Sludge accumulation in stabilisation ponds in the Soudano–Sahelian climate of Burkina Faso

摘要: ABSTRACT Sludge accumulation in waste stabilisation ponds based on local conditions is of great interest for successful sludge management, and accurate data are essential WSP design reasonable model development relation to the effect climate variability. For this purpose, a series three treating domestic wastewater Soudano–Sahelian Burkina Faso were monitored accumulation. After five half years operation, rates evaluated at 0.019, 0.009 0.007 m3 per capita year, respectively, anaerobic (AP), facultative (FP) maturation pond (MP). The corresponding dry weight (dw) person year calculated 1.3, 0.43 0.26 kg dw AP, FP MP. A coefficient high biodegradability was found AP. In contrast seasonal evolution reported Mediterranea...
