Filter cartridge for domestic wastewater treatment

摘要

The utility model relates to devices for the treatment of domestic wastewater and can be used in the treatment of domestic wastewater of separately located objects of sparsely populated areas and individual residential buildings. When applying the discharge 6 from the septic tank in the air cavity 1, the latter is saturated with oxygen. This contributes to the processing of the discharge by 6 aerobic bacteria, which increases the degree of purification of the drain. Cleaning the drain 6 also contributes to the uniform spraying of it on the surface of the gravel.
