On the basis of full investigation of wastewater treatment plant(WWTP)operation and water quality of effluent from enterprises,the combined process of modified AO-Fenton oxidation-high efficient clarifier-activated carbon adsorption is used for treatment of industrial park wastewater which contained low concentration of organic nitrogen and refractory organic pollutants.The AO process is optimized,and the effluent meets the requirements of Quasi-Ⅳ class of surface water standards(TN ≤ 12 mg/L).The capacity of this plant is 2× 104 m3/d.The total investment of the project is 158.19 million yuan and direct operation cost is 3.863 yuan/m3.The effluent also meets the requirements of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(DB 32/4440-2022)of Jiangsu Province.It shows that the main process not only has strong adaptability and stability,but also has certain prospective.
