The project was chosen as one of the six 2023 typical cases of industrial park water environment management by the Ministry of Ecology and Environment. It's the sole wastewater zero-discharge and crystallized salt resource utilization case. Adopting Jingyu Environment's self-developed, globally pioneering technology with a 4,000 m³/d treatment capacity. The processes include high-efficiency sedimentation, sand filtration, UF, resin, RO, pretreatment, impurity removal, NF salt separation, ozone catalytic oxidation, and MVR evaporation crystallization. All treated wastewater is recycled, yielding NaCl and Na₂SO₄ meeting national industrial salt standards, realizing resource recycling and bringing extra economic benefits to the park's development.
