摘要

本研究旨在发现初始浓度和水力停留时间（HRT）对改良化粪池（MST）处理办公楼废水性能的影响。所使用的合成废水的平均 COD:TN:TP 比率为 84:28:1，并根据办公楼废水的特点进行了调整。实验在稳定条件下进行，使用了三种不同的 HRT（12、24 和 36 小时）和不同的 COD（106、252 和 432 毫克 COD/L）、TN（35、85 和 146 毫克 N/L）和 TP（1.26、3 和 5.14 毫克 P/L）初始浓度。结果表明，MST 可去除 82% 至 92% 的 COD、41% 至 60% 的 TN、45% 至 61% 的 NH4 和 39% 至 55% 的 TP。最大去除率出现在 36 小时的 HRT、COD:TN（3:1）和 COD:TP（84:1）条件下。单因子方差分析显示，初始浓度和 HRT 对 MST 的性能有显著影响（p < 0.05）。这表明，适当控制 MST 的初始浓度和 HRT 可以有效去除办公楼废水中的有机物和营养物质。

Performance of Moving Bed Biofilm Reactor Integrated Septic Tank in Treating Office Building Wastewater

This research aimed to find the effect of initial concentration and hydraulic retention time (HRT) on modified septic tank (MST) performance in treating wastewater from an office building. The synthetic wastewater used had an average COD:TN:TP ratio of 84:28:1, adjusted to office building wastewater characteristics. The experiment was executed under steady conditions using three variations of HRT (12, 24, and 36 hours) and different initial concentrations of COD (106, 252 and 432 mg COD/L), TN (35, 85 and 146 mg N/L) and TP (1.26, 3 and 5.14 mg P/L). The result showed that the MST removed 82% to 92% of COD, 41% to 60% of TN, 45% to 61% of NH4, and 39% to 55% of TP. The maximum removal was achieved at 36 h of HRT, COD:TN (3:1), and COD:TP (84:1). One-way ANOVA showed that the initial concentration and HRT had significant effects on the performance of MST (p < 0.05). This suggests that appropriate control of the initial concentration and HRT in the MST can effectively remove organics and nutrients from office building wastewater.
