Solar Wastewater Treatment Plant

Introduction to Solar Wastewater Treatment Plant

The solar wastewater treatment plant combines advanced solar photovoltaic power generation technology and sewage treatment technology, uses renewable energy to drive the purification of domestic sewage, and promotes efficient use of resources and sustainable development of the environment.

Composition of Solar Wastewater Treatment Plant

The solar wastewater treatment plant is a multifunctional environmental protection system with the following core components:

1. Solar photovoltaic panels: As the energy supply core of the system, it converts solar energy into electrical energy to meet the energy needs of sewage treatment facilities.

2. Battery pack: Stores the electricity generated by photovoltaic panels to ensure that the system can continue to operate under no light conditions.

3. Control system: Adopts microcomputer control and remote communication technology to automatically monitor and manage the sewage treatment process, including adjusting aeration time, return ratio, and monitoring plant status to achieve energy-saving and efficient operation.

4. Aeration system: Oxygen is injected into the treatment pool through an electric aeration device to promote the activity of aerobic microorganisms and the biodegradation of organic matter.

5. Return system: Through the set ratio, part of the treated water is returned to the front end of the system to maintain the activity of the microbial community and stable treatment efficiency.

6. Biological treatment unit: including anaerobic tanks, aerobic tanks (such as biological contact oxidation tanks) and sedimentation tanks, etc. These units remove pollutants such as organic matter, ammonia nitrogen and nitrite in water through the metabolism of microorganisms.

7. Filtration unit: such as sand filter or membrane filtration system, further removes suspended matter and some dissolved organic matter in water to improve the quality of effluent.

8. Disinfection unit: using ultraviolet rays, ozone or chemical agents for disinfection, killing bacteria and viruses in water to ensure the safety of effluent.

9. Structural components: including the shell, support structure, pipelines and valves of the plant, usually designed as buried or above-ground type, aiming to save space and improve the beauty of the environment.

10. Safety and monitoring plant: such as level gauges, pressure gauges and water quality monitoring instruments, real-time monitoring of plant operation status to ensure safety and water quality.

Features of solar wastewater treatment plant

• Energy saving and high efficiency: using solar energy to reduce power consumption and reduce operating costs.
• Environmentally friendly: Reduce greenhouse gas emissions, avoid secondary pollution, and comply with the green and low-carbon principles.
• Automated operation: Automatically adjust the treatment process to minimize human intervention.
• Small footprint, integrated design: Easy to install and maintain, suitable for occasions with limited space.
• Convenient maintenance: Modular design simplifies filter material replacement and system maintenance.
• Wide adaptability: Suitable for domestic sewage treatment needs of various sizes, such as decentralized residences, rural areas, resorts and small towns.

Application areas of solar wastewater treatment plants

The plant is particularly suitable for areas far away from the power grid and with unstable power supply, as well as communities, residential areas and tourist attractions that pursue green and low-carbon life. It is an ideal solution to solve the problem of domestic sewage treatment in remote areas, and an important technical equipment to promote ecological civilization construction and environmental protection.

1. Collection and pretreatment: First collect domestic sewage, after simple pretreatment such as grating and precipitation, remove large particles and impurities.

2. Solar power supply: The solar photovoltaic panel built into the system converts solar energy into electricity, which is stored in the battery for the entire sewage treatment system, including mixing, aeration, pumping and other energy-consuming links.

3. Biochemical treatment: The core treatment part usually adopts biological treatment technology, such as activated sludge method, biofilm method (such as MBR membrane bioreactor) or anaerobic-aerobic (A/O) process, which uses microorganisms to decompose organic matter in sewage and remove nutrients such as nitrogen and phosphorus.

4. Deep purification: The water after biochemical treatment is further removed by sand filtration, activated carbon filtration or membrane filtration and other advanced treatment technologies to further remove fine suspended matter and some dissolved organic matter and improve the effluent quality.

5. Disinfection: Finally, pathogens in the water are killed by ultraviolet disinfection, ozone or chemical disinfectants to ensure the safety of the water.

6. Reuse or discharge: The treated water can be directly used for flushing, irrigation and other non-drinking purposes, or discharged to natural water bodies, in line with local environmental discharge standards.

1. Pretreatment: Remove large particles and impurities from the water by physical methods such as grating and precipitation.

2. Biochemical treatment: The use of activated sludge method, biofilm method, etc., through microbial action to remove organic matter, nitrogen and phosphorus and other pollutants.

3. Advanced treatment: It may include sand filtration, membrane filtration and other steps to further remove fine suspended matter and some dissolved substances to improve water quality.

4. Disinfection: In the final stage, ultraviolet light or chlorination are usually used to kill bacteria and viruses in the water to ensure the safety of the water.
