Technical Field

The utility model relates to the field of rural sewage treatment, in particular to a rural domestic sewage treatment device.

Background

Most village residents can directly pour sewage into the ditches in front of the doors for convenience, so that the village environment and fresh water resources are polluted. The rural domestic sewage treatment problem needs to be solved urgently, especially the residential houses in mountain areas are scattered, and the sewage treatment pipeline is high in laying cost. For the village where residents are scattered, the common domestic sewage centralized treatment mode is not suitable, and the scattered treatment mode is often adopted. Common sewage treatment equipment is only provided with a filter layer, or sewage is stored and discharged in the same way. In view of the above-mentioned related art, the inventors consider that most of the existing sewage treatment apparatuses have difficulty in completely treating sewage, so that a small-sized rural domestic sewage treatment apparatus which is convenient and practical and can be realized from home to home should be designed.
