Effect of Residual Chlorine on Marine Organisms for Huarun Caofeidian Power Plant

Abstract

Abstract. Aiming at influence of discharge thermal water from the Huarun Caofeidian power plant, a 2D hydrodynamic model was used to simulate the tidal current field of waters receiving residual chlorine in discharged thermal water in Caofeidian Coastal Area. With the computed tidal current field considered to be the hydrodynamic conditions of the residual chlorine transport simulation, the concentration distribution of the residual chlorine was predicted with a 2D convection diffusion model and its effect on the marine organisms was analyzed. The results show that, the area affected by residual chlorine water is 0.14 and 0.21km 2 respectively in winter and summer. The residual chlorine concentration around the outfall is lower than most of the safety concentration for shellfish and Copepods. In winter and summer, some fish avoided reaction to the residual chlorine which area is 0.83 and 1.43km 2 respectively.

Investigating Residual Chlorine in Water Streams at Low Flow Conditions Using 2d Water Quality Model

“…To study the most extreme case, the area was studied during the closure in the winter season. The kinematics during this season has Lake Regime characteristics; the velocities are relatively low which causes a high concentration of any discharge effluent spatially and temporally [4].…”

“…Increasing the concentration of residual chlorine may affect the water quality of the ambient water and hence, the ecological system [2]. When the cooling water containing chlorine discharged into nearby waters, it will affect the ecological environment of water [3].It is important to study residual chlorine from cooling water of power plants as it might cause severe effects on the environment as previously studied [4], [5]and [6].…”
