Abstract:

By means of monomer test, repetition test and relative action test, the effect of the suppressive substances in the anaerobic digestion process of penicillin wastewater and its concentration on the treatment efficiency has been investigated.The research indicates that the suppressive substances in the anaerobic digestion process of penicillin wastewater are mainly de-emulsifier 1231 and SO₄^2-.When anaerobic biological method is used for treating penicillin wastewater, the influent water mass concentration of de-emulsifier 1231 and SO₄^2- should be less than 200 mg/L and 1 000 mg/L, respectively.

Key words: penicillin wastewater, anaerobic digestion, suppressive substances

摘要：

采用单体试验、重复试验、相互作用试验考察青霉素废水厌氧消化过程中的抑制性物质及其浓度对处理效果的影响.研究表明,青霉素废水厌氧消化的抑制性物质主要是破乳剂1231和SO₄^2-.采用厌氧生物法处理青霉素废水时,需将破乳剂1231的进水质量浓度控制在>200mg/L,将SO₄^2-的进水质量浓度控制在>1000mg/L.
