Jingyu Environment has taken on the Concentrated Brine Zero-Discharge Project in Phase II of Dongming Jieyuan Sewage Treatment Plant. With a designed sewage treatment capacity of 60,000 tons daily, it passed acceptance in July 2023 and got a "High-Quality Project Commendation Letter" from the owner. The project uses pretreatment, biochemical and advanced treatment processes to handle diverse sewage in Dongming Petrochemical Industrial Park, meeting discharge standards and enabling reclaimed water reuse. It can receive domestic, saline, oily, high-concentration, and alkaline residue sewage, etc. Achieving "separate collection, one-pipe-per-enterprise, above-ground piping, differential treatment and reuse", it eases the operation pressure of Jieyuan's existing sewage device, boosts the infrastructure service level of Dongming Petrochemical Park, resolves sewage discharge issues, and safeguards the park's water ecological health.
