Advantages of p>LTLD buried integrated sewage treatment equipment:

1. It is buried below the surface, and the surface above the equipment can be used as greening or other land, without building, heating and heat preservation.

2. The two-stage biological contact oxidation process adopts plug-flow biological contact oxidation, and its treatment effect is better than that of fully mixed biological contact oxidation tank or two-stage series fully mixed biological contact oxidation tank.

3. The deodorization method of buried domestic sewage treatment equipment is equipped with soil deodorization measures in addition to conventional high-altitude exhaust.
