European cropping systems are often characterized by short rotations or even monocropping,leading to environmental issues such as soil degradation,water eutrophication,and air pollution including greenhouse gas emissions,that contribute to climate change and biodiversity *** use of diversification practices(i.e.,intercropping,multiple cropping including cover cropping and rotation extension),may help enhance agrobiodiversity and deliver ecosystem services while developing new value *** its benefits,crop diversification is hindered by various technical,organizational,and institutional barriers along value chains(input industries,farms,trading and processing industries,retailers,and consumers)and within sociotechnical systems(policy,research,education,regulation and advisory).Six EU-funded research projects have joined forces to boost crop diversification by creating the European Crop Diversification Cluster(CDC).This Cluster aggregates research,innovation,commercial and citizen-focused partnerships to identify and remove barriers across the agrifood system and thus enables the uptake of diversification measures by all European value-chain *** CDC will produce a typology of barriers,develop tools to accompany actors in their transition,harmonize the use of multicriteria assessment indicators,prepare policy recommendations and pave the way for a long-term network on crop diversification.

Photocatalytic degradation of dye effluent by titanium dioxide pillar pellets in aqueous solution

引用

Journal of Environmental Sciences 2004年第3期16卷 375-379页

作者： eric Hu School of Engineering and Technology

Photocatalytic oxidation(PCO) process is an effective way to deal with organic pollutants in wastewater which could be difficult to be degraded by conventional biological treatment methods. Normally the TiO 2 powder in nanometre size range was directly used as photocatalyst for dye degradation in wastewater. However the titanium dioxide powder was arduous to be recovered from the solution after treatment. In this application, a new form of TiO 2(i. e. pillar pellets ranging from 2 5 to 5 3 mm long and with a diameter of 3 7 mm) was used and investigated for photocatalytic degradation of textile dye effluent. A test system was built with a flat plate reactor(FPR) and UV light source(blacklight and solar simulator as light source respectively) for investigating the effectiveness of the new form of TiO 2. It was found that the photocatalytic process under this configuration could efficiently remove colours from textile dyeing effluent. Comparing with the TiO 2 powder, the pellet was very easy to recovered from the treated solution and can be reused in multiple times without the significant change on the photocatalytic property. The results also showed that to achieve the same photocatalytic performance, the FPR area by pellets was about 91% smaller than required by TiO 2 powder. At least TiO 2 pellet could be used as an alternative form of photocatalyst in applications for textile effluent treatment process, also other wastewater treatment processes.
