厌氧发酵作为城乡有机废弃物资源化利用的关键技术,广泛应用于农业、工业及市政领域,有效促进了减污降碳目标的实现。然而,传统中温和高温发酵之间的过渡区域,即40-45℃温度区间,因有机物去除负荷和产气率较低,被业界视为“低速厌氧发酵区”。杭能环境通过长期的工程实践与科学研究,颠覆了这一传统认知。

在维尔利集团的支持下,杭能环境聚焦中温至高温过渡区的厌氧发酵,经过系列机理研究和技术创新,开发出了“中高温”厌氧发酵技术。这一技术通过精确的温度控制和优化的进料布水策略,创造了一个适宜“中高温”厌氧微生物生长的微环境,成功驯化了一种高效稳定的产甲烷微生物菌群。实验结果表明,“中高温”厌氧技术不仅显著提升了产甲烷效率,还增强了系统对抗冲击负荷的能力,确保了沼气工程的长效稳定性,从而实现了沼气工程的提质增效。

此次技术突破不仅获得了国家发明专利授权,更进一步取得了PCT美国专利授权,彰显了杭能环境在厌氧发酵领域的国际领先地位。此外,由杭能环境主导,联合浙江大学、农业农村部农业生态与资源保护总站、中国农业大学等多家权威机构共同参与制定的《中高温沼气工程技术指南》农业行业标准送审稿,已于6月25日顺利通过全国沼气标准化技术委员会审定,为行业规范化发展提供了重要指导。

As a key technology for resource utilization of organic waste in urban and rural areas, anaerobic fermentation is widely used in agriculture, industry and municipal fields, and effectively promotes the realization of pollution reduction and carbon reduction goals. However, the transition area between the traditional mild and high-temperature fermentation, that is, the temperature range of 40-45 ° C, is regarded as a "low-speed anaerobic fermentation area" by the industry because of the low organic matter removal load and gas production rate. Hangneng Environment subverts this traditional understanding through long-term engineering practice and scientific research.

With the support of Welly Group, Hangneng Environment focuses on anaerobic fermentation in the transition zone from medium temperature to high temperature, and has developed the "medium and high temperature" anaerobic fermentation technology through a series of mechanism research and technological innovation. This technology successfully domesticated an efficient and stable methanogenic microbial community by creating a microenvironment suitable for the growth of "medium and high temperature" anaerobic microorganisms through precise temperature control and optimized water feeding strategy. The experimental results show that the "medium-high temperature" anaerobic technology not only significantly improves the methane production efficiency, but also enhances the system's ability to resist the impact load, ensures the long-term stability of the biogas project, and thus realizes the quality and efficiency improvement of the biogas project.

This technological breakthrough not only obtained the national invention patent authorization, but also obtained the PCT patent authorization in the United States, demonstrating the international leading position of Hangeng Environment in the field of anaerobic fermentation. In addition, led by Hangneng Environment, and jointly developed by Zhejiang University, the Ministry of Agriculture and Rural Agriculture and Resources Protection Station, China Agricultural University and other authoritative institutions, the "medium and high temperature biogas Engineering Technical Guide" agricultural industry standard submission draft, has been successfully approved by the national Biogas standardization Technical Committee on June 25, providing important guidance for the standardized development of the industry.
