Résumé :
|
Constructed wetlands and, in some countries, modified natural wetlands are widely used for the treatment of different types of wastewater. Wetlands now have a record of good performance and reliability in applications that include sewage treatment for rural communities, farm effluents, urban and agricultural run-off, and sewage sludge dewatering. However there remains much work to be done in developing understanding of the mechanisms involved and clarifying the operational parameters and design methods that will optimise wetland performance. This challenge drew scientists, environmentalists and practitioners from around the world to Avignon to exchange their experience, scientific and engineering knowledge in order to promote the use of constructed wetlands as a sustainable technology for sewage and sludge treatment all over the world and with particular appeal in less economically developed countries where such techniques may be particularly appropriate to the physical and socio?economic conditions. Some of wetlands' key advantages ? high treatment efficiency with low energy consumption, low operation and maintenance costs are shared by waste stabilisation ponds and there is growing interest in the possibilities offered by combinations of stabilisation ponds and constructed wetlands. To enable sharing of information and insights IWA's 9th Wetland systems and 6th Waste Stabilisation Ponds (selected proceedings also to be published in Water Science and Technology) conferences were organised at the same venue and joint sessions were held. From the large, high?quality and wide?ranging programme of the Wetlands conference (including the joint sessions) these proceedings have been selected following peer review. They constitute an authoritative "state of the?art summary current research into the use of wetlands for water pollution control and their successful applications world-wide.
