Xiushan Mobile Toilet Sewage Disposal

The sewage disposal methods for mobile toilets in Xiushan are diverse, mainly including water-flush type, waterless-flush type, chemical treatment type, vacuum drainage type, direct-discharge type, mobile sewage tank type, packing type, and microbial degradation type, etc..

Water-flush type (with sewage tank): This type of mobile toilet is equipped with a top water tank for flushing and a bottom sewage collection tank. After use, a small amount of water is used for flushing, and the waste enters the sewage tank. When the sewage tank reaches its capacity limit, it needs to be cleaned by a professional vehicle to ensure the normal use of the toilet.

Waterless-flush type (dry packing): It does not use water for flushing. Excreta are collected in biodegradable plastic bags. After each use, the system automatically replaces the bag with a new one, sealing and isolating the waste. When full, they are uniformly transported to a treatment plant for harmless treatment, which is both environmentally friendly and hygienic.

Chemical treatment type: Special chemical agents are added to the toilet bowl to decompose, disinfect, and deodorize the excreta. The treated substances have reduced toxicity and can be discharged into the ordinary sewage system or designated collection points, effectively reducing environmental pollution.

Vacuum drainage type: It uses negative pressure suction to quickly draw away the waste, requiring only a very small amount of water (about 0.5 - 1 liter per use) to complete flushing and transportation. The waste is sent to and stored in an on-board or stationary sewage tank and is then transported collectively when full, improving the sewage disposal efficiency.

Direct-discharge type: Some mobile toilets are equipped with special interfaces. In campsites or fixed locations with the necessary conditions, sewage can be directly discharged into the municipal sewer or the centralized sewage treatment system of the campsite through pipelines, achieving direct sewage treatment.

Mobile sewage tank type: The toilet is equipped with a detachable sewage tank at the bottom. When full, it is taken out by the user and poured into public toilets, gas stations, or designated sewage disposal facilities, which is convenient and flexible.

Packing type: Feces are compressed into blocks and stored in the toilet tank, while sewage is discharged through drainage pipes, reducing the volume of waste and facilitating subsequent treatment.

Microbial degradation type: Microbial flora are used to decompose feces into water, carbon dioxide, and a small amount of residue, achieving natural degradation of waste, which is environmentally friendly and efficient.
