（1） Efficient processing capability
The integrated sewage treatment equipment has excellent performance in removing organic matter from sewage, with BOD (biochemical oxygen demand) removal rate usually reaching over 90%, and some advanced equipment can even reach 95% or more. At the same time, its removal effect on suspended solids is also very significant, and the SS (suspended solids) removal rate can generally reach over 95%. This means that the wastewater treated by the equipment has been greatly purified, meeting strict discharge standards and effectively reducing environmental pollution.
（2） Strong resistance to impact loads
The contact oxidation tank inside the equipment adopts a special design, and its packing generally has a large specific surface area, which can provide abundant attachment and growth space for microorganisms. When there are significant fluctuations in sewage quality and quantity, microorganisms can quickly adapt to environmental changes and maintain stable treatment effects. For example, in some industrial enterprises, intermittent drainage may occur during the production process, resulting in significant changes in sewage quality and quantity in a short period of time. Integrated sewage treatment equipment, with its strong ability to withstand shock loads, can still ensure stable and compliant effluent quality.
（3） Flexible installation method and small footprint
The integrated sewage treatment equipment has extremely high flexibility in installation, which can be installed on the ground or buried underground. For places with high requirements for ground space utilization, such as residential and commercial areas in urban centers, buried installation methods are particularly suitable. After the equipment is buried underground, the upper soil cover can be used for greening, construction of parking lots or other ground facilities, greatly saving land area. Generally speaking, its land area is only 1/3 to 1/2 of traditional sewage treatment processes, and in some cases can even be as low as 1/10.
（4） Automated operation and convenient management operations
Integrated sewage treatment equipment is usually equipped with advanced PLC control systems and various sensors, which can monitor and automatically regulate the operation status of the equipment in real time. Real time collection of sewage flow rate, water quality indicators (such as COD, ammonia nitrogen, pH value, etc.) through sensors, and transmission of these data to the PLC control system. The PLC control system automatically adjusts the operation of equipment such as aeration, dosing, and drainage according to preset programs and parameters, achieving fully automated operation without the need for dedicated personnel. At the same time, operation and maintenance personnel can also remotely monitor the operation of equipment through mobile apps or computer terminals. Once equipment malfunctions or water quality abnormalities occur, the system will immediately push alarm information for timely processing, greatly improving equipment management efficiency and stability.
（5） Lower operating costs and less sludge production
In terms of energy consumption, the integrated sewage treatment equipment adopts an efficient and energy-saving aeration system and optimized biological treatment process. Compared with traditional sewage treatment equipment, energy consumption can be reduced by 30% to 50%. Moreover, due to the strong sealing of the equipment, reasonable internal structure design, and low failure rate, daily maintenance work mainly focuses on regular inspection of consumables, cleaning and maintenance of equipment, etc. The annual maintenance cost can be saved by more than 40% compared to traditional equipment. In addition, the amount of sludge generated by the equipment during the sewage treatment process is relatively small, for example, the amount of sludge generated by the biofilm process is only one-third of that of the traditional activated sludge process. This not only reduces the difficulty and cost of sludge treatment, but also reduces the risk of secondary pollution to the environment caused by improper sludge disposal.
