| 中文摘要 |
| 就目前较难处理的高浓度味精废水用厌氧法进行了稳态运行的控制研究。在中温条件下,获得了高浓度味精废水高效稳态运行的控制参数。COD去除率可达70%以上,产气量可达10.5m3/m3·d,其中甲烷含量占58%以上。表明高浓度(谷氨酸)味精废水进行厌氧处理是可行的。 |
| 英文摘要 |
| Anaerobic treatment of high concentrated monoso-dium glutamate proce sing wastewater(COD 60000-80000mg/L), which is so far very difficuls to be trea-led biologically, was conducted and the steady state control of the treatment process for the optimal efficiency under different operating parameters(COD loading rate, hydraulic retention time and pH)were demonstrated in this paper. The experimental results showed that COD removal could reach more than 70%, biogas production rate was as high as 10.5m3/m3·d with more than 58% of methane content under the controlled conditions of hydraulic retention time of 84 hours, COD loading rate of 6-8%, pH of 6.5-7.5 and medium temperature. |
