MBR membrane process in the coking wastewater studying


The coking wastewater is a waste water with a large amount of water in the coking enterprise's effluent, and difficult to handle. The characteristics of coking wastewater are: Ammonia is high, and it contains many toxic and harmful substances such as cyanide and sulfide. The components are complex, the biodegradation of organics in water is difficult, and the concentration of pollutants is high. The biodegradability of wastewater is poor and it belongs to high-concentration organic wastewater that is difficult to biodegrade.


The existing coking enterprises commonly used in wastewater treatment are biochemical method, advanced oxidation method and physical chemical method. However, they all have complicated operations and unstable discharge quality. In order to solve the coking wastewater is not easy to discharge, serious pollution and other issues. After thorough investigation of the water quality, a coking wastewater plant considered the use of RisingSun MBR membrane process for advanced treatment of coking wastewater. Based on this process, pilot test verification was carried out. Selecting MBR process as RO pretreatment process can further improve the quality of biochemical effluent water, and provide stable and safe protection for the subsequent stable operation of the process. Therefore, determining the appropriate MBR operating parameters and evaluating its water production effects and exploring the stability and safety conditions of reverse osmosis are the innovation points and important objectives of this pilot experiment study. At the same time, through the pilot test, the optimized operating parameters and effluent quality of the MBR system were determined. The tolerance and stability of the RO system during the experiment were examined, and the selection of the process parameters and the operation basis were provided for the follow-up engineering design.
