| 摘 要： | 对某养鸡场沼气工程全混式发酵罐出水沼液混凝投药量预测模型进行了研究.采用回归分析法确定了混凝剂最优投加量的模型参数；通过回归正交试验研究了助凝剂最优投加量影响因素,建立了助凝剂最优投加量预测模型；通过中试试验,对所得投药量模型进行了验证.结果表明,混凝处理沼液混凝剂最优投加量模型为A=0.000 06C1.41；助凝剂最优投加量模型为B=0.000 148CN -0.014 2C -0.277N+ 26.7,原水CODcr及搅拌强度是影响助凝剂PAM投加量的重要因素；经统计检验及中试试验验证,表明所建预测模型准确可靠.

| Abstract: | An investigation was carried out on modeling of optimal dosage prediction for coagulation treatment of CSTR fermentation tank effluent of a biogas project.The parameters of optimal coagulant dosage model were determined using regression analysis.Influencing factors of optimal coagulant aid dosage were studied through orthogonal regression experiment,then optimal coagulant aid dosage model was built.Finally a pilot experiment was carried out to verify the reliability of the models.Results showed the model of... |
