1. The structure of ordinary rapid filter tank:
There are dr*nage troughs, filter material layers, padding layers and water distribution systems in the rapid filter tank; there is a centralized pipe gallery outside the tank, equipped with pipes and accessories such as water inlet pipes, water outlet pipes, flushing water pipes, and flushing water discharge pipes.
During filtration, muddy water with coagulant added enters the filter tank from the water inlet pipe through the water collection channel and dr*nage trough, passes through the filter material layer and padding layer from top to bottom, is collected by the water distribution system, and is discharged through the outlet pipe. At this time, F1 and F2 are turned on, and F3, F4, and F5 are turned off. After a period of filtration, the amount of suspended matter intercepted by the filter material layer increases, the porosity of the filter layer decreases, and the pore water flow rate increases. As a result, on the one hand, the filtration resistance increases, and on the other hand, the water flow increases the scouring force of the impurities intercepted in the pores, which makes the effluent water quality worse. When the head loss exceeds the allowable value, or the suspended matter concentration of the effluent exceeds the specified value, the filtration should be terminated and the filter tank should be backwashed. During backwashing, F3 and F4 are turned on, and F1 and F2 are turned off. The backwash water enters the filter tank through the flushing water pipe and the water distribution system, passes through the padding layer and the filter material layer from bottom to top, and finally is discharged from the dr*nage trough through the water collection channel. After the backwash is completed, it enters the next filtration cycle.
