The invention relates to the technical field of sewage treatment, in particular to an integrated treatment device and method for domestic sewage in ports, wharfs and rural areas, at least two biochemical treatment chambers and a settling chamber are arranged in a sewage treatment tank, and meanwhile, a disinfection reservoir is arranged at a water outlet end, so that the domestic sewage is adjusted and buffered by a flow adjusting chamber, and then the sewage is discharged into the settling chamber. The sewage enters the biochemical treatment chamber in an overflow manner, is subjected to multi-stage biochemical treatment and then overflows into the settling chamber, so that the whole sewage treatment process is accompanied by a physical settling process, pollution particles suspended in water can be removed to a great extent, and the sewage treatment effect is improved by performing disinfection treatment on the settled disinfection water storage tank; the treated purified water can be used for urinal flushi
