But differs in that the flocculation baffle assembly 104 separates the flocculation sedimentation tank one 101, the flocculation sedimentation tank two 102 and the flocculation sedimentation tank three 103 in sequence for water inflow treatment (namely, the flocculation sedimentation tank 100 is divided into four by three flocculation baffle assemblies 104), and the filter screen assembly 105 is arranged in the upper part of the flocculation baffle assembly 104 for filtering out water;
flocculation spacer assembly 104 includes flocculation spacer 1041, spacer aperture 1042, spacer cavity 1043; the partition holes 1042 are provided in the upper portion of the flocculation partition 1041 (mainly for more water storage), the partition cavities 1043 are provided in the inside of the flocculation partition 1041 (mainly for removal of sediment), and the partition holes 1042 and the partition cavities 1043 are communicated (for allowing the filtered sediment to flow from the partition holes 1042 to the partition cavities 1043 while being removed).
However, in order to enhance the sedimentation effect, the partition holes 1042 of the flocculation partition 1041 on the three flocculation partition assemblies 104 are sequentially lowered from left to right (i.e. the height above the ground is lowered one by one), so that, firstly, the water in the first flocculation sedimentation tank 101 reaches the partition holes 1042 and flows into the second flocculation sedimentation tank 102 after being filtered by the filter screen assembly 105, and the water in the second flocculation sedimentation tank 102 reaches the partition holes 1042 and flows into the third flocculation sedimentation tank 103 after being filtered by the filter screen assembly 105, and similarly, the water in the third flocculation sedimentation tank 103 reaches the partition holes 1042 and flows out into the inclined tube sedimentation tank 200 after being filtered by the filter screen assembly 105.
