番茄加工厂废水处理系统好氧活性污泥生物活性指标的评价

Evaluation for biological activity of aerobic activated sludge in wastewater treatment system for tomato processing

研究了好氧高效菌群处理番茄酱加工废水过程中DHA、OUR、ORP、ATP和其他各项水质污染指标的全周期变化规律。结果表明,连续处理中DHA和入水pH、COD去除率有明显的相关性;OUR与F/M、温度有明显的相关性;ORP与DO、入水COD有明显的相关性;ATP和MLSS、SVI有明显的相关性。测定结果与处理系统实际运行状况基本一致,表明DHA、OUR、ORP和ATP的测定方法相比传统的污泥活性测定方法更加适用于番茄酱加工废水处理过程,并且具有准确性较高、控制更精细等优点。

The variations of DHA,OUR,ORP,ATP and the indexes of water pollution were measured and studied during treatment of wastewater from tomato paste processing plant（Shihezi Tianye Tomato Products Co.,LTD）using aerobic activated sludge.The results showed that for continuous treatment there was the correlation between DHA and COD removal rate as well as influent pH,between OUR and F/M as well as temperature,between ORP and DO as well as influent COD,and between ATP and MLSS as well as SVI,respectively.The measurement results were essential consistent with the actual running,indicating that compared with traditional methods measuring sludge activity,the measurement of DHA,OUR,ORP and ATP could be more suitable for wastewater treatment from tomato paste processing plant.Their advantages were of high accuracy and more fine control.
