National Standards for Mobile Toilets
The national standards for mobile toilets mainly involve two categories: waterless sanitary toilets and mobile environmentally friendly public toilets, with specific standards as follows:
Waterless Sanitary Toilets: These toilets are regulated by the GB/T18092-2000 'Waterless Sanitary Toilets' standard, which has been officially implemented since October 1, 2000. This standard is primarily designed for locations without access to water supply and drainage systems, such as remote areas, temporary event venues, or regions with scarce water resources. Its core feature is the treatment of excreta through physical or chemical means, without relying on traditional water-flushing systems, thereby reducing water consumption and sewage discharge. For example, some waterless toilets employ biodegradation technology, utilizing microorganisms to decompose excreta into harmless substances; or achieve solid-liquid separation, deodorization, and sterilization by adding special agents. The promotion of these toilets effectively addresses the challenge of sanitation in areas without water supply and drainage, while also meeting environmental protection requirements.
Mobile Environmentally Friendly Public Toilets: Their standards are based on the GBLT18091-92 standard, achieving efficient water conservation and environmental protection functions through technological optimization. This standard requires public toilets to have the capability to automatically collect hand-washing water and add special agents, enabling each flush to use only 0.46 liters of water, significantly lower than the water consumption of traditional public toilets. Internally, they are equipped with an independent toilet pit partitioned treatment system: the urine channel utilizes gravity flow design to reduce mechanical energy consumption; the feces channel is cleaned by a piston-type scraper mechanical device to ensure rapid transfer of excreta to the treatment unit. Additionally, the toilets are equipped with non-slip floors, automatic flushing toilet bowls, and ventilation and lighting systems to enhance safety and comfort during use. For example, the ventilation system maintains air circulation through forced exhaust or natural ventilation, while the lighting system uses energy-efficient lamps to reduce energy consumption. These toilets are suitable for temporary or fixed locations such as city streets and tourist attractions, balancing environmental protection with practicality.
Both sets of standards emphasize environmental protection, water conservation, and applicability, but differ in their applicable scenarios and technological approaches. Waterless toilets focus more on independent operation under waterless conditions, while mobile environmentally friendly public toilets achieve water conservation and functional completeness through technological integration, jointly promoting the standardization development of the mobile toilet industry.
