The invention discloses a domestic
sewage integrated anaerobic
ammonia oxidation-strengthened endogenous
denitrification SBBR
control system, and belongs to the field of biological
sewage treatment. The
system comprises a water tank and an SBBR reactor; after domestic
sewage enters the SBBR reactor,
denitrifying bacteria achieve a denitrifying effect by utilizing organic matters in the sewage, and redundant organic matters are stored
in vivo to synthesize an internal
carbon source; micro-
aeration is started after the reaction is ended; integrated anaerobic
ammonia oxidation reaction is performed on a
biological membrane; a DO sensor, a NH4<+> sensor, a NO2 sensor and a NO3 sensor acquire signals online, the DO concentration is controlled and the reaction time is adjusted via computer output; after the
aeration is completed, anoxic endogenous
denitrification is performed, the concentration of
nitrate nitrogen of outlet water is reduced, and static
settling is performed and water is discharged after the reaction is completed. According to the domestic sewage integrated anaerobic
ammonia oxidation-strengthened endogenous
denitrification SBBR
control system, the technical advantages of the SBBR
system and integrated anaerobic ammonia oxidation are played; the organic matters in the sewage are utilized, so that the SBBR
control system has the characteristics of
energy conservation, consumption reduction and
impact load resistance; meanwhile, the
system operation is optimized via online real-
time control; the
automation degree is high; the
controllability is high; advanced
nitrogen removal can be realized.
