The effectiveness for the XZEH medicine wastewater treatment biotechnology was conducted. The results show that it needs to increase 28% of the aeration tank volume in order to meet the effluent COD concentration at the first grade wastewater discharge standard level in China. If the engineered strain Xhhh and informatics software (Ebis) were used, the specific degradation rate of Xhhh strain may be higher 128% than that of the natural bacterium XZ strain and the aeration tank needed may be 51% decreased. This should be a potential technical patch for improving the biotechnological effectiveness and making the effluent at the first grade discharge standard.
