Domestic sewage treatment device

Abstract

The invention relates to a domestic sewage treatment device. The domestic sewage treatment device comprises a box body, wherein the box body is successively divided into a primary precipitating box, astirring box, a biological contact oxidation box and a disinfection box by partition plates from the left side to the right side, wherein the primary precipitating box comprises a precipitating box and a sludge box; a water inlet is formed in the left side of the precipitating box; a top cover is arranged at the top of the precipitating box; a grid is arranged in the precipitating box and is horizontally placed in the inner cavity of the precipitating box; the precipitating box is communicated with the sludge box; a stirring device is arranged in the stirring box and is mounted at the bottomof the stirring box; a biological filtering bed is arranged at the bottom of the biological contact oxidation box; an ozone generator is fixed above the disinfection box; a purification device is arranged in the disinfection box; a water outlet pipe is arranged on the right side of the disinfection box. Through the domestic sewage treatment device, the emission of the sewage in the cities is greatly reduced; the water resource for living can be recycled; the water resource can be saved; meanwhile, the environment is protected; the living costs of people are also reduced.
