食品工业污水处理

Abstract The purpose of the present study is to assess the condition of wastewaters pertaining to the production of cooking oil and to develop an effective and low-cost method for purification of wastewaters and utilisation of other oil production-related wastes which would comply with environmental safety requirements. It was made a quality assessment in terms of content of polluting substances of cooking oil-production wastewater. For identification of fat content (phospholipids) of wastewaters, the thin-layer chromatography method was applied. The basis of the proposed method for purification of wastewaters was a preliminary separation of clarified and neutralized wastewater by dint of calcium carbonate, subsequently sodium hypochlorite for water clarification and its additional neutralization was used. The presented method allows reaching a high degree of wastewater purification, being effective and low-cost. 摘要 本研究的目的是评估生产食用油污水的情况和制定一个有效的、低成本的净化方法，在遵守环保安全要求的情况下利用其他含油污水和含油废弃物，旨在按照质量来评价烹调产生的油类污水。其中薄层色谱法应用于识别脂肪含量(磷脂)的污水。在该方法的基础上，对污水的净化是一个初步澄清分离污水中的碳酸钙，随后用次氯酸钠澄清水，再添加中和剂的过程。本文所提出的方法可以达到一个高度净化污水的目的，具有高效、低成本的特点。 Keywords: Cooking oil production wastewater; phospholipids; thin-layer chromatography; wastewater purification; wastewater treatment

One of the main tendencies of development of food industry in the 21st century is the creation of useful and healthy products, the so-called functional food products. A specific feature of such products is that they contain ingredients which, besides their traditional nutrient and energys upplying function, also possess a range of specific physiological functions which help human organism to combat negative influence of civilisation. 创造这种有用的、健康的叫做功能性食品的产品在二十一世纪成为一种食品工业上的主要发展趋势。这种产品的特征是包含了某些材料，除了具有提供传统养分和能量的功能，还具有一系列独特的生理功能，有助于人体对抗负面影响。

Food industry is one of the most resource-demanding branches of industry, therefore it is especially important to ensure rational usage of raw materials. In the processing sub-branches of agricultural complex where the net value of products is comprised of material and energy expenditures, it is increasingly crucial to decrease the consumption of materials. This can be achieved by dint of wide implementation of non-waste technologies, complex usage of raw materials and secondary(recycled) resources in combined industry. Another important aspect of the subject problem is ensuring of ecological safety of plants where the food products are produced as well as elimination of the influence of the wastes upon the environment. One of the most important problems which the food industry enterprises face is the problem of wastewater treatment. In Ukraine, food-producing enterprises are mostly located in the West and the South-West which have a rich network of water bodies. This means that
