Abstract：
The presence of a large amount of organic and inorganic pollutants in dairy effluent is a substantial environmental issue. This study investigated electrocoagulation (EC) as a potential treatment method for dairy wastewater under different operating conditions, such as applied voltage (5-25 V), electrolysis time (30-90 min), and inter-electrode distance (1-2 cm) by using aluminum electrodes. This study focuses on achieving the maximum removal of BOD, COD, and nitrate in dairy effluents with the aforementioned operating conditions. The process was optimized using the response surface methodology (RSM) and Taguchi method. RSM method optimized the electrocoagulation operating conditions such as the voltage at 23.75 V, time of 90 min, and inter-electrode distance at 1.07 cm. This optimization achieved the maximum removal percentage of BOD, COD, and nitrate at 79.06%, 84.35%, and 79.64%, respectively, in dairy effluent. Taguchi method optimized the electrocoagulation parameters such as the voltage at 25 V, time duration of 90 min, and inter-electrode distance of 1.00 cm, showcasing improved removal percentages of BOD, COD, and nitrate as 90.54%, 89.28%, and 82.74% respectively. The current study attempts to understand the optimization efficiencies between Taguchi method and response surface method for diary wastewater treatment.
摘要：
乳品废水中大量有机和无机污染物的存在是一个实质性的环境问题。本研究探讨了在不同操作条件下，电凝聚（EC）作为乳品废水的潜在处理方法。如施加电压（5-25V），电解时间（30-90分钟），和电极间距离(1-2cm)通过使用铝电极。本研究的重点是实现BOD的最大去除，COD,COD在上述操作条件下，乳制品废水中的硝酸盐和硝酸盐。使用响应面方法(RSM)和Taguchi方法对工艺进行了优化。RSM方法优化了电凝操作条件，例如23.75V的电压，时间90分钟，和电极间的距离在1.07厘米。该优化实现了BOD的最大去除百分比，COD,COD硝酸盐含量为79.06%，84.35%,和79.64%，分别,在乳品废水中。Taguchi方法优化了电凝参数，例如在25V下的电压，90分钟的持续时间，电极间距离为1.00cm，展示改进的BOD去除百分比，COD,COD硝酸盐为90.54%，89.28%，和分别为82.74%。当前的研究试图了解田口方法和响应面法在日记废水处理中的优化效率。
