Hospital sewage treatment equipment, sewage treatment process selection:

（1） Select the process based on the scale, nature, and discharge direction of the hospital outpatient department. According to the classification of hospital outpatient services, they are divided into infectious disease hospital outpatient services and comprehensive hospital outpatient services. The discharge direction of hospital outpatient sewage treatment is divided into two categories: discharging into natural water bodies and discharging into urban sewage treatment plants through municipal sewers.

The process used for outpatient sewage treatment in hospitals must ensure that the treated effluent meets the standard. The three main processes used are: primary treatment to enhance treatment effectiveness, secondary treatment, and simple biochemical treatment. The principle of process selection is:

1. Outpatient departments of infectious disease hospitals must adopt secondary treatment and undergo pre disinfection treatment.

2. Outpatient departments of hospitals at or above the county level that discharge treated water into natural water bodies must adopt secondary treatment.

3. The outpatient department of a comprehensive hospital that discharges treated water into the urban sewer (with a secondary sewage treatment plant downstream) adopts secondary treatment, and the treatment effect must be strengthened for those that use primary treatment technology.

4. For outpatient clinics in small comprehensive hospitals in economically underdeveloped areas, simple biochemical treatment can be used as a transitional measure when conditions are not available, and then gradually achieve secondary treatment or primary treatment with enhanced treatment effects.

（2） Considering the above principles, the hospital outpatient sewage treatment process designed in this scheme is compared based on the application of different treatment processes

With the continuous development of sewage treatment technology, the commonly used processes developed in recent years both domestically and internationally include:

1. Primary processing technology to enhance processing effectiveness

For the outpatient department of a comprehensive hospital where the treated effluent finally enters the secondary treatment urban sewage treatment plant, its treatment effect should be strengthened, the removal rate of SS should be improved, and the amount of disinfectant used should be reduced. There are two ways to enhance the effectiveness of primary treatment: modifying the existing primary treatment process to improve removal efficiency and adopting primary strengthening treatment technology.

INSTALLATION REQUIREMENTS

1. According to the installation diagram and foundation diagram of the hospital sewage treatment equipment, prepare the foundation based on the size and dimensions of the installation plan, and prepare a concrete base plate. The foundation requires an average bearing capacity of 5t/m2, and must be horizontal. The installation can only be carried out after the maintenance period of the concrete foundation pouring is over. If the equipment is installed below the floor, the relative elevation of the foundation from the floor shall be based on the dimensions in the diagram. At the same time, the excavation width and length around must be at least 500mm away from the foundation edge for pipeline installation.

2. The installation and connection of pipelines should be considered when the equipment is in place. When the equipment is in place, it must be installed according to the self weight of the equipment in the instruction manual, in accordance with the tonnage size of the crane. The installation sequence should be in place according to the on-site reference diagram. The position and direction of the cylinder must not be placed incorrectly, and the spacing between them must be correct.

3. According to the installation diagram, connect the pipes and secure them with rubber pads after the equipment is in place to prevent leakage at the connection point.

4. After the installation of buried sewage treatment equipment, the equipment must be connected and fixed to the foundation floor to ensure that the equipment does not flow and float. At the same time, sewage must be injected into the equipment (when there is no sewage, other water sources or tap water should be used instead), and the filling degree must reach 70% or more to prevent the equipment from floating. At the same time, check for any leaks in each pipeline. The intersections of each water testing pipeline must not leak, and the equipment must not be displaced or tilted due to the rise of surface water.

5. After the installation of the equipment is completed without any issues, soil can be filled around the equipment and compacted in the gaps. When leveling the ground and filling the soil, attention should be paid to:

(1) The manhole cover plate of the equipment must be about 50mm higher than the floor;

(2) Do not allow soil to block the air inlet on the manhole cover plate.

6. Connect the control line of the electrical control cabinet to the equipment, and pay attention to the direction of the underwater aerator and submersible sewage pump motor when wiring. For example, the basement control cabinet should be placed in a ventilated area and kept dry. Generally, the control cabinet should not be placed outdoors. Be protected from sun exposure, rain, etc. To prevent electric leakage and burning of the control board and wiring terminals.

7. Precautions for buried sewage treatment equipment:

(1) The installation location of the equipment must ensure that there is no water accumulation during rain;

(2) The outlet pipe of the equipment must be below 0.4m relative to the ground level;

(3) There shall be no heavy objects or large vehicles passing over the equipment (referring to those without special design);

(4) Equipment should generally not be emptied of internal sewage to prevent groundwater from causing the equipment to float.

8. Please note that the installation diagram and pipeline connection diagram of this equipment should be connected and arranged according to the standard plan. If requested by the user, they can be arranged arbitrarily, but they must be mentioned when signing the contract.

9. Connect the control circuits of the fan and water pump, and pay attention to the correct direction of rotation of the fan and water pump.
