Special Issue Information
Dear Colleagues,
With the acceleration of urbanization and the continuous advancement of industrialization and agricultural modernization, more pollutants are entering the natural water environment, exerting a serious impact on water quality and ultimately endangering human health. Traditional wastewater treatment methods, such as physical sedimentation and chemical treatment, can remove pollutants to a certain extent; however, they are associated with problems such as high energy consumption, high operating costs, intensive CO2 emission, and secondary pollution. Therefore, the research and development of new and effective treatment technologies have become an important task. Due to its high efficiency, environmental protection, and low economic cost, microbial treatment technology has gradually attracted the attention of researchers and has become a promising solution to wastewater treatment problems.
The microbial treatment of wastewater utilizes microorganisms to convert organic matter, nitrogen, phosphorus and other pollutants in wastewater into biomass with high-value components, thereby generating both ecological and economic benefits. In real-world applications, the metabolic activity and treatment capacity of microorganisms can be enhanced by optimizing the culture conditions. At present, microbial treatment is successfully utilized for the remediation of aquaculture wastewater, piggery wastewater, industry wastewater, pharmaceutical wastewater, municipal wastewater and so on. In addition, due to the government's strict regulations on wastewater discharge, the market of microbial wastewater treatment is rapidly growing. In particular, the economic value of the microbial biomass obtained from wastewater treatment could enhance the profits of wastewater treatment plants. Therefore, the microbial treatment of wastewater exhibits promise in the agriculture, aquaculture and industry.
The scope of this Special Issue includes, but is not limited to, the following topics:
- The practical application of the microbial treatment of wastewater for the development of sustainable agriculture, aquaculture and industry;
- The effect of the wastewater environment on the metabolism of microorganisms and the biosynthesis of microbial components;
- Innovative technologies for microorganism cultivation and high-value biomass production in wastewater;
- The valorization of the microbial biomass obtained from wastewater treatment in animal feed, fertilizer, and biofuel;
- Future trends and challenges in the application of microbial technologies for wastewater treatment;
- The contribution of new technologies (e.g. artificial intelligence) to the development of the microbial treatment of wastewater.
