<p><P>PROBLEM TO BE SOLVED: To provide a waste water treatment system capable of treating waste water in a short period of time. <P>SOLUTION: The waste water treatment system comprises a pretreatment process 100, a biological treatment process 101, a microorganism culture process 102, a filter treatment process 103, a membrane treatment process 104, and an inspection process 105. In the biological treatment process 101, mixed liquid containing 10<SP>7</SP>to 10<SP>10</SP>pieces of microorganisms per milliliter and a nutrient source for accelerating the propagation of microorganisms are supplied to a first aeration tank together with waste water, and the microorganisms decompose an organic matter in the waste water while forming biological slime on the surface of activated carbon. In the microorganism culture process 102, the spawn of the microorganisms and the nutrient source for accelerating the propagation of the microorganisms are supplied to a second aeration tank together with the waste water, and the microorganisms are propagated to 10<SP>7</SP>to 10<SP>10</SP>pieces per milliliter of the waste water inside the second aeration tank. In the membrane treatment process 104, treated water cleaned through the first aeration tank is filtered and a radioactive material contained in the waste water is removed. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
