Microbial Degradation Of High Concentration Organic Wastewater Applied Research

Fumaric acid-containing organic wastewater and camphor-containing organic wastewater are biodegradated by highly-effective degrading bacteria, and be treated with the method of anaerobic hydrolytic-aerobic treatment, conbining with the method of pretreatment by microelectrolysis of iron-carbon and activated carbon-hydrogen peroxide method.With anaerobic bacteria Y12,the CODcr removal rate of Fumaric acid-containing organic wastewater reached 64.5%, that of camphor-containing organic wastewater reached 67% .With aerobic bacteria H12, the CODcr removal rate of fumaric acid-containing organic wastewater reached 76.4%, that of camphor-containing organic wastewater reached 76. 5% . Using the method of PACT, the CODcr removal rate of Fumaric acid-containing organic wastewater reached 86% with the bacteria TH.After the anaerobic hydrolytic treatment, at 18h , the CODcr removal rate of fumaric acid-containing organic wastewater reached: H1: 72.3%, H2: 70.2%, H12: 88.2%. Without the anaerobic hydrolytic treatment, at 24h , the CODcr removal rate of fumaric acid-containing organic wastewater reached: H1: 19.04%, H2: 8.94%, H12:37.55%.At the same situation, with rot fungus, the CODcr removal rate of fumaric acid-containing organic wastewater which has been removed thiourea reached 90%, that of fumaric acid-containing organic wastewater without thiourea-removal is 72%. Sothat thiourea can retrain the white rot fungus during the degradation. The degradation effect of fumaric acid-containing organic wastewater is better than that of camphor-containing organic wastewater.The effect of microbial activated carbon-exposure to air is better than that of the microbial-exposure to air. The CODcr removal reached 83. 2% at 40h.
