Design of Advanced Treatment Scheme for Reclaimed Water of a H-class Gas Turbine Power Plant

Abstract

[Introduction] In order to fully implement the national policies on water resource development and utilization, embody the water-saving policies on water resource reuse, more and more industrial water source supplied to power plants in south China is reclaimed water, so it is necessary to discuss the schematic design of advanced treatment for reclaimed water. [Method] Taking a power plant in Guangdong province as an example, this paper designed the most suitable advanced treatment for reclaimed water by analyzing the treatment process of wastewater treatment plant, water quality indicators of reclaimed water and industrial water quality requirements of power plant. [Result] Adopting the scheme of "contact flocculation inclined plate sedimentation tank + filter tank", the system process was simple, the investment and operation cost were low, and the system can guarantee the safe and reliable operation. [Conclusion] This paper aimed to provide a reference scheme for the advanced treatment system design of reclaimed water in similar water source power plants in the future.
