摘要： A fluidized bed reactor for ammonia laden wastewater includes a column, a plurality of carrier particles, a first settling tank and a fluidizing means. The column defines a fluidizing chamber therein, and the fluidizing means is adapted for introducing the ammonia laden wastewater into the fluidizing chamber and further into the first settling tank. The reactor is further provided with microorganisms including nitrifying bacteria, anammox bacteria and heterotrophic denitrifying bacteria attached to the carrier particles. Nitrification reaction, anammox reaction and heterotrophic denitrification reaction are simultaneously taking place in the fluidizing chamber to transform ammonia into nitrogen by the microorganisms. A method for treating ammonia laden wastewater is also provided. The fluidized bed reactor is advantageous in the fact that its start-up is significantly shortened and it is adapted to efficiently treat thin ammonia laden wastewater.

摘要： A common final clarifier is provided downstream of a two-stage activated sludge (AS) system that includes a flow equalization basin (FEB) reactor and a nitritation reactor as the first AS stage and an anammox reactor as the second AS stage. A first return activated sludge (RAS) flow is conducted from the final clarifier to the first AS stage with a low flow rate and a second segregated RAS flow is conducted to the second AS stage with a high flow rate. The FEB reactor is operated as an anoxic reactor to achieve carbonaceous BOD removal; conversion of organic nitrogen to ammonia nitrogen; and, denitrification of recycled nitrite or nitrate nitrogen. The nitritation reactor is operated as an aerobic reactor to achieve oxidation of ammonia nitrogen to nitrite nitrogen by biological nitritation. The anammox reactor is operated at zero or very low dissolved oxygen concentration to achieve nitrogen removal by deammonification.

摘要： A flow equalization reactor for a multi-stage activated sludge process for treating industrial wastewater and/or municipal sewage is divided into two or more treatment zones. An outflow from a first treatment zone is mixed with an outflow from the second treatment zone in a mixer and conveyed to a third stage reactor containing anaerobic, autotrophic ammonia oxidizing anammox bacteria for converting nitrite nitrogen to nitrogen gas. The relative amounts of the outflows from the first and second treatment zones are controlled to promote and optimize the growth and accumulation of the anammox biomass in the third stage reactor.

摘要： Moving bed media serving as a growth surface for bacteria that remove soluble carbonaceous BOD, soluble inorganic ammonia nitrogen, phosphorous, nitrate nitrogen or nitrite nitrogen from wastewater are contained in a variable liquid depth, variable volume, hydraulic flow equalization basin. The equalization basin can be divided into different treatment sections by installing separator screens. Fat accumulation on the moving media, which could cause the media to float or in some other way cause the media to be ineffective, can be prevented by a fat, oil, and grease removal process in a dissolved air flotation cell upstream of the flow equalization basin containing the moving bed media. The moving bed media are retained in the basin by a suitable media screen as the liquid level and volume increases or decreases in the basin depending upon the effluent pumping rate vs. the influent flow rate.

摘要： Process for treating effluents containing nitrogen in ammonium form, using a sequential biological reactor (1), according to which: a volume of effluents to be treated in one complete cycle is introduced into the biological reactor in one or more successive fractions by volume, each fraction by volume being treated during a subcycle; each subcycle comprises a phase of feeding with a fraction by volume, and at least a first aerated step, during which total or partial oxidation of the ammonium to nitrites takes place by injection of air or of oxygen into the effluent, a settling out and emptying step taking place after the end of the complete cycle; the weight of N—NH4 to be treated is determined from the volume of effluents in the reactor at the end of the feeding phase, and from the difference between the initial N—NH4 concentration in the reactor and a concentration desired at the end of the aerated step, a maximum aeration time TM is dedicated to the aerated step, and an initial air flow rate Qairinit, for the beginning of the aerated step, is determined by taking into account the weight of N—NH4 to be treated and the maximum aeration time TM.

摘要： A method and installation for treating wastewater containing ammonia includes feeding activated sludge from an aeration tank into a hydrocyclone. The sludge is separated into a specifically heavy fraction containing mostly anaerobic ammonia-oxidizing bacteria (anammox) and a specifically light fraction containing mostly aerobic oxidizing bacteria (AOB), which are returned to the aeration tank. The hydrocyclone includes a roughened inner wall surface for at least partially removing an organic or inorganic cover layer disposed on the anaerobic ammonium-oxidizing bacteria (anammox).
