is in an open state, and when the first composite valve 20 is opened, the water outlet valve 19 of the first sedimentation tank 5 is opened, and water flows to the filter tank 7. The predetermined water level is usually designed according to the water inlet speed, and is typically half to two thirds of the highest water level, and the water level reserved by the second sedimentation tank 6 is used for continuing water inlet before the first sedimentation tank 5 finishes water outlet.
(5) And in the fourth stage of precipitation, the first sedimentation tank 5 is filled with water, and the second sedimentation tank 6 is kept stand for precipitation. When the water level of the first sedimentation tank 5 drops to a designed low value, the floating ball 16 in the floating ball valve 17 in the first sedimentation tank 5 descends to open the floating ball barrel water outlet 153, the floating ball 16 in the floating ball barrel 15 descends, the first water outlet 112 of the water inlet valve 11 is opened, and the second water outlet 113 is closed, at this time, since the floating ball valve 17 opens the water outlet of the floating ball barrel 15, and the water level of the first sedimentation tank 5 is at a low value, the water outflow of the floating ball barrel 15 of the second composite valve 21 is controlled, the second composite valve 21 is closed, the water outlet valve 19 is closed, the first sedimentation tank 5 starts to feed water, and when the water level continues to rise, the floating ball valve 17 closes the floating ball barrel water outlet 153, and the water level in the floating ball barrel 15 cannot continue to rise, thereby keeping the water outlet valve 19 closed.
(6) In the fifth stage of precipitation, the first sedimentation tank 5 is filled with water, and the second sedimentation tank 6 is discharged with water. When the water level of the first sedimentation tank 5 rises to a designed certain water level, for example, 2/3, the floating ball 16 (arranged in the first sedimentation tank 5) of the first compound valve 20 of the water outlet valve 19 of the second sedimentation tank 6 rises to open the first compound valve 20, since the water level of the second sedimentation tank 6 is at a high position, the second compound valve 21 of the second sedimentation tank 6 is in an open state, the water outlet valve 19 of the second sedimentation tank 6 is opened, the water outlet of the second sedimentation tank 6 starts to discharge water, after the water level of the second sedimentation tank 6 is reduced to a low value, the second compound valve 21 of the second sedimentation tank 6 is closed, the first sedimentation tank 5 continues to feed water to a preset water level, and water enters from the floating ball cylinder water inlet 152 of the first sedimentation tank 5, thereby closing the first water outlet 112 of the water inlet valve 11 and opening the second water outlet 113.
(7) The above-mentioned processes are circulated, so that the alternate precipitation of two precipitation tanks can be implemented.
The present invention is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present invention.
