The purpose of the research is to meliorate the situation of the rural residents who have difficulties in bathing and
poor personal hygiene in the poverty-stricken areas of Hebei Province, improve the living standard of rural residents
and reduce the environment pollution. We select the rural residents in a typical poverty-stricken village of Taihang
Mountain Area in Hebei province as research objects. Through field investigation, questionnaires and detailed interviews,
we learned the actual needs of the residents for bathing and finds that the main difficulty in bathing is that
the residents cannot afford the independent bathing facilities because of poverty. After investigation, comparison
and reference of the bathing methods and the various sustainable energy, we select the solar energy and biogas as a
combined energy supply. Moreover, we bring out the design of a reasonable, sustainable and convenient service system.
It can improve the sanitary condition of rural residents and provide a new solution to improve the quality of
life of rural residents and reduce rural environmental pollution.
