Abstract

The invention discloses an automatic treatment device for tunnel sewage. The device is provided with a chemical storage barrel for storing a PAC solution; an input type liquid level gauge is arrangedat a sewage discharge opening, the input type liquid level gauge is connected to a liquid level transmitter, and the liquid level transmitter is connected to an intelligent light beam measuring and controlling instrument; the intelligent light beam measuring and controlling instrument is further connected with an adjustable flow pump, the inlet end of the adjustable flow pump is connected with a chemical suction pipe placed in the chemical storage barrel, and the outlet end is connected with a chemical delivery pipe placed at the sewage discharge opening; and the sewage discharge opening, a three-stage sedimentation tank and a clean water discharge opening are connected in sequence. The device provided by the invention is safe and reliable, reduces energy consumption, saves construction costs, realizes automatic chemical adding, and realizes up-to-standard discharge of the tunnel sewage.

Description

technical field [0001] The invention relates to the field of tunnel sewage treatment equipment, in particular to an automatic treatment device for tunnel sewage. Background technique [0002] During the excavation process of the tunnel, construction wastewater and surrounding rock seepage will inevitably appear. The tunnel construction along the slope is generally discharged by gravity, and the tunnel on the reverse slope is discharged by pumping. Tunnel drainage is mainly the seepage of groundwater from the surrounding rocks in the tunnel. There are very few pollutants in the waste water, and most of them are underground seepage with excessive turbidity and suspended matter. Water seepage meets discharge standards. Water seepage in the cave during the period of blasting and slag discharge in the cave, due to the disturbance of construction machinery, suspended particles such as stone powder and silt in the water collection area of ​​the cave are stirred, and the turbidity ...
