Tiantai Mobile Toilet Fecal Extraction
The fecal extraction operation for mobile toilets in Tiantai involves using specialized equipment and vacuum negative pressure technology to transfer waste from the storage tank of the mobile toilet to a treatment site. Here is a detailed introduction:
Equipment Composition: The fecal extraction truck is the core equipment, equipped with a vacuum pump, storage tank, fecal suction pipe, and control system. The fecal suction pipe is typically made of wear-resistant and corrosion-resistant flexible materials to ensure it is not damaged by friction or corrosion during the suction process. The storage tank must have sufficient capacity and corrosion resistance to accommodate a large amount of waste and prevent leakage. The vacuum pump provides the necessary suction force and is the key component for creating a negative pressure environment. The filtration device is used to separate gas from solids, reducing pump wear and controlling odor diffusion to ensure a relatively clean working environment.
Operation Process: Before operation, staff must wear necessary protective gear and conduct routine inspections of the equipment to confirm that the vacuum pump, pipes, and valves are in normal condition. Park the fecal extraction truck in a safe position next to the mobile toilet, engage the handbrake, and place warning signs. Connect the fecal suction pipe to the sewage outlet of the mobile toilet, ensuring a tight and error-free connection. Start the vacuum pump to create a negative pressure environment inside the storage tank, allowing external atmospheric pressure to force the contents of the storage tank into the tank through the fecal suction pipe. Operators must closely monitor the equipment's operating sounds and pressure gauge readings to determine if the suction is smooth. If a blockage occurs, stop the machine immediately and use specialized tools to clear it; avoid forcing the operation. When the contents of the storage tank are exhausted or the fecal extraction truck's storage tank is nearly full, turn off the vacuum pump, disconnect the fecal suction pipe, and seal the sewage outlet of the mobile toilet. Finally, clean the work site to ensure no residual waste remains.
Subsequent Treatment: After the fecal extraction operation is completed, the fully loaded fecal extraction truck transports the waste to a designated treatment plant. Upon receiving the waste, the treatment plant performs solid-liquid separation to separate solid residues from liquids. The liquid portion enters the sewage treatment system, where it undergoes biochemical treatment to meet standards before being discharged or reused. The solid portion may undergo composting treatment to be converted into organic fertilizer or undergo harmless landfilling.
