How to design a rural toilet without odor in the yard?

Considering the relatively large rural residential area and non-mandatory surrounding environment:

1. Squat pit design can be adopted in the hospital, with septic tank opening and small door outside the courtyard wall;

2. Ensure that the toilet in the hospital is ventilated, and it is best to ventilate both sides accordingly, which will help to increase air circulation and play a good role in ventilation. Specifically, you can make a window on this side of the yard. The glass is frosted glass and opaque. You can open a round mouth 2 meters to 2.5 meters near the outer wall of the courtyard and press a natural wind to exhaust fans or gauze;

3. Open the window for ventilation after going to the toilet every time, clean the septic tank regularly, and close the septic tank door on the wall in case of heavy wind and rain;

Remember that ventilation is the most important thing.
