The key technology of EGA purification tank is that it overcomes the defect of the traditional sewage treatment process design in biochemical reactor technology, adopting MBBR biological treatment technology, by adding the suspension in the biochemical pool biological active filler, greatly increased the amount of microbial reactor and microbial population, make all kinds of pollutant in the sewage and the interpretation of radically remove, in order to stable water discharging standard provides a powerful guarantee.

The treatment process of EGA purification tank adopts AO+MBBR process, and the removal of pollutants such as organic matter, ammonia nitrogen and total nitrogen mainly depends on the biological treatment process in the reactor.
