Mobile Toilet Feces Removal
There are mainly three methods for mobile toilet feces removal: centralized removal and treatment, traditional and waterless flushing removal, and removal with advanced treatment technologies.
Centralized removal and treatment: Before using a mobile toilet, deodorants and flocculants should be added to the feces tank. Deodorants can effectively reduce the odor produced by feces, improving the usage environment; flocculants can reduce the fluidity of fecal liquid, preventing leakage during the removal process. After use, the sealed valve should be closed to ensure that feces do not overflow. Then, qualified sanitation or environmental protection companies use vacuum suction trucks to extract the feces from the feces tank into a dedicated transfer tank and transport it to urban sewage treatment plants or feces disposal stations. At the sewage treatment plant, the feces undergo a series of treatment processes, such as grid filtration to remove larger solid impurities; anaerobic fermentation and aerobic treatment to decompose the organic matter in the feces, converting it into harmless reclaimed water and sludge. After dewatering treatment, the sludge can be used for composting or incineration, achieving resource reuse.
Traditional water-flushing and waterless-flushing mobile toilet removal: Traditional water-flushing mobile toilets rely on water-flushing devices to flush feces into the sewage tank at the bottom; while waterless-flushing mobile toilets directly receive the excreta of users through the sewage tank set at the bottom. Since the volume of the sewage tank is limited, when the number of users reaches a certain level, the sewage tank will gradually fill up. If it is not promptly emptied using a feces suction truck at this time, feces are prone to overflow, which will not only affect the normal use of the mobile toilet but also cause pollution to the surrounding environment.
Removal of mobile toilets equipped with advanced treatment technologies: In recent years, with the advancement of technology, more and more mobile toilets have begun to be equipped with advanced feces treatment technologies, such as intermittent aerobic and anaerobic treatment, biofilm technology, etc. These technologies can accelerate the fermentation and decomposition process of fecal sewage. Through filtration devices, the treated fecal sewage is purified and can be recycled for flushing the toilet. This treatment method significantly reduces the frequency of fecal sewage suction, cuts removal costs and environmental impact, and also improves the efficiency of water resource utilization.
