Core Working Principle
The solar micro-power sewage treatment equipment adopts an innovative model of "solar power supply + biological treatment technology" to achieve efficient sewage purification.
Solar Energy Supply System：Solar energy is converted into electrical energy by photovoltaic modules and stored in batteries, providing continuous power for dynamic units such as aeration, stirring, and lifting. It eliminates the need for external power grids, completely breaking away from traditional equipment's reliance on municipal power.
Biological Treatment Process: Integrating AO (Anaerobic-Aerobic) process or MBR (Membrane Bioreactor) process, it utilizes microorganisms to degrade pollutants such as organic matter, nitrogen, and phosphorus in sewage.
Anaerobic Tank: Anaerobic bacteria decompose macromolecular organic matter to reduce the COD (Chemical Oxygen Demand) of sewage, while performing denitrification for nitrogen removal.
Aerobic Tank: The aeration system supplies sufficient oxygen, allowing aerobic microorganisms to further decompose pollutants, achieving nitrification of ammonia nitrogen and deep degradation of organic matter.
Sedimentation: Sludge is separated from clear water through sedimentation to ensure that the effluent quality meets the discharge standards.
Intelligent Control System: Integrated with a PLC automatic control system, it can adjust operating parameters in real time according to water quality (such as aeration volume and hydraulic retention time), enabling intelligent switching between "energy-saving mode" and "high-efficiency treatment".
Structural Features
Integrated Design
Compact modularization: Integrating solar energy systems, biochemical treatment units, and electrical control systems into an integrated device, with a floor area of only 1/3 to 1/2 of traditional processes. It can be installed underground or above ground, adapting to space-constrained scenarios such as rural areas and scenic spots.
Anti-corrosion and durable: The main body of the equipment is made of carbon steel anti-corrosion or stainless steel materials, resistant to acid and alkali corrosion, and the service life can reach more than 15 years.
Advantages of Solar Energy Systems
Zero electricity cost operation: The photovoltaic modules can generate 2-10 kWh of electricity per day (adjusted according to sunshine duration), meeting the 24-hour low-power operation of the equipment and saving more than 10,000 yuan in electricity bills annually.
Energy storage guarantee: Equipped with maintenance-free batteries, which can maintain the normal operation of the equipment for 3-5 days under continuous rainy and cloudy weather.
Intelligent Operation and Maintenance (Intelligent O&M)
Remote monitoring: Support real-time monitoring of water quality data (such as COD, ammonia nitrogen, pH value) and equipment operation status (such as power, aeration frequency) through mobile APP or cloud platform. It has automatic fault alarm function, which reduces the cost of manual inspection.
