Recommendation of Mobile Toilets for Rongchang Exhibition

For mobile toilets at the Rongchang Exhibition, it is recommended to prioritize microbial degradation-type products and conduct a comprehensive evaluation from three dimensions: technical parameters, supplier qualifications, and product selection. Here are the specific recommendations:

I. Technical Type Selection: Microbial Degradation-Type Mobile Toilets This type of toilet achieves solid waste reduction through biodegradation technology, with core parameters that must meet the following requirements:

• Degradation Efficiency: Solid waste reduction should reach over 95%, with the final products being carbon dioxide and a small amount of organic fertilizer, meeting environmental protection requirements.
• Odor Control: Negative pressure ventilation systems and biological deodorizing bacteria should be used to ensure air quality meets national secondary standards, preventing odor diffusion during the exhibition.
• Load-Bearing Capacity: Each toilet cubicle should handle 80-120 person-times per day on average. For large-scale or long-duration exhibitions, enhanced circulation systems should be configured to improve processing capacity.
• Energy Consumption Control: Daily power consumption should be 3-5 kWh, suitable for long-term continuous use and reducing operational costs.

II. Supplier Qualification Requirements According to the bidding standards for the Rongchang District reserve project, suppliers must meet the following conditions:

• Construction Qualifications: They should possess a Grade III or higher qualification in general contracting for construction engineering to ensure the standardization of installation and maintenance.
• Customization Capabilities: Priority should be given to enterprises that can provide original custom processing (such as Shanghai Dongba Construction), supporting the customization of metal products to meet special exhibition needs.
• Technological Iteration Capabilities: Suppliers should have the ability to upgrade environmental protection technologies (such as the advantages of Yijie Environmental Protection in extreme climate stability) to cope with complex environments.

III. Product Selection Points Considering the characteristics of exhibition activities, the following parameters should be verified:

• Materials: The outer shell should be made of stainless steel 304 or galvanized steel, which is corrosion-resistant and easy to clean, extending the service life.
• Tank Capacities: The sewage tank should have a capacity of 100-200L, and the clean water tank 50-100L. Larger capacities reduce the frequency of cleaning but should be balanced against costs based on the exhibition scale.
• Basic Configurations: Essential facilities such as washbasins, lighting, and exhaust fans must be included to enhance the user experience.
• Structural Design: Modular design facilitates transportation and installation, with sealed connections to prevent leakage.

IV. Typical Case References

• Shanxi Jinci Scenic Area increased its daily reception capacity from 3,000 to 5,000 person-times by flexibly deploying bus-type mobile toilets, demonstrating the applicability of modular design in high-traffic scenarios.
• Lanzhou Yellow River Scenic Line adopted circulating water flushing technology, suitable for exhibition scenarios with water scarcity or high environmental protection requirements.

It is recommended to prioritize contacting original manufacturers with microbial degradation technology patents (such as Yijie Environmental Protection and Shanghai Dongba Construction) to customize solutions based on the exhibition scale, budget, and environmental protection requirements.
