Coking wastewater is a kind of organic industrial wastewater which contains high concentration of ammonia and difficult biodegradation materials. In this article, several kinds of main treatment methods used in the coking wastewater control, such as physieo - chemical process and biological treatment method and so on are introduced. However, there are lots of defects in these treatment ways. In order to solve these problems, a type of new treatment method is put forward, that is, using EGSB reactor treating to coke wastewater under micro - aerobic conditions. The procedure compromises the merits of EGSB reactor and microaerobic technology. Besides, there are many advantages in the process, including simple circuit, few area and low investment. It is suitable for coking wastewater treatment.
