摘要： Described herein are attached growth reactor systems which increase nitrifying bacteria biomass through a variety of means during warm weather. As a consequence, the attached growth reactor system contains sufficient nitrifying bacteria biomass to remove ammonia from wastewater in cold to moderate climates. In one example, there are two attached growth reactors into which wastewater is distributed discontinuously. Specifically, wastewater is transferred to the first attached growth reactor for a first period of time and then is transferred to the second attached growth reactor for a second period of time during warm weather which effectively doubles the nitrifying bacteria biomass in the system. During cold weather, approximately half of the wastewater is applied to each reactor simultaneously.

摘要： The reduction of only the soluble fraction of organic matter prior to SND systems enhances nitrification rates while still providing residual particulate and colloidal organic matter to sustain denitrification in SND systems. Surprisingly, by increasing the amount of soluble organic matter reduced by conversion to biomass or microbial product and decreasing the amount of soluble organic matter reduced by oxidation to carbon dioxide prior to SND zones will still enhance nitrification rates while providing even more particulate and colloidal organic matter to improve denitrification in the SND zones.

During cold weather, wastewater can be applied to the reactors according to their increased nitrifying bacteria biomass, that is, according to their increased capacity to treat influent wastewater compared to standard operations.
