Sewage Tank of Mobile Toilets
The sewage tank of mobile toilets is a crucial component for storing fecal wastewater, and the designs of sewage tanks vary among different types of mobile toilets.

Mobile toilets can be classified into various types based on wastewater treatment methods, with some types involving sewage tank designs. For flush and non-flush suction-type mobile toilets, the non-flush suction-type is usually equipped with a sewage tank to collect fecal wastewater, which is periodically cleaned using suction equipment. For flush-type mobile toilets, if they are not directly discharged, they may also have a sewage tank to temporarily store wastewater for subsequent treatment. Recirculating flush-type mobile toilets generally have a dedicated treatment system to purify and recycle wastewater. However, some designs may also include a sewage tank to store impurities that cannot be recycled or initial wastewater to ensure the normal operation of the recirculation system. Dry-packing-type mobile toilets use biodegradable packing bags or containers to collect feces, and their packing devices can be regarded as a special form of sewage tank. Once full, the packing bags can be directly replaced without the need for complex wastewater treatment processes.
There are various mobile toilet products with fecal tanks (sewage tanks) on the market. For example, mobile toilets with fecal tanks and shower rooms, which are direct-discharge and environmentally friendly for outdoor construction sites, combine the functions of mobile toilets and shower rooms. The design of their sewage tanks needs to consider the usage environment of outdoor construction sites, usually featuring a large capacity and strong sealing to prevent odor emission and wastewater leakage, meeting the needs of a large number of construction site personnel. Mobile toilet restrooms with built-in fecal tanks and water tanks have an integrated design of the sewage tank and water tank, making them compact and suitable for places with limited space, such as small event venues and temporary construction areas. The materials of their sewage tanks are generally selected to be corrosion-resistant and easy to clean, extending their service life and ensuring hygiene conditions.
The prices, specifications, and repurchase rates of mobile toilets with fecal tanks produced by different manufacturers vary. Prices are influenced by multiple factors, such as materials, capacity, and functions. High-quality, large-capacity, and fully functional sewage tank designs result in relatively higher prices for mobile toilets. In terms of specifications, the capacity of sewage tanks varies according to the usage scenario and the number of users. Small-scale events may choose smaller-capacity tanks, while large construction sites or long-term usage venues will opt for larger-capacity ones. The repurchase rate is closely related to product quality and after-sales service. Products with reliable quality and good after-sales service are more popular in the market and have a relatively higher repurchase rate.
