摘要
采用两相EGSB处理模拟皮革废水,在40d的实验运行期间,跟踪观察了COD和硫化物的脱除及pH值的变化以及污泥的生物特性变化,发现EGSB反应器的有机负荷由3.2kg COD/(m3.d)逐渐提高到17.41kg COD/(m3.d),COD的去除率稳定在88%左右,而且进水硫化物也得到了有效的去除,驯化出了对硫化物有较强忍耐力的产甲烷菌。
Simulation tannery wastewater was treated with two-phase EGSB reactor. During the experiment,the changes of COD, sulfide, pH and bio-characteristic of sludge were investigated. The results show that the OLR of EGSB reactor reaches 17.41 kg COD/（m^3.d） from 3.2 kg COD/（m^3.d）,the removal rate of COD is about 88%, and the rate of desulfurize is rather high. The methanogenic bacterium with hizh sulfide endurance is zot in our exoeriment.
