Domestic Wastewater Treatment By Package MBR Sewage Treatment Plant
Product Description
MBR is the abbreviation of Membrane Bio-Reactor, which is a
brand-new efficient sewage treatment process produced by the
organic combination of modern membrane separation technology and
traditional biological treatment technology.
The MBR process organically combines the membrane separation
technology in the separation project with the traditional
wastewater biological treatment technology, which not only
eliminates the need for the construction of secondary sedimentation
tanks, but also greatly improves the solid-liquid separation
efficiency. Moreover, due to the mass concentration of activated
sludge in the aeration tank The increase in sludge and the emergence of special bacteria
(especially the dominant flora) in the sludge increase the rate of
biochemical reactions. At the same time, by reducing the F/M ratio to reduce the amount of
surplus sludge produced (or even zero), so as to basically solve
many outstanding problems existing in the traditional activated
sludge method.
Process characteristics
Compared with other biological treatment processes, membrane
bioreactor technology has many obvious advantages, and its
characteristics are as follows:
1) Solid-liquid separation can be carried out efficiently, the
separation effect is far better than the traditional sedimentation
tank, the effluent quality is good, the suspended solids and
turbidity are close to 0, and it can be directly reused to realize
the recycling of sewage;
2) The high-efficiency interception effect of the membrane enables
microorganisms to be completely trapped in the reactor, which
realizes the complete separation of the hydraulic residence time
(HRT) and the sludge age (SRT) of the reactor, making the operation
control more flexible;
3) The microbial mass concentration in the reactor is high, and the
impact load is resistant;
4) It is conducive to the growth and reproduction of
slow-proliferating nitrifying bacteria, and the system
nitrification efficiency can be improved. It has the function of
nitrogen and phosphorus removal by changing the operation mode.
Based on obove waste water characteristice, the plant is designed
to achieve the following outlet standard
| Item | Inlet water quality(mg/l) | Outlet water standard(mg/l) |
| COD | <2380 - 8942 | <30-75 |
| BOD | <600-850 | <50 |
| TSS | <189 - 3330 | <25 |
| PH | 6.7 | 6.5~8.5 |
| O&G | 215 | <10 |
