EPC project for zero discharge of desulfurization wastewater in the expansion of 2 × 660MW cogeneration in the second phase of the CHN ENERGY Harbin Thermal Power Company

The Phase II expansion project of Guoneng Harbin Thermal Power Co., Ltd., as the first batch of 'two joint ventures' demonstration projects in China, is a key project in Heilongjiang Province and an annual key project of the National Energy Group. The project plans to construct two 660MW ultra supercritical cogeneration units, which are scheduled to be put into operation in 2026. After completion, it will become the largest urban supporting main heat source in Heilongjiang Province, effectively filling the future power gap of the Heilongjiang power grid. It has significant and far-reaching significance for optimizing the energy structure of Heilongjiang Province and ensuring the safety and reliability of power supply in Heilongjiang Province. As a supporting environmental protection project, the zero discharge system for desulfurization wastewater is a key link in achieving green and low-carbon operation of the project, and is a key technology for the thermal power industry to achieve 'near zero pollution'.

This project adopts a mature and reliable low-temperature multi effect flash evaporation concentration+bypass flue evaporation process to efficiently separate and resource utilize impurities in wastewater, significantly reducing environmental load and helping Harbin Thermal Power Company build a benchmark for 'clean thermal power'.
