The basic structure of dry-sealed rural toilets consists of toilet rooms, dry-sealed urinals, men's special wall urinals, urine diversion pipes, urine storage tanks, manure storage tanks, exhaust pipes and drying plates. ?

Dry-sealed urinal: the dry-sealed urinal (seat) has two outlets, the front part is small, which is convenient for urination, and the inner diameter of the urination outlet is not less than 50㎜, and the lower end is connected with a urination pipe to collect urine and a urine storage tank; The big mouth at the back end is used for excreting excrement, and the inner diameter of the excrement outlet is not less than 160- 180mm, and it is connected with the excrement storage tank.

Dry sealed toilet cesspool: built on the ground, underground or semi-underground according to the groundwater level. A single dunghill is not less than 0.8m? Suggested length is 1200mm and width is1000; The recommended length of double storage septic tank is 1500㎜ and the height is 800㎜. The effective volume of each tank should not be less than 0.5m? . ?

Dry sealed toilet exhaust pipe: an exhaust pipe should be installed at the upper end of septic tank, which is at least 500㎜ higher than the toilet roof, and a rain cap (fly-proof, wind-proof, etc.) should be added. ) it should be fake?

Dry seal toilet to avoid flushing: the way to make toilet harmless is to cover it and dehydrate it. Require complete separation of feces and urine to avoid flushing. Dry ash after defecation (plant ash, furnace ash, yard soil, etc. ) added to the cesspit, the dosage is more than the amount of feces, until the cesspit remains dry. The covering time of plant ash is not less than 3 months, and the covering time of furnace ash and loess is not less than 10 month.
