The concentration of total nitrogen (TN) is reported to vary between 20 and 35 mg/L in domestic wastewater. In raw wastewater, ammonia nitrogen eNHt4-NT is the
Flow characteristics of thermally stratified shear flow in braided rivers are particularly complicated and poorly understood. In this study, a series of typical
Experimental and theoretical studies were carried out to investigate the coupled influence of flow velocity increment and particle size on the retention and rel
