Abstract: Abstract: The Toilet Revolution is closely related to people's livelihood, well-being, and welfare. The renovation of rural toilets has been one of the most important parts to realize Rural Revitalization. In this review, a systematic investigation was made to sort out the existing challenges during rural toilets renovation in China. Some issues were also covered, including the inadequate implementation of toilet-renovation policies, blind selection of toilet types, improper treatment of fecal sewage, and imperfect toilet standards. Three aspects were reviewed in the development of rural toilet renovation: the development process of toilet renovation policies, the key technologies (such as the types of sanitary toilets and fecal sewage treatment), and the standard system of toilet renovation. There was the continuous updating and introduction of policies and regulations in the process of toilet renovation in recent years. The toilet reconstruction was a high urgency to fully meet the requirements of the country for the sanitary toilets in Rural Revitalization. It is necessary to comprehensively promote the improvement of rural human settlements. The farmers' concept of environmental health also needed to build a well-off society in an all-round way. Alternatively, a summary was made for the types of sanitary toilets and the process of harmless treatment of fecal sewage, according to the key technologies of toilet renovation. There were six types of sanitary toilets renovation in the rural areas in China at present. Specifically, three-compartment septic tank, double-urn funnel, triple, feces and urine separation, double-pit alternating, and complete sewer flush type toilet. Furthermore, it was also summarized to gradually develop and popularize the new ecological toilets in rural areas. Therefore, the characteristics of sanitary toilets were evaluated to choose the specific types of toilets suitable for the local situation and the requirements of farmers in different areas. At the same time, the treatment of toilet feces was also an urgent problem to be solved. The abandonment of the reconstructed toilet and waste of resources also posed a major threat to human health and the ecological environment. An optimal treatment mode was selected for the faecal sludge to balance the local conditions, the types of sanitary toilets, and the requirements of farmers. Besides, it was also essential to treat the faecal sludge in a harmless, reduced and resource-based manner. According to the standard system of rural household toilets, the current standards, specifications or technical requirements were also summarized for the reconstruction of rural toilets in China. Different levels were classified during this time. However, it was still lacking in the system and integrity in the standards and specifications. Thus, a systematic standard system needed to be issued in the future. Finally, some suggestions were recommended for the policy regulations to implement in place, the technologies and models to select suitable for the local conditions, and a systematic rural household toilet standard system to formulate. It is also necessary to further strengthen departmental coordination and operation management. The finding can also provide a strong reference to promote the rural toilet revolution in China.
