FOOD INDUSTRY WASTEWATER TREATMENT

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

control over discharge of sewage water is to be exercised more strictly than usual and food-producing companies in these regions are to be prevented from polluting the water reservoirs.

食品企业是对资源要求最高的产业结构之一，因此确保原材料的合理使用显得尤为重要。农业加工行业的净价值由原材料和能量支出决定，而且越来越多的决定于原材料的消耗。这就可以实现无废物生产技术、反复使用的原材料技术和使用二次(再生)资源技术的联合工业。食品工厂在产品生产和去除环境中废物的过程中的主要问题的另一个重要方面是确保生态安全。其中一个最重要的问题是企业面临的食品工业污水处理的问题。在乌克兰, 食品生产企业主要分布在有丰富水体网络的西部和西南部。这意味着控制排放的污水要比平时更严格地执行来避免食品生产公司在这些地区污染水库。

Ukraine is one of the five main world producers of sunflower. Yearly output of sunflower amounted to more than 4 million tonnes in this year. Only Argentine (6.4 m tonnes) produced more.

乌克兰是世界五个主要向日葵生产地之一。今年向日葵的年产量达400万多吨。比阿根廷(6.4万吨)所产生的多得多。

In the latest years, Ukrainian vegetable oil market has become increasingly more integrated into the global vegetable oil market. This is due to the fact that processes of international division of labour get deepened and Ukraine is becoming one of the world’s leading producers of sunflower seeds, sunflower oil, and groats.

最近几年，乌克兰的植物油市场日益融入全球植物油市场。这是由于这样的事实，乌克兰在国际分工的过程中得到深化，已经成为世界领先的向日葵花种子、向日葵花油和燕麦的生产地。 Therefore, we are facing a crucially important task which foresees a more detailed examination of peculiarities of such valuable product as sunflower oil, bringing this production closer to the ecologically clean technologies whilst minimising the wastes of production.

因此,我们正在面临着一个重要的任务, 更详尽地预测如此有价值的向日葵花油的产品特性，促进清洁生产同时减少产生的废料。

Sunflower oil, alongside other vegetable oils, possesses a number of useful properties which make its consumption a lot more preferable than consumption of animal fat. 向日葵花油与其他植物油一样，拥有许多有益的特性，比很多动物脂肪消耗的更多。

With the purpose of further study of ecological influence of production of the cooking oil, assessment of the condition of sewage water, we shall examine the technology of oil production.

我们进一步对生产食用油产生的生态影响的研究是为了评估污水情况,检查技术食用油的生产工艺。
