| 摘 要： | 介绍了非常规天然气采出水水质特点与回用要求,分析了预处理、二级处理、脱盐处理等单元的技术研究进展与潜在问题。分析认为:非常规天然气采出水水质复杂,呈现高COD、高TDS、高硬度、高氯化物等水质特征;针对有机物脱除难题,需进一步开发耐盐催化氧化技术、耐盐生化技术和高效抗污染膜浓缩新工艺;脱盐处理等单元应通过高级氧化工艺进一步降低有机物含量,促进浓缩结晶系统的稳定运行和结晶盐的资源化。

| Abstract: | The water quality and reuse requirements of wastewater produced during unconventional natural gas extraction were introduced.The research process and potential problems of pretreatment,enhanced treatment and desalination treatment technologies were analyzed.The results show that unconventional natural gas produced water has high concentrations of COD,TDS,chloride and high hardness,thus its water quality is complex.In order to remove organic effectively,it is necessary to develop new technologies such as salt-tolerant catalytic oxidation technology,salt-tolerant biochemical technology and anti-pollution membrane concentrate technology.It is suggested to further reduce organic content by applying advanced oxidation processes in desalination units for the stable operation of concentration and crystallization system and utilization of salt. |
