EXCAVATION WASTEWATER TREATMENT APPARATUS AND METHOD HAVING HIGH-EFFICIENCY ADMIXTUREFLOC SEDIMENTATION EQUIPMENT

摘要

The present invention provides an excavation wastewater treatment apparatus, which comprises: an inclined plate type grit tank having a settling chamber having a plurality of inclined plates installed thereon to remove particulate matter from the excavation wastewater; a flow rate adjustment tank for adjusting the flow rate uniformly by reducing the water quality load caused by the fluctuation of the flow rate of the excavation wastewater; a pipe reactor in which a chemical is introduced into a fluid to be coagulated and mixed, thereby allowing stabilization and enlarging of floc formed; an inclined plate type settling tank having a settling chamber in which a plurality of inclined plates are installed for depositing fine particles formed in the pipe reactor; and a treatment tank filter for storing the supernatant of the settling tank, adjusting the final pH, and then transferring the supernatant to the next process, and treating the fine particulate matter remaining after chemical precipitation.;COPYRIGHT KIPO 2020
