Hongqiao Environmental Protection Mobile Toilet
The Hongqiao environmental protection mobile toilet is a mobile sanitation facility that employs microbial decomposition technology, featuring efficient resource recycling and eco-friendly treatment capabilities. Its core features and advantages can be elaborated as follows:
1. Microbial Decomposition Technology
This type of toilet utilizes specific microbial communities screened from nature to biologically degrade excreta. Microorganisms exhibit optimal activity within a temperature range of 20-40 degrees Celsius and a pH range of 6.5-7.5, converting organic matter into water and carbon dioxide, significantly reducing the volume of solid waste. Rental companies dynamically adjust the microbial dosing cycle based on usage frequency (e.g., daily user count) to ensure treatment efficiency. For instance, in high-frequency usage scenarios, microbial solution may need to be replenished daily, while in low-frequency scenarios, the interval can be extended to 3-5 days.
2. Resource Recycling System
The equipment employs a dual-channel drainage design: gray water (a mixture of urine and cleaning water) is initially filtered and then directly used for toilet flushing, forming a closed-loop cycle; black water (solid waste) enters the microbial treatment chamber, where an built-in pump station elevates the treated gray water to an elevated storage tank to maintain stable flushing pressure. This system can reduce freshwater consumption by 60%-80%, making it particularly suitable for water-scarce regions or large-scale event settings.
3. Odor Control and Ventilation
A negative pressure ventilation system continuously extracts internal air through a small fan at the top, maintaining lower air pressure inside the toilet than the external environment, effectively preventing odor leakage. The extracted air passes through an activated carbon filter to adsorb odor molecules such as ammonia and hydrogen sulfide, with the filter replacement cycle ranging from 3-6 months (adjusted based on usage intensity). Some premium models are additionally equipped with ozone generators, which further decompose residual odor molecules through oxidation reactions, achieving a nearly odor-free user experience.
4. Energy Supply Solutions
The system primarily relies on solar photovoltaic panels and deep-cycle battery packs: during the day, the photovoltaic panels directly power the equipment and charge the batteries, while at night or on cloudy days, the batteries provide electricity. The battery capacity is typically configured at 500-800 watt-hours per day, sufficient to meet basic lighting, fan, and pump station operational needs. In regions with insufficient sunlight (e.g., northern areas in winter), rental companies will provide backup diesel generators or adjust the battery pack capacity to ensure 24-hour continuous operation.
5. Modular Transportation and Installation
Before transportation, the equipment is disassembled into three independent units: the treatment chamber (including the microbial tank), the water storage module (including the circulation pump), and the toilet module, facilitating truck transportation. During installation, the base must be secured to prevent tipping, and after connecting the water pipes and electrical circuits, the microbial solution is filled, with the entire process taking approximately 2-4 hours to complete. Special attention must be paid to the sealing of pipe connections to avoid bending that could obstruct drainage.
Regarding rental services, services can be obtained in Hongqiao District, Tianjin through Haoshitong Pipeline Engineering (phone: 15822042458), covering scenarios such as marathons, concerts, and construction sites, supporting both short-term rentals and long-term collaborations.
