摘要： PROBLEM TO BE SOLVED: To provide a method of operating a denitrification reactor which recovers the denitrification performance of the denitrification reactor, reducing nitrate nitrogen or nitrite nitrogen in wastewater to nitrogen using methanol as a hydrogen donor by denitrifying bacteria, in a short period of time when the activity of various germs are increased and the denitrification performance of the denitrification reactor is decreased. SOLUTION: In the denitrification reactor which reduces nitrate nitrogen or nitrite nitrogen in wastewater to nitrogen using methanol as a hydrogen donor by denitrifying bacteria, when the activity of various germs are increased and the denitrification performance of the denitrification reactor is decreased, a part of methanol is substituted by acetic acid, and a mixture of the methanol and acetic acid is subjected to pH adjustment, and then supplied to the denitrification reactor as a hydrogen donor. As the acetic acid decreases the activity of the various germs, the activity of the denitrifying bacteria is increased to recover the denitrification performance in a short period of time.

摘要： PROBLEM TO BE SOLVED: To provide a denitrification apparatus and a biological nitrification and denitrification apparatus which are suitable for miniaturization.
SOLUTION: A liquid cyclone 17 recovers suspended particulate organic materials contained in wastewater and the recovered suspended particulate organic materials are sent to a UASB reactor 7. The suspended particulate organic materials become a core of granule sludge 29, which allows the granule sludge 29 to stably grow and maintains the granule sludge 29 at high concentration, thereby stabilizing denitrification performance. An SSB reactor 9 is horizontal and thin and maintains the inside thereof in an aerobic condition in cooperation with a siphon 47, which simplifies the configuration of the apparatus. As a result, the biological nitrification and denitrification apparatus 1 can be miniaturized.
