Abstract

PURPOSE: To enhance treatment efficiency and reduce the amount of excess sludge formation by subjecting the organic-contained waste water such as waste water of brewing etc. to bacteria treatment in the absence of protozoa to oxidation-decompose the organic substances and convert them to non-cohesive bacteria then subjecting the waste water to adhesive protozoa treatment, etc. in the absence of non-adhesive protozoa.
CONSTITUTION: The treating waste water 7 containing organic substances enters the first treating tank 1, where it is contacted with the air from an aerating pipe 5. Here, the organic substances are oxidation-decomposed by bacteria and are converted to non-cohesive bacteria. Next, the waste water 8 which does not contain sludge and contains dispersed bacteria enters the second stage treating tank, where it is contacted with the air from an aerating pipe 6 in the presence of the sludge composed of the adhesive protozoa aggregates returned from a precipitating tank 3. Here, the bacteria in the waste water are converted to the adhesive protozoa, whereby sludge is formed. The treated waste water 9 is admitted into the precipitating tank 3, where the sludge components are sedimented and separated and are then returned to the tank 2 via line 11. Part thereof are extracted as excess sludge and the waste water 10 is discharged.
