Embodiment 1
[0042] Example 1: A self-rotating anaerobic forward osmosis membrane bioreactor
[0043] Figure 1-3 It is a schematic diagram of a self-rotating anaerobic forward osmosis membrane bioreactor and components of the present invention, the reactor includes a water inlet tank 1, a membrane reaction device 6, a draw liquid tank 11, and an RO membrane treatment device 9; the water inlet tank 1 The water inlet pump 2 is connected to the membrane reaction device 6, the upper part of the membrane reaction device 6 is sealed, and is connected to the water sealing device 7 through a pipeline. The membrane reaction device 6 includes a vane type FO membrane module 3 and an MF membrane module 4, Wherein, the MF membrane module 4 is connected with the suction pump 5, and is used to discharge the dissolved salt in the reactor, so as to control the salinity in the reactor at a lower level, and the suction pump 5 is located at the end of the membrane reaction device 6 External: the vane type F...
Embodiment 2
[0051] Embodiment 2: Utilize the spin AnOMBR of the present invention to carry out organic wastewater treatment
[0052] use as figure 1 A spin-on AnOMBR of the structure shown, operated at a moderate temperature of 35 °C.
[0053] The water quality indicators of alcohol wastewater are: COD: 3300±53.23mg / L, TOC: 1590±102.50mg / L, NH 4 + -N: 78.02±6.77 mg / L, TP: 19.12±2.11 mg / L. The blade type FO module and the flat type MF membrane module used for the membrane module are made of triacetate fiber (CTA) and polyvinylidene fluoride (PVDF) respectively, and the membrane area is 0.018m 2 and 0.035m 2 , wherein the average pore diameter of the MF membrane is 0.2 μm, and the number of FO membrane units of the vane-type FO membrane module is four.
[0054] The water inlet pump 2 pumps the water from the raw material liquid pool 1 into the membrane reaction device 6, and a part of the mixed liquid passes through the vane-type FO membrane module 3 under the action of the drawing liq...
