Ecological filter filling system capable of replacing substrates and treating rural domestic sewage

Technical Field

The utility model relates to a sewage treatment technical field, concretely relates to ecological filtering pond filling system of rural domestic sewage of processing of removable matrix.

Background

Rural domestic sewage has become an important pollution source of regional water environment in China. Due to wide rural distribution and dispersed living, the construction of the sewage collecting pipe network in the rural areas is still lagged behind at present, the sewage treatment rate of the villages and the towns is extremely low, and most of sewage is directly discharged into the surrounding water body without being treated, thereby causing serious harm to the ecological environment. The ecological filter tank is an artificial ecosystem built by simulating the soil infiltration and self-purification processes of a natural ecosystem. Particulate matter and soluble pollutants in the sewage are intercepted and purified through a matrix filled in the system and a biological film formed on the matrix. The ecological filter tank has the characteristics of small tank capacity, energy conservation, easy operation, convenient maintenance and management and the like, and is suitable for treating rural domestic sewage which is difficult to collect in a centralized manner.
