Title: Waste water treatment apparatus
Inventor: MIURA MITSUGI
IPC: C02F3/12
Filed: 1978-06-21
Abstract: PURPOSE: To increase loading capacity of active sludge and BOD concentration in a waste water treatment apparatus, an ejector is provided to the bottom of treating bath and an equipment is installed to aspirate air by use of circulating water containing sawdust.  
     CONSTITUTION: The treating bath 1 is filled with porous material such as lignin- removed sawdust, chaff, etc. The pump 3 sends raw water from supply pipe 4 and circulating liquid from the cylindrical container 2, which advances through an ejector 5 to the uprising tube 7 in the treating bath 1, while sucking air bubble through the valve 6. The uprizing flow changes its direction downward by the barrier plate 8. The flow goes to the container 2 from which part of the flow advances to the precipitating separator 11, where active sludge sedimentates to be removed from the valve 13, and supernatant water goes out from the outlet tube 12. In this process, a large quantity of medium used effectively deposits a great amount of active sludge. Thus, treatment speed is increased, resulting in BOD loading capacity 5 times as great as conventional process. Further, the process is free from bulking phenomenon, eliminating the use of air inlet fan to reduce installation cast.
