Introduction

The integration of sewage treatment plant after years of practice, gradually improved a specifically for the area away from the urban sewage pipe network, and should not built in the local construction of sewage treatment plant,is an independence, integration, no personnel operating sewage treatment device.

It's outlet water quality is higher than national discharge standard.

Applicable to the tourist area, scenic spot, villa community, resorts, nursing homes, troops, rural, etc.

Small sewage treatment equipment using Membrane Bioreactor (be Bioreactor, referred to as the MBR) technology is combined biological treatment with Membrane separation technology, it is a kind of new technology, to replace the traditional process of the second pond, it can efficient solid-liquid separation, get the stability of the direct use of water. But also to maintain a high concentration of microorganisms in the biological in the pool, process less excess sludge, effectively remove ammonia nitrogen, suspended solids and turbidity water was close to zero, the bacteria and viruses in water is removed significantly and low energy consumption, cover an area of an area small.

In the 70 s in the United States, Japan, South Africa, and many European countries had begun to use membrane bioreactor for sewage and wastewater treatment research. At present there are more than 1000 Japanese MBR in operation.(such as the water from sewage shower drainage, drainage of wash one's hands and drainage drainage, toilet, kitchen, laundry, drainage, etc.) and cooling water.

 

Scope of application
Similar industrial organic wastewater, such as textile, beer, paper making, leather making, food, chemical and other industries of organic wastewater treatment.My company's sewage treatment equipment have 5 t/d, 25 t/d, 50 t/d, 100 t/d, 150 t/d, 200 t/d, 300 t/d, 500 t/d specification, etc.

Process instructions
Sewage grille into regulating pool is entered into the bioreactor, lift pump by PLC controller open aerator oxygen filling, bioreactor effluent by the circulation pump into the membrane separation processing unit, return to adjust water pool.Backwash pump use wash in the pool to backwash of film processing equipment, processing water recoil sewage returns to adjust pool.

Through biological reactor water level control to promote the opening and closing of the pump.Membrane unit filter operation and backwash operations can be automatic or manual control.When membrane unit need chemical cleaning operation, shut off the water valve and sewage circulating valve, open the medicine and pharmaceutical circulation valves, start liquid circulating pump, chemical cleaning operations.

Membrane bioreactor (MBR process) is a membrane separation technology and biological technology organic combination of the new sewage treatment technology, it will use membrane separation equipment and biochemical reaction tank intercept live, activated sludge and macromolecular organic matter in early eliminate pond, and the second pond. Activated sludge concentration so greatly improved, hydraulic retention time and sludge retention time can be controlled separately, and refractory material constant reaction, degradation in the reactor, greatly strengthen the function of the bioreactor.


The technological characteristics 
(1) the microbial concentration can increase 2-3 times, biochemical can improve the efficiency of 10 ~ 30%.
(2) short hydraulic retention time and sludge (organic macromolecules colloidal particles) for a long time.
(3) save the second pond, the sludge thickener and disinfect pool.
(4) mud cycle is long.
(5) hollow fiber membrane life can reach more than 3 years; The service life of main equipment in more than 20 years.
(6) run automatically without personnel unattended.


 Long membrane element cleaning intervals.

 

The MBR process characteristics
Membrane bioreactor (MBR) is a kind of by the membrane separation unit combined with a biological treatment unit of the new water treatment technology, compared with traditional biochemical treatment technology, the MBR has the following main features: high processing efficiency, good water quality;Equipment is compact, cover an area of an area small;Easy to realize automatic control, simple operation and management.Since the 80 s, more and more attention, the technology become a hotspot in the research of the water treatment technology.At present, the membrane biological reactor has been applied in the United States, Germany, France, Japan and more than 10 countries such as Egypt, processing scale in 6 ~ 13000 m3 / d.
