A sewage processing device is provided to control relative lengths by connecting reaction sheets between a inlet side sheet box and outlet side sheet, to control time and range of the denitrification of nitrification, to reduce work time by increasing flow velocity with a reduced extension wall, and to use one reaction tank as an aeration tank for the nitrification and denitrification and an anoxic chamber. A plurality of walls(11) is formed to be crossed inside a wall(2) of a reaction tank(1). A storing groove(12) is formed in the end part of the wall(11). One end of the wall(21) is movably inserted into a storing groove(12) of a partition(10). A guide roller(30) is fixed to the end part of an extension wall(20) in order that upper and lower side of a roller pole is rotatable. A release preventive plate is fixed to upper and lower part of the roller pole at the fixed axis. A cylinder is fixed to the upper end of the wall(11) of the partition(10). The end part of a cylinder rod is fixed to the upper side of the wall(21) of the extension wall(20) and the cylinder moves the extension wall(20). A slit hole is perpendicularly formed in a case at one side and the sheet box(50) supplies the reaction sheet to outside or receives it. The fungi is adhered to the both sides of the flexible porosity sheet. Nitrifying bacteria is adhered to the sheet of the sheet box(50) at the inlet port(3) side. Denitrification bacteria is adhered to the sheet of the sheet box(50) at the outlet port(4) side. According to the measured value of the nitrogen and phosphorus measure system(80), a control box(70) operates three way valve(90), two motors, and the cylinder of which extension wall(20) is operated. The set value is changed by a control panel of the exterior part of a box. The nitrogen and phosphoric concentration are measured in the water ejected from the outlet(4) of the reaction tank(1) of the nitrogen and phosphorus measure system(80). Three way valves(90) sends the water, which is ejected to the outlet(4), to a pond(100) or the inlet port(3) of the reaction tank(1). |
