Concrete wastewater treatment device and system

Abstract

Provided are concrete wastewater treatment device and system, pertaining to the field of concrete wastewater treatment. The concrete wastewater treatment device includes a first wall and a CO2 input pipe. The first wall encloses a first chamber, with the first wall being provided with a first liquid inlet and a first liquid outlet. The first liquid outlet is positioned higher than the first liquid inlet. The first chamber is equipped with a groove for accommodating reducing agent powder, which includes at least one of elemental iron, divalent iron compounds, and elemental aluminum. The CO2 input pipe is used to deliver CO2 into the first chamber, with the gas outlet end of the CO2 input pipe being close to or located within the groove. The gas outlet direction of the CO2 input pipe is configured such that the conveyed CO2 can induce turbulence and agitation in the reducing agent powder.
