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.
