交流电凝聚技术及其在油田污水处理方面的应用研究

交流电凝聚（ACE）技术能有效地从稳定的悬浮液和乳浊液中凝聚并分离出固相、重金属和油。电压缩和电絮凝促进凝结、快速沉淀及脱水，且不使用昂贵的高分子电解质和化学药品，也不需使用复杂且易于被超细微粒堵塞的过滤系统。木文介绍了ACE技术的初步原理及其在国外油田污水处理方面的应用，并与传统的污水净化方法进行了比较。     

DOMESTIC WASTEWATER TREATMENT BY PEATLANDS IN A NORTHERN CLIMATE: A WATER QUALITY STUDY1

ABSTRACT: The use of peatlands as the main form of wastewater treatment in a northern climate was studied for the James Bay Energy Society. The Fontanges campsite (70° 17′ 30″ W; 54° 34′ 00″ N) was chosen as the study site. In less than 1.5 km from the point of discharge BOD₅, COD, total hardness, inorganic carbon, orthophosphates, total phosphorus, ammonia and total nitrogen were reduced by at least 90 percent. The peatland treatment system studied is divided into four components, each having a specific function. The first part combines the action of microorganisms and adsorption on peat, thus reducing the organic content while increasing the inorganic constituents. The second part uses peat to adsorb the inorganic elements already present in the wastewater and those produced in the first part of the system. The third component acts as an aerator, increasing the dissolved oxygen and decreasing the BOD₅ levels of the water. The fourth part removes most of the remaining nutrients, thus acting like a tertiary treatment. Overall, peatlands seemed to be effective in treating domestic settled wastewater in a cold climate.

分级循环—生化法处理煤造气含氰废水

将含有大量悬浮物的洗气箱废水进行初级沉降后，约３／４的废水返回洗气箱用作洗涤水，其余的与洗气塔废水混合进地沉降池去除悬浮物，上清液送至生物滤池进行生化处理去除含氰人合物其他有机物。生化出水经絮凝、澄清后回用于洗气箱和洗气塔实现了废水闭路循环。他

Large-scale constructed wetlands for nutrient removal from stormwater runoff: An everglades restoration project

The South Florida Water Management District (SFWMD) constructed a wetland south of Lake Okeechobee to begin the process of removing nutrients (especially phosphorus) from agricultural stormwater runoff entering the Everglades. The project, called the Everglades Nutrient Removal (ENR) project, is a prototype for larger, similarly constructed wetlands that the SFWMD will build as part of the Everglades restoration program. This innovative project is believed to be one of the largest agricultural stormwater cleanup projects in the United States, if not in the world. This publication describes the ENR project's design, construction, and proposed operation, as well as the proposed research program to be implemented over the next few years.     

DESIGN BASIS FOR EVERGLADES STORMWATER TREATMENT AREAS1

ABSTRACT: The State of Florida (1994) has adopted a plan for addressing Everglades eutrophication problems by reducing anthropogenic phosphorus loads. The plan involves implementation of Best Management Practices in agricultural watersheds and construction of regional treatment marshes (Stormwater Treatment Areas or STA's). This paper describes the development, testing, and application of a mass-balance model for sizing STA's to achieve treatment objectives. The model is calibrated and tested against peat and water-column data collected in Water Conservation Area-2A (WCA-2A), where phosphorus dynamics and eutrophication impacts have been intensively studied. The 26-year-average rate of phosphorus accretion in peat is shown to be proportional to average water-column phosphorus concentration, with a proportionality constant of 10.2 m/yr (90 percent Confidence Interval = 8.9 to 11.6 m/yr). Spatial and temporal variations in marsh water-column data suggest that drought-induced recycling of phosphorus was important during periods of low stage in WCA-2A. Maintaining wet conditions will be important to promote phosphorus removal in STA's. Sensitivity analysis of STA performance is conducted over the range of uncertainty in model parameter estimates to assess the adequacy of the model as a basis for STA design.     

EC法处理选磷废水的研究

Refuse treatment options: a case study

Records in public archives were evaluated for the period 1981-1991. Simple surveys of peoples and of technology and physical premises provided insight to gauge the attitudes of a local community in the Melbourne municipality and the Melbourne City Council towards composting of organic waste materials. There is a lag in perception and attitudes between the local community and the local government towards composting of organic refuse as a solid waste treatment option. The simple methodology of the study still made it possible to verify past and present perceptions and attitudes.     

低温湿式空气氧化法处理废碱液的研究

对采用低温湿式空气氧化法处理炼油和乙烯废碱液进行了研究。考察了停留时间对废碱液中硫化物的氧化、氧化产物的形态、COD和酚去除率的影响，反应温度对废碱液中污染物氧化反应的影响。试验结果表明，废碱液的脱臭效果很好，S^2-的氧化产物以S2O3^2-和SO4^2-2种形式共存；酚、COD的去除率及S^2-的氧化反应停留时间影响小，受反应温度影响明显；废碱液的S^2-的酚浓度相当时，COD去除率一 般低于40％， 废碱液的S^2-浓度远大于酚浓度时，废碱液的COD去除率为40％－70％；废碱液中酚的质量浓度大于20000mg/L时才有回收价值。
