The invention relates to a marine
sewage treatment integrated device on the basis of biological moving beds, which comprises a
grating, a regulating basin, two stages of biological moving beds, a
sedimentation tank, a
backwashing water tank, an external membrane module, a
reagent bucket and an
ultraviolet disinfector.
Sewage sequentially enters the regulating basin, the two stages of biological moving beds and the
sedimentation through the
grating. Supernatant fluid can be disinfected by
ultraviolet rays and be directly discharged and can also be disinfected to be reused as recycled water after entering the membrane module. The external membrane module is connected with the
backwashing water tank and can be used for effectively preventing a membrane from being blocked. The
ultraviolet disinfector not only can be arranged behind the
sedimentation tank, but also can be arranged behind the membrane module so as to meet different drainage requirements. The membrane module is kept working normally by regular
backwashing and
medicine washing. Due to the adoption of the marine
sewage treatment integrated device on the basis of biological moving beds, the biodegrability of
organic matter is effectively strengthened,
effluent can directly reach the standard to be discharged after passing through the sedimentation tank, and the high efficiency degradation on marine domestic
wastewater is realized. The marine
sewage treatment integrated device has simple and reasonable structure and good working performance. The defect of short service life of the membrane module is overcome. Compared with a like reactor, the marine
sewage treatment integrated device has obviously improved
sewage treatment capability.
