Abstract

PURPOSE: To enhance the purifying power of a waste water treating vessel while lowering an amount of generated sludge, by arranging an aerating part, comprising a packed layer and an aerating pipe, located at the lower portion of a purifying vessel, and a filtering part, comprising an upper filtering layer and a lower filtering layer provided with a pipe for purified water, located at the lower portion of the purifying vessel.
CONSTITUTION: Untreated water is supplied through an untreated water pipe 8, while the water is aerated with air from an aerating pipe 7 by opening a solenoid valve 25. Another solenoid valve 18 is then opened to collect purified water through a purified water pipe 14. At an aerating part 2, bubbles float upwards through an aerating chamber 6 together with in-vessel liquid to feed oxygen to the latter. The rising in-vessel liquid is mixed with the untreated water through the untreated water pipe 8 and let flow downwards through a packing layer 4. Thus, the liquid repeatedly comes in contact with biomembranes on the packing, and BOD components in the waste water are decomposed and removed. If bacteria do not exist in the packing layer 4 at the beginning of operation, bacteria in the waste water and those introduced from the air adhere onto the packing, proliferate and form the biomembranes.
