A movable zero discharge system for advanced treatment of excrements and sewage is provided to purify organic suspended solids and eutrophication-causing materials contained in sewage, and to recycle purified treated water as toilet water without discharging the purified treated water to the outside. A movable zero discharge system for advanced treatment of excrements and sewage comprises a first aerobic reactor(7), a second aerobic reactor(54), a first advanced treatment tank(53), a second advanced treatment tank(52), a flow equalization tank(51), a wood chip bioreactor(55), a decoloring filter tank(41), and a treated water storage tank(45). The first aerobic reactor purifies sewage flown in through the transfer pipe by installing a transfer pipe(5) and a cutter pump(4) on a storage tank. The second aerobic reactor receives sewage discharged from the first aerobic reactor to purify nitrogen, phosphorous, and other organic suspended solids contained in the sewage. The first advanced treatment tank receives sewage discharged from the second aerobic reactor to primarily remove organic suspended solids, nitrogen, phosphorous, and color remained in the sewage. The second advanced treatment tank receives sewage discharged from the first advanced treatment tank to remove organic suspended solids, nitrogen, phosphorous, and color remained in the sewage. The flow equalization tank controls the quantity of sewage flown in from the second advanced treatment tank. The wood chip bioreactor finally removes nitrogen, phosphorous, and other organic suspended solids remained in treated water flown in through a transfer pipe(74). The decoloring filter tank receives treated water discharged from the wood chip bioreactor to remove color remained in the treated water. The treated water storage tank stores treated water transferred from the decoloring filter tank. |
