摘要
为了改善污泥蛋白液的性能,对污泥蛋白液进行了60Coγ射线协同H2O2的实验研究,在正交试验的基础上,利用Matlab软件对试验数据进行了多目标优化,建立以发泡性、稳泡性、脱色率和气味测评为优化目标的数学模型。结果表明,p H8.69,H2O20.4%,辐照剂量2.0 k Gy,污泥蛋白液的性能最佳,此时蛋白液的发泡性是22.14 cm,稳泡性20.50 cm,脱色率64.15%,气味评价分数3.21。并进行验证实验,真实值与预测值高度吻合,证明了优化结果具有较强的可靠性。
In order to improve the performances of sludge protein solution, the sludge protein solution is studied by the experiment of 60 Co ray in combination with H2O2. Based on orthogonal test, multi-objective optimization of test data is carried out by using the Matlab software. The mathematical model is established by using the foamability ,foam stability, sensory score and decolorization rate as optimization objectives. The results show that the performance of sludge protein solution is best under the following conditions： 8.69 of pH, 0. 4% of H2O2 and 2. 0 kGy of irradiation dose. The foamability,foam stability, deeolorization rate and odour score can reach 22. 14 cm, 20. 50 cm, 64. 15% and 3.21, respectively, which is in good agreement with the predicted value. The verification experiment shows the reliability of the optimization result.
