With the escalation of Lake Eutrophication,and the frequency of algal bloom outbreaks is getting higher and higher,which is becoming a major environmental bottlenecks in restricting social and economic sustainable development in China.It is urgent to carry out studies on lake nutrient criteria and develop ecoregion nutrient criteria fitted to China s regional characteristics,as theoretic basis for lake eutrophication prevention,control and management.The wide survey should be firstly carried out to get a deep judge of Chinas lake eutrophication problems and their regional differences.Then,nutrient ecological regions,which are the basic units for the eutrophication standards,need to be determined.Furthermore,nutrient criteria should be developed for each ecoregion,to form the scientific basis of the.development of eutrophication standards.Based on ecoregion nutrient criteria,according to different ecoregional nutrients load,different trophic state of lakes and different geographic features,the eutrophication control standard and national lake eutrophication control strategy should be established to direct nutrient total mass control and reduce nutrient load of ecoregion lakes.

研究建立交接断面排污总量财政结算机制：1、以上级政府确定的断面功能区划的水质标准和该断面多年平均迳流量确定该断面允许的排污总量。2、对该断面水质和流量进行自动或人工监测，测定当年排污总量。3、按照国家排污收费单价，国家未明确的按省物价局确定的单价计算金额。当上游超总量指标排放污染物时，由上一级政府在年终财政结算中从上游地方财政向下游支付超指标部分的污染物排放责任金；当上游少于总量指标排放时，由下游
仙女湖是重要旅游景区和城市主要饮用水源地，本文分析了影响仙女湖水环境的诸多因素和成因。论述了加强仙女湖水环境综合整治的必要性；并从管理机制、政策导向、资金投入模式以及防治工作企业废水、农村面源污染、景区生活污水、网箱养鱼、游船废水等方面提出了相应对策，为打造仙女湖现代休闲度假中心提供环境保护依据。
研究了孔石莼(Ulva pertusa)对Cu(Ⅱ)、Zn(Ⅱ)的吸附动力学,从Cu(Ⅱ)、Zn(Ⅱ)的初始浓度、温度及Cu(Ⅱ)、Zn(Ⅱ)共存等方面探讨影响吸附速率及吸附容量的因素。采用准一级动力学和准二级动力学方程描述了吸附过程的动力学特性。结果表明,准二级动力学方程能较好地拟合孔石莼吸附Cu(Ⅱ)的实验数据(拟合优度r2＞0.99)。平衡吸附量qe随初始浓度增加而增大,准二级动力学速率常数
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

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。
