The subject in this paper is the surface water of Yuecheng Reservoir in Handan. On the premise of analysing variation characteristics of sulphate of Yuecheng Reservoir, we recognized reasons of increased sulphate concentration value resulting in water pollution. It drew conclusions that sulphate concentration in Yuecheng Reservoir varied significantly during winter and reached maximum. At the same time, there was a significant correlation between sulphate concentration of atmospheric precipitation in urban areas and sulphate concentration of Yuecheng Reservoir, which was because that the sulphate of atmospheric precipitation reached to the reservoir by surface runoff, having a certain degree of influence on the sulphate concentration of Yuecheng Reservoir.Keywords

As a new type of high performance adsorbents and catalysts, activated carbon fibre (ACF) shows broad application prospects in flue gas desulfurization because of its unique physical and chemical properties. We designed a set of experiments to study the factors affecting desulfurization performance of ACF, namely determining desulfurization performance of ACF before and after its regeneration, ACF soaked with 100g lime and ACF soaked with the fly ash and lime whose ratio was 1:1. The results show that after ACF regeneration, desulfurization performance of ACF declines, and the duration is also reduced; after being soaked with 100g lime, desulfurization performance of ACF has been improved significantly, and the duration also increases; after being soaked with the fly ash and lime in the ratio of 1:1, desulfurization performance of ACF is higher than that soaked with 100g lime, and the duration is longer.Keywords
