This paper discussed the engineering design and process selection of a rural domestic sewage treatment project in Hebei Province. It is pointed out that the rural sewage treatment should be treated by different strategies according to local conditions on the basis of ensuring the technical feasibility and economic rationality, to ensure that the effluent quality meets the discharge standard. It also briefly analyzed and summarized the common problems existing in the current rural domestic sewage treatment, including the lack of sewage treatment facilities, the collecting difficulty of sewage system, and the large fluctuation of water quality and quantity.
