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 本研究的目的是評(píng)估生產(chǎn)食用油污水的情況和制定一個(gè)有效的、低成本的凈化方法，在遵守環(huán)保安全要求的情況下利用其他含油污水和含油廢棄物，旨在按照質(zhì)量來評(píng)價(jià)烹調(diào)產(chǎn)生的油類污水。其中薄層色譜法應(yīng)用于識(shí)別脂肪含量(磷脂)的污水。在該方法的基礎(chǔ)上，對污水的凈化是一個(gè)初步澄清分離污水中的碳酸鈣，隨后用次氯酸鈉澄清水，再添加中和劑的過程。本文所提出的方法可以達(dá)到一個(gè)高度凈化污水的目的，具有高效、低成本的特點(diǎn)。
