Shaoxing Environmental Protection Mobile Toilet Design
The design of Shaoxing's environmental protection mobile toilets is reflected in multiple aspects such as ventilation, double-unit design, customization, and environmental protection.
In terms of ventilation design, a combination of natural and mechanical ventilation is adopted. Natural ventilation relies on the air convection formed by the top openable skylights and side windows. On sunny days, the skylights are opened to introduce fresh air, and the side windows are equipped with screens to prevent mosquitoes. The materials used are lightweight and smooth-surfaced color steel plates, PVC plates, etc. Some walls are treated for ventilation, such as using honeycomb aluminum panels. An odor removal system is installed to discharge odors through ventilation ducts, combined with fragrances or deodorants. A ventilation fan can also be installed inside for regular air exchange. Daily maintenance is emphasized, including regular cleaning of dust on the skylights and side windows, checking the operation of the ventilation fans, and regular comprehensive cleaning by the sanitation department to prevent ventilation openings from being blocked.
The double-unit design adopts a side-by-side form, which can meet the needs of multiple people using it simultaneously, such as a combination of separate men's and women's toilets or a shared space for two toilets. It has significant advantages in crowded scenarios such as during the peak tourist season in scenic spots. Taking a scenic spot that receives tens of thousands of visitors per day during the peak season as an example, its usage efficiency is more than 50% higher than that of a single toilet, greatly reducing queuing time.
In terms of customization design, local merchants in Shaoxing support full customization. They can carry out personalized design from dimensions, materials to functional modules according to different usage scenarios and needs. Double-unit toilets for construction sites can have thicker panels and increased compressive strength; those for scenic spots can be paired with wood-grain exteriors, non-slip floors, and can also integrate sinks and lighting systems.
In terms of environmental protection design, a water-saving flushing system is adopted, with a single flush volume of only 3 - 5 liters, avoiding water waste. The main body materials are recyclable fiberglass or stainless steel, which are corrosion-resistant and easy to clean. The fecal waste treatment supports ecological degradation technology or centralized collection, meeting environmental protection requirements. The energy supply mostly uses solar panels or small generators. The water circulation system can reuse cleaning water multiple times. Waste disposal follows the principle of classification. The solid part can be used as a raw material for fertilizer after treatment, and the liquid part is discharged after meeting the standards.
