According to the invention, rural domestic sewage, residential domestic sewage or a small amount of industrial wastewater are collected, then enter a pretreatment area through a lifting system for coagulation sedimentation and anaerobic and anoxic processes in the pretreatment area, and automatically flow into a MBR area after pollution indexes meet the water inflow requirement of an MBR system; through the treatment in the MBR area, the turbidity of produced water is less than or equal to 1 NTU, and other indexes conform to produced water quality indexes of the MBR system. Photocatalytic oxidation produced water enters a water producing area and can be overflowed and discharged, and can also be sent to a recycling point through a pressurization system for recycling. The traditional process, the film process and the advanced oxidation process are organically combined to form a movable integrated water treatment device aiming at small water quantity, the system has high automation degree, is unattended, does n
