(1) Low investment and operating costs. Integrated sewage equipment requires low investment and is easy to operate and manage. There is no need to train operators and only needs timely maintenance. Therefore, the operating costs are also very low.

       (2) saves space. The equipment is small in size, space-saving and flexible in operation. Some equipment can also be buried underground and does not occupy ground area.

       (3) delays the construction of urban drainage pipe networks. A complete urban drainage pipe network is a basic condition for normal operation. In areas where the population is concentrated and the centers are generally far away, it is impractical to build a drainage pipe network, which provides application space for comprehensive equipment. After treatment byintegrated sewage equipment, it can be discharged directly into nearby accepted waters without centralized collection and treatment through the drainage pipe network, which greatly reduces the pressure on the construction of municipal sewage pipe networks.

       (4）污水再利用。一般情况下，污水回用系统比较复杂，管网规模大，管理维护困难。integrated sewage equipment不用安装大规模的管网系统，可灵活地无节点回用污水，具有较大的优势。
