Renovation of Toilets in New Countryside —— Water-free Squatting Toilet in Dry Toilet

The dry sealed toilet is characterized by 1, and no water is needed at all. The working principle is that feces and urine are collected and stored separately, and then the feces are covered with plant ash for drying and dehydration, so that the feces are harmless.

Characteristics of dry sealed toilets II. Excellent cold resistance. The working principle is to kill pathogens and eggs by physical methods of drying and dehydration, rather than biological fermentation. Even at low temperature, feces can still be effectively treated.

Characteristics of dry sealed toilets. It is convenient to clean toilet feces. The urine collected separately can be directly used as fertilizer, and the dried feces can be treated into massive solids, and the smell disappears, which is convenient for cleaning, and can also be used as a soil improver.

Materials needed for new dry sealed dry latrines in rural areas: We take a sanitary dry latrine in a toilet pit as an example, which requires about 1200 bricks, 3 bags of cement and 0.3 cubic meters of sand and gravel. There are 1 dry sealed urinals, 1 urine storage barrel, 1 cover plate, 1 drying plate, 1 exhaust pipe, 1 urination pipe, 1 impermeable plastic plate, doors and windows.

The new rural dry-type sealed aqua privies mainly achieve harmless effect through dehydration and drying. It is the key to the normal use of the toilet to prohibit entering the toilet pit and keep it dry. First of all, before the new toilet is used, sprinkle a layer of grass sawdust or lime on the bottom of the toilet pit, or use dry dust in the yard. In addition to absorbing moisture and odor, this layer of material can mainly provide microorganisms that decompose feces and accelerate the speed of harmless treatment. Also pay attention to adding ash after defecation, and the amount added is 2-3 times that of feces. Different covering materials have different harmless effects on feces, among which plant ash has the best effect, followed by furnace ash, sawdust, loess and quicklime. Secondly, if the dry sealed toilet pollutes feces, don't rinse it with water, but wipe it with a wringing mop.
