Process Flow Description
Recycle-water Treatment Process Flow
First, the bulky grains such as the suspended substance and
battings are removed from the washing sewage; then water quality
and amount balancing is carried out in the adjusting pool, while
heavy kernels such as sediments are precipitated. Second, the
sewage is pumped into the MBR by a lift pump, where the
high-density activated sludge carries out complete and effective
deterioration to the organic matters in the sewage. Last, the
treated water is discharged into the reservoir for recycling after
it is filtered and collected by the membrane module, while the mud
is totally trapped in the reaction tank and to be discharged
periodically. The whole process is in PLC automatic control. |
MBR—Water Treatment Revolutionary Technology
Fundamental principles of MBR: MBR is an organic combination of
membrane separation technique and biotechnology. It uses
hyperfiltration and microfiltration membrane separation technology
instead of the second pond and normal filtration unit of the
traditional activated sludge process, and can make the HRT and SRT
totally separated. Its high-efficient solid-liquid separation
capaurban makes the water quality good and the suspended substance
and the turbidity nearly zero, additionally, it can trap biotic
pollution substance such as colon bacillus and make the treated
water able to be recycled directly. This equipment is especially
suitable to the reclaimed water recycling treatment and is an
excellent application of the 21st century high-tech in water
treatment.
Features of MBR
MBR is a new product combining membrane separation technique and
biotechnology.
The high-efficient solid-liquid separation effect is far better
than the traditional sedimentation pool with good water quality and
the suspended substance and turbidity nearly zero. The treated
water can be recycled directly and the equipment has realized
sewage reclamation.
Membrane high-efficient interception function makes the
microorganism completely trapped in the reactor, the circuit
reactor HRT and SRT totally separated, and the running control more
flexible and stable.
The microorganism in the reactor is of high density shockproof.
It is helpful to the interception and growth of the slow
proliferated nitrobacteria and brings up the systematic nitration
efficiency. Some changes in the operation mode also have
denitrification and dephosphorization functions.
The equipment has long SRT. Membrane separation makes the
macromolecule in the sewage difficult to be deteriorated, so it has
sufficient detention time in the limited biological reactor, and
the deterioration rate of the organic matter is greatly enhanced.
The reactor is operated in high capaurban load and low mud load
with less mud left and long mud disposal period, leaving no excess
mud to be disposed.
The system adopts PLC control which can realize full process
automation control.
Application Scope
Urban sewage deep treatment. The treated water can be used directly
in watering plants, flushing the toilet, treating the landscape and
washing cars.
The intermediate water projects of industrial and mining
enterprises, hotels, hospitals, office buildings, residential
communities, etc.
The sewage reusing treatment of laundry plants (rooms) and car
washing. |
