Abstract

Because of the low energy consumption of aeration, strong nutrient removal capacity, low greenhouse gas emissions and high resource recovery potential, the wastewater treatment process using microalgal–bacterial consortia is considered as an excellent alternative to the traditional activated sludge wastewater treatment process. In this review, the wastewater treatment process based on microalgal–bacterial consortia and its greenhouse gas emission reduction mechanism are introduced. The potential advantages and constraints of the process in carbon neutral wastewater treatment were highlighted and critically discussed. The environmental impact of wastewater treatment, the research progress of environment‐friendly treatment technologies and the challenges faced by integrating these technologies are discussed. However, the wastewater treatment process based on microalgae–bacteria consortia still needs to be studied. In the future, it is necessary to optimize the scheme for quantifying the environmental impact of wastewater treatment and further expand the recycling rate and cost value of wastewater resources.

可持续废水处理的进展:微藻-细菌联合体工艺、温室气体减排和能源回收技术

由于曝气能耗低、养分去除能力强、温室气体排放量低、资源回收潜力高，利用微藻-细菌群落的废水处理工艺被认为是传统活性污泥废水处理工艺的优秀替代方案。本文介绍了基于微藻-细菌群落的污水处理工艺及其温室气体减排机理。着重讨论了该工艺在碳中和的废水处理中的潜在优势和制约因素。讨论了废水处理对环境的影响、环保处理技术的研究进展以及整合这些技术所面临的挑战。然而，基于微藻-细菌群落的废水处理工艺仍有待研究。未来，有必要优化废水处理对环境影响的量化方案，进一步扩大废水资源的回收率和成本价值。

期刊介绍： Water and Environment Journal is an internationally recognised peer reviewed Journal for the dissemination of innovations and solutions focussed on enhancing water management best practice. Water and Environment Journal is available to over 12,000 institutions with a further 7,000 copies physically distributed to the Chartered Institution of Water and Environmental Management (CIWEM) membership, comprised of environment sector professionals based across the value chain (utilities, consultancy, technology suppliers, regulators, government and NGOs). As such, the journal provides a conduit between academics and practitioners. We therefore particularly encourage contributions focussed at the interface between academia and industry, which deliver industrially impactful applied research underpinned by scientific evidence. We are keen to attract papers on a broad range of subjects including: -Water and wastewater treatment for agricultural, municipal and industrial applications -Sludge treatment including processing, storage and management -Water recycling -Urban and stormwater management -Integrated water management strategies -Water infrastructure and distribution -Climate change mitigation including management of impacts on agriculture, urban areas and infrastructure
