摘 要: | [目的]研究固定化藻菌去除水养殖废水氨氮效果及模型拟建.[方法]利用固定化藻菌(ABI)处理淡水养殖废水中的氨氮,采用多因子正交试验得到温度(T)、PH、光照强度(I)、溶解氧(DO)和填充率五因子与氨氮去除率(AR)之间的关系数据,拟建五因子与氨氮去除率关系模型.[结果]五因子对氨氮去除率均具有显著影响,最佳去氮氮组合为,温度30℃、pH值7.0、光照强度6 000 lx、溶解氧5.0 mg/L、填充率10%.根据实验数据拟建的方程模型决定系数R2=0.864 8,相伴概率P<0.05,对氨氮去除率的模型预测值与实际测值进行样本T-检验,结果表明总体均值差异显著值sig.为0.978(P>0.05),模型预测值与实际测值数据组无显著性差异,模型具有较高拟合度.[结论]为实现养殖废水中氨氮去除或浓度降低提供参考依据.Abstract:Applied Immobilized algae bacteria (ABI) to remove ammonia of freshwater aquaculture wastewater.Temperature (T),PH,light intensity (I),dissolved oxygen (DO) and filling rate five factors plays important role in the process of ammonia nitrogen removal,related data between ammonia removal and five factors was received through multi-factor orthogonal test,and established relations model between the five factor and nitrogen removal.The results show that five-factors had significant effect on AR,and the best combinations for removing AR was temperature 30 ℃,pH=7.0,light intensity 6 000 lux,dissolved oxygen 5.0 mg/L and the fill rate 10%.According to the experimental data,equation model was proposed and coefficient of determination R2=0.864 8,P<0O.05.Samples T-test was done between the model predictions and the actual measured values.Test results showed that the significant difference of overall mean value sig.(2-tailed) was 0.978 (P>0.05),it Shows that had no significant difference between model predictions and the actual measured value,and model had a high degree of fitting.
