摘要
在大量试验工作的基础上，本研究采用聚丙烯酸钠作为主要絮凝剂、木质素作为助凝剂、天然沸石作为吸附剂预处理味精浓废水，取得了十分好的效果。预处理过程对ＣＯＤ、ＳＳ、ＳＯ２－４的去除率分别达到６９％、９１％和４３％，预处理药剂费用约为６．２４元／吨废水，分离的ＳＳ蛋白经济获益约２７元／吨废水。
s:Sodium polyacrylate, lignin and natural zeolite were selecteol as key coagulant, coagulant aid and dsorption agent in this pre-treatment research on monosodium glutamate wastewater. Through the pre-treatment, the removal efficiency of COD reached 69%、SS 91% and SO 2 4 43%. By the SS reusing, a 27 yuan/ton wastewater benifit with the chemicals cost of 6.24yuan/ton wastewater was obtained.
