Effect of Tail-Water of Water Source Heat Pumps on Lake Phytoplankton

Abstract:

Taking water heat pump project in Kaixian Peoples Hospital of Chongqing City as a research example, by long-term monitoring on the lake temperature, nitrogen, phosphorus, and population distribution of algae, the effect of tail-water on phytoplankton of lake was studied. The results show that the tail-water have some influences on the number and diversity of algae in summer when the lake water heat pump system works, and the total number of algae near the tail-water discharge point is lower than that in other regions, but the dominant algae in different sampling points are same at the same time. In winter, cold water discharge makes the total number of algae near the tail-water discharge point essentially higher than that in other regions. Moreover, cold discharge water can reduce the diversity index of the lake phytoplankton. In addition, tail-water has a seasonal influence on lake phytoplankton, and its cumulative environmental impact can be obtained through monitoring and comparative research by long-term.
