Yongan Park Mobile Toilet

Yongan Park has public toilets, but it is not explicitly mentioned whether mobile toilets are used and their specific types. Here is a detailed introduction:

Location of Public Toilets in Yongan Park

Yongan Park is equipped with public toilets, specifically located near the intersection of Xihuan Road and Yongan Park Road in Changping District, Beijing. Additionally, new public toilets have been added in the extension projects of the corner tower of Yongan Park and Sanjiaodi Park. These new public toilets meet the exemption criteria for "adding small service facilities to existing urban green islands" and are about to be put into use. This move further enriches the park's service functions and provides more convenience for visitors.

Common Types and Principles of Mobile Toilets in Parks

Although it is not clear whether Yongan Park uses mobile toilets, there are several common types of mobile toilet designs in the market for parks:

• Packing-type mobile toilets: These toilets collect excrement by packing it in biodegradable plastic bags. After a user uses the toilet, feces and urine are automatically collected into the plastic bag. When the bag is full, it can be disposed of collectively. Their advantages include no need for water, making them suitable for areas with scarce water resources, and easy mobility, allowing them to be relocated at any time.
• Water-flush mobile toilets: Similar to traditional water-flush toilets, they store water in a tank and use the force of water to flush excrement into a septic tank or sewage pipe. Water-flush mobile toilets are clean and hygienic, offering a good user experience, but they require connection to a water source and sewage discharge pipes, posing certain requirements for infrastructure.
• Vacuum suction mobile toilets: These toilets use a vacuum pump to generate negative pressure, quickly sucking away excrement and transporting it to a storage container. This type of toilet uses a small amount of water, has a strong flushing force, effectively reduces odor emission, and occupies a relatively small area, making it suitable for use in parks with limited space.
• Biodegradable mobile toilets: These toilets use microorganisms to decompose excrement, converting it into harmless substances such as carbon dioxide, water, and organic fertilizers. Biodegradable mobile toilets have good environmental performance and do not require frequent cleaning, but they need regular addition of microbial strains to ensure the decomposition effect.
