Abstract

Wastewater from a small animal slaughterhouse (SWW) was treated by a two-step process: coagulation/flocculation (CF) followed by continuous flow electrooxidation (CFEO). Initially, a coagulant dose of 0.8 kg/m3 in the CF process, using FeCl3 at pH 8.5, achieved 52% COD and 63% turbidity removal (effluent: 2000 mg/L and 65.2 NTU). Alum, (optimum pH = 6.5), yielded 50% COD and 55% turbidity removal (effluent of 2100 mg/L and 78.5 NTU). Subsequently, when employing the CFEO process following the CF process with FeCl3, the study achieved highly efficient results. Specifically, under optimum conditions (residence time in the CFEO reactor, τ = 240 min, wastewater feed rate to the reactor = 15 mL/min, and current density = 300 A/m2), the COD and turbidity removal efficiencies reached 99.60% (resulting in an effluent of 8 mg/L) and 99.9% (resulting in an effluent of <0.10 NTU), respectively. In conclusion, the CF + CFEO consecutive treatment process demonstrated remarkable treatment efficiencies, with COD and turbidity removal rates of 99.9% and 99.9%, respectively. Moreover, the total operating cost of this treatment process was found to be 3.60 US $/m3.

采用序贯化学混凝-连续流电氧化工艺处理屠宰厂废水
一家小型动物屠宰场(SWW)的废水采用两步法进行处理:混凝/絮凝(CF),然后是连续流电氧化(CFEO)。最初,CF 工艺中混凝剂的剂量为 0.8 公斤/立方米,在 pH 值为 8.5 时使用 FeCl3,COD 去除率为 52%,浊度去除率为 63%(出水:2000 毫克/升和 65.2 NTU)。明矾(最佳 pH = 6.5)的 COD 去除率为 50%,浊度去除率为 55%(出水为 2100 mg/L 和 78.5 NTU)。随后,在使用氯化铁的 CFEO 工艺之后,研究取得了高效的结果。具体而言,在最佳条件下(CFEO 反应器中的停留时间 τ = 240 分钟,反应器中的废水进料速率 = 15 mL/min,电流密度 = 300 A/m2 ),COD 和浊度去除率分别达到 99.60%(出水水质为 8 mg/L)和 99.9%(出水水质小于 0.10 NTU)。总之,CF + CFEO 连续处理工艺具有显著的处理效率,COD 和浊度去除率分别达到 99.9% 和 99.9%。此外,该处理工艺的总运行成本为 3.60 美元/立方米。
