Cost-effective treatment of dyeing wastewater remains a challenge. In this study, a newly designed hydrolysis acidification flat-sheet ceramic membrane bioreactor (HA-CMBR) was used in treating high-strength dyeing wastewater. The start-up phase of the HA-CMBR was accomplished in 29 days by using cultivated seed sludge. Chemical oxygen demand (COD) removal rate reached about 62% with influent COD of 7800 mg/L and an organic loading rate of 7.80 kg-COD/(m³·d). Chromaticity removal exceeded 99%. The results show that the HA-CMBR has good removal performance in treating dyeing wastewater. The HA-CMBR could run with low energy consumption at trans-membrane pressure (TMP) <10 kPa due to the good water permeability of the flat-sheet ceramic membrane. New strains with 92%⁻96% similarity to , sp., sp., and were identified in the HA-CMBR. Microbial population analysis indicated that sp., , sp., sp., sp., and sp. dominated in the HA-CMBR.
处理染色废水的经济有效方法仍然是一个挑战。在本研究中，采用新型水解酸化平板陶瓷膜生物反应器（HA-CMBR）处理高强度染色废水。采用培养的种子污泥，经过 29 天的启动阶段，HA-CMBR 的化学需氧量（COD）去除率达到约 62%，进水 COD 为 7800mg/L，有机负荷为 7.80kg-COD/（m³·d）。色度去除率超过 99%。结果表明，HA-CMBR 对处理染色废水具有良好的去除性能。由于平板陶瓷膜具有良好的水渗透性，HA-CMBR 可以在跨膜压力（TMP）<10kPa 下以低能耗运行。在 HA-CMBR 中鉴定出与 、 sp.、 sp.和 相似性为 92%-96%的新菌株。微生物种群分析表明，HA-CMBR 中主要存在 sp.、 、 sp.、 sp.、 sp.和 sp.。
