Abstract


The papers for the study, a semi-synthetic antibiotic production wastewater ferment synthetic wastewater generated in the semi-synthetic antibiotic production process , a high concentration of organic matter , complex composition and toxicity . The pharmaceutical industry is a high water consumption , serious pollution industries. With the advance of the national energy-saving production row , continuous adjustment of the national industrial policy , environmental regulatory efforts to continue to increase , the existing wastewater treatment facilities can not meet the needs of industrial development , the need to improve wastewater treatment process to achieve discharge standards . Fenton ( Fenton ) oxidation technology is based on the ferrous sulfate and the generation of hydrogen peroxide having a strong oxidation of the hydroxyl radical (· OH) to remove contaminants . Chemical oxidation is an effective way to solve the wastewater BIOREFRACTORY degradation and biochemical inhibition , especially for some of the wastewater component complex difficult biochemical degradation products , the biochemical inhibitor pharmaceutical wastewater , fully rely on the biodegradation pathway not only waste water of organic pollutants are not completely removed and the biochemical inhibitor wastewater will directly affect the biochemical degradation efficiency . Chemical oxidation law allows wastewater biodegradable and biochemical suppression issues are effectively addressed . Targeted chemical oxidation treatment technology , can reduce the dilution do not even have water , but also to ensure that the effluent discharge standards , and reduce the pollution of the natural ecological environment , to explore a new approach for the treatment of high strength wastewater with significant . Therefore , has a strong practical significance in the development of cost-effective treatment methods . In this thesis through the test oxidant ( H 2 O 2 < / sub > ) , catalyst (FeSO 4 ), reaction time and pH affect COD removal the main factors to conduct feasibility studies to establish the optimal conditions of Fenton oxidation process . Rear Fenton (Fenton) oxidation process , based on the actual project to transform the existing wastewater treatment facilities , wastewater discharge standards and test data .
