The invention relates to the technical field of rural
sewage treatment, and discloses an underground rural
sewage treatment device. The underground rural
sewage treatment device comprises an
enclosure, wherein the
enclosure is embedded under the ground; a
hydrolysis acidification tank is fixedly mounted at the bottom of an inner cavity of the
enclosure; a reaction tank, an anaerobic tank, an anoxic tank, an aerobic tank, a
precipitation tank and a disinfection tank are successively arranged on the right side of the hydrolytic acidification tank; the bottoms of the reaction tank, the anaerobictank, the anoxic tank, the aerobic tank, the
precipitation tank and the disinfection tank are all fixedly connected with the bottom of the inner cavity of the enclosure. According to the underground rural
sewage treatment device, a floor drain, a
water collection box and a flow guide
pipe are used for collecting rural ground surface sewage; a filtering
pipe is used for conveying the ground surfacesewage into the
hydrolysis acidification tank, so that the rural ground surface sewage can be conveniently collected and treated, and the
pollution to the environment caused by free flowing of the ground surface sewage is avoided; the reaction tank, the anaerobic tank, the anoxic tank, the aerobic tank, the
precipitation tank and the disinfection tank are used for jointly treating the sewage, andthe rural
sewage treatment efficiency of the device can be favorably improved.
