为优化某味精废水处理工程的操作,研究了其除碳脱氮动力学特性.结果表明,对COD的最大比去除速率为0.110 kgCOD/(kgVSS·h),最大容积去除速率与实际容积负荷之比为17.28～21.12,最大比去除速率与实际污泥负荷之比为13～21,饱和常数KS为202 mgCOD/L;对氨氮的最大比去除速率为0.014 1 kgNH4+-N/(kgVSS·h),最大容积去除速率与实际容积负荷之比为8.86～11.25,最大比去除速率与实际污泥负荷之比为7～11,KS为19.1 mgNH4+-N/L,表明该工程去除COD和氨氮的潜力还很大,容易实现达标排放.当以葡萄糖为碳源时,对硝态氮的最大比去除速率为0.014 0 kgNO3--N/(kgVSS·h),KS为13.5 mgNO3--N/L;当以醋酸盐为碳源时最大比去除速率为0.024 4 kgNO3--N/(kgVSS·h),KS为12.0 mgNO3--N/L,表明醋酸盐比葡萄糖更有利于提高反硝化速率和强化脱氮效果.

The kinetic characteristics of biological nitrogen and carbon removal from monosodium glutamate wastewater were investigated to optimize a treatment project. For COD, the maximum specific actual loading rate is 17.28 to 21.12, the ratio of vmax to the actual sludge loading rate is 13 to 21, and the value for saturation constant (KS) is 202 mgCOD/L. For NH4+-N, the vmax, is 0.014 1 kgNH4+-N/ the ratio of vmax to the actual sludge loading rate is 7 to 11, and the Ks is 19.1 mgNH4+-N/L. These show that this project has enormous potential for removal of COD and ammonia nitrogen. When glucose is 13.5 mgNO3--N/L respectively. When acetate is used as carbon source, the vmax and KS are 0.024 4 glucose in increasing denitrification rate and enhancing nitrogen removal efficiency.
