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. Background technique [0002] The rural sewage treatment project is an important way to implement the scientific concept of development, promote the construction of "two-oriented society", and complete the task of reducing major pollutants. In the process of rural sewage treatment, we need to strengthen the goal of pollution prevention and control according to the guidelines of comprehensive promotion and key breakthroughs, and strive to achieve effective goals after the implementation of the project, which can effectively solve the current prominent rural non-point source pollution environmental problems. The rural sewage treatment project is an important foundation for actively implementing the rural wel...
