Beijing Changping Simple Mobile Toilets
Beijing Changping offers a variety of simple mobile toilets, including single-unit, trailer-mounted, frame-assembled, and water-saving and environmentally friendly types, to meet the needs of different scenarios. The following provides an introduction from four aspects: types, specifications, technology, and leasing services:
Types and Applicable Scenarios
Single-unit mobile toilets feature an independent box structure, can be transported as a whole, and are quickly installed, making them suitable for temporary events or construction sites. Trailer-mounted toilets come with a wheelbase, offering greater capacity and treatment capabilities, and are ideal for long-term parking in fixed locations such as park auxiliary areas and seasonal tourist attractions. Frame-assembled toilets adopt a modular design, allowing for expanded internal space after on-site assembly, and are suitable for large-scale event support or long-term construction project campsites with high foot traffic. Water-saving and environmentally friendly types include recirculating flush toilets (equipped with a water treatment system to recycle flush water), microbial degradation toilets (using bacterial agents to decompose waste), and foam-sealing toilets (with high water-saving rates and reduced odors), suitable for scenarios with high environmental protection requirements.
Common Specifications and Structural Dimensions
Small single-unit toilets typically measure 1.2×1.2×2.3 meters, containing one squat or sit toilet, with a compact structure. Standard single-unit toilets measure 1.5×1.5×2.3 meters or 1.8×1.8×2.4 meters, accommodating standard toilet stalls and sinks. Multi-stall combined units consist of multiple standard units connected side by side, with a 2-unit combined toilet measuring approximately 3 to 3.6 meters in length. Toilets with barrier-free facilities have a door width of no less than 0.9 meters, an internal turning diameter of no less than 1.5 meters, and external dimensions such as 2.0×2.0×2.4 meters or larger, with boxes often made of galvanized square steel frames and materials like color-coated steel plates and aluminum-plastic panels.
Technical Standards and Treatment Mechanisms
The core of mobile toilets is an integrated treatment system that combines collection, storage, and preliminary treatment functions. The treatment mechanism operates in two stages: physical separation achieves solid-liquid separation through gravity or mechanical means; biochemical decomposition uses microbial agents or chemical agents to treat the separated liquid for harmless disposal or odor degradation. In leasing mode, equipment configuration follows a modular principle, combining functional modules based on estimated foot traffic, duration, and environmental conditions.
Leasing Services and Agreement Terms
Agencies in Changping District, such as Beijing Kangjie Environmental Protection Equipment Leasing Center, offer leasing services covering needs assessment,方案设计 (scheme design), equipment delivery, installation and commissioning, and regular inspection and maintenance. Key terms in the leasing agreement clarify rights, responsibilities, and service standards: the supplier is responsible for equipment transportation, installation, maintenance, cleaning, waste removal, and withdrawal; the user must provide the site, ensure the external safety of the equipment, and use it as agreed.
