The integrated construction wastewater treatment equipment for horizontal pipes is composed of nine horizontal pipes ® The high-efficiency sedimentation tank, along with its associated sludge discharge, automatic flushing, automatic control system, dosing system, and pH adjustment system, can quickly separate high concentration inorganic suspension particles generated during the construction process. It can meet the water quality standards for miscellaneous water without the need for a filter tank and is used in various municipal facility construction scenarios, tunnel construction, and other construction processes that generate high turbidity, mud and sand containing wastewater.
