城市雨水径流控制与利用

随着经济的发展,人们生活水平的提高,城市化进程的加快,使得城区道路的硬化面积不断增加,导致雨水不能被植物截留下渗涵养地下水,只能在路面形成汇流。汇流的雨水增加,径流系数增大,形成了地面的雨水径流。径流的污染情况比较严重,当径流量超过排水管网的最大负荷时就会形成内涝灾害。城市雨水的污染主要是非点源污染,因此,初期雨水径流如果直接排放到河流水体当中会造成污染,所以应加强对城市雨水控制与利用的研究。

Colonization of periodically inundated interstitial habitats of an alluvial pond by invertebrates

The interstitial fauna of an alluvial pond on the floodplain of the Adour River, South-west France was sampled over a period of 13 months. The pond was connected to the adjacent river through phreatic flow and its water level varied in an annual cycle related to the level of the river. Monthly samples were taken from fixed points along five transects across the pond. The littoral zone was sampled between +20 and ?80 cm from the substrate surface. From the seasonal variations in the distribution and abundance of invertebrates, the dynamics of their colonization and decolonization cycles could be elucidated and related to the variations in the groundwater level. Eight different colonization/decolonization cycles were determined, each one being characterized by a ‘typical’ common species. These included both passive and active movements in response to the changes in water level. Many taxa were shown to have behavioural strategies which altered according to the stages of their life cycles. Most aquatic invertebrates were adapted to move into the most stable conditions at a given time of the year. Certain terrestial species were also shown to tolerate short periods of immersion.     

Promoting sustainable sanitation through wastewater-fed aquaculture: a case study from Ghana

Several of the 10 key challenges targeted by the African Water Vision 2025 are directly or indirectly related to human waste management, in particular strengthening the financial base for providing adequate sanitation services. This case study describes a novel approach to improving the operation and maintenance of a waste stabilization pond system in Ghana by turning it into a dual-purpose wastewater treatment plant and commercial fish farm. Results of a collaborative pilot study between private, public and academic partners to test the institutional and technical feasibility of the model as well as the public health impacts are presented.
