针对采油废水中含有多环芳烃种类多且较难去除的特点,采用UV-Fenton技术对采油废水中多环芳烃的处理效果进行了研究,通过正交实验和单因素实验,研究了在254 nm波长紫外光照射下,Fe2+投加量、H2O2投加量、pH值和光照时间对水样中多环芳烃中的菲和芴处理效果的影响。实验结果显示,处理初始浓度为1 000 μg/L的菲、芴时,反应的最佳工艺条件为:Fe2+浓度为1.8 mmol/L、H2O2投...
UV-B irradiance can be estimated from surface meteorological data or from satellite measurements. This paper compares irradiance estimates from the Davies surface-based radiation model and the Canada ...
Stratospheric ozone depletion, as a result of increasing chlorofluorocarbons in the stratosphere, allows more UV-B irradiance (290 - 325 nm) to reach the earth’s surface with possible detrimental biol...
The solar UV radiation has prominent impacts on human life, animals and plants with positive and negative effects. Atmospheric ozone, which is formed from the photodissociation of molecular oxygen mai...
Time series of daily UV radiation measured by the ground-based Brewer spectrophotometer #115 in Hong Kong during 1995-2005 were studied through statistics analysis, with focus on the variability and l...
采用UV-Fenton体系预处理四氢呋喃废水,实验结果表明,pH值、反应时间、Fe2+和H2O2投加量等因素对处理效果有较大的影响。实验确定的最佳反应条件为:原水pH=5,Fe2+投加量2.5 mmol/L,H2O2投加量12 mmol/L,反应时间90 min,连续曝气,在此条件下,COD去除率可达85%左右。经UV-Fenton体系处理后,废水的B/C值由0.16增至0.47,可生化性提高,可...
Immobilization of cadmium (10 mg Cd per kilogram soil) in soil by bioaugmentation of a UV-mutatedmicroorganism,Bacillus subtilis38 accompanied with amendment of a bio-fertilizer, NovoGro was inves-tig...
Continuous mercury monitors (CMMs) have the advantage of performing real-time or near real-time measurement, although they are often vulnerable to measurement interferences. For example, CMMs based ...
