在小试和中试试验的基础上,研制了一套水力空化联合臭氧灭藻及净化富营养化水体的工业化水处理系统。在工程运行中,比较了优化条件下复合空化-臭氧、正压空化-臭氧、抽吸空化-臭氧和单独臭氧氧化工艺以及孔板孔径对水体中叶绿素a、浊度...在小试和中试试验的基础上,研制了一套水力空化联合臭氧灭藻及净化富营养化水体的工业化水处理系统。在工程运行中,比较了优化条件下复合空化-臭氧、正压空化-臭氧、抽吸空化-臭氧和单独臭氧氧化工艺以及孔板孔径对水体中叶绿素a、浊度、UV254、COD以及氨氮等的处理效果。同时,还对复合空化-臭氧和单独臭氧氧化工艺的臭氧利用率、臭氧和单位能耗的净化效率等经济技术指标进行了比较。结果表明,采用复合空化-臭氧工艺在10或5 m3·h-1处理能力下稳定出水期叶绿素a平均去除率分别达44.5%和88.9%,单位能耗分别为0.89和1.78 k W·h·m-3。同时,浊度、UV254及COD等指标均明显下降,其他各项经济技术指标也均显著优于单独臭氧氧化工艺。因此,利用水力空化-臭氧工艺能快速有效灭藻并去除叶绿素,遏制水华产生,减少因水华爆发及藻死亡引起的生态破坏和经济损失。展开更多
An uncatalyzed and easily accessible synthetic approach for the preparation of 3-aroylindoles was investigated using nitrosoarenes and aromatic terminal ethynyl ketones. Indole derivatives were produced in good yields...An uncatalyzed and easily accessible synthetic approach for the preparation of 3-aroylindoles was investigated using nitrosoarenes and aromatic terminal ethynyl ketones. Indole derivatives were produced in good yields and excellent regioselectivity. Functionalizations of the indole products were carried out affording highly valuable and versatile compounds. The indolization protocol was studied as a fundamental step for the preparation of pravadoline and 1-butyl-3-(1-naphthoyl)indole (JWH-073), bioactive molecules showing antinociceptic properties.展开更多
