Abstract: Here, taking the river flowing through Huancheng Park as the treatment object, composite flocculant was used for the treatment of slightly polluted water. Overall, total phosphorus (TP), ammonia nitrogen (NH₃-N), algae, and algal were removed by 85, 60, 99, and 50%, respectively. Water transparency increased from 35 to 100 cm, and turbidity and chromaticity were significantly improved. No secondary pollution was observed, and kept the ecological nature of water. Combined with engineering examples, the principle and characteristics of ecological compound flocculant water purification were analysed, and the feasibility of this method in the treatment of natural open micro-polluted water was verified. This study provides a scientific basis for the use of composite flocculant in the treatment of micro-polluted waterbodies in urban areas.

Keywords: open waterbody; micro-pollution; flocculant; treatment process.
