Abstract

PURPOSE: To maintain the concentration of phosphorus in treated water constant, by providing an anaerobic tank, an aeration tank for aerobic treatment, a biological dephosphorizer having a means for the solid-liquid separation of an aerated liquid and then a tank for a phosphorus adsorbent.
CONSTITUTION: Raw water 5 and returned sludge 6 in state mixed with each other are introduced into an anaerobic tank 1 and gently agitated therein under a condition isolated from air to perform anaerobic treatment. An aeration tank 2 is constituted in a manner such that aerobic treatment can be performed by supplying air through a sparger pipe 7, and a solid-liquid separation tank 3 is constituted in a manner such that an aerated liquid can be separated into a liquid and solid matter by precipitation. The interior of a tank 4 for a phosphorus adsorbent is packed with a phosphorus adsorbent, e.g. activated alumina, a magnesia compound, a phosphate mineral or ion-exchange resin, to form the bed of the phosphorus adsorbent. A liquid having flowed out of the solid-liquid separation tank 3 is brought into contact with the fluidized or stationary bed to adsorb or discharge phosphorus in said liquid. Thus, the concentration of phosphorus is adjusted to a constant level.
