MBR for wastewater treatment, as compared with the conventional sewage treatment, has the following advantages: ◆ efficient solid-liquid separation, the separation effect is much better than traditional sedimentation tanks, water quality is good, effluent suspended solids and turbidity close to zero, can be directly reused to achieve wastewater recycling. ◆ efficient membrane interception, microbial completely trapped in the bioreactor to achieve reactor HRT and SRT complete separation, biological treatment effect becomes more stable. ◆ Because the aeration tank traditional MBR wastewater treatment combined with secondary settling tank and replace the entire process of tertiary treatment facilities, and therefore can significantly reduce footprint, saving construction investment. ◆ beneficial nitrifying bacteria retention and reproduction, high nitrification efficiency, by changing the operating mode also has nitrogen and phosphorus removal. ◆ Because SRT can be very long, thus greatly improving the efficiency of refractory organics degradation. ◆ reactor at high volume load, low sludge load, SRT long run, the remaining sludge production is very low. ◆ system to achieve automatic control, easy operation and management. Ultrafiltration membrane ultrafiltration membrane separation characteristics in technical areas, since the reverse osmosis separation accuracy to Linyi microfiltration hollow fiber membrane filtration continuous spectrum in the visible range, ranging between nanofiltration and ultrafiltration microfiltration. Ultrafiltration of the domain of molecular weight cutoff of about 500 to 500 000, corresponding to an approximate value of the membrane pore size 0.002μ ~ 0.1μ. MWCO membrane with pore size is no correspondence between the two. Simple to understand, an ultrafiltration membrane as a sieve, under a certain pressure (0.1 ~ 0.6mpa), allowing the solvent and solute through the membrane pore size less than, greater than the pore size of the solute is prevented through, to complete purification of the solution, separated and concentrated. Ultrafiltration process has the following characteristics: (1) no phase ultrafiltration interannual variability, can be separated at room temperature and low pressure, low energy consumption and therefore Weihai hollow fiber membrane, about evaporation and freezing 1/2 ~ 1 / 5; (2) devices are small, simple structure, low cost investment and therefore hollow fiber membrane, easy to implement; (3) ultrafiltration process simply conveying pressurized liquid, the process is simple, easy operation and management; (4) the solution In isolation, a qualitative change in the enrichment process does not occur, and thus suitable for processing in taste and heat-sensitive solution; (5) suitable for recovering valuable trace separation of macromolecules from dilute solutions recovery and low concentrations of macromolecules; ( 6) of different molecular weight species can fractionation; (7) ultrafiltration membrane is homogeneous continuum from polymer made, without any impurities in the course of the hollow fiber membranes ZAOZHUANG off, to ensure the purity of the solution to be treated . From the above separation characteristics, ultrafiltration wide range of applications, but in the final analysis, the solution is mainly used in the purification, separation and concentration.
