Background
The rural areas have diversified toilet types and obvious difference of toilet construction levels, and most of the rural areas mainly use dry toilets. Farmers have the traditional method of preparing agricultural fertilizers by directly composting excrement. Furthermore, the rural areas have the tradition of combining the dry latrine with the cultivation, namely human excrement is used as the feed of the pigs and sheep. Pigs are housed underground, and meanwhile, a dry latrine is built on the ground. Leading to a series of problems of foul smell, numerous mosquitoes and flies and the like in rural dry latrines.
At present, the rural toilet is transformed into the existing form comprising: dry-sealed toilets, three-grid septic tanks, triple biogas tanks, double-vat funnel type or double-pit alternating toilets. However, the toilets in the forms do not fundamentally solve the problems of the dry toilets. No sterilization measures are taken; no deodorizing measures; the volume of the excrement is increased by flushing with water, and the decomposition difficulty is increased; more seriously, accidents frequently occur in the anaerobic fermentation process, and people are often harmed by the outbreak of methane. The water consumption of the flushing toilet is high, a sewer pipe network and a sewage treatment facility matched with the flushing toilet are needed, and the current small-sized drainage and sewage treatment facility suitable for rural areas is more expensive than the large-sized facility in cities, so that the construction cost and the operating cost of the flushing toilet are higher.
