Standardization of Mobile Toilets
The standardization of mobile toilets is reflected in multiple aspects such as dimensions, structure and materials, sewage treatment methods, design principles, and market-supplied products.
Dimension Standards: Mobile public toilets have clear dimensional specifications. The standard dimensions are typically 2 meters by 1.2 meters, but barrier-free toilet compartments require larger dimensions, with a net size of at least 1.8 meters by 1.5 meters. Additionally, a 1.5-meter square turning area for wheelchairs must be provided, and the door width must be at least 80 centimeters, preferably an outward-opening or electric door. The length of a single toilet compartment ranges from 1 meter to 1.5 meters, and the width ranges from 85 centimeters to 1.2 meters. Common overall public toilet dimensions are 2 meters in length, 1.2 meters in width, and 2 meters in height, occupying an area of approximately 5 to 10 square meters. These dimensional standards ensure the applicability and convenience of mobile toilets, meeting the needs of different user groups.
Structure and Material Standards: Mobile toilets are generally composed of fecal sewage storage tanks (or fecal sewage treatment devices), floor slabs, sanitary ware, walls, washing equipment, water tanks, roofs, and mobile devices. Their materials have gradually evolved from initial wood to fiberglass-reinforced plastic and polyethylene to adapt to different environmental requirements. For example, in cold northern regions, the interior of the walls is insulated, and the entrance doors are made of thickened titanium-magnesium alloy. The selection of these materials and the design of the structure adhere to standardized principles, enhancing the durability and adaptability of mobile toilets.
Sewage Treatment Method Standards: Mobile toilets can be classified into various types based on sewage treatment methods, including water-flush and waterless-flush suction types, circulating water-flush types, and dry-packing types. Each of these different sewage treatment methods has corresponding standard requirements to ensure the environmental friendliness and hygiene of mobile toilets.
Design Principle Standards: The design of mobile toilets should adhere to the principles of mobility and convenience, economic durability; environmental protection and ecological benefits; and enhancing efficiency and promoting humanity. The overall structure should consider lightness, using lightweight and durable materials as much as possible; the structure should be sturdy; the design should also consider controlling the height and width of the toilet; and the mobile device should be fully considered for completeness and rationality.
Market-Supplied Standardized Products: There are various standardized mobile toilet products available on the market, such as the standardized mobile toilets provided by Zhongcheng Lvjian Prefabricated Building Technology Co., Ltd. in Weifang, Shandong, which are corrosion-resistant and priced at 1200.00 yuan per square meter; and the towable outdoor mobile toilets provided by Shandong Kangpai Kitchenware Co., Ltd. in Zibo, Shandong, which are sturdy, durable, and easy to disassemble, priced at 20,000 yuan per set.
