Jiangsu Mobile Toilet Environmental Protection Standards
The environmental protection standards for mobile toilets in Jiangsu must comply with national standards and industry norms, covering aspects such as hygiene and safety, odor control, material environmental friendliness, sewage treatment, resource conservation, and adaptability to special scenarios. The specific requirements are as follows:
1. Hygiene, Safety, and Health Protection
They must meet the requirements of 'Antibacterial, Bactericidal, and Purification Functions for Household and Similar Electrical Appliances - Part 7: Special Requirements for Electric Toilet Seats' (GB/T 23132-2025), with a bactericidal rate of ≥90% and a virus removal rate of ≥99%. Materials in contact with the human body (such as toilet seats and handrails) must possess antibacterial and anti-mold properties to prevent cross-infection. Additionally, according to the 'Hygiene Standards for Urban Public Toilets' (GB/T 17217), the total number of airborne bacteria and the detection of coliform bacteria on high-frequency contact surfaces (such as toilets and door handles) must meet the standards to ensure a hygienic and safe usage environment.
2. Odor Control and Air Quality
Based on the 'Emission Standards for Odor Pollutants' (GB 14554), the concentration of odor gases such as ammonia and hydrogen sulfide must be controlled through ventilation systems or deodorization technologies (such as activated carbon adsorption and photocatalytic oxidation). The ventilation design must comply with the 'Design Standards for Urban Public Toilets' (CJJ 14-2016), adopting a combination of natural and mechanical ventilation to ensure that the toilet is ventilated at least six times per hour, preventing odor accumulation.
3. Environmentally Friendly and Durable Materials
It is recommended to use recyclable or biodegradable materials (such as HDPE and stainless steel) and limit the use of harmful substances like lead and cadmium to reduce environmental pollution in accordance with the 'Green Product Evaluation - Sanitary Ceramics' (GB/T 35600-2017). The main structure must use national standard steel (such as square tubes ≥50×100mm) with surface anti-corrosion treatment and a service life of ≥15 years to prevent sewage leakage and comply with the requirements of the 'General Technical Conditions for Mobile Toilets' (GB/T 38837-2020).
4. Sewage Treatment and Resource Conservation
Sewage discharge must meet the 'Integrated Wastewater Discharge Standard' (GB 8978-1996), setting limits on indicators such as chemical oxygen demand (COD) and biochemical oxygen demand (BOD5), and must be discharged after meeting the standards or transported in compliance with regulations. In terms of water conservation, according to the 'Water-Saving Sanitary Ware' (GB/T 31436-2015), it is recommended to use foam-sealing or vacuum-suction toilets with a single flush volume of ≤0.5 liters. The use of reclaimed water recycling technology is encouraged to achieve water resource circulation.
5. Adaptability to Special Scenarios
For extreme environments (such as -40℃ to 50℃), insulation materials must be used and heating devices must be equipped to prevent pipeline freezing; in sandy or high-humidity areas, the structural sealing must be enhanced. Barrier-free design must comply with the 'Codes for Design on Accessibility' (GB 50763-2012), with toilet cubicle widths of ≥900mm and equipped with handrails and anti-slip facilities.
Additional Requirements for Jiangsu Region: Temporary facilities on construction sites must be cleaned daily and disinfected regularly. Some cities are piloting smart mobile toilets that optimize management efficiency through IoT technology. When purchasing, products that comply with the GB/T 26757 standard must be selected, and environmental protection test reports must be provided.
