| titleOfInvention | Method and apparatus for purifying high-concentration organic wastewater |
| abstract | [PROBLEMS] To efficiently purify high-concentration organic wastewater and wastewater containing hardly decomposable substances without increasing the biological activity of microorganisms without adversely affecting the living environment of microorganisms in an aerobic biological treatment tank (aeration tank). Providing a method and apparatus for obtaining. A pH <5 or pH> 8, BOD 20 / BOD 5> 1.5, COD> BOD, BOD: N: P> 100: 15: 5, BOD> 6000ppm, SS> 2000ppm, n-Hex> In order to treat 100 ppm of high-concentration organic wastewater by the activated sludge method, the wastewater is treated in the solid-liquid separation device 8 and the raw water adjusting tank 3 at 5.5 ≦ pH ≦ 7.5, BOD 20 / BOD 5 ≦ 1.5, COD ≦ 0.5 × BOD, BOD: N: P ≦ 100: 15: 5, BOD ≦ 5000 ppm, SS ≦ 1000 ppm, n-Hex ≦ 50, then introduced into aeration tank 4 for aerobic biological treatment .
