Mineralization process of organic phosphorus in sediment was important to phosphorus releasing in some lakes.Phytate- P was the main form of organic phosphorus in all lake sediments studied so far.The methods for extracting and exterminating phytate from sediment had been studied.LC - MS will be a useful method after appropriate pre - purification on sediments.

臭氧-双氧水联用预处理高浓度制药废水
本文针对制药废水高COD高盐量的特点,采用臭氧-双氧水联用技术对其进行预处理,提高其可生化性,便于实现后续生物处理。臭氧作为一种强氧化剂,可氧化难降解有机物,H2O2在溶液中分解的中间体可促进反应形成较多的·OH自由基,产生的协同作用可进一步强化O3的氧化能力。本实验通过臭氧-双氧水联用技术预处理高浓度制药废水,研究了反应时间、pH值、O3用量、H2O2投加量对废水COD去除率的影响,结果表明：当

青海湖流域入湖河流水质变化及其原因分析
水质作为流域生态系统的重要指标，受到包括地质、气候、植被、人类活动等多单项种因素的影响，是由多种自然及人为因素相互作用与影响的结果。应用形象分级法对青海湖入湖河流水质进行单项污染指数及综合评价，结果显示，综合评价指数均符合Ⅰ类标准，水质状况较好，且年际变化不明显。单项评价指数表明，河流污染的主要污染因子为总氮。文章认为总氮超标的主要原因是以畜牧业为主的面源污染和自然因素所致。
