Surfactants are widely used to improve the solubility of oil in water in petrochemical, making it more difficult to remove oil–water emulsions during the water treatment process. Electrocoagulation (EC) is an appropriate method for treating oily wastewater and destabilizing emulsions. However, the demulsification mechanism of oil–water droplets emulsified by surfactants with different charges have not been investigated systematically. The demulsification performance of electrocoagulation on emulsions wastewater containing cationic, non-ionic, and anionic surfactants was studied. The results showed that the removal rate of total organic carbon (TOC) in oily wastewater with anionic surfactant by EC reached 92.98% ± 0.40% at a current density of 1 mA/cm2, while that of the non-ionic surfactant was 84.88% ± 0.63%. The characterization of flocs showed that EC has the highest coagulation and demulsification of oil droplets with a negative charge on the surface (−70.50 ± 10.25 mV), which indicated that the charge neutralization of oil droplets was beneficial for the destabilization of the formed oily flocs. However, when the zeta potential of the oil droplets reached 75.50 ± 1.25 mV, the TOC removal efficiency was only 11.80% ± 1.43%. The TOC removal could achieve 33.23% ± 3.21% when the current density improved from 1 mA/cm2 to 10 mA/cm2. The enhanced removal was due to the sweep coagulation rather than charge neutralization. This study provides a fundamental basis for the electrochemical treatment of oily wastewater. 相似文献

Public participation in decision making is a central component of the planning process; however, implementing effective engagement initiatives to resolve complex planning and policy problems, such as climate change, is challenging for planners. These challenges are particularly acute in coastal communities throughout Australia, where many settlements are at risk of future climate perturbations. Using the International Association for Public Participation framework for public participation, we analyse three local government led public participation initiatives in New South Wales, Victoria and Tasmania, Australia. Our analysis suggests there are three critical factors that can influence the level of public participation in the context of climate change adaptation: the technocratic approach to decision making; absent high order government support; and the lack of evaluation mechanisms for public participation. 相似文献

The paper addresses the issue of how indemocratic societies a procedure might be formulatedto facilitate ethical judgements on modernbiotechnologies used in food production. A frameworkfor rational ethical analysis, the Ethical Matrix, isproposed. The Matrix adapts the principles describedby Beauchamp and Childress for application to medicalissues, to interest groups (e.g., producers,consumers, and the biotic environment) affected bythese technologies. The use of the Matrix isillustrated by applying it to an example of a ``novelfood,' viz., a form of genetically modified maize. 相似文献
