Fecal Treatment of Mobile Toilets in Xi'an
The fecal treatment methods for mobile toilets in Xi'an mainly include regular suction and centralized treatment, collection and transportation, biodegradation, chemical treatment, and other types of treatment.
Regular suction and centralized treatment: Mobile toilets are equipped with sewage tanks at the bottom to collect feces and sewage. When the capacity of the sewage tank reaches a certain limit, professional cleaning personnel will use suction equipment to extract the feces and sewage and transport them to a specialized fecal treatment center. These treatment centers employ methods such as biodegradation, chemical treatment, or physical treatment to render the feces and sewage harmless, ensuring no pollution to the environment.
Collection and transportation: For standalone mobile toilets, they are usually equipped with detachable fecal storage buckets or plastic bags. These fecal storage facilities require regular manual cleaning, and the collected feces and sewage are transported to designated treatment points. For rows of mobile toilets used in large-scale events, they are connected via pipes to underground fecal storage tanks, which are then suctioned out by professional fecal suction trucks and sent to sewage treatment plants for processing.
Biodegradation: Biodegradable mobile toilets utilize added microbial agents to decompose feces, converting them into harmless substances such as water and carbon dioxide. This treatment method is suitable for long-term fixed locations but requires regular replenishment of microbial agents and control of usage intensity to ensure the activity of the microorganisms.
Chemical treatment: Chemical toilets use blue or green chemical agents to decompose feces, inhibit bacterial growth, and reduce odors. However, the treated wastewater needs to be disposed of as hazardous waste and cannot be discharged arbitrarily to prevent environmental pollution.
Other types of treatment: Dry-packing mobile toilets use biodegradable plastic bags to collect excreta, which are then collected and transported to treatment plants for disposal after use. Foam-sealing mobile toilets use foam generated by a foaming liquid mixture instead of toilet flushing water to conserve water resources. Recirculating flush mobile toilets accelerate the fermentation and decomposition of fecal sewage through biofilm technology, reducing the frequency of suction and improving treatment efficiency.
