How Container Houses Drain Waste

Container houses typically achieve waste drainage through bottom drainage structures or integrated sewage treatment systems, with specific designs varying based on the type of house and functional requirements.

I. Waste Drainage via Bottom Drainage Structures

Some container houses use bottom drainage structures for waste drainage, with typical designs including:

1. Combination of Perforated Plates and Inclined Plates: The bottom of the container is equipped with perforated plates, support rods, and inclined plates from top to bottom. The perforated plates are used to filter sand, gravel, and flocculent materials. The support rods are hinged at the bottom of the perforated plates, and the inclined plates have an inclination angle of less than 30 degrees, with the bottom of the support rods touching the top of the inclined plates. After being filtered by the perforated plates, the sewage flows along the inclined plates to the lower side.
2. Inlet Pipes and Drainage Outlets: Inlet pipes are installed on the outer wall of the container near the higher side of the inclined plate to introduce sewage, while drainage outlets are installed on the lower side. A sealing plate with drainage holes is mounted on the drainage outlet to discharge the filtered sewage.
3. Anti-Clogging Design: This structure prevents sand, gravel, and flocculent materials from clogging the drainage system through physical filtration and gravity drainage, ensuring smooth drainage.

II. Waste Drainage via Integrated Sewage Treatment Systems

Some container houses achieve waste drainage through integrated sewage treatment systems, with typical designs including:

1. Solar Water Heater Supply: Container houses are equipped with solar water heaters to provide domestic water (such as for showering and washing). The sewage flows into the sewage treatment system through pipes.
2. Sewage Treatment System Purification: After being purified by the treatment system, the sewage can be reused (such as for flushing toilets and irrigation), reducing water waste.
3. Independent Sewage Drainage Interfaces: Some container houses (such as those used as observation points in enterprises and institutions) are equipped with independent sewage drainage interfaces, facilitating connection to external sewage pipes for direct sewage discharge.

III. Other Waste Drainage Designs

1. Bathroom Function Boxes: Some container houses are equipped with bathroom function boxes that integrate toilets, sinks, and other facilities. The sewage is discharged through concealed wire troughs and drainage slopes, ensuring both airtight and watertight seals.
2. Rainwater Harvesting Systems: Some container houses are designed with rainwater harvesting systems to use rainwater for non-potable purposes (such as flushing toilets and cleaning), reducing reliance on municipal water supplies.
