Overview of Rural Integrated Processing Equipment

Rural integrated treatment equipment usually refers to rural integrated sewage treatment equipment, which is an integrated equipment designed specifically for rural domestic sewage treatment. Here is the relevant introduction:
Definition and Characteristics
Integrated design: Integrating multiple processing units such as pretreatment, biological treatment, sedimentation, disinfection, etc. into one or several boxes to form a compact modular structure with a small footprint, suitable for rural land scarce environments.
Strong flexibility: Different process combinations, such as A/O, MBR, MBBR, etc., can be selected according to the processing scale (5-500 tons/day) and water quality requirements, to adapt to the characteristics of dispersed rural sewage and large fluctuations in water quantity and quality.
High degree of automation: Equipped with a PLC control system, it can achieve automatic operation, remote monitoring, and fault alarm, with easy operation and low requirements for professional skills of operation and maintenance personnel.
Environmentally friendly: It can be installed underground or semi underground, and the surface can be greened or used for other purposes to reduce the impact on the surrounding environment. At the same time, it effectively treats sewage and prevents water and soil pollution.
Process Principle
Pre treatment stage: intercepting large suspended particles through a grid, regulating the balance of water quality and quantity in the tank, removing inorganic particles such as sand particles in the sedimentation tank, and creating stable conditions for subsequent treatment.
Biological treatment stage: The core adopts biofilm method or activated sludge method, such as A/O process, which achieves nitrogen and phosphorus removal and organic matter degradation through anaerobic aerobic alternation; MBR process combined with membrane separation technology improves effluent quality and treatment efficiency.
Deep processing stage: Through disinfection (UV, sodium hypochlorite, etc.), filtration (sand filtration, activated carbon adsorption) and other processes, residual pollutants are further removed to ensure that the effluent meets the standard.
Sludge treatment: The remaining sludge is concentrated and dehydrated to form a sludge cake for external transportation, and some sludge is returned to the biological treatment unit to maintain microbial concentration.
Applicable scenarios
Rural residential areas: suitable for domestic sewage treatment in single household, multi household, or small natural villages, solving the problem of scattered discharge of sewage.
Township community: As an independent sewage treatment facility in towns, resorts, schools, and other places that are not connected to the municipal pipeline network.
Agricultural irrigation and reuse: The treated reclaimed water can be used for farmland irrigation, landscape water replenishment, etc., achieving water resource recycling.
Strengths and Limitations
Advantages: Short construction period, easy operation and maintenance, strong ability to withstand impact loads, can effectively improve rural water environment, and promote resource recycling.
Limitations: Low temperatures in winter may affect biological activity, membrane components require regular maintenance, and the processing capacity of a single device is limited, making it suitable for small and medium-sized wastewater treatment.
Equipment structure
Shell: Generally made of fiberglass reinforced plastic (FRP) or carbon steel anti-corrosion material, can be buried underground, saves surface space, and has good insulation performance.
Internal functional areas: usually designed with compartmentalization, including regulating areas, anaerobic areas, anoxic areas, aerobic areas, sedimentation areas, disinfection areas, and sludge storage areas.
Aeration system: A microporous aerator is installed at the bottom of the aerobic zone, supplied with oxygen by a Roots blower placed in the above ground equipment room.
Control system: Automated control cabinet, capable of automatically operating fans, lifting pumps, disinfection equipment, and equipped with fault alarm function, supporting remote monitoring through mobile APP.
Supporting facilities: including equipment foundation, inlet and outlet water pipe network, inspection well, equipment room, etc.
