摘要
对各种多余污水处理技术的特点和适用范围进行了分析。根据部分油田的供水现状、污水性质和废热利用职权现状,提出了利用天然气发电机或锅炉产生的大量高温废气,将多余污水加热蒸发并冷凝成工农业生产用水的汽、液、固三相流的技术。介绍了采用该项技术的关键工艺及新型蒸发器的工艺原理、流程,并对照传统的污水回灌技术对其进行了经济分析和评价。
The characters and applied scope of sewage disposal technology are analyzed. According to the status of water supply,the characters of redundant sewage and the utilization state of waste heat energy in oilfields,the three-phase fluid technology is discussed chiefly. By adopting the three-phase fluid technology,the sewage was heated by the high-temperature exhaust gas from gas turbine or boiler and then condensed into vapor-liquid-solid three-phase fluid suitable to industry and agriculture. The craft flow and key procissing of the new type evaporator for the sewage disposal technology are introduced. The economic analyses and evaluation are given in contrast against the traditional sewage injection technology. By using the new technology,the cost of sewage disposal is lowered,and the great economic benefit has been achieved. On the other hand,the wastewater will decrease,which is beneficial to the environmental protection.
