摘要： PURPOSE:To perform the removal of the turbidity component from treated water at low cost, by allowing the biomembrane formed on the contact material in a catching aparatus to catch the turbidity component propagated in the treated water of a bioreactor. CONSTITUTION:The waste water to be treated flowing in a bioreactor tank 1 from a raw water introducing pipe 2 flows up and down by air injected upwardly from an air diffusion pipe 5 to be contacted with an immobilized bacteria carrier 4 moving in a suspended state to undergo aerobic biological decomposition and the org. substance in waste water is decomposed and removed. Treated water containing a turbidity component flowing in the rising passage 16 of a catching tank 14 is held to an aerobic atmosphere by air injected upwardly from an air blow-out pipe 17 and the treated water in the rising passage 5 rises and flows by lift action due to the injection of air to suck treated water in the bottom part side of the catching tank 14. By this method, treated water comes to a recirculation stream to be caught by a contact material.

摘要： 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.
