30m3d MBR Package Sewage Treatment Plant
MBR is a kind of brand new sewage treatment technics which combine Superfine filter components and bioreactor. membrane separation plant hold back the activated sludge and macromolecule in biochemical reaction basin, omit secondary settling pond. the sludge depth greatly improved, HRT and SRT can separately control, the nonbiodegradable material constant reaction ,degradation in reactor. Membrane bio-reactor system greatly intensify the bioreactor function by membrane separation.
Function and application scope
Function:
Already existing sewage treatment plant,running water factory upgrade,reform
Municipal sewage treatment plant,running water factory new instruction
pure water production pretreatment
Reuse of reclaimed water
Application scope:
Hotel,restaurant,community etc domestic sewage treatment recycle
Industrial and mining enterprises,remote village,sentry ,tourist area etc domestic sewage recycle.
Each kind of industrial sewage (similar to domestic sewage) :such as hospital sewage,pharmaceutical sewage ,washing sewage,food sewage etc
Item | Influent water quality | Effluent water quality |
BOD5(mg/L) | 400 | ≤10 |
CODcr(mg/L) | 600 | ≤40 |
SS(mg/L) | 200 | ≤10 |

Feature:
This system with containerized package function: make the anoxia tank,MBR bio-reaction tank,sludge tank cleaning water tank and operation room integrated into a big tank body, compact structure, process concise, small occupy area ( only traditional process 1/3-1/2) increment expansion convenient, high automatic degree, operating maintenance conciseness, it can move at anytime and anywhere, it can move to treatment goal location, direct large-scale to make proceed treatment, no need make twice construction.
Gather sewage treatment and water purification process into one system, it shallow buried underground or ground; the treatment basic no sludge generate, hasn’t influence to surrounding; better operation effect,high reliablity,effluent water quality steady,little operation cost.
In treating municipal sewage, impact resistance,high remove efficiency to pollutant, strong nitration ability, it can make nitration,denitrification, both nitrogen and phosphorus removal function, suitable for treat municipal sewage,distributed sewage, the effluent can be reuse or can be discharge after reach standard, it can meet different users of different water quality.
cleaning disinfection tank equip with packing which made of new type environmental protection active ion material, it has disinfection function and can effective remove the heavy metal ion in water, it can overcome medication washing disinfect caused secondary pollution and reduce the heavy metal content in effluent, greatly improve the recycle water quality.
The aeration pipeline of membrane bio-reactor divide two parts, 1 part is make aeration to surrounding activated sludge , another part is make aeration to membrane module.
Its advantage is to make the membrane module mutual flap by aeration membrane module produce scour force, thus it can shake off the calcified sludge adsorb in the membrane fenestra surface, make the membrane flux greatly extend the membrane service life, thus reduce operation cost.
MBR treatment process:
The sewage first pass by bar screen (mechanical bar screen or manual bar screen), bar space is 1-3mm, used to gain big particle suspended solid and impurity, then flow into equalize tank interior, to make the water quality,volume in equalize tank, then lift the sewage into anoxia tank by sewage lift pump, after hydrolytic acidify by anoxia tank, enter into MBR biochemical treatment system. Whole set of bio-chemical treatment system is composed of front pretreatment and reaction tank, according to influent water quality and effluent water quality requirements, which decide if need and design leading treatment end. In reaction tank equipment immersed plain film, constitute MBR- aerobic running mode.
MBR reaction tank effluent water direct enter into recycle tank, dosing disinfectant or adopt ultraviolet and activated ion material make infection, each item water quality index, discharge or pump into reclaimed water pipe network to recycle.
Main treatment unit
(1) Front pretreatment tank:
In front of this device is anoxia tank, in one end of anoxia tank set water inlet, another side top set water weir tank and outlet water, can make the sewage stable nature flow into membrane reaction tank, equip floating packing and anoxia sludge, the sludge in anoxia tank HRT is 3-8h, give oxygen by interval, to make acidify,nitration and denitrification function, make the organism gradate translate into inorganics remove.
(2)MBR bio-reaction tank:
It has set water inlet in one side, and the immersed flat membrane module set in reaction tank, accommodate activated sludge, around aeration and membrane unit aeration pipeline connect with air blower, the matched collecting pipe in membrane module connect with suction pump, the untreated sewage enter into MBR biochemical reaction tank by water inlet, sewage HRT is 5h in reaction tank. After degrade by activated sludge in reaction tank, by resistance pollutant flat membrane module, then enter into cleaning water disinfection tank by suction pump. There set sludge lifting pump in aeration, it can lift the surplus sludge to sludge digestion tank interior; there has overflow in reaction tank top, it can make the sewage backflow into tank outside equalize tank; in below side open vent , in order to convenient for tank interior maintenance, cleaning.
(3) Sludge tank:
there are set sludge collecting hopper and sludge pipeline in sludge tank bottom, in order to convenient for sludge concentration, set weir water tank in top, there open mud discharge inlet in bottom, rely on static pressure automatic discharge mud.
(4)Cleaning water tank:
(5) Operation room:
It set 2 pcs air blower in operation room, operate 12h automatic shift 1 time, air blower equip with silencer damping measures; suction pump 2pcs, electric control cabinet 1pc, lighting system; in the top, equip with rain-proof air vent and ventilate convection device.
The above treatment unit integrated in a tank body, electric control cabinet automatic control each power plant operation.
