Technical principle
Energy supply: Solar energy is converted into electricity through
photovoltaic panels and stored in batteries to provide power for
the sewage treatment process (such as pumps, aeration devices, and
control systems), achieving "zero external grid connection"
operation.
Treatment process: Usually, a combined process of "pretreatment +
biological treatment + advanced treatment" is adopted, for example:
Pretreatment: Grid filtration and grit chamber to remove large
particle impurities;
Biological treatment: Degrading organic matter through
anaerobic/aerobic microorganisms (such as cooking oil and
detergents in hotel wastewater, and domestic pollutants in retail
wastewater);
Advanced treatment: membrane filtration, ultraviolet disinfection,
etc., to make the water quality meet the discharge standards or
reuse requirements.
Intelligent control: Integrated with a PLC control system, it
automatically adjusts the operation mode based on water quality and
quantity, and supports remote monitoring (such as checking the
equipment status via a mobile phone APP).
Environmental protection and energy conservation: In line with the
requirements of green operation
1.Zero carbon emissions: Relying on solar power supply, it can
reduce carbon emissions by tens of tons annually compared to
traditional electric equipment, which is in line with the hotel's
"carbon neutrality" promotion selling point (such as the ESG report
requirements of international brands).
Water resource recycling: The treated water quality can meet the
"Urban Sewage Reuse" standard and be reused for hotel toilet
flushing, landscape water replenishment, or irrigation of shopping
mall greenery, saving more than 30% of water consumption.
Case: After a resort hotel in a certain scenic area adopted
solar-powered sewage treatment equipment, the daily reuse of
reclaimed water reached 200 tons, saving approximately 150,000 yuan
in water fees annually. At the same time, it was awarded the "Green
Tourism Hotel" certification.
2. Flexibly adapt to the site and requirements
Small footprint and easy installation: The equipment mostly adopts
modular design (such as container type), occupying an area of only
10-50 square meters (equivalent to the area of 1-2 hotel rooms),
and can be installed underground or outdoors without affecting the
ground planning of the shopping mall.
Resistance to load fluctuations: In response to the sudden increase
in water volume during peak seasons in hotels (such as a doubling
of sewage discharge during holidays), the equipment can
intelligently adjust aeration time and sludge return ratio to
ensure stable treatment efficiency.
Suitable for areas without pipeline networks: such as suburban
shopping centers and highway service areas. There is no need to
wait for the municipal pipeline network to be laid. It can be
directly "installed and used immediately", shortening the
construction period by more than 50%.
3. Low operating costs: Significant long-term economic benefits
Zero electricity bill expenditure: Solar power supply covers over
90% of the energy consumption of equipment (such as aeration fans
and water pumps), and only a small amount of battery reserve power
is used on cloudy days, reducing the annual electricity cost by
90%.
Simple maintenance: High degree of automation, no need for
dedicated personnel to stand by (only one inspection per month is
required), reducing labor costs by 50% compared to traditional
sewage treatment stations. The core components such as membrane
modules have a lifespan of 5 to 8 years, and the replacement cost
is low.
Quick return on investment: Taking a hotel that processes 100 tons
of sewage per day as an example, the equipment investment is
approximately 150,000 to 200,000 yuan. Through water conservation,
electricity saving and government environmental protection
subsidies (with special support in some areas), the cost can be
recovered within 3 to 5 years.
4. Compliance and brand value enhancement
Standard discharge: The COD (Chemical Oxygen Demand) of the treated
water quality is ≤50mg/L, and the ammonia nitrogen is ≤5mg/L,
meeting the first-level A standard of the "Pollutant Discharge
Standard for Municipal Wastewater Treatment Plants", avoiding the
risk of environmental protection penalties.
Marketing highlights: The retail industry can use the equipment as
a promotional point for "green shopping malls" (such as displaying
the processing procedures and water quality data on the notice
board) to attract environmentally conscious consumers. Hotels can
include it in the room manual to enhance guests' favorable
experience.
5. Disaster resistance and continuous operation capacity
The advantage of independent power supply: When natural disasters
such as typhoons and heavy rain cause power grid failures, solar
equipment can still rely on batteries to maintain operation for 3
to 5 days, avoiding sewage overflow pollution (traditional
equipment stops running when power is cut off).
Low-temperature adaptability: Some equipment is equipped with a
solar heating system, which can still ensure the activity of
microorganisms in an environment of -10 ℃, making it suitable for
use in hotels in northern regions during winter.
