| 摘 要： | 研究了氧化偶合絮凝法处理城市污水的性能及污水中有机污染物的性质,并通过色谱-质谱对原污水、混凝沉降后水、氧化偶合絮凝处理后水中的可分析有机物进行了定性、定量分析,探讨了氧化偶合絮凝法处理城市污水中有机物的机理.结果表明,一般化学混凝沉降只是通过絮凝吸附作用去除污水中有机物,有机污染物总量和种类均降低很少;氧化偶合絮凝法通过催化氧化协同絮凝吸附,不仅使污水中有机物的总量大大降低,同时也使有机物种类大大减少.

| Abstract: | The removal efficiency of organic substances in municipal wastewater using the oxidation-flocculation treatment technique was studied.The organic substances in the raw wastewater and the outlet water treated by the coagulation subsidence and oxidation-flocculation methods were analyzed,respectively by gas chromatography-mass spectrometry(GC-MS).The mechanism of the oxidation-flocculation treatment technique was proposed in detail and clarified.The results have shown that the classical coagulation subsidence plays only the adsorption role in wastewater treatment and is difficult to remove organic substances.However,the oxidation-flocculation technique as the combination of both the coagulation sorption and the catalytic oxidation can degrade most of various organic substances and the removal efficiency increased notably. |
