Outline
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.
