Activated Coke Coupled with Surface Wetland Technology for Treating Effluent from Waste water Treatment Plant of Textile Industrial Park
This study presents the design of a wastewater treatment plant for a textile industrial park,with a capacity of 30 000 m3/d initially and 90 000 m3/d in the long term.The effluent meets the Class A standard of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002)and is treated using a combination of activated coke adsorption and surface wetland technology.The system ensures that key discharge parameters consistently achieve the Class IV water quality standard of the Environmental Quality Standards for Surface Water(GB 3838-2002),facilitating the reuse of water for industrial processes and promoting zero wastewater discharge.The engineering design,operational parameters,and performance outcomes are discussed,highlighting significant environmental,ecological,economic,and social benefits,thus providing a valuable reference for wastewater resource reuse in textile industrial parks.
