Customization of Portable Toilets for Construction Sites in Hubei

The customization of portable toilets for construction sites in Hubei requires selecting the appropriate type and adapting technical parameters according to specific needs. The following are common types and key customization points:

Waterless Flush Portable Toilets
This type focuses on environmental protection, using color-coated steel plates or metal carved panels as materials. Specifications include sizes such as 1.3×1.3×2.3 meters and 1.5×1.8×2.3 meters, with an applicable temperature range of -10℃ to 50℃ and a voltage of 220V. Its advantages lie in no need for a water source, low cost, and the ability for bulk customization, making it suitable for construction sites with short construction periods and strong temporary needs. During customization, it is necessary to confirm the corrosion resistance of the material (such as rust prevention treatment for metal carved panels) and whether the specifications match the personnel flow at the construction site. For example, larger specifications can be selected for high-density work areas to reduce queuing time.

Microbial Portable Toilets
These toilets decompose organic waste through microorganisms and require customizing the bacterial strain ratio and carrier design according to the construction site environment. Key parameters include:

1. Bacterial Strain Selection: In high-temperature and high-humidity environments in summer, heat-resistant bacterial communities are needed, while in low-temperature construction sites in winter, low-temperature-adaptive bacterial strains are required to ensure decomposition efficiency;
2. Carrier Materials: Porous ceramics or activated carbon need to pass laboratory tests to verify their resistance to erosion by local water quality (such as the hard water quality in some areas of Hubei);
3. Gas-Liquid Balance: A segmented aerobic system is adopted to maintain bacterial community activity through timed oxygen supply, and trace amounts of nutrient salts are added to adjust the carbon-nitrogen ratio and suppress odors.
   These toilets are suitable for long-term use at construction sites but require regular replenishment of bacterial agents and maintenance of aeration equipment.

Foam-Flush Portable Toilets
These toilets use foam instead of clean water for flushing and require adjusting technical parameters according to the climate in Hubei:

1. Foam Liquid Formula: In summer, the concentration of surfactants needs to be increased to enhance foam stability, while in winter, antifreeze components (such as ethylene glycol) are added to prevent pipeline freezing;
2. System Composition: The storage module uses a corrosion-resistant polyethylene tank, the pneumatic module includes an air compressor and foam head, and the control module automatically adjusts the foam volume according to the frequency of use;
3. Environmental Adaptation: During the rainy season, the foam formula needs to be optimized to reduce the defoaming speed in humid environments, and modular design is required for construction sites in mountainous areas for easy transportation.
   These toilets have significant water-saving effects but require regular cleaning of the foam head to prevent blockages.

Men's Exclusive Portable Toilets
Designed specifically for the needs of men at construction sites, the custom design includes a ridge-shaped roof, galvanized steel frame structure, and multi-colored exterior. The interior is equipped with a sink cabinet to enhance convenience. For these toilets, it is crucial to focus on structural stability (such as a steel frame thickness of ≥3mm) and rust prevention treatment (such as hot-dip galvanizing process) to adapt to the complex environment of construction sites.
