Design and operation of wastewater treatment project for lithium battery production
Based on the water characteristics of lithium battery production wastewater, the cathode wastewater was combined with the anode wastewater after pre-treatment, and then treated by a combination process of electro-Fenton-coagulation-DF-anaerobic reactor-AO. The results indicated that this process had a high removal rate of pollutants in lithium battery wastewater, with removal rates of Ni, CODCr, BOD5, NH3-N, TN, TP, and SS as 89.3%, 98.7%, 97.6%, 94.9%, 84.5%, 93.6%, and 98.5%, respectively. The effluent could meet the indirect emission standard requirements in Table 2 of new enterprises in Emission Standard of Pollutants for Battery Industry(GB 30484-2013). Finally, it analyzed and studied the engineering investment, operating costs. The process was used to treat lithium battery production wastewater, with designed treatment capacity of 1 000 m3/d. The total project investment was 8.66 million yuan, including 4.35 million yuan for civil engineering and 4.31 million yuan for equipment. The operating costs included electricity, chemical agent, labor, and sludge disposal fees. When the actual water volume was 900 m3/d, the total operating cost was 7.48 yuan/m3, which provided reference for the treatment of similar enterprise production wastewater.
