The efficient process structure for plant area's production waste water and high-salt wastewater of this structure, the MBR in MBR membrane cisterna 10 are flat Piece membrane module is placed in aeration tank, the water after aerobic aeration and biological treatment, by pump by extracting out after membrane filtration.Its benefit With membrane separation plant by biochemical reaction tank activated sludge and larger molecular organics matter retain, save secondary settling tank.It is active dirty Therefore mud concentration greatly improves, hydraulic detention time (HRT) and sludge retention time (SRT) can be controlled separately, and difficult to degrade Substance in the reactor constantly react, degrade.Since the presence of MBR film substantially increases the ability of system separation of solid and liquid, from And it is discharged system, water quality and volumetric loading are all greatly improved, and the high water water standard after film process (is more than country Level-one A standard), by disinfection, water quality and the high high quality reuse water of biological safety are eventually formed, it can be directly as new unboiled water Source.Due to film filtration, microorganism is completely trapped in MBR membrane bioreactor, realizes hydraulic detention time and work Being completely separated for property sludge sludge age, eliminates sludge bulking problem in traditional activated sludge process.Membrane bioreactor has to dirt It is strong to contaminate object removal efficiency height, nitrification ability, can be nitrified simultaneously, denitrification, denitrification effect are good, stable effluent quality, residue Sludge yield is low, facility compact, occupied area few (the only 1/3-1/2 of traditional handicraft), increment dilatation are convenient, the degree of automation High, simple operation and other advantages.

Membrane filtration pattern in the NF/RO film 12 of this structure is cross-flow filtration, i.e. filtering produces water flow and flows to concentrate Not in the same plane, pollution (the molecular weight cut off grade of reverse osmosis membrane of the pollutant to film in effective reduction filter process For 20D, i.e., reverse osmosis membrane 0.1nm pore size filter can guarantee that material grains of the film to molecular weight greater than 20D have 92% with up Except rate；The cutting of nanofiltration membrane divides force level to be 200D, i.e., nanofiltration membrane 1nm pore size filter can guarantee that film is greater than molecular weight The material grains of 200D have 90% or more removal rate).

When the processing operation of this structure, production waste water first crosses the oil and suspended matter of air-flotation process removal wherein most, then Cr VI therein and other heavy metal ion are removed by reduction/neutralization/coagulation-settlement process；Then into A/O+ Formula MBR system is set, it is using the metabolism of microorganism that the organic pollutant decomposition and inversion in sewage is inorganic for small molecule Object, to guarantee heavy metal ion zero emission requirement in effluent quality, the rear end MBR designs nanofiltration+reverse osmosis process and produces water to MBR It is further processed, removal hardly degraded organic substance and most of salinity substance.

Present treatment structure, the haline water first that incineration plant flue gas washing sewerage generates enter high-salt wastewater conditioning tank, It is handled by triple effect evaporator 17 again, evaporation water outlet is delivered to biological aerated filter 18 and is handled, and is finally discharged Reach quality of reused water standard heel row to reuse pool 13.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art It for art personnel, without departing from the principle of this utility model, can also make several improvements, these improvement also should be regarded as The protection scope of the utility model.
