Representative projects:
Invested by SIIC and China Baowu Steel Group Corporation Limited ("China Baowu"), Shanghai Baoshan Renewable Energy Utilization Center Project ("Baoshan Project") stretches over 33 acres and costs 3.041 billion RMB. Baoshan Project is designed to have a 3,000-ton-per-day solid waste incineration capacity and an 800-ton-per-day wet waste treatment capacity, and is expected to generate 8,000 GWh of electricity per year. Ever since Shanghai started implementing garbage sorting, Baoshan Project is the first domestic waste end disposal facility to be built that treats solid waste and wet waste in a combined way. The Project is to work as a way out of surrounding-area domestic waste disposal. By raising waste reclamation rate and improving the city's infrastructure, it is of great significance for Shanghai to achieve its goal of "zero land-filling for domestic waste". Designed to the highest international standards, Baoshan Project is armed with first-class technology and equipment, and executes the most strict emission standards. Also a neighbor-friendly plant, the Project would generate no odor and have no transport vehicle visible. It is also designed to have the function of education, training, culture activities and sports, and will be completely open to public in the future.
Baoshan Project is currently under construction, and is expected to commence operation in 2022.
Wuhan Hanxi Wastewater Treatment Co., Ltd. is a joint venture company. Its shareholders are SIIC Environment Holdings Co., Ltd., SIIC Environment Holdings (Wuhan) Co. ltd. and Wuhan Urban Drainage Development Co., Ltd. The total investment amount is about 1.2 billion. The investment was processed in two phases.The investment amount for phase I is RMB 463 million and the investment amount for phase II is RMB 720 million. The capacity is 400,000 tons/day for phase I and 600,000 tons/ day for phase II. The capacity is expected to be 800,000 tons/day in the next 2-3 years. This project is the largest wastewater treatment plant in central. The main process is a modified A2/O biological treatment process.
Hanxi Wastewater Treatment Plant currently serves west part of the main city in Hankou. The service area extends from Xinhua Road in the east, to Wujiashan Taiwanese Investment Zone near Han River in the waste, and to the river embankment in the north, with a service area of 176.7km2. The long-term service population will reach 1.725 million. The mean process Hanxi Wastewater plant uses is a modified A2/O biological treatment process. The modified A2/O biological reactor adds a selective zone (pre-anoxic zone) in front of the anaerobic zone of the conventional A2/O process. The returned sludge from secondary tank and 10% of the wastewater enter the selective zone. The residence time is about 20 to 30 minutes. The microorganisms use about 10% of the influent organic matter to remove the return nitrate nitrogen and eliminate the adverse effects of nitrate on the anaerobic tank, in order to ensure the stability of anaerobic process and improve efficiency of phosphorus removal. At the same time, the modified A2/O biological treatment process retains the reflux of the mixed liquor in the conventional A2/O process, thus ensuring the denitrification effect. The sludge aerobic fermentation workshop in Hanxi adopts high-temperature aerobic fermentation technology to decompose unstable organics through microbial activities, and uses continuous high-temperature process generated in microbial metabolism to kill pathogenic bacteria and weed seeds, helping moisture removal. All the sludge is detoxified to harmless products and achieved the 3R (Recycle, Reuse and Reduce) rules. The deodorizing system treats waste odor molecules by using biological membranes specially cultivated on the biological filler in the biological filter.
The company passed environmental management system certification, quality management system certification and occupational health and safety management system certification (ISO 14001, 9001 &18001). Through advanced technology accumulation, excellent team and its operation methods, Hanxi Company has successively obtained the Advanced Wastewater Treatment Operation Company in Wuhan and Wuhan City's “Eleventh Five-Year” Advanced Environmental Protection Group.
