Abstract

Gradual increase in the generation of wastewater results from the increasing global population. Thus, new treatment techniques and systems for controlling the treatment process depending on wastewater characteristics are desirable. This paper presents the use of a pilot-scale modified five-stage Bardenpho process with a 10 m3/day capacity for the treatment of real municipal wastewater. The process was developed for this study, and the steady-state removal efficiencies for COD (chemical oxygen demand), TKN (total Kjeldahl nitrogen), NH4-N (ammonium nitrogen), PO4-P (phosphate phosphorus), SS (suspended solids), and VSS (volatile suspended solids) were 87±5%, 86±12%, 93±14%, 89±9%, 88±8%, 94±4%, and 94±4%, respectively. In the study, the effluent COD, TKN, and TP concentrations were also estimated using a fuzzy logic approach. The results showed that coefficients of determination are higher than 0.80 suggesting that the presented fuzzy logic approach may confidently be used for the estimation of the treatment performance.

基于模糊模型的改良五段式巴登富工艺去除生活污水中的碳和营养物

由于全球人口不断增加，废水的排放量逐渐增加。因此，根据废水特性控制处理过程的新处理技术和系统是可取的。本文介绍了一种中试规模的改良五阶段巴登富工艺，其处理实际城市污水的能力为10立方米/天。该工艺对COD(化学需氧量)、TKN(总凯氏定氮)、NH4-N(铵态氮)、PO4-P(磷酸磷)、SS(悬浮物)和VSS(挥发性悬浮物)的稳态去除率分别为87±5%、86±12%、93±14%、89±9%、88±8%、94±4%和94±4%。采用模糊逻辑方法对出水COD、总氮(TKN)和总磷(TP)浓度进行估算。结果表明，确定系数均大于0.80，表明所提出的模糊逻辑方法可以可靠地用于评价处理效果。
