Abstract：
Biological approaches and coagulation are frequently used to reduce the chemical oxygen demand (COD) for treatment of ceramic effluent water. The technology known as the moving bed biofilm reactor (MBBR) can accomplish this goal. Further, the process of emulsification-aided innovative MBBR using biosurfactants can be proposed for ceramic effluent treatment. In a step-by-step upgrading scheme, biosurfactants and a consortia of halophilic and halotolerant microbial culture was utilized for the treatment of the effluent water. Over the course of 21 days, a progressive decrease in COD of up to 95.79% was achieved. Over the next 48 h period, the biochemical oxygen demand (BOD) was reduced by 98.3%, while total suspended solids (TSS) decreased by 79.41%. With the use of this innovative MBBR technology, biofilm formation accelerated, lowering the COD, BOD, and TSS levels. This allows treated water to be used for further research on recycling it back into the ceramics sector and repurposing it for agricultural purposes. PRACTITIONER POINTS: Implementation of modified MBBR technology for the treatment of effluent water. Biosurfactants could reduce in the organic and inorganic loads. Increase in MLSS values with COD removal observed. The plant operations without the use of chemical coagulants was effective with biosurfactants. Biofilm formation on carriers was scraped and the presence of surfactin and rhamnolipid was confirmed.
摘要：
生物方法和混凝经常用于减少处理陶瓷废水的化学需氧量（COD）。称为移动床生物膜反应器(MBBR)的技术可以实现这一目标。Further,使用生物表面活性剂的乳化辅助创新MBBR的工艺可用于陶瓷废水处理。在逐步升级方案中，生物表面活性剂和嗜盐和耐盐微生物培养物的聚生体用于处理废水。在21天的过程中，COD逐渐降低高达95.79%。在接下来的48小时内，生化需氧量(BOD)降低了98.3%,而总悬浮固体（TSS）下降了79.41%。通过使用这种创新的MBBR技术，生物膜形成加速，降低COD,BOD,和TSS水平。这使得处理过的水可以用于进一步的研究，将其回收回陶瓷行业，并将其重新用于农业目的。实践要点：实施改良的MBBR技术处理废水。生物表面活性剂可以减少有机和无机负荷。观察到MLSS值随着COD去除而增加。不使用化学凝结剂的工厂操作对生物表面活性剂有效。刮除载体上的生物膜形成,并确认表面活性素和鼠李糖脂的存在。
