  • 摘要: 针对太湖流域某复合污染型支浜阳台排放洗涤废水经雨水管道直接排河产生的污染问题，在雨水排放口上游设置溢流井，收集污水，提升至交替曝气生物滤池一体化设备，处理后排入河中，在工程稳定运行数月后，研究该技术处理效能、工艺优化方式和技术特色。综合评估表明：该处住宅阳台洗涤废水碳源浓度较低，但是即使C/N3·（m2·d）-13种水力负荷下氨氮容积负荷的变化均与氨氮去除率变化趋势一致；用normfit函数对3种水力负荷长期运行时氨氮出水浓度进行预测，结果表明平均出水浓度的区间估计均在0.79~2.18 mg·L-1较低浓度之间，且置信度均接近1，说明工程可在较大水力负荷下运行。周期内水质连续监测的结果表明，切换曝气方向后出水水质下降的延续时间为30 min，相应时段出水应进行回流处理。
    Abstract: The altering sequence biological filter (ASBF) technology was used to treat washing wastewater from residential balcony which had seriously polluted a river in Taihu Lake basin. After the project being steady, the treatment efficiency, the process optimization and technical characteristics were studied. The result shows that the COD influent concentration was very low, even though C/N was less than 1, the TN and TP removal rate could still reach 70% and 50%，respectively. The change of NH4+-N volume loading had a similar tendency with the change of NH4+-N removal rate under the hydraulic loads of 1.52, 1.90, 2.28 m3·(m2·d)-1. The normfit function was used to predict NH4+-N effluent concentrations during the long-term operation. Under the three hydraulic loads, the prediction shows that the average long-term NH4+-N effluent concentrations all were between 0.79 mg·L-1and 2.18 mg·L-1. Moreover, the confidence levels all were close to 1. It indicates that the project can operate under the maximum hydraulic load. According to the result of water quality in one cycle, the duration of water quality deterioration was 30 minutes after switching the aeration direction, and the effluent of corresponding period should be retreated.
