以无纺布平板膜生物反应器为试验装置，采用通量阶梯式递增法的临界通量进行了测定，研究了混合液污泥浓度（MLSS)对无纺布膜临界通量的影响，考察了膜通量对无纺布平板膜生物反应器长期运行的影响。试验结果表明，无纺布膜的临界通量与 MLSS 浓度成反比，当 MLSS 的质量浓度从3 g / L 增长到9 g / L 时，无纺布膜临界通量从17 L/（m2·h)下降到13 L/（m2·h)。在 MLSS 的质量浓度控制为5 g / L，膜通量低于临界通量15 L /（m2·h)的条件下，无纺布平板膜生物反应器可连续稳定运行130 d，且反应器出水各项指标均可满足 GB / T 18920-2002《城市污水再生利用城市杂用水水质》标准的要求。

With non-woven flat sheet membrane reactor as the experimental equipment, the critical flux of non-woven membrane was determined using flux-step method, the influence of mixed liquid suspended solids (MLSS) on critical flux of non-woven membrane was studied with the influence of membrane flux on the long-period operation of the said reactor investigated at the same time. The results of the test showed that, critical flux of non-woven membrane was inversely proportional to the MLSS concentration. With the mass concentration of MLSS increased from 3 to 9 g/L, the critical flux of non-woven membrane decreased from 17 to 13 L/(m2·h). Under the condition that, the mass concentration of MLSS was 5 g/L, the membrane flux was lower than critical flux(15 L / (m2·h)), the stable operating period of the non-woven flat sheet membrane reactor could be as long as 130 d, furthermore, the effluent water quality of the reactor could meet the requirement of GB/T 18920-2002 The Reuse of Urban Recycling Water--Water Quality Standard for Urban Miscellaneous Water Consumption.
