Heihe Mobile Toilet and Environmental Toilet
The environmental toilets in Heihe's mobile toilets focus on environmental protection technology, achieving resource recycling, pollution control, and public health protection through multi-dimensional design, especially suited to cold-region environments.
Environmental Protection Technology Applications: Full-Process Resource Treatment
Excrement treatment employs microbial degradation or chemical decomposition techniques. Microbial degradation tanks cultivate cold-resistant microbial communities that remain active in cold regions like Heihe, breaking down organic matter into water and carbon dioxide, avoiding chemical pollution from traditional toilets. The water recycling system converts hand-washing wastewater into flushing water through sedimentation, filtration, and UV/ozone disinfection, enabling 5-8 cycles of water reuse per supply and reducing freshwater consumption. Energy-saving design integrates photovoltaic panels for power supply, thermal insulation materials, and heat recovery devices to reduce energy dependence. For example, photovoltaic panels can power lighting and exhaust fans, while heat recovery devices preheat fresh air, reducing energy consumption for maintaining internal temperatures.
Integration of Rental Services and Environmental Management
Rental services not only provide facilities but also include environmental management plans. Service providers estimate waste production based on event scale and deploy equipment with corresponding treatment capacity. For large events, multiple microbial degradation toilets can be deployed to ensure on-site treatment capacity matches demand. Technology applications enable on-site treatment, reducing reliance on fixed sewage facilities and avoiding secondary pollution risks during transportation, such as preventing excrement leakage through sealed storage designs.
Material Selection and Cold-Resistant Design
Box materials prioritize recyclable metals or composite materials, with a recycling rate exceeding 80% after service life, reducing construction waste. Internal facilities use long-life components, such as stainless steel flushing devices and corrosion-resistant pipes, to lower replacement frequency. For Heihe's cold climate, piping employs trace heating to prevent liquid freezing; degradation tanks are equipped with insulation layers or heating elements to maintain microbial activity temperatures (typically kept at 10-35°C), ensuring normal operation in winter.
Public Health and Pollution Control
Environmental toilets prevent excrement exposure in open environments through sealed storage and biological degradation technologies, reducing mosquito breeding and bacterial spread. For example, the microbial degradation process can kill over 99% of pathogens, lowering the risk of gastrointestinal infectious diseases. Proper use also maintains personal hygiene habits, especially in crowded areas, where adequate sanitation facilities can prevent mass health incidents, such as diarrhea and skin infections.
