Within the scope of this article, the author proposes a suitable surface water treatment technology chain for concentrated rural areas: Static mixing device - Self - cleaning contact flocculation filter tank - Gravity filter tank - Ozone disinfection, aiming to replace the cluster of tanks (Mixing - Reaction - Settling) in the water treatment technology chain with a cluster (Static mixing device - self-cleaning contact flocculation floating media filter tank), reducing construction area, enhancing posttreatment water quality, lowering operation and management costs, ensuring safe water quality that aligns with the operating staff's expertise. This is applicable to small and medium-sized concentrated rural surface water treatment stations. Keyword: Appropriate technology
