In daily work, it is necessary to maintain and repair the buried sewage treatment equipment after using it. Below, the editor will talk about the maintenance precautions for buried sewage treatment equipment.

1、 It is necessary for the pH value of the sewage entering the geographic sewage treatment equipment to be between 6-9, as acidic and alkaline conditions can affect the normal growth of biofilms;

2、 It is necessary to pay attention to the absence of large solid substances in the sewage entering the equipment, in order to avoid blocking the pipes and holes and damaging the water pump;

3、 The fan usually needs to change the oil once after running for about 6 months to improve its service life;

4、 It is necessary to cover the manhole of sewage treatment equipment to prevent accidents or large solid substances from falling in

5、 It is necessary to ensure that the fan inlet of the sewage treatment equipment is unobstructed.

Refer to the device diagram for preparation. When lifting, check whether the inlet and outlet directions are correct, and the orientation and direction of the tank body cannot be placed incorrectly. The spacing between them should be accurate. After the product is lifted into place, the levelness should be measured. If it is uneven, it should be adjusted to make it horizontal. After hoisting in place, connect the pipelines and inject clean water into the equipment to check for leaks in each pipeline. Connect the control line of the electrical control box to the aerator and water pump, and connect the electrical control box to the power supply. When wiring, pay attention to the direction of the motor and fan, and it is necessary to be in the same direction as the indicated direction. After the backfilling is completed, install above ground dosing and disinfection equipment, as well as electrical control cabinets. After the equipment installation is completed, it is necessary to first connect the supporting water pipes and wires of the buried electrical equipment and dosing equipment on the ground.

Precautions for backfilling after the completion of the device: Before backfilling, fill the product with water to 1/2 of the water level, and then backfill. It is definitely not allowed to backfill with sludge to prevent the product from floating up. The backfilling soil should follow the requirement of waterless backfilling. When backfilling soil, it is necessary to manually fill both sides of the bottom of the product. When filling to 30-50cm or more, it is necessary to compact every 30cm until it is level with the top of the product. It is necessary to compact the backfill soil above the top of the product. If the product is located in a road area, vehicles are not allowed to roll it before ground treatment; The quality of backfill soil must comply with the acceptance standards for backfill soil. Construction waste is definitely not allowed to be used as backfill soil. Sharp corners, stones, and hard debris in the soil must be removed. When backfilling, it is necessary to backfill evenly and avoid strong local impacts.

After the backfill soil meets the construction specifications, the inlet connection well (about 0.8-1m away from the pool) should be built. The bottom layer of the well should be compacted and a concrete bottom plate should be poured. A flow channel should be made in the well, and the engineering design elevation should be strictly followed. That's all for this episode's introduction.
