| 摘 要： | 研究目的在于调查寒冷季节城市污水处理厂出水中天然有机物化学组分分级,探讨各分级组分与消毒副产物生成潜能间之关系。采集污水厂二级出水,以三种不同树脂把污水厂出水中有机物分离成六类不同组分,其中A水厂含量最高的物质为亲水酸性物质(33%)而B水厂的疏水性中性物质含量最多约占总有机物的64%。从总体来看两水厂的疏水性物质含量大于亲水性物质含量,疏水性物质的三卤甲烷生成势也较大,是水体中消毒副产物的主要前驱物质。疏水性有机物质较多,代表受生活污水污染严重,得知该城市污水主要受民生污染较多。

| Abstract: | The objective of the study was to investigate the relationship among distribution of natural organic matter (NOM),fractions and disinfection by-products formation potential from wastewater treatment plant in cold season. 6 species of NOM from secondary effluent were extracted by three kinds of resins,in which the highest content in Plant A was hydrophilic acid 33% while main organic matter in Plant B effluent was hydrophilic neutral (HPON)which has reached 65% of total DOC. From a general view of two wastew... |
