摘　　要：针对暴雨、台风天气下桩基集中施工或基坑大面积开挖等情况,提出一种施工污泥废水净化处理循环利用技术,利用一体化净化处理装置,形成集沉淀、净化和循环利用于一体的污泥废水处理系统。采用絮凝剂、聚丙烯酰胺、聚合氯化铝与三级沉淀后的污水进行混合、搅拌、反应,使污水固液分离成泥浆和清水。清水可循环用于现场施工、洗车、洒水降尘等,达到绿色经济、高效环保的效果,大幅提升现场文明施工形象,取得了显著的效益。In view of the centralized construction of pile foundation or large-scale excavation of foundation pit in rainstorm and typhoon weather,a technology for purification,treatment and recycling of construction sludge and wastewater is proposed.An integrated purification treatment device was used to form a sludge and wastewater treatment system that integrates sedimentation,purification and recycling.Flocculants,polyacrylamide,polyaluminum chloride were used to mix,mix and react with the sewage after three-stage sedimentation,so that the sewage solid-liquid can be separated into mud and clean water.Clear water can be recycled for on-site construction,car washing,watering and dust reduction,etc.,achieving the effect of green economy,high efficiency and environmental protection,greatly improving the image of on-site civilized construction,and obtaining significant benefits.
