Qiaokou Street Mobile Toilet
The mobile toilets on Qiaokou Street involve multiple technical principles and practical requirements, and the following points need to be comprehensively considered when renting:
Sewage Discharge System: It is divided into vacuum suction type and gravity self-storage type. The vacuum type relies on negative pressure difference to suck waste into the collection tank, and a location with a flat ground and a turning radius greater than 6 meters from the suction vehicle is required; the gravity type relies on the slope to naturally flow into the tank. If the ground slope exceeds 3 degrees, it will affect the effective volume. Before renting, a level gauge should be used to detect the ground flatness and calculate the soil bearing capacity.
Modular Structure: Attention should be paid to the compatibility of water and electricity interfaces. The circuit module usually adopts a 24V DC safety voltage, but the charging interfaces of different models are not universal. If the power supply point is not equipped with an adapter, a voltage transformation module needs to be installed (with an energy loss of about 5%-8%); inconsistent thread standards for water supply and drainage interfaces may lead to leakage of sealing gaskets. When renting, the interface specification list should be verified.
Microbial Degradation: The activity of biodegradable bacterial agents is affected by temperature and stirring frequency. When the average annual temperature in Qiaokou is 15-20℃, the half-life of the bacterial community in decomposing solid waste is 6-8 hours. If the rental period exceeds 48 hours and no bacterial agent is supplemented, the increase in organic acid concentration in the tank will cause the pH value to drop below 5, and the hydrogen sulfide production will increase by more than three times. It is necessary to rent a bacterial agent supply package simultaneously or arrange for intermediate pumping and drainage.
Wind Load Stability: Lightweight structures may slide sideways when the wind speed exceeds 10 meters per second. In areas near rivers, the local wind speed increases by 20%-30% due to the 'venturi effect'. When renting, the lessor should be required to provide a wind resistance coefficient calculation sheet. Priority should be given to models equipped with water-filled ballast tanks at the bottom (with a water filling volume of no less than 200 liters per tank) or fixed with ground anchor ropes (with the ground anchor point at least 1.5 meters from the wall foundation).
Odor Diffusion Control: The deodorization system works through the collaboration of a negative pressure fan and an activated carbon filter. The fan air volume needs to be more than 12 times the internal volume of the public toilet to maintain a micro-negative pressure state. If the rental location is downwind and there are ventilation shafts around, the increase in air humidity will reduce the adsorption efficiency of the filter.
Other Technical Points: The water flushing system adopts vacuum negative pressure suction technology, requiring only 0.5-1 liter of water per flush, which can extend the rental period; the sewage storage tank inhibits the activity of sulfur-producing bacteria through the pre-dosing technology of biological enzymes; the double-layer composite material shell and anti-settlement diversion plate design can adapt to areas with a ground bearing capacity of less than 0.15 megapascals.
