【摘要】：隨著社會經(jīng)濟的高速發(fā)展,黃浦江下游段水源污染日益加劇,嚴重威脅飲用水安全。上海某水廠采用常規(guī)工藝處理該水源已難以滿足國家水質(zhì)標準的變化,由此消毒過程中THMs、HAAs等DBPs超標的現(xiàn)象時有發(fā)生。因此有必要研究和引入深度處理技術來獲得優(yōu)質(zhì)飲用水。本文對黃浦江下游段水源及中試砂濾出水水質(zhì)進行了綜合評價,系統(tǒng)研究了O3-BAC及O3/H2O2-BAC兩種組合工藝對砂濾出水的處理效果,得出以下結論： 2010年下半年度原水DOC月平均值為4.90-531mg/L。由于傳統(tǒng)前處理工藝對DBPs前驅物的去除能力有限,致使濾后水DBPFP濃度范圍高達250-330μg/L；通過連續(xù)半年的中試試驗發(fā)現(xiàn)臭氧組合工藝對于濾后水中有機污染物及DBPs前驅物去除效果良好。其中03=2.0mg/L為O3-BAC工藝的最佳試驗條件,炭后出水中DOC、UV254、THMFP及HAA5FP去除率分別為41%、64%、36%和47%；而O3/H2O2-BAC工藝在提升DBPFP去除率的同時又對溴酸生成量進行了有效控制,反應出水中溴酸濃度基本維持在1-2μg/L左右。其中O3=2.0mg/L, H2O2/O3=0.5為該工藝最佳試驗條件,炭后出水中DOC、UV254、THMFP及HAA5FP去除率分別為52%、70%、51%和55%。 根據(jù)中試試驗結果,O3/H2O2-BAC工藝的處理效果整體優(yōu)于O3-BAC工藝,并最終確定O3=2.0mg/L, H2O2/O3=0.5為臭氧組合工藝對黃浦江下游水源深度處理的最佳工藝條件。
[Abstract]:With the rapid development of social economy, the pollution of water in the lower reaches of Huangpu River is becoming more and more serious, which seriously threatens the safety of drinking water. It is difficult to meet the change of national water quality standard by using conventional process to treat the water source in a water works in Shanghai. Thus, the phenomenon of DBPs exceeding the standard such as THMsHas and so on occurs frequently in the process of disinfection. Therefore, it is necessary to study and introduce advanced treatment technology to obtain high quality drinking water. In this paper, the comprehensive evaluation of the water source and the effluent quality of the pilot sand filter in the lower reaches of Huangpu River is carried out, and the treatment effect of the two combined processes of O3-BAC and O3/H2O2-BAC on the sand filtration water is studied systematically. The results are as follows: the average monthly DOC of raw water in the second half of 2010 is 4.90-531 mg / L. Because of the limited removal ability of DBPs precursor by the traditional pretreatment process, the concentration range of DBPFP in filtered water is as high as 250 ~ 330 渭 g / L; It was found that the combined ozone process had a good effect on removing organic pollutants and DBPs precursors in filtered water. 03=2.0mg/L is the best test condition for O3-BAC process, and the removal rates of HAA5FP and DOC UV254THMFP are 41% and 47%, respectively, while O3/H2O2-BAC process can effectively control the amount of bromate while increasing the removal rate of DBPFP. The concentration of bromic acid in water was about 1-2 渭 g / L. Among them, 2.0 mg / L of O _ 3N, H2O2/O3=0.5 is the best test condition. The removal rates of H2O2/O3=0.5 and HAA5FP are 52.1% and 55.1%, respectively. According to the results of pilot test, the treatment effect of O _ 3 / H _ 2O _ 2-BAC process is better than that of O3-BAC process. Finally, it is determined that O _ 3N _ 2O _ 2 mg / L and H2O2/O3=0.5 are the best process conditions for advanced treatment of water source in the lower reaches of Huangpu River by ozone combination process.
