Portable Domestic Integrated Sewage Treatment Equipment Underground
Domestic Wastewater
Product Description
1. Membrane Bioreactor (MBR) is a kind of advanced technology
developed since the end of 20th century which realized the
efficient combination of membrane separation technology with
biological technology.
2. The membrane separation technology replaces the traditional
active sludge method and the normal filter unit, its strong
separation ability can make the SS turbidity near to be zero.
Hydraulic retention time (HRT) sludge age (SRT) is completely
separated, the outlet water is good and stable in quality, it can
be reused without the third level treatment.
3. Due to the high security and economic and effective water, it
greatly expands the scope of application of waste water recycling.
Main Features
1. The MBR can make the biomass in biological treatment unit
maintain high concentration, thus highly improve the volume
loading. Meanwhile, the high efficient membrane separation can
shorten the HRT. The device is with a compact structure and small
space occupation.
2. MBR can filter out bacteria, part of the harmful material such
as virus, it can obviously save dosing disinfection dosage, greatly
improve the quality of the output water and reduce the operating
cost and widen the scope of application of water.
3. Due to the strong interception function of MBR, it can keep the
microbe in the reactor to avoid the loss of all kinds of microbe
groups, which is good for the growth of the bacteria (such as the
nitrifying bacteria), at the same time, it can lengthen the
residence time of difficult degradable macromolecule organics to
improve the decomposition so as to make the metabolic system
process smoothly. The system has a strong impact resistance and
wide suitability.
4. It can realize the completely separation of HRT and SRT. By the
extended aeration, it can consume the organics, it can
theoretically achieve the effect of no excess sludge emissions,
thus reduce the surplus sludge treatment costs significantly.
5. The unique mode of operation makes the membrane surface no
blocking, and the cleaning interval time is long. The way to clean
the membrane is easy, since the membrane module can be separately
cleaned, thus, the maintenance is convenience and simple.
6. Because of the high-efficiency solid-liquid separation, it can
efficiently remove the SS, colloidal material and dead microbe in
the sewage, no need sedimentation tank, or filter device, nor other
solid-liquid separation device.
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 |
Application
Hotel, restaurant, sanatorium, hospital;
Factory, mining, military camp, scenic spots;
Small village/town;
Station, airport, port;
Industrial organic waste water similar with domestic waste water.
