Abstract
PURPOSE: To regenerate disposed water at low cost and stably by detecting the backwash period of a sand filter tank by using a reserve adsorption tank while obtaining excellent disposed water by utilizing an upper current type sand filter tank with a deairing pipe and a coarse inwall.
CONSTITUTION: Waste water passes through a rapid coagulation tank 3 and a slow coagulation tank 4 from a storage tank 1, and formed flock deposits at a sedimentation tank 5 and separated from supernatant liquid. Overflown water is sent to a reserve adsorption tank 12 encasing a filter medium 13 for adsorbing residual suspended matters. The hole diameter, the number of stages, etc. of the filter medium are selected so that hydraulic pressure in the tank 12 reach 0.35 kg/cm2 when the efficiency of filtration lowers due to the fouling of a sand filter tank 14, and a pressure transmitter Px informs the backwash time of the tank 14. Disposed water is injected to a lower portion of the upper current sand filter tank 14. The inwall is shaped in a surface, such as, a coarse surface, which has a large number of unevenness with approx. 2W3 mm difference, thus allowing the prevention of the flowing of a large quantity of disposed water along a smooth side-wall.
