- 摘要:
- 天然气厂站常规排水收集系统是以市政工程排水规范为基础，采用“来水-排水检查井+排水管道-污水处理装置”的敞开式排水系统，天然气厂站排放污水中有毒、有害物质的挥发，造成安全生产和职业健康隐患。随着安全环保和职业卫生要求的不断提高，传统厂站的有毒、有害污水收集系统模式已不能适应气田的发展需求。应进一步研究和改进污水收集系统技术，不断提高污水收集系统的设计水平，在保证生产的同时，关注生产操作环境、保护生产人员的身心健康，对厂站有毒、有害污水收集系统进行密闭化设计。通过对国内外天然气厂站生产污水收集和排放系统设计工艺的分析，提出了较为合理、便于实施的有毒、有害污水收集系统的设计思路。
Waste water drained from natural gas treatment plant contains toxic and hazardous substances， such as chemicals and condensate oil. Conventional open waste water drainage system applied in gas treatment plant design is based on municipal engineering norms and usual practices， in which adopted is the waste water treatment and drainage way of “effluent-drainage inspection wells plus drainage pipes-waste water treatment unit”. Such system can cause serious safety and occupational health risks due to evaporation of toxic and hazardous substances in waste water. With more and more strictness of safety and environmental protection and occupational health requirements， conventional waste water drainage practices can not meet demands in gas field development. Application of closed waste water drainage system in natural gas treatment plant design is imperative in order to reduce safety and environmental protection and occupational health risks. Analyzed are design processes of waste water drainage system in natural gas treatment plants at home and abroad and put forward are more reasonable options for such drainage system design.
