Summary of Desulfurization Recycle Water Purification Test and Application
After long-term recycling of desulfurization recycle water,the turbidity increases and the color turns yellow,which affects the washing effect of desulfurization gas.Using activated carbon as an adsorbent,the effects of activated carbon dosage,stirring time,and stirring rate on the treatment efficiency of recycle water are investigated through laboratory experiments.The results show that adding 1.0%activated carbon and stirring at a rate of 300 r/min for 15 minutes can achieve satisfactory treatment results.Industrial trial runs are conducted using YNK-655 liquid-phase sulfur pollutant adsorbent and YNK-680 flocculant.The results show that the turbidity of the treated recycle water is less than 5 NTU,which can meet the requirements of recycle water purification treatment.
