摘要
背景与目的:乳品行业耗水量大,产生大量废水。研究的问题是可用水资源的缺乏,这反映在人均用水量的下降上。本研究的主要目的是研究生产单元的用水效率,估计水单元的现金收益,并研究影响其的因素。材料和方法:数据分析使用SPSS (Statistical Package for Social Sciences)第16版。定量数据以mean±SD表示。采用独立样本方差分析进行双向方差分析,采用Post-hoc (LSD)检验分析均数差异。概率值(P)小于0.05认为有统计学意义。结果:研究最重要的结果是研究期间人均年平均流失率较低,约为1.29%,水资源产业占比上升,增长率约为15.1%,在测量样本间水资源利用效率的显著性差异时,证明了统计模型在p<0.05水平上显著。此外,还指出了用水成本占总运营成本的比例差距,平均约为5%,并指出了低效率。结论:本研究为检验部门在处理高有机物含量工业污染物时如何长期处理这些设施和厌氧生物处理提供了明确的方案。
Efficiency of Water Resources in Small and Medium-sized Dairy Factories in Egypt
Background and Objective: The dairy industry consumes great amounts of water and generates large quantities of wastewater. The study problem is the lack of available water resources which reflected in decreased average per capita water. The main objective of this study was to study the efficiency of water use in the production units, estimate the cash yield of the water unit and finally study the factors that affect them. Materials and Methods: Data were analyzed using Statistical Package for Social Sciences (SPSS) version 16. Quantitative data were presented as Means±SD. The independent sampleANOVA was used with two-way analysis of variance, with Post-hoc (LSD) test was used to analyze mean difference. Probability values (P) of less than 0.05 were regarded as statistically significant. Results: The most important results of the study suggested to the low average per capita average annual attrition rate of about 1.29% and rising share of water resources industry with a growth rate of approximately 15.1% during the study period have been measuring the significance differences between the sample in the water-use efficiency, proven statistical model significant at level p<0.05. Also, suggest the disparity in the percentage of the cost of employing and run water to an average of about 5% of total operating costs, as well as indicate low efficiency rate. Conclusion: The study concluded that a clear plan Inspection Department on how to deal with these facilities over the long term and anaerobic biological treatment in processing the high organic content industrial pollutants.
