Core Viewpoint - The "Small Garden" model provides an innovative solution for rural wastewater treatment, addressing challenges such as high costs and operational difficulties in traditional systems [1][2] Group 1: Cost-Effectiveness - The "Small Garden" model has a construction cost approximately 40% of that of centralized treatment systems, significantly lowering the economic barrier for rural areas to implement wastewater treatment [1] - This model is crucial for achieving comprehensive rural wastewater treatment and alleviating funding shortages [1] Group 2: Operational Simplicity - The "Small Garden" system requires minimal maintenance, with an annual maintenance cost of less than 10 yuan per household, making it suitable for areas with a lack of professional maintenance personnel [1] - The system occupies only about 6 square meters and operates without the need for electricity, further reducing operational burdens [1] Group 3: Resource Reutilization - The model transforms wastewater into usable resources, allowing treated water to be used for irrigation in nearby gardens and orchards, thus promoting ecological agriculture [2] - This approach aligns with the integration of ecology, production, and daily life in rural areas, enhancing community acceptance and participation in wastewater management [2]
