Jiangxi Fengcheng coal-fired power plant is equipped with 2*700MW generating units. The desulfurization process adopts the limestone-gypsum method. The desulfurization wastewater generated by the system is directly introduced into the slag water system of the slag scooper without treatment. Due to equipment corrosion and environmental protection pressure, the power plant is planned to be built. A desulfurization wastewater treatment system. As a leader in integrated desulfurization wastewater treatment technology, Beijing Huade Chuangye Environmental Protection Equipment Co., Ltd. undertook the new desulfurization wastewater treatment system project of the plant, using HDCY integrated treatment devices, and provided services such as equipment supply, on-site construction, installation, and commissioning. The project successfully passed the 168-hour trial operation quality acceptance on April 12, 2019.
