The invention relates to the technical field of
water treatment equipment, and particularly relates to a multifunctional integrated
sewage treatment device which sequentially comprises a control cabinet, an anoxic zone, an aerobic zone, an anaerobic zone, an anaerobic gas stripping
reflux tube, a membrane treatment device, a
precipitation zone and a
precipitation gas stripping
reflux pipe, whereinthe anaerobic gas stripping
reflux tube enters the anoxic zone from the anaerobic zone, the membrane treatment device is arranged in the aerobic zone, the
precipitation zone is connected to the aerobic zone, and the precipitation gas stripping reflux
pipe enters the anoxic zone from the
sedimentation zone. The invention further discloses a multifunctional integrated
sewage treatment method, and the precipitation and membrane treatment can be selected according to different water levels. According to the multifunctional integrated
sewage treatment device and the multifunctional integrated
sewage treatment method, an intelligent process switching
system and a
processing technology are adopted aiming at the characteristics that the fluctuation of the
water quality and the water quantity of the town domestic sewage is large and the like, the automatic switching of the process is realized, the stable operation of the equipment is ensured, and the standard effect of the
water quality is ensured while the stable operation of the equipment is ensured.
