含醇污水预处理工艺优化

Optimize process of sewage containing alcohol pretreatmen

榆林天然气处理厂担负着整个榆林南区生产污水的处理与回注、甲醇再生利用的任务,甲醇再生的质量、数量、污水回注工艺指标等对于周围环境保护、节能降耗有着重要影响。污水预处理工艺是含醇污水处理工艺的关键过程,预处理参数的好坏直接影响含醇污水的甲醇回收效率、污水回注指标和装置的处理能力,通过对预处理药剂加入、工艺操作进行分析、优化,使预处理后的各项参数达到最佳,提高装置处理能力,减少装置的堵塞和腐蚀,延长装置运行时间,使含醇污水处理后的各项指标达到最优化。

Yulin gas treatment plant responsible for the entire production of the Southern District of Yulin sewage treatment and reuse of injection, the task of recycling of methanol, methanol regeneration of quality, quantity, water recharge process indicators around environmental protection, energy saving has a significant impact on . Sewage pre-treatment with alcohol is the key technology of sewage treatment process, pretreatment parameters with a direct impact on the methanol alcohol recovery efficiency of waste water, sewage recharge indicators and device processing power, this article pre-treatment by the Pharmacy adding, process operation analysis, optimization, so that the parameters of pre-treated to achieve the best to improve the handling capacity of devices to reduce the device＇s plug and corrosion, extending the device run-time, so that the sewage treatment alcohol content of the indicators have reached the post - optimized.
