应用GC／MS联机检测技术对我国大陆和香港共11个城市污泥中4种醚类和4种卤代烃类化合物进行分析。结果表明，醚类化合物的总含量在0－7．743mg/kg之间，以双（2－氯异丙基）醚为主，主要分布在兰州污泥和广州污泥中；卤代烃类化合物的总含量在0．007－3．237mg/kg之间，以六氯环戊二烯为主，主要分布在兰州污泥、佛山污泥和沙田（香港）污泥中。污泥中醚类和卤代烃类化合物的种类及其含量与污水来源、污水处理方式、污泥类型、化合物的结构和理化性质等因素有关。     

Simultaneous sorption of aqueous phenanthrene and phosphate onto bentonites modified with AlCl3 and CTMAB

The purpose of this work is to synthesize a new type of bentonite sorbent that can simultaneously remove both organic compounds and phosphate from water. Inorganic-organic bentonites (Al-CTMAB-Bent) were synthesized by modifying bentonites with both AlCl₃ and cetyltrimethyl ammonium bromide (CTMAB). Simultaneous sorption of aqueous phenanthrene and phosphate onto Al-CTMAB-Bent was examined. Removal rates of phenanthrene and phosphate from water reached 96.3% and 90.2%, respectively, at their respective initial concentrations of 1 mg/L and 5 mg/L and the added amount of Al-CTMAB-Bent was 1.25 g/L. The residual turbidity of the Al-CTMAB-Bent suspension decreased 81.4% compared to that of organobentonite suspension after a 1 h settling time. Thus, inorganic-organic bentonite can be used to treat wastewater containing both organic pollutants and phosphate. Translated from Environmental Science, 2006, 27(1): 91–94 [译自: 环境科学]     

Pollution survey of carbonyl compounds in train air

The train is an important vehicle in China, but its air quality has important impacts on passengers’ health. In this work, pollution from carbonyl compounds was measured in the air of six trains. The objectives of this work were to investigate carbonyl compound levels in selected air from trains, identify their emission sources, and assess the intake of carbonyl compounds for passengers. The methods for sampling and analyzing 10 carbonyl compounds such as formaldehyde, acetaldehyde, acrolein, acetone, propionaldehyde, crotonaldehyde, butyraldehyde, benzaldehyde, cyclohexanone, and valeraldehyde in indoor air were proposed with the sampling efficiency, recovery, and detection limit being 92%–100%, 91%–104%, and 0.26–0.82 ng/m³, respectively. It was indicated that the total concentrations of carbonyl compounds were 0.159–0.2828 mg/m³ with the average concentration of 0.2330 mg/m³. The average concentrations of form aldehyde, acetaldehyde and acetone were 0.0922, 0.0499, and 0.0580 mg/m³, accounting for 42.6%, 21.4%, and 24.9% of the total concentrations of carbonyl compounds, respectively. The carbonyl compounds probably came from woodwork and cigarette smoking. The intake of carbonyl compounds for the passengers was approximately 0.043–0.076 mg/h. The carbonyl compounds in train air could be harmful to human health. Translated from Environmental Science, 2006, 27(1) 91–94 [译自: 环境科学]

典型北方高碱度微污染水体强化混凝的示范研究

以高碱度、受有机物污染的典型北方水体为例,探索适宜的强化混凝技术.在水质调查的基础上,提出适合水质特征的强化混凝目标.研究了高碱度水体强化混凝技术方法.研究表明,可以通过3条技术途径提高水体中有机物的去除效率.其一在混凝前优化pH,促进絮凝剂水解形成中聚体,AlCl3在pH 6左右,FeCl3在pH 5左右时,有机物去除率可以提高一倍左右;其二是强化沉淀软化;其三是絮凝剂优化.结合我国实际情况,通过对传统絮凝剂进行改性,研制出了适合我国北方水质特征的高效絮凝剂,能较传统絮凝剂将有机物去除率提高30%以上.
