The water quality of Hengshui Lake in different regions and at different times was analyzed. According to the data analysis results of chemical oxygen demand (COD), biochemical oxygen demand (BOD5), ammonia nitrogen (NH3-N), total nitrogen (TN), total organic carbon (TOC), total phosphorus (TP), calcium ion content, total hardness, chloride ion content, pH value and conductivity of Hengshui Lake water samples, the water quality of Hengshui Lake was evaluated and analyzed. The results showed that the pollution of Hengshui Lake was mainly organic matter pollution, especially non-biodegradable organic matter pollution. The value of TN was higher than the Class III water, which showed that the self purification capacity of Hengshui Lake water body was weaker. The water quality of Hengshui Lake was better, but the treatment of organic pollution should be paid attention to.
