This paper analyzes the common characteristics of natural gas purification wastewater and researches anaerobic biodegradation of the wastewater through cultivating it.

Because the natural gas industry develops, the natural gas purification wastewater is becoming one of wastewater pollution sources, if this kind of wastewater is not been disposed, will be certain to impact the serious consequence on the natural environment.

The Research on the Treatment of Natural Gas Chemical Industry Wastewater with Membranes Separation Technology;

The Research Institute of Natural Gas Technology has worked hard for 50 years in the field of natural gas purification technology,achieved a total of more than 130 scientific research projects,5 state-level awards,14 provincial and ministerial level awards,48 regional awards,created 13 patents and proprietary technology.

The main task of natural gas purification is getting rid of the suffered hydrogen, Organic sulfur, carbon dioxide and other harmful subjects in the raw natural gas, and provides clean and good quality natural gas, and produces sulfur by using the sulfur compound from the purification process .

Due to the great fluctuation in water quality and quantity and the high content of refractory organics of wastewater of natural gas purification plant,the effluent can hardly realize stable and standard discharge Treating the natural gas purification wastewater by h.

The process design,start-up,commissioning and other circumstances were mainly introduced for Zhongxian Natural Gas Purification Plant in this paper,The features and the related problems of the plant were evaluated,and a few suggestions were proposed for design and commissioning of the gas purification plant.

This Paper reviews the current status of application of membrane separation technology to natural gas processing at home and abroad, and introluces the working principle of gas membrane separation and its application in the fields of gas purification, helium extraction and membrane reaction.
