The new environmentally friendly harmless plastic septic tank is mainly composed of three parts

1. The sedimentation corruption zone, its main function role is to precipitate domestic sewage to remove the coarse substances that can be precipitated in the wastewater. At the same time, the wastewater undergoes septic function here, so that a part of the difficult-to-decompose organic matter with complex structure is degraded into easy Decomposed substance

2. The partition is mainly used to convert the water in the pool direct water to circulating water, which increases the residence time of the sewage in the pond, makes the sewage in the pond contact with the sedimentation sludge for longer time to degrade produce more Microorganisms decompose swallow sewage.

3. The filter treatment area, whose function is to further treat sewage in this area. Converting COD in sewage into harmless inorganic substances is a key component of the equipment.
