食品工业节水技术研究与展望

Recent Advance in Water Saving Technology of Food Industry

目前水资源严重短缺。食品工业作为耗水大户,在节水工艺的开发和水资源回收利用方面潜力巨大,然而由于法规制度不健全以及安全性等问题,因此实现水回用充满挑战。本文介绍食品工业节水技术及水回用的基本概念,总结用水存在的问题;介绍包括饮料工业、保藏工业、乳品工业等食品领域的水回用实践现状,以及水回用技术的研究进展。在此基础上,展望食品工业的水回用前景,提出食品工业节水技术或水回用工艺的未来研究和开发方向。

Water resource shorting is increasingly noticed in the world due to the limitation of the resource. Food industry, as one of the industry consumptions largest amount of water, holds great potential in developing water saving and recycling technology. However, recovery water from food industry still has great challenges due to incompletion of the laws and the limited technology specifically to treat food waster food. The present reviews summaries the principals ＇ of water recovery and recycling technology for food industry, as well as the current challenges in reuse of food waste water.Moreover, the recent advance of reuse water in specific disciplines, such as beverage, food preservation, dairy as well as other food industries were reviewed. Furthermore, future direction for technology of food waste water saving and recycling and complete of the laws were also suggested, and the prospect of water reuse in food industry were proposed.
