Modularized river sewage treatment device

A modularized river sewage treatment device comprises a water inlet device, a first ozone contact tank, an aerobic biological filter tank, a second ozone contact tank, a discharge monitoring tank and a water outlet device which are communicated in sequence, a PH adjusting device is arranged in the first ozone contact tank, the aerobic biological filter tank is filled with microorganism curing filler, and the second ozone contact tank is filled with microorganism curing filler. An independent activated carbon filter tank is arranged in the second ozone contact tank. The sewage treatment device adopts an ozone oxidation method to treat river sewage which is difficult to degrade, the oxidation performance of the sewage can be remarkably improved, and on the premise that the pH value of the sewage is easy to adjust, a good treatment effect can be achieved by adopting a process route of ozone oxidation-aerobic biological filtration-ozone oxidation to treat the river sewage. 一种模块化的河流污水处理装置，包括依次相连通的进水装置、第一臭氧接触池、有氧生物
