Inside the unit, wastewater undergoes biological treatment, decolorization, deodorization, disinfection and reverse osmosis (RO) membrane filtration. Under the designed operating conditions, the system achieves a water reuse rate of ≥95%, reducing the need for fresh water and routine wastewater removal.
The modular, insulated enclosure can be installed and relocated by crane, without underground sewer construction or a conventional septic tank. Installation takes approximately 2 hours, subject to site preparation and utility access. A single-stall configuration is designed for approximately 60–80 uses per day, while multi-stall configurations can accommodate approximately 300–1,500 uses per day.
With an operating temperature range of -30°C to 60°C, the system is designed for public facilities in urban pedestrian streets, commercial districts, cultural tourism areas, city squares and other locations where conventional sewer infrastructure is difficult or costly to install.
The wastewater treatment system is integrated into the toilet enclosure, so wastewater can be treated on-site rather than conveyed to an external municipal sewer network.
After use, wastewater enters the primary crushing and equalization tank before being pumped through the biological treatment stages. The wastewater then passes through decolorization, deodorization and disinfection, followed by RO membrane filtration. The treated water is collected in a clean-water tank and reused for toilet flushing.
This integrated process reduces dependence on external wastewater infrastructure and supports water recycling in public spaces where underground drainage construction is impractical.
Toilet bowl → Primary crushing and equalization tank → Variable-frequency sewage pump → Anaerobic biological tank → Anoxic tank → Aerobic biological tank → Decolorization, deodorization and disinfection tank → RO membrane filtration → Clean-water tank → Toilet flushing
The system uses a composite microbial consortium to break down organic matter in toilet wastewater. The stated organic matter degradation rate is up to 99%, with microbial activity maintained for more than six months under suitable operating conditions.
This biological treatment stage helps reduce the organic load before the wastewater proceeds to subsequent treatment and filtration stages.
Wastewater passes through anaerobic, anoxic and aerobic biological treatment stages, followed by decolorization, deodorization, disinfection and reverse osmosis membrane filtration.
The specified treatment cycle is 48–72 hours, with a filtration precision of 0.01 μm and a water reuse rate of ≥95%. The treated water is returned to the clean-water tank for toilet flushing, supporting an internal water recycling process.
The system supports remote monitoring of water quality, ammonia, hydrogen sulfide, temperature and humidity. Operating parameters can be adjusted according to usage levels, and the control system can provide fault alerts when abnormalities are detected.
These functions help operators monitor equipment status and identify operating issues without relying entirely on routine on-site checks.
The toilet uses a double-layer insulated enclosure with an IP65 protection rating and a specified operating temperature range of -30°C to 60°C. Its design life is more than 10 years.
The integrated structure combines the toilet facilities and wastewater treatment equipment in one unit, simplifying installation and allowing the complete unit to be relocated when public-space layouts or project requirements change.

The Jingjiu Mobile Eco Toilet features an integrated containerized structure designed to simplify on-site installation. After delivery, the main preparation requirements are a level installation surface, a suitable power connection and approximately 10 m³ of initial water for system start-up.
Unlike conventional public toilets that depend on underground sewer networks and traditional septic tanks, the unit integrates wastewater treatment and flushing-water reuse within the enclosure. This reduces the need for extensive underground construction and helps shorten site preparation time.
The complete unit can be lifted by crane for installation or relocation. If a pedestrian street is renovated, a commercial district is reconfigured or a tourist area changes its public facility layout, the toilet can be moved to another suitable location instead of being rebuilt from the ground up.
Actual installation time depends on lifting arrangements, site access, ground preparation and utility connections.
Pedestrian streets and commercial blocks often need additional public toilets without major disruption to existing roads, paving or underground utilities. The containerized design allows single-stall or multi-stall configurations to be selected according to expected foot traffic and available space.
The integrated wastewater treatment system is particularly relevant to locations where connecting a new public toilet to the municipal sewer network would involve extensive construction.
