The inhibitory effect of streptomycin on methane production of anaerobic granular sludge treating starch wastewater was investigated. The results indicated that the methane production of anaerobic granular sludge was influenced in the presence of streptomycin ranged from 0 to120 mg/L. The larger final methane production, the less remaining COD and the higher final pH value at the end of tests were...
The alkaline wastewater from oil refinery is a high concentration alkaline wastewater, which contains a great deal of sulfide, phenol and oil pollutants. A novel two stage circulating biological aerated filter (CBAF) was used to treat the alkaline wastewater after its neutralization. The factors of various air/water volumetric ratio, hydraulic retention time (HRT), which affected the removal of COD,...
A four-compartment ABR with an effective volume of 28 L was used to investigate the application of an anaerobic baffled reactor (ABR) in treating sugar-producing wastewater. The results indicated that the reactor could start up at an influent OLR of 2.5 kgCOD/m3-d and temperature of 35degC. COD removal rate could reach 89% on the 5th day. Then the influent COD increased from 5000 to 8000 mg/L, HRT...
