<p>PROBLEM TO BE SOLVED: To provide a technique for cleaning industrial wastewater discharged in great volume, particularly factory wastewater discharged from a chemical factory, where phenolic resins and their derivatives are manufactured, or a food factory, where isomeric sugars and derivatives of starch are manufactured, by using a carbon fiber floating in a wastewater treating tank and activated sludge and microbes adhered or deposited on an activated carbon fiber, which is resulted from studying various measures for solving the problem that it is extremely difficult to satisfy the conditions to always adjust the ecological system of microbes in the wastewater treating tank and the problem to dispose waste sludge and to provide a technique for reducing waste sludge. SOLUTION: This technique consists of a method for cleaning factory wastewater by using the carbon fiber floating in the wastewater treating tank and activated sludge and microbes adhered or deposited on the activated carbon fiber. The ecological system of microbes in the wastewater treating tank is stabilized by developing biological activity by carbon, particularly enhancing the affinity of carbon for organisms. As a result, waste sludge can be reduced and the conditions to always adjust the ecological system of microbes can be easily satisfied in the wastewater treating tank.</p> |
