Zhengzhou Mobile Toilet Acceptance Criteria

The acceptance criteria for mobile toilets in Zhengzhou cover three core areas: sink layout, overall quality, and compliance with qualifications. The specific requirements are as follows:

I. Sink Layout Standards

1. Basic Dimensions and Functional Layout: The countertop width must be ≥0.6 meters, with a length of ≥0.8 meters for single-person use. For every additional 10 users, the area should increase by 0.5 meters. The countertop edges should be rounded, and the cabinet depth beneath the countertop should be ≥0.4 meters. The sink should be installed near the entrance (distance ≤3 meters), with faucets featuring sensor or foot-pedal switches. A storage cabinet should be placed below, and the countertop should have a reserved space for soap dispenser installation (spacing ≥0.4 meters).
2. Facility Configuration and Hygiene Prevention: The sink must be equipped with at least two faucets, with water pressure ≥0.15 MPa. The drainage pipe diameter should be ≥110 mm, with an odor-proof trap at the bottom. The sink material should be slip-resistant and waterproof ceramic or stainless steel, and the mirror cabinet should have built-in lighting (brightness ≥300 lux). Near the sink, there should be a trash bin, disinfectant hand soap, and paper towels. The drain should have a filter, ventilation space should be reserved below, and the cleaning and disinfection cycle should not exceed 24 hours.
3. Installation and Acceptance Specifications: The installation must be secure, with tight connections to the main structure and no wobbling. Metal components should be rust-proofed. After installation, a water discharge test should be conducted to ensure smooth drainage without leaks. During acceptance, a test report on safety parameters such as water quality and drainage should be provided.

II. Overall Quality Standards for Mobile Toilets

1. Structure and Materials: The frame should be made of hot-dip galvanized steel pipes or steel structures, featuring high strength, corrosion resistance, and wind pressure resistance. The wall materials should balance aesthetics and durability, with internal filling of flame-retardant insulation materials. The floor must be waterproof and slip-resistant.
2. Sewage System: Depending on the usage environment, choose from water-flush direct discharge, waterless packaging/microbial degradation, or recirculating water flush systems to ensure stability and no odor leakage.
3. Supporting Facilities and Functions: The interior should be equipped with an exhaust fan, lighting, sink, mirror, storage shelf, paper towel holder, and hooks. The ventilation and deodorization system should effectively prevent odor accumulation. Electrical safety should meet moisture-proof, waterproof, and grounding protection requirements.

III. Qualification and Compliance Requirements

1. Qualification Compliance: The manufacturer must provide a full set of documents, including test reports, certificates of conformity, and fire safety materials, to meet municipal and park acceptance requirements.
2. Product Durability: Thickened steel combined with anti-corrosion processes should be used to ensure wind and corrosion resistance, with waterproof and deodorization technologies meeting standards.
3. After-Sales Support Capability: Choose manufacturers that can provide rapid after-sales response and long-term maintenance services to reduce later usage costs.
