On Drinking Water Quality Condition and Characteristics of Phosphorus in Qianjiang District
To understand the source of drinking water in Qianjiang District (Xiaonanhai Reservoir ,Cheng-bei Reservoir and Dongtang Reservoir) of the water quality condition and distribution characteristics of phosphorus .The three drinking water resource of the region were studied from October of 2015 to Sep-tember of 2016 through monthly water quality monitoring .In total ,36 groups of valid data were obtained . The characteristics and pollution of phosphorus in drinking water were analyzed .The results show that to-tal phosphorus of three sources of drinking water met the surface water environment quality standard Ⅲ(GB3838－2002)(0 .05 mg/L) ,The dissolved phosphorus was the main phosphorus species in the three sources of drinking water ,soluble positive phosphate (DP) was the major form of soluble total phosphate (DTP) species in Xiaonanhai ,and dissolved organic phosphorus (DOP) was the major form of soluble total phosphate (DTP) species in Dongtang reservoir and Chengbei reservoir .The overall distribution of phos-phorus in three drinking water sources is :ρ(TP) ,Chengbei reservoir＞Dongtang reservoir＞Xiaonanhai ;ρ (DTP) ,Dongtang reservoir＞Xiaonanhai＞Chengbei reservoir ;ρ(DP) ,Dongtang reservoir＞Xiaonanhai＞Chengbei reservoir .Integrated pollution index showed that three sources of drinking water all belong to three levels of water quality ,and Water quality is light pollution .
