摘　　要：采用厌氧反应器和气体计量装置,对不同条件下的洁霉素废水的厌氧可生化性进行了研究。考察了COD容积负荷,添加营养物和微量元素,预处理、混入含抗生素废水,及添加EM原液对废水厌氧生化性的影响。试验结果表明:洁霉素废水厌氧可生化性较差,在厌氧条件下最高COD去除率约为62%～72%,但高浓度对厌氧菌的抑制性并不强,COD的质量浓度高于13.32g/L时才稍有影响。该废水经过微电解或水解酸化处理后厌氧可生化性稍有提高。添加微量元素和营养物质后,混入含抗生素废水后,或添加EM原液后均未发现对该废水的厌氧可生化性产生大的影响。Anaerobic reactor and gas metering device were adopted to study the anaerobic biodegradability of lincomycin hydrochloride wastewater under different conditions. The effects of COD volume loading, adding nutrients and trace elements, pretreatment, mixing antibiotic-containing wastewater, adding EM raw liquid on the anaerobic biodegradability of the wastewater were investigated. The results of the test showed that： the anaerobic biodegradability of the lincomycin hydrochloride wastewater was not so good, the highest removal rate of COD was about 62% - 72% under anaerobic condition, however, high concentration had not so strong inhibition ability to anaerobic microorganisms, and there was only a little restraint when the mass concentration of COD was higher than 13.32 g/L. The anaerobic biodegradability of the said wastewater was improved slightly after be treated by micro- electrolysis or hydrolysis acidification process and didn＇t change very much after adding trace elements and nutrients, mixing antibiotic-containing wastewater, or adding EM raw liquid.
