| description | The high-strongth antibiotics production wastewater containing toxic and refractory substances treated by lab-scale mesophilic hydrolization-acidification reactor was described, and the reaction dynamic mechanism was investigated, too. When the reactor was operated in influent COD<sup>Cr</sup> 5000-6000 mg/L and HRT of hydrolization-acidification reactor and UASB 7 h and 14 h, separately, the volumetric COD loading rate and COD removal rate reached 10.62 kg/(m<sup>3</sup>·d) and 70%-80%, respectively, which will in accord with the influent demand of followed aerobic treatment. The reaction mechanism tallied with the amended Monod equation. The anaerobic kinetic constants of v<sub>max</sub> and K<sub>i</sub> for the wastewater treatment were 0.1-0.3 d<sup>-1</sup> and 2.3-3.0 mg/L. therefore a valuable suggestion for the optimization of design and operation of the anaerobic treatment system was put forward. |
