Project Case of a Reclaimed Water Plant in a High-tech Zone of Jiangsu Province
A regeneration water plant in a high-tech zone in Jiangsu uses pre-treated wastewater from various enterpris-es as raw water. The combined process flow of chemical precipitation,biochemical treatment,ultrafiltration,and reverse osmosis membrane separation is used to treat phosphorus and non phosphorus containing wastewater separately in differ-ent stages. The system is designed reasonably and has good processing effects,with a direct operating cost of 6.25 yuan/m3. The effluent quality meets the requirements of Class Ⅳ standard in the Environmental Quality Standards for Surface Water(GB 3838—2002) and is provided to relevant enterprises in the high-tech zone for reuse.
