Abstract

Milk-based products are essential to the human diet, with India contributing 23% of global milk production. Dairy industries generate large amounts of waste, including solid and liquid waste, which are treated using wetland, biological, and physico-chemical methods. In India, dairy sludge is effectively managed by converting it into fertilizers. If industrial solid and liquid dairy waste is not managed correctly, it will increase pollution and harm biodiversity. If the sludge is properly managed, there is potential to transform it into various value-added products, including biofuels, biomass, biofertilizers, bricks, struvite, fertilizer, etc. Consequently, this technical review’s focal topic includes information on dairy operations’ wastewater treatment methods, the viability of microalgal cultures in wastewater, dairy sludge management, the range of biological product recovery, and its impact on the environment.

工业乳制品废水和污泥的补救和管理技术：综述

以牛奶为基础的产品是人类饮食的必需品，印度的牛奶产量占全球产量的 23%。乳制品行业产生大量废物，包括固体和液体废物，这些废物通过湿地、生物和物理化学方法进行处理。在印度，乳业污泥通过转化为肥料得到有效管理。如果奶制品工业固体和液体废物管理不当，将会增加污染，损害生物多样性。如果对污泥进行适当管理，就有可能将其转化为各种增值产品，包括生物燃料、生物质、生物肥料、砖块、硬石膏、肥料等。因此，本技术综述的重点主题包括乳品企业的废水处理方法、废水中微藻培养的可行性、乳品污泥管理、生物产品回收范围及其对环境的影响等方面的信息。

期刊介绍： The Journal of Material Cycles and Waste Management has a twofold focus: research in technical, political, and environmental problems of material cycles and waste management; and information that contributes to the development of an interdisciplinary science of material cycles and waste management. Its aim is to develop solutions and prescriptions for material cycles. The journal publishes original articles, reviews, and invited papers from a wide range of disciplines related to material cycles and waste management. The journal is published in cooperation with the Japan Society of Material Cycles and Waste Management (JSMCWM) and the Korea Society of Waste Management (KSWM).
