电解絮凝-生物炭滤池法处理印染废水

The treatment of dyeing wastewater by the electrocoagulation-biological activated carbon filtering reactor process

采用电解絮凝 -生物炭滤池串联工艺对印染废水进行处理研究。实验结果表明 ,控制电解在 2 8A m2 的电流密度和 2 0min的停留时间下运行 ,而调节生物炭滤池接触反应时间在 15 0min ,处理后的出水CODCr、BOD5及色度等指标能达到纺织染整工业废水的I级排放标准。同时 。

The electrocoagulation-biological activated carbon(BAC) filtering reactor process was applied for the treatment of dyeing wastewater. Through preli minary research, the optimized working conditions of the process were that the electrolysis should be operated under the current density of 28 A/m 2 and the remaining time of 20 min. And the working time through the BAC filtering reactor should be controlled under 150 min or so. The results of the experiment showed that the COD?BOD 5 and shade of the treated wastewater through the process were all below the national standards on industrial effluent discharge. At the same time, the better dephosphorization effect could be obtained through the process.
