1. Product Introduction
The containerized integrated sewage treatment plant is a compact, skid-mounted, fully packaged decentralized wastewater treatment solution designed for domestic sewage treatment in rural towns, residential communities, scenic spots, service stations, construction camps and public facilities. All treatment units, pipeline systems, aeration equipment, automatic control and disinfection devices are completely integrated inside a standard container. The whole plant is factory prefabricated, fully assembled and tested before delivery, requiring no large-scale civil construction on site. With the advantages of convenient transportation, fast installation, unattended operation and stable effluent quality, it is highly suitable for various temporary and permanent sewage treatment projects, especially for overseas export projects and areas with limited construction conditions.
This equipment is mainly applied to treat daily domestic sewage, effectively removing COD, BOD5, ammonia nitrogen, total phosphorus, suspended solids and other pollutants. The effluent can steadily meet national and international discharge standards and can be reused for greening irrigation and site water supply, realizing environmentally friendly and recycled water resource utilization.
2. Technological Process
The containerized sewage treatment system adopts a mature and optimized biological treatment process with stable operation and strong impact resistance. The complete treatment flow is as follows:
Raw Water Inflow → Mechanical Grid → Regulation Tank → Anaerobic Hydrolysis → Anoxic Denitrification → Aerobic Biological Oxidation → Sedimentation → Disinfection → Standard Discharge / Reuse
First, the mechanical grid removes large floating impurities and suspended debris to protect subsequent equipment. The regulation tank balances water quantity and water quality fluctuation caused by centralized water consumption and seasonal changes. In the anaerobic and anoxic stages, macromolecular organic matters are decomposed, and denitrification is completed to remove total nitrogen. The aerobic tank utilizes high-efficiency microbial flora to degrade organic pollutants, COD and ammonia nitrogen efficiently. After solid-liquid separation in the sedimentation area, the clean water is disinfected to eliminate harmful bacteria, finally achieving stable and standard discharge. A small amount of sludge is automatically discharged and regularly cleaned, ensuring long-term stable system operation.
3. Core Technical Features
1. Standard Container Integrated Design, Easy Transportation and Fast Deployment
The whole system is built in a standard container structure, featuring high structural strength, shock resistance and compression resistance. It is fully adapted to long-distance sea transportation and overseas project delivery. The container is waterproof, dustproof, sun-proof and anti-corrosive, capable of stable operation under complex climates such as high temperature, humidity, low temperature and salt fog. On-site installation only requires foundation leveling, pipeline connection and power access, which greatly shortens the project construction cycle.
2. No Complicated Civil Works, Low Project Investment
Different from traditional sewage treatment stations that require a large amount of concrete construction, the containerized integrated plant realizes full factory prefabrication. It needs no complex civil engineering, reduces project cost and site occupation, and is especially suitable for sites with limited space, tight construction period and poor infrastructure conditions.
3. Stable Treatment Effect and Strong Anti-impact Load Capacity
Optimized for the characteristics of domestic sewage with fluctuating water volume and unbalanced water quality, the system maintains high biological activity and stable sludge flora. It can effectively cope with peak water inflow, intermittent water inflow and seasonal water quality changes, avoiding system paralysis and unstable effluent problems. The effluent quality remains stable all year round.
4. Intelligent Automatic Operation, Unattended and Low Maintenance
Equipped with a complete PLC automatic control system, the equipment realizes full-process automatic operation including water inlet, aeration, circulation, sedimentation and disinfection. Remote monitoring and fault early warning functions are optional. The system runs 24 hours a day with low failure rate and minimal sludge production. Daily operation only requires simple regular inspection, without full-time professional operators, greatly saving labor and management costs.
5. Low Energy Consumption and Low Operating Cost
Adopting high-efficiency energy-saving aeration and optimized hydraulic circulation design, the equipment improves oxygen utilization rate and reduces power consumption per ton of water. With fewer vulnerable parts and simple maintenance, the overall life-cycle operating cost is far lower than that of traditional sewage treatment equipment, achieving low-cost and high-efficiency sewage purification.
6. Fully Sealed and Environment-Friendly, No Secondary Pollution
The whole container adopts a fully sealed structure with no sewage leakage or odor overflow. The operation noise is low, and the sludge output is small, which will not affect the surrounding living and ecological environment. It can be installed close to residential areas, scenic spots and public facilities, meeting high-standard environmental protection requirements.
