Quality of Mobile Toilets in Shanxian (Now Shanzhou District)

The overall quality of mobile toilets in Shanxian (now Shanzhou District) is good, meeting high standards in terms of material structure, sewage disposal systems, supporting facilities, and functions.

Material and Structure: The main frames of high-quality mobile toilets are mostly made of hot-dip galvanized steel pipes or steel structures, which have high strength, corrosion resistance, and wind pressure resistance, ensuring the stability and durability of the toilets. There are various choices for wall materials. The exterior walls commonly use metal carved panels and color-steel composite panels, while the interior walls often use stone-plastic panels and aluminum-plastic panels, which are easy to clean and moisture-proof. The interior of the walls is filled with flame-retardant insulation materials (such as rock wool) to meet fire protection requirements. The floors are waterproof and anti-slip, often using anti-slip patterned aluminum panels or reinforced composite floors to ensure safety during use. Shanzhou District has implemented a replacement program for four mobile public toilets, including the one on Century Avenue No. 4 in the urban area. The newly replaced public toilets are likely to meet these quality requirements in terms of material and structure.

Sewage Disposal Systems: There are various types of sewage disposal depending on different usage environments and the availability of external sewage pipes. The water-flush direct-discharge type is connected to municipal sewage pipes, with a stable and water-saving flushing system. The waterless packing/microbial degradation type is suitable for places without sewage pipe networks, featuring good sealing, no odor leakage, and high degradation efficiency. The recycled water flushing type purifies the flushing water through biological treatment technology and then recycles it, with good water purification effects and stable recycling systems. Shanzhou District has arranged for the replacement of water tanks and partitions in public toilets with water tank and partition issues, and has added new squat-stall partitions, which help improve sewage-related functions.

Supporting Facilities and Functions: The basic configurations are complete, including exhaust fans, lighting fixtures, sinks, mirrors, shelves, paper towel holders, and hooks. The ventilation and exhaust systems are effective, equipped with high-power exhaust fans or active fresh air systems to prevent odor accumulation. All electrical circuits have moisture-proof, waterproof, and grounding protection. The newly built public toilets in Shanzhou District follow humanized design standards. They are equipped with mobile phone stands, coat hooks, and item placement shelves in the squat-stall partitions, and are furnished with hand dryers and air fresheners. There are also service counters providing hot water and consultation services. In addition, they meet the requirements for barrier-free public toilets, with ramp railings and high-low sinks, and are open 24 hours a day, greatly enhancing the user experience.
