Abstract
Abstract
The performance of the combined biological and three-dimensional electrochemical treatments was studied for the industrial wastewater from sewage treatment plant. The process parameters were investigated.Result showed that the system could remove over 99.13% COD,63.88% TN,99.42% TP and 25.0% NH3-N in 2h. Under the operating conditions of voltage 8V, electrolysis 120min, addition of 2000mg/L electrolyte KCl and 30g industrial waste steel slag, the degradation of pollutants is effectively improved. And through economic analysis, it can be calculated that it only costs 2.2CNY/t to process one ton of industrial wastewater. The experimental results not only meet the water discharge standards, but also pave the way for developing techniques with high efficiency, economy, low energy consumption and universal use.
