Yichang Construction Site Portable Toilet Rental
Portable toilets at construction sites in Yichang mainly offer rental services, with unique operating principles and functional designs that meet sanitation needs in the absence of fixed sewer networks on construction sites.
Sewage Discharge Principle
Portable toilets operate independently of fixed sewer networks, with the core of sewage discharge being the creation of artificial pressure differences. When a user presses the flush button, an electric pump or manual piston creates a local low-pressure zone within the sealed water tank, and external atmospheric pressure forces water from the storage tank into the toilet bowl, achieving the flushing function. Additionally, all pipe connections are equipped with one-way check valves that allow fluid to move in only one direction, preventing sewage backflow and ensuring the normal operation of the sewage discharge system.
Tank Structure
The interior of the tank is divided into two layers, with the upper layer being the liquid zone and the lower layer being the solid sedimentation zone. This layered design facilitates the classification and treatment of excreta, making subsequent cleaning and discharge easier. A vent valve with an activated carbon filter layer is installed at the top, allowing gases to be slowly released through capillary action while the activated carbon filter layer adsorbs odor molecules, effectively reducing odors in the toilet and improving the usage environment.
Volume Reduction Treatment Technology
Some modern portable toilets used in rental services also employ phase change principles from thermodynamics for volume reduction treatment. The tank surface is coated with a light-colored coating that reflects most solar radiation, reducing heat absorption. The phase change material in the interlayer maintains a constant temperature within the tank in a range where microbial activity is low, inhibiting microbial decomposition of excreta and thus reducing odor production. More advanced models are equipped with built-in electric heating rods that cause moisture to escape as steam, reducing the volume of solid residues to one-third of their original volume, significantly lowering the frequency of cleaning and transportation costs.
Service Forms
At construction sites in Yichang, portable toilets are mainly provided in the form of rentals and leases, allowing construction sites to flexibly adjust the quantity and duration of use according to the construction period and the number of personnel, meeting sanitation needs at different stages.