Tourist streets, scenic areas and visitor service zones can experience significant changes in toilet demand between weekdays, weekends and peak travel periods. A relocatable toilet unit provides an option for adding sanitation capacity without permanently changing the surrounding site layout.
The required number of stalls can be selected according to visitor volume, site space and project requirements.
City squares, parks and public event spaces may require additional sanitation facilities during festivals, outdoor activities and periods of increased visitor traffic. The unit can be installed as a standalone facility or configured with multiple stalls to suit the intended service capacity.
Its integrated structure also provides flexibility when public-space planning or facility locations change.
The same mobile sanitation approach can also be considered for gas stations, large construction sites, military field training areas, emergency accommodation sites and space-launch support facilities, subject to project-specific technical and operating requirements.
Jingjiu's mobile eco toilets have been used in projects associated with China National Petroleum Corporation (CNPC) and China Petroleum & Chemical Corporation (Sinopec). The company reports experience across more than 50 projects, with some installations operating continuously for over three years.
For a space-launch support project, the equipment reportedly operated under conditions involving temperatures of 45°C, relative humidity of 90% and a sudden threefold increase in load, supporting the project's sanitation requirements.
The company's products have also been deployed at engineering sites, rural towns, tourist attractions, gas stations and military facilities. Jingjiu reports cumulative deliveries of more than 1,000 units across its application sectors.
Project-specific operating records, reference details and test documentation can be provided where available and authorized for disclosure.
The estimated annual operation and maintenance cost of the Jingjiu Mobile Eco Toilet is approximately RMB 15,000–20,000. Compared with the stated annual fecal sludge pumping cost of RMB 120,000–150,000 for a conventional public toilet, the integrated system may reduce expenditure associated with routine waste removal.
The main difference is that the mobile eco toilet treats wastewater within the unit and reuses the treated water for flushing, reducing dependence on external wastewater collection and disposal services. A conventional public toilet may require regular fecal sludge pumping, depending on its storage capacity, wastewater arrangements and usage levels.
Actual savings depend on local labor and electricity rates, daily visitor numbers, water consumption, maintenance requirements, waste disposal charges and the configuration of the existing facility. The figures below should therefore be treated as indicative cost estimates rather than guaranteed savings.

No. The wastewater treatment system is integrated into the unit, and treated water is reused for toilet flushing. A municipal sewer connection is not required for the designed operating process.
Routine fecal sludge pumping is not required under normal designed operating conditions. The system uses composite microorganisms to degrade organic matter, followed by additional treatment and RO membrane filtration. Actual maintenance and residual waste handling requirements should be confirmed for the selected configuration and operating conditions.
The specified operating temperature range is -30°C to 60°C, and the enclosure uses a double-layer insulation structure. For projects exposed to prolonged freezing conditions, confirm the required insulation, heating, water-system protection and winter operating arrangements before installation.
Installation takes approximately 2 hours under suitable site conditions. Preparation generally includes leveling the installation surface, connecting the power supply and providing approximately 10 m³ of initial water for system start-up. Crane access and site readiness can affect the actual installation time.
Yes. The integrated containerized unit can be lifted by crane and moved as a complete unit. Relocation arrangements depend on the lifting points, transport requirements, site access and reconnection of utilities.
A single-stall configuration is designed for approximately 60–80 uses per day. Multi-stall configurations can accommodate approximately 300–1,500 uses per day, depending on the selected design and actual usage patterns.
The designed process returns treated water to the clean-water tank for toilet flushing, forming an internal water recycling loop. The stated water reuse rate is ≥95%. Whether a particular installation can be described as zero discharge must be confirmed against its complete water balance, residual waste handling arrangements and applicable project requirements.
The estimated annual operation and maintenance cost is approximately RMB 15,000–20,000. Actual costs depend on electricity consumption, usage levels, maintenance needs, local labor costs and the selected configuration.
The unit can be configured with different numbers of stalls according to expected daily usage and available space. For a specific project, provide the installation location, expected visitor volume, available site dimensions, power supply and local climate conditions so that the appropriate configuration can be evaluated.
