Binhai Environmental Protection Mobile Toilet

Binhai environmental protection mobile toilets are widely used in the Binhai New Area, with main technical types including biodegradable, vacuum collection, and recirculating water flushing types, and they have many features in terms of materials, power supply, and functional realization.

Diverse technical types The biodegradable type relies on microorganisms to decompose excrement. It is internally filled with a specific strain culture medium, and aerobic or anaerobic microbial communities decompose organic matter into carbon dioxide, water, and a small amount of humus. It does not require external water for flushing, and the volume of the residue is only five to ten percent of the original input. The vacuum collection type relies on negative pressure suction technology. After a user uses the toilet, the system starts the vacuum pump and sucks the waste into a sealed collection device with a very small amount of water or foam. Each flush consumes 0.5 to 1.2 liters of water, which is much lower than that of ordinary water-saving toilets. The pipe diameter can be reduced, making temporary layout more flexible. The recirculating water flushing type is equipped with a small water treatment unit. After flushing, the sewage undergoes multi-stage filtration, microbial treatment, and disinfection to meet the hygiene standards for reuse in flushing, forming a closed water circulation loop. A standard single unit has an internal daily water circulation volume of about 200 to 300 liters, with only a small amount of loss needing to be replenished.

Materials and structural design adapted to the marine climate In the Binhai New Area, the boxes of rented environmental protection toilets are generally made of fiberglass-reinforced plastic or corrosion-resistant aluminum alloy. The surface coating has anti-salt-fog properties, and most of the connecting parts are made of stainless steel to cope with the corrosion of the marine climate. The internal ventilation system has been optimized to effectively deal with the humid environment and prevent premature aging of the internal components of the equipment.

Flexible functional realization There are various temporary power supply solutions. In addition to conventional mains power connections, some units are equipped with solar photovoltaic panels and battery packs, which can maintain the operation of basic lighting and ventilation systems for several days in areas without a power grid. The capacity design of the collection devices is based on the expected number of users, and the cleaning cycle can range from several days to several weeks, reducing the frequency of operation and maintenance. In addition, the mobile sanitation facilities available for rent in the Binhai New Area can also be divided into biodegradable and chemical treatment types according to technical types. The biodegradable type relies on microbial decomposition and does not need to be connected to the sewer, making it suitable for temporary outdoor activities. The chemical treatment type decomposes waste by adding chemical agents and is commonly used in situations where quick installation is required. Both types have independent operation capabilities and are not restricted by fixed pipelines.
