| 摘 要： | 目的]研究固定化藻菌去除淡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AR关系模型。结果]五因子对AR均具有显著影响,最佳去氨氮组合为：温度30℃、pH值7.0、光照强度6000lx、溶解氧5.0mg/L、填充率10%。根据试验数据拟建的方程模型决定系数R^2=0.8648、相伴概率P〈0.05,对AR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了参考依据。 |

| Abstract: | Objective]The aim was to research the effect of immobilized algae-bacteria removal ammonia nitrogen of aquaculture wastewater and model construction. Method]Immobilized algae bacteria (ABI) was applied to remove ammonia of freshwater aquaculture wastewater. Five tactor of temperature (T),pH,light intensity (I),dissolved oxygen (DO) and filling rate were used for Multi-factor orthogonal test and related data between ammonia removal and five factors was received,then relations model between the five factor and nitrogen removal was established.Result]The results showed that five-factors had significant effect on AR,and the best combinations for removing AR was temperature 30 ℃,pH7.0,light intensity 6 000 lx,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<0.05. Samples T-test was done between the model predictions and the actual measured values,and the results showed that the significant difference of overall mean value sig. (2-tailed) was 0.978 (P>0.05),which indicated that there was no significant difference between model predictions and the actual measured value,and model had a high degree of fitting. Conclusion]The study provided a reference for realizing removal ammonia nitrogen of aquaculture wastewater and concentration decline. |
