The 25th National \"Safety Production Month\" in 2026: Everyone talks about safety, and everyone knows how to handle emergencies; identifying and addressing risks and hazards -------------------------------------------------- I. Project Overview 1. Basic project information Full name of the project: Construction of a facility for the comprehensive treatment of 3 million tons per year of high-organic-content saline wastewater and 50,000 tons per year of waste salt in Cangzhou Lingang Economic and Technological Development Zone Contractor: Hebei Zhongjian Resource Recycling Co., Ltd. Location: Cangzhou Lingang Chemical Industry Park, Huanghua City, Cangzhou Province, northeast of the intersection of Tongyi Road and Huagong Third Road Approval document number: Canggang Jingbei Zi [2025] No. 56. It is one of the key provincial construction projects in Hebei Province for 2026. Total investment: 1.528 billion yuan, with the funds coming from the company itself； The project will be implemented in phases one and two, with an investment of 601 million yuan for phase one. Construction period: The overall plan is for 2026–2027, with the first phase taking a total of 500 calendar days (140 days for design + 360 days for construction). 2. Construction scale – Total scale: Annual treatment capacity of 3 million tons of high-organic-content saline wastewater and 50,000 tons of waste salt, with an annual output of 9 million tons of reclaimed water ； - Phase 1: Capable of treating 600,000 tons of wastewater with high organic salt content and 40,000 tons of waste salts per year, along with supporting recycled water reuse ； - The main buildings and structures include a comprehensive building, a R&D and quality inspection center, a wet oxidation workshop, a high-temperature oxidation workshop for waste salts, a membrane treatment workshop, an evaporation and crystallization workshop, a hazardous waste warehouse, a packaging workshop, as well as auxiliary facilities for utility systems; the total construction area is 66,800 square meters. 3. The core processing route receives high-organic-content saline wastewater and waste industrial salts from chemical enterprises in the park; through a series of processes including pretreatment to degrade organic substances, membrane separation, wet oxidation, high-temperature oxidation, and salt separation via evaporation and crystallization, it purifies the materials to produce qualified industrial salts such as sodium chloride and sodium sulfate ； The purified water is supplied as reclaimed water for reuse by enterprises in the park, achieving near-zero wastewater discharge and the resource utilization of waste salts. II. Bidding Information 1. First-phase EPC general contract bidding (core section) – Bidding start date: Public bidding to commence in September 2025 – Bidding agent: Hebei Province Complete Set of Projects Bidding Co., Ltd. – Announcement of the winning bidder: November 10, 2025 – Winning bidder: China State Construction Third Engineering Group Co., Ltd. (consortium: China Light Industry Changsha Engineering Co., Ltd.) – Scope of work: All aspects of design, equipment procurement, civil construction, installation and commissioning, as well as trial operation and handover for the first-phase project. 2. Other related tenders are being carried out simultaneously, including tenders for supervision of the first-phase project, site survey, specialized procurement of equipment (membrane systems, evaporation crystallization units, oxidation reactors), safety assessments, environmental impact evaluations, and review of construction drawings, as well as other associated services ； Subsequently, the preliminary work and construction bidding for Phase 2 will be launched in accordance with the project progress. 3. Features of the bidding process: All bidding is carried out in a standardized and transparent manner on the Hebei Province Public Resources Trading Platform. The projects have a strong environmental protection focus, and bidders are required to have experience in treating chemical wastewater and waste salts, as well as qualified capabilities for undertaking large-scale environmental protection projects. III. Construction Progress 1. Preliminary Procedures: The construction land use planning permit was obtained in July 2025; meanwhile, the environmental impact assessment, energy assessment, and safety pre-assessment were completed and registered ； Complete site grading and fencing installation by the end of 2025. 2. On-site construction progress: The first phase of the project will officially commence construction in the first quarter of 2026 ； As of May 2026, the project is in the stage of main civil construction, with pile foundations, foundations, and the reinforcement formwork for some workshops being constructed simultaneously ； The public utility pipelines and temporary water and electricity facilities are constructed simultaneously. 3. Construction management is overseen in full by China State Construction Third Engineering Bureau on-site, with Changsha Engineering of China National Light Industry providing support for process design ； The supervision unit is responsible for overall quality, safety, and schedule control throughout the process ； The project strictly adheres to the special construction specifications for hazardous waste environmental protection projects, imposing strict controls on the construction standards related to leakage prevention, corrosion resistance, and exhaust gas treatment. 4. The first phase of the production plan calls for the completion of construction, joint commissioning, and commencement of operations by 2027 ； Phase II of the project will be launched at an appropriate time, depending on the increase in waste generation in the Lingang Chemical Industry Park. IV. Significance of the Project 1. From an industrial environmental protection perspective, the Cangzhou Lingang Development Zone is home to a large number of enterprises in the fine chemicals and new materials sectors. High-concentration organic-containing saline wastewater and waste salts have long been key environmental constraints that hinder the expansion of operations in this zone. This project focuses on the treatment of hazardous waste, liquid waste, and salt waste within the industrial park, replacing the traditional approach of outsourcing these wastes for landfill disposal. It significantly reduces the environmental risks associated with the transfer of hazardous waste, frees up environmental capacity in the chemical industry park, and supports the sustainable development of the regional chemical industry. 2. At the level of resource recycling, these projects establish a circular chain that connects chemical hazardous waste, recycled water, and industrial salt. Recycled water is reused in production, thereby reducing the need to draw on groundwater; purified industrial salt is reintroduced into the chemical industry chain, transforming pollutants into usable resources. This truly achieves the conversion of waste into valuable resources, in line with the policies related to carbon neutrality and the circular economy. 3. At the regional economic level, as a key environmental protection infrastructure project in Hebei Province, it aims to address the shortcomings in environmental protection facilities in the Lingang Economic and Technological Development Zone, thereby attracting more green chemical projects to be established there ； It also creates employment opportunities in the fields of environmental protection equipment and operation and maintenance services. It serves as a large-scale demonstration project for the recycling of high-salt organic waste liquids and salts in North China, providing a replicable model for the disposal of hazardous waste in similar chemical industrial parks across the country. 4. At the policy compliance level, it meets the stringent requirements set by ** and Hebei Province regarding the reduction, recycling, and harmless treatment of wastewater and solid waste in the chemical industry; this helps to minimize the potential pollution caused by salt-based pollutants in coastal waters and groundwater, thereby contributing to the protection of the marine ecosystem in the Bohai Bay New Area.
