The Steady State Control of Anaerobic Treatment for Monosodium Glutamate Processing Wastewater
味精废水厌氧处理稳态运行的控制研究

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.
