摘　　要：针对嘉陵江梯级渠化利泽航运枢纽二期工程砂石加工系统设计用水规模与洗砂废水处理设备污水处理能力不匹配问题,采用“机械预处理+辐流沉淀池+压滤机脱水”模式处理砂石系统废水,实现了废水零排放及再利用,具有明显的环境社会效益。The designed water consumption of the sand and gravel processing system in Lize Shipping Hub project of the Jialing River cascade channelization second phase project does not match the wastewater treatment capacity of the sand washing wastewater treatment equipment.Thus,a comprehensive wastewater treatment scheme is proposed for the sand and gravel processing system,in which mechanical pre-treatment,radial flow sedimentation pool,and pressure filter dewatering are combined.It realizes zero wastewater discharge and wastewater reuse,with significant environmental and social benefits.
