化学沉淀法除磷和生物法除磷的比较

对化学沉淀法除磷和生物法除磷的机理作了较详细的阐述，并就两者在除磷效果，污泥产量，污泥处置，除磷费用方面进行了比较。结果表明，两种方法磷的去除率比较接近，总费用没有明显差别，其优点是，生物法除磷污泥产量少，而化学沉淀法除磷操作简便。

An ecological economics approach to the management of a multi-purpose coastal wetland

Three interrelated management problems—eutrophication of multiple use shallow lakes, sea level rise and flood risk mitigation and tourism pressures—are analysed in the context of an internationally important wetland area, the Norfolk and Suffolk Broads in the UK. The ecological-economic research findings presented should provide essential information to underpin the regulatory and management process in this internationally important conservation area. The relevant authority somehow has to integrate the maintenance of public navigation rights, nature conservation, and tourism promotion in a highly dynamic ecosystems setting. Because of the stakeholder conflicts, potential and actual, a more inclusionary decision-making procedure is required, and is currently being implemented.     

Auditing a flooded quarry prior to marina development

Development of a marina in a flooded brownstone quarry will require construction of a canal to the Connecticut River through an isthmus separating the two systems. An environmental audit over a 16-month period developed quantitative limnological data required by regulatory agencies. The deep quarry basin, protected by high sandstone walls, became strongly stratified in summer. Development of littoral vegetation in the quarry was prevented by the steep sides of the basin. Unusual characteristics of the manmade quarry basin, compared to most natural lakes in Connecticut, included a mean depth of 14 m, an intense thermocline, and negative heterograde oxygen profiles with metalimnetic minima. Alkalinity, conductivity, and nutrient levels differed significantly between the quarry and the river. Mean chlorophyll a concentrations in the two systems were similar, but the distribution of phytoplankton classes were quite different. The environmental audit, by comparing physical, chemical, and biological characteristics of the quarry to those of the river, allowed prediction of changes in trophic status when the two systems are joined.

观音阁水库水体中氮、磷污染现状及其防治对策

本文通过对观音阁水库的水质进行监测和调查分析，了解观音阁水库水体中氮、磷污染状况及来源。根据监测和调查结果可以判断，磷是观音阁水库中限制性营养盐。通过采取必要的防治对策和措施，控制氮、磷的浓度，不仅可以控制观音阁水库水体富营养化程度，而且还能产生一定的经济效益。     

生物脱氮除磷工艺的研究进展

为遏制水体富营养化的恶化，氮，磷的排放标准日趋严格，生脱氮除磷工艺能有效地去除水体中的氮、磷。通过对现有的生物脱氮除磷传统工艺和新近发展工艺的介绍和分析，指出经济、高效、低能耗是其发展的方向，同时认为今后应加强对生物脱氮除磷机理更深入的研究，大力开发技术成熟，高效经济又符合我国国情的新工艺。     

Environmental impact of two successive chemical treatments in a small shallow eutrophied lake: Part I. Case of aluminium sulphate

This paper deals with the efficiency and effects of addition of aluminium sulphate on soft water quality of a shallow eutrophic lake. Almost all the controlled variables improved with treatment, especially nutrient concentrations such as soluble reactive phosphorus (SRP) and transparency. However, aluminium sulphate was not added in sufficient quantity to reduce the total phosphorus content. SRP concentration was significantly reduced in the short term. Moreover, external loading of phosphorus was high and not taken into account by the in-lake treatments. Finally, resuspension of sediment (polymictic lake) removed the alum hydroxide layer on the sediment surface, which reduced treatment effectiveness. No significant pH decrease was noted following alum addition. According to bibliographical toxicological data, monomeric aluminium content does not show any toxic effect on aquatic fauna and flora. In spite of low SRP in the water column, the treatment did not prevent appearance of Microcystis sp. colony (> 10 colony per ml) approximately 30 days after alum application.
