摘要
在柱式反应器内，用泽沼红假单胞菌Ｙ６连续处理尼龙６６盐生产废水，当进水（ＣＯＤｃｒ含量）为１１４０ｍｇ／Ｌ，经过６０ｈ处理后出水中ＣＯＤｃｒ含量为１５０ｍｇ／Ｌ，光合细菌浓度（干重）为５．５９ｇ／Ｌ，建立了动力学模型，其参数Ｋｓ＝８４８ｍｇ／Ｌ，Ｙ＝０．４４７，Ｋｄ＝０．０１７３ｈ－１，μｍ＝０．２１ｈ－１，用所得到的动力学参数预测出水质浓度和菌体浓度，其预测值和实测值相对误差小于４％。
The wastewater discharged from the plant of production of Nylon-66 salt in CSTR after polymers in the wastewater have been extracted. Different experimental condition was tested. When the reaction time 60 h, the light intensity 4 000 lx, the temperature of reaction is in the range of 28～30℃, DO 1.0 mg/L, the concentraction of the wastewater before treated S 0 1 140 mg/L, the concentration of discharge from the reactor S f=150 mg/L. The concentration of PSB X is 5.59 g/L(by dry mass). With the data obtained from the experiment, the knetic coefficients of the model was calculated: K s=848 mg/L, Y =0.447, K d=0.017 3 h -1 ,μ m=0.21 h -1 and the model was made. The data simulated with the model are concordant with that of experiment with a relative error being less than 4%.
