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。
