Integrated Sewage Treatment Plant

1. Multi-process integrated processing

It integrates the functions of bar filtration, water quality adjustment, biochemical degradation, sedimentation and separation, disinfection and sterilization, and can treat domestic sewage, small and medium-sized industrial organic wastewater and livestock manure in one stop without the need to build separate treatment facilities.

2. Highly efficient removal of pollutants 

By degrading organic pollutants such as COD, BOD, and ammonia nitrogen in wastewater through biochemical reactions, and removing suspended solids through sedimentation and filtration processes, the effluent quality can meet the national Class I discharge standard or reuse standard.

3. Fully automatic intelligent 

operation Equipped with liquid level and water quality sensors and a PLC control system, it can automatically start, stop and adjust processes such as water intake, aeration, sludge discharge and disinfection without the need for dedicated personnel, thus reducing manual operation and maintenance costs.

4. Sludge reduction treatment 

Built-in sludge return and digestion functions reduce sludge production, lower sludge transportation and disposal costs, and prevent secondary pollution.

5. Flexible adaptation and reuse 

The core processes such as MBR/MBBR/SBR can be flexibly configured according to the wastewater quality. The effluent can be discharged directly or used for reclaimed water utilization such as farmland irrigation, greening watering, and road washing.

I. Media Requirements 

1. Applicable wastewater: Domestic sewage, small and medium-sized industrial organic wastewater, and livestock manure. 

2. Parameter range: COD≤500mg/L, BOD≤300mg/L, SS≤200mg/L, pH 6-9 

3. Contraindications: Strictly prohibited for treating wastewater containing heavy metals, highly toxic substances, high salinity (>5%), or flammable and explosive materials.

II. Installation and Operation Conditions 

1. Temperature: Operating temperature 5℃~40℃ (insulation required for low temperatures, shading required for high temperatures); Storage temperature -10℃~50℃. 

2. Site: Flat, hardened ground with a load-bearing capacity ≥ 1.2 times the total weight of the equipment; ≥ 0.8m maintenance access provided; well-ventilated and away from open flames. 

3. Electrical: AC380V/220V, 50Hz/60Hz; outdoor installation with rainproof distribution box; electrical protection ≥ IP54.

III. Adaptation to Special Scenarios 

1. Buried type: Requires foundation pit seepage prevention, ventilation and drainage. 

2. Mobile type: Suitable for temporary construction sites and emergency rescue; can be equipped with a generator. 

3. Cold regions: Requires additional insulation layer + pipe heating cable.

1. Integrated design, small footprint

It integrates the functions of bar screen, biochemical treatment, sedimentation and disinfection, without the need for separate structures, and occupies only 1/5 of the space of a traditional sewage treatment plant, making it suitable for scenarios with limited land, such as residential areas and scenic spots.

2. Fully automatic operation, saving labor. 

Equipped with a PLC intelligent control system, it automatically completes water intake, aeration, sludge discharge, and disinfection without the need for dedicated personnel, significantly reducing maintenance labor costs.

3. The effluent meets standards and can be reused. 

The MBR/MBBR process can be flexibly configured to efficiently remove pollutants such as COD and ammonia nitrogen, and the effluent meets the Class A discharge standard. It can be directly discharged or used for greening irrigation and road washing.

4. Easy installation and short construction period 

The prefabricated integrated box structure in the factory only requires foundation pouring and pipeline connection on site, shortening the installation cycle to 7-15 days, which is much faster than traditional civil engineering sewage treatment plants.

5. Reduce sludge volume and lower costs. 

The built-in sludge return and digestion system reduces sludge production by more than 30%, lowers sludge transportation and disposal costs, and avoids secondary pollution.

6. Flexible adaptation to multiple scenarios

It can be buried underground or installed in a mobile manner, and is suitable for various scenarios such as rural decentralized sewage treatment, hotels, hospitals, and industrial parks. It also supports customized process solutions.

1. Decentralized sewage treatment in rural areas 

It is suitable for villages and towns without centralized pipe networks, treats domestic sewage, and the underground installation does not occupy farmland. The effluent can be used for farmland irrigation and greening, contributing to the construction of beautiful villages.

2. Urban civil building sewage

It is used for domestic sewage from residential communities, hotels, hospitals, schools, and nursing homes. It can be installed directly around the building, operates fully automatically without the need for dedicated personnel, and the effluent meets discharge standards or can be reused.

3. Treatment of organic wastewater from small and medium-sized industrial plants 

For organic wastewater from industries such as food processing, slaughtering and breeding, textile printing and dyeing, and catering laundry, the MBR/MBBR process can be flexibly configured to efficiently degrade COD and ammonia nitrogen, meeting industrial wastewater discharge standards.

4. Wastewater treatment in scenic areas and service areas 

Suitable for tourist attractions, highway service areas, and camping sites, the processing load can be adjusted according to the number of tourists. The mobile model can be flexibly relocated as the scenic area expands, avoiding sewage pollution of the natural environment.

5. Municipal emergency and temporary sewage treatment 

To address the urgent repair of municipal pipelines, river dredging, and sewage overflows following floods, vehicle-mounted integrated equipment can be quickly deployed to temporarily treat sewage and prevent pollution of surrounding water bodies.

6. Ship and port sewageUsed for treating domestic sewage 

from crew members on inland waterway vessels and coastal docks, the miniaturized container is adapted to the space of the vessel. After treatment, the sewage can be directly discharged into the waterway or transferred ashore, which meets the requirements of maritime environmental protection.

I. Preparations before powering on 

1. Check pipeline valves: Open inlet and outlet valves, close sludge discharge valve; clean debris from the screen. 

2. Confirm power supply and control cabinet parameters are normal; check fan oil level and water pump for obstructions. 

3. Maintain the regulating tank level at 2/3 height to avoid starting with an empty or full tank.

II. Startup and Operation 

1. Automatic Mode (Common): Set the control cabinet to AUTO. The system will automatically complete the entire process of water intake, aeration, mixing, sludge discharge, and disinfection. Regularly check online monitoring data (COD, liquid level, etc.) to ensure compliance. 

2. Manual Mode (For Debugging/Troubleshooting): Set the control cabinet to MANUAL. Start and stop the booster pump, blower, and mixer individually according to the process sequence. Frequent switching on and off of equipment is prohibited. 

3. Caution: Overflowing water is strictly prohibited. Immediately stop the machine in case of sudden changes in water quality (strong acid or strong alkali).

III. Shutdown and Maintenance

1. Normal shutdown: In manual mode, shut down the pump, mixer, blower, and disinfection equipment in sequence; drain the sludge and clean the screen and filter. 

2. Long-term shutdown: Drain the wastewater from the equipment and clean the pipelines; disconnect the power supply and take precautions against moisture and dust; periodically run the pump/blower under no-load to prevent rust corrosion.

IV. Safety Precautions 

1. Power off and tag the equipment before maintenance. Ventilate and test for toxic gases before inspecting the inside of the enclosure. 

2. Avoid contact with disinfection devices (such as ultraviolet light or sodium hypochlorite generators) to prevent burns or corrosion.
