Application and optimization of two segments DTRO in the deep concentration and reduction of coal mine water
Based on the principle of large reflux of concentrated water,two segments DTRO systems were used to treat coal mine water for the deep concentration and reduction.The operating performance of the system was studied under various operating conditions,the relationship be-tween salt content,recovery rate,operating pressure and output water quality were investigated.The actual situation shows that the desalination rate of two segments DTRO is above 99.6％,and the recovery rate reaches 50％.The overall work of the system was stable,and there was no obvi-ous membrane pollution blockage and water production decline in continuous operation for more than three months.The optimization problems of DTRO system,such as the impact of concentrat-ed water cycle,safe operation of high pressure pump,vibration and noise impact,system startup and flushing,security filter contamination,abnormal performance of membrane elements,were analyzed and optimized.It provides a positive reference for the long-term stable operation of two segments DTRO system in the application of coal mine water for the deep concentration and reduc-tion.
