Distributed sewage treatment device and method suitable for country

Abstract

The invention provides a distributed sewage treatment device and method suitable for the country. The distributed sewage treatment device comprises a grille water collecting well unit, an anaerobic pool unit, a combined biological filter unit and an active biological filter bed unit. The grille water collecting well unit is used for balancing the water quality and water amount of sewage to be treated and includes a water collecting well, a grille hopper and a sewage pump. The anaerobic pool unit is used for conducting hydrolytic acidificationon on the sewage to be treated and includes an anaerobic pool, a water passing weir and anaerobic filler. The active biological filter bed unit comprises a settling pond, a water collecting pipe, a holed screen, coarse filler, fine filler, a screen hopper, an active biological filter bed and an inspection well. The sewage pump, the active biological trickling filter and the active biological filter bed are integrated, a sewage pipeline is directly guided into the device without additional building construction, and the device is more suitable for a rural area in construction and usage.

Description

technical field [0001] The invention belongs to the technical field of rural environmental protection, relates to a rural decentralized sewage treatment technology, and in particular relates to a decentralized sewage treatment equipment and method suitable for rural areas.
