| 摘 要： | 目的]研究洗衣废水对河水水质的影响。方法]研究了绍兴市越城区4条河河埠头洗衣废水对河水总氮(TN)、总磷(TP)、悬浮物(SS)以及化学需氧量(COD)的影响。结果]洗衣废水排放瞬间河水COD及TN、TP、SS含量分别上升了507%、229%、148%、722%;随着时间的延长,4项指标含量均显著下降,尤其是洗衣废水排放60 min后,河水COD及TN、TP含量仅比洗衣废水排放前上升了50%、16%、44%,但河水SS含量仍然上升127%,需要更长时间的河水自净作用来去除。结论]洗衣废水排放对河水水质具有一定影响,而河水的自净作用可以有效去除污染物。

| Abstract: | Objective]To study the influence of laundry wastewater on river water quality.Method]Effects of laundry wastewater on the contents of total nitrogen (TN),total phosphorus (TP),suspended solids (SS) and chemical oxygen demand (COD) were studied in four rivers of Yuecheng District in Shaoxing City.Result]The results showed that the contents of TN,TP,SS and COD were increased by 229%,148%,722% and 507%,respectively,at the moment of laundry wastewater discharge.Four pollutional indexes were significantly decreased along with the time,especially 60 min after laundry wastewater discharge.Compared with that before laundry wastewater discharge,the contents of TN,TP and COD were increased by 16%,44% and 50%,respectively,but the contents of SS was still increased by 127% which require a longer time to achieve self-purification.Conclusion]Laundry wastewater has some influence on the river water quality,and the river self-purification function can effectively remove contaminants. |
