摘要： A total nitrogen (TN) removal device for sewage and its operation method. The TN removal device includes a denitrification tank, a supplementary reaction zone filled with aerobic granular sludge and a sedimentation and separation zone. The supplementary reaction zone and the sedimentation and separation zone are arranged inside the denitrification tank, and communicated through a three-phase separator. The sedimentation and separation zone is located above the supplementary reaction zone. A top of the sedimentation and separation zone is greater than its bottom. A membrane aerated biofilm reactor (MABR) assembly is arranged in a space formed by outer walls of the sedimentation and separation zone and supplementary reaction zone and an inner chamber of the denitrification tank. A side wall of the denitrification tank is provided with a chemical oxygen demand (COD) detector and a nitrate nitrogen detector.

摘要： Methods and systems for controlling nitrous oxide production in a wastewater treatment facility in which wastewater is treated with microbes in a biological reactor. Nitrous oxide production can be controlled by determining an amount of two or more nutrients in the biological reactor, calculating a value that represents a comparison of the values, comparing the calculated value to a threshold value, and optionally taking a corrective action to reduce nitrous oxide production based on the comparison. In one aspect, nitrous oxide production can be controlled by determining an amount of ammonium in the biological reactor, determining an amount of a nitrogen compound that can include nitrite, nitrate, and/or hydroxylamine, calculating a value that compares the amount of ammonium to the amount of the nitrogen compound, and taking a corrective action that changes a system parameter to reduce the nitrous oxide production if the calculated value surpasses a threshold limit.
