Container type sewage treatment equipment

1Container type sewage treatment equipmentSuitable occasions

Container type sewage treatment equipmentSuitable for domestic sewage treatment or reuse in tourist scenic areas, villa areas, residential areas, oilfield drilling teams, mining areas, gas stations, substations, stations, toll stations, highway service areas, villages, small towns, etc; Wastewater treatment or reuse at temporary construction sites; Wastewater treatment in hospitals, sanatoriums, and nursing homes.

2、 Characteristics of containerized sewage treatment equipment

1. Quick installation and use, instant connection and use. Users only need to connect the inlet and outlet pipes directly to the equipment to operate, and the water output quickly meets the standard requirements, greatly shortening the construction period;

2. The appearance relies on the container shell, which can meet the requirements of sea transportation and is easy to transport:

3. Easy to move and transport, users can change different placement locations according to their needs, and can also share a set of processing equipment in multiple places for cyclic use, saving equipment investment;

4. The treatment effect is stable and reliable, with a BOD removal rate of 98%. The effluent is clear and can be directly reused for flushing, greening, landscaping, etc. It can also be discharged to high standards, saving water and reducing emissions;

5. The footprint is more than 50% smaller than ordinary process equipment, saving land.

6. The equipment operates fully automatically, without the need for dedicated personnel or medication. It has low sludge production, easy maintenance, and saves operating costs.

7. Single device processing water volume range: 5-300 tons/day, flexible operation, equipment can adapt to the continuous fluctuation of incoming water volume;

8. The device can operate automatically based on pre edited control conditions, or be manually controlled according to user needs;

9. The treatment capacity of containerized sewage treatment units adopts single or multiple group design, and non-standard sizes can be customized according to site conditions, or container standard sizes can be used. The operation mode of containerized sewage treatment units can be divided into continuous flow and intermittent flow, with flexible operation and convenient operation;

10. The process can adopt A/O; A2/O; A3/O; A/O+MBR; Multiple combination processes such as A/O+MBBR can also be designed according to emission standards;

3、 Process flow of containerized integrated sewage treatment equipment

Container type sewage treatment equipmentThe process flow is introduced as follows:

1. Regulating pool (self built by the customer): collects and stores sewage, and regulates the water quantity and quality.

2. Lift pump: A lift pump is installed in the regulating tank to automatically lift the sewage into the AD-JZ integrated sewage treatment equipment.

3. Grille: Sewage often contains a large amount of debris. In order to ensure the normal operation of the system, various fibers, slag, waste paper and other debris must be intercepted outside the system. Therefore, a grille is set up in front of the system to regularly clean the slag.

4. Hypoxia pool: Its function is to decompose large molecules into easily decomposable small molecules, thereby increasing the B/C ratio of wastewater. In addition, denitrification can also achieve denitrification effect. This section is determined based on the quality of raw water and discharge standards.

5. Aerobic tank: This tank is the core part of this sewage treatment system, divided into two sections. In the first section, under high organic load, a large number of microbial communities of different species attached to the packing participate in biochemical degradation and adsorption, removing various organic substances from the sewage and significantly reducing the organic content in the sewage. In the later stage, under low organic load conditions, the action of nitrifying bacteria degrades ammonia nitrogen in sewage under sufficient oxygen conditions, while also reducing the COD value in sewage to a lower level, thus purifying the sewage.

6. MBR reaction tank: Adopting different structures of immersed flat membrane bioreactor (MBR) components, it is set in the aeration tank. After aerobic aeration and biological treatment, the water is filtered through a membrane (with a pore size of 0.1um) and pumped out by a pump before being directly discharged or reused. Due to its effluent not being affected by sludge settling conditions, the tank can operate under high volume load and long sludge age conditions, greatly improving the process conditions of biological oxidation, enhancing the efficiency of organic matter degradation, and eliminating the need for a secondary sedimentation tank, achieving excellent and stable effluent.

7. Disinfection: According to the requirements of the effluent, the system is designed with a disinfection device, generally using a simple and clean ultraviolet sterilization method, or a disinfectant dosing method can also be selected.

8. Supporting electromechanical equipment room: suction pumps, fans, electrical control cabinets, etc. are installed in the equipment room. The entire system operates automatically under PLC control and protects the equipment. All power equipment is used for equipment, automatically switches in case of failure, and maintains normal operation of the equipment.

4、 Advantages of containerized integrated sewage treatment equipment

1. Ordinary integrated sewage treatment equipment is welded from ordinary steel plates, with a rough appearance. The container integrated sewage treatment equipment uses ordinary steel plates inside and decorative panels outside, with a beautiful and elegant appearance.

2. The insulation effect of ordinary integrated sewage treatment equipment is poor, and the operation effect in winter is not good. The integrated sewage treatment equipment for insulated containers includes an electric heat tracing insulation system and a rubber cotton interlayer, which greatly ensures the temperature requirements during the operation of the equipment.

3. The integrated sewage treatment equipment with insulated containers can adapt to extremely cold weather in the north.
