Jiuquan Outdoor Mobile Toilet
The outdoor mobile toilets in Jiuquan are temporary sanitation facilities designed according to the local geographical and climatic conditions, featuring unique design characteristics and waste-treatment methods.
In terms of waste collection and treatment, there are various common methods. Portable toilets combined with curing agents or degradable bags can seal and store waste. Small-scale biological reaction devices utilize microorganisms to decompose organic matter. However, in Jiuquan's environment, which is characterized by drought, little rainfall, cold winters, and large temperature differences between day and night, the activity of microorganisms is affected, posing challenges to the stable operation of these devices. Additional insulation or heating designs are often required to maintain microbial activity.
In terms of physical structure, to cope with the windy and sandy environment, the box materials are usually made of glass-fiber-reinforced plastic or high-strength polyethylene that are resistant to ultraviolet aging. Their sealing performance affects internal sanitation and odor control. The structural design focuses on wind resistance stability, achieved by lowering the overall center of gravity, adding weights at the bottom, or using anchorable foundations. The ventilation system is equipped with multiple layers of filters to effectively exchange air and prevent large amounts of sand and dust from entering.
Regarding water resource utilization, given the scarcity of water resources in Jiuquan, traditional water-flushing designs are less applicable, and waterless or micro-flushing technologies have become mainstream. For example, foam sealing technology is used to isolate odors, vacuum suction technology uses a minimal amount of water for cleaning, or replaceable collection bags containing polymer water-absorbing materials are used to convert waste into gel-like solids.
After the service period ends, the common terminal treatment method for waste inside mobile toilets in Jiuquan is to collect it centrally and transport it to urban sewage treatment plants with treatment capabilities. If degradable materials are used for packaging, theoretically, they can be buried and degraded at designated locations, but this is strictly limited by local soil and climatic conditions. Waste liquids that have undergone preliminary biological treatment need to undergo professional testing to ensure they meet safety standards before being reused for specific purposes or discharged. The entire process must avoid causing secondary impacts on the fragile ecological environment.
In addition, there are numerous merchants in Jiuquan offering mobile toilet rental services, which can meet the needs for outdoor mobile toilets in various scenarios such as military training, temporary events, and scenic area drills.
