鉴于嘉陵江水文监测通常检测含沙量而不是悬浮物浓度值,而城市自来水厂排泥水系统干泥量是用“悬浮物/浑浊度”换算关系K1值进行计算,存在实际计算中只能用“含沙量/浑浊度”经验数据代替“悬浮物/浑浊度”但误差较大的问题,提出用“含沙量/浑浊度”代替“悬浮物/浑浊度”的适用性,以及通过试验确定“含沙量/浑浊度”的换算关系,有助于解决城市自来水厂排泥水系统设计中的这一难题。通过对嘉陵江广元段取样水体含沙量进行测定,推算“含沙量/浑浊度”的换算关系。试验结果表明：嘉陵江中段水环境在Ⅲ类水体条件内,可用含沙量与浑浊度之比Cs/TU代替悬浮物与浑浊度之比SS/TU,且含沙量与浑浊度曲线趋势线高度吻合；嘉陵江中段含沙量与浑浊度呈幂函数关系,当 Cs≤100 mg/L 时,TU =0．9773Cs0．856,100 mg/L <Cs≤1000 mg/L 时,TU =0．7435Cs0．909,Cs >1000 mg/L时,TU=0．5428Cs0．9526。

Jialing river hydrologic station usually detection sediment concentration rather than the suspension density. However, dry mud quantity calculation of sludge for exhausting sludge system of water plants adopts the conversion of“suspended solids/turbidi-ty”. This inconformity brings inconvenient and error to test the water quality. The applicability of “sediment / turbidity” instead of“suspended solids/turbidity” is investigated. In order to overcome the problems, as for the water in Guangyuan section of Jialing Riv-er, the conversion of“sediment / turbidity” is determined with experiments. The results of the experiments show that:the water quali-ty belongs to class Ⅲ, the ratio of sediment concentration and turbidity ( Cs/TU) can represent the ratio of suspended solids and tur-bidity ( SS/TU) , and the sediment concentration trend line highly matches with the turbidity curve trend line. There are power function relations between the water sediment concentration and turbidity, such as TU= 0. 9773 Cs0.856 if Cs≤100mg/L, TU=0. 7435Cs0.909 if 100 mg/L<Cs≤1 000 mg/L, and TU= 0. 5428Cs0.9526 if Cs >1000 mg/L.
