This open access publication presents a comprehensive treatment method for rural domestic sewage, and emphasizes ten representative cases in China. The integrated sewage treatment system (ISTE) integrates sewage pretreatment, biological treatment, sedimentation, and disinfection. It is especially useful for decentralized domestic wastewater treatment in rural locations without pipe networks. ISTE has several key benefits, including its streamlined design, minimal space requirements, quick installation timeline, effective treatment capabilities, and cost-effectiveness.
