Structural diagram of the integrated fecal and sewage septic tank

Structural diagram of the three-compartment septic tank

Structural description

In the first compartment, a mesh partition and cosmic packing are placed. The packing is φ60mm, with a surface area 5 to 6 times larger than that of conventional spherical packing. It is all made of PP and has a service life of more than 40 years. The packing accounts for 30% of the effective volume in this area.

In the second compartment, annular bundled packing is evenly fixed by a special packing support, which is integrally injection molded. The packing support maintains a service life of over 40 years, and the packing accounts for 30% of the effective volume in this area.

In the third compartment, mesh partitions and spherical packing are placed, with the packing accounting for 30% of the effective volume of this area.

Three-compartment fecal treatment facilities are generally used in conjunction with water-flush toilets and consist of parts such as the fecal inlet pipe, the partition tank, the fecal passage pipe, and the cover plate.

Structure and function

The structure and function of the first tank in a three-compartment septic tank

Function: Every day, it accepts fresh feces and undergoes anaerobic fermentation to decompose and stratify: the upper layer of fecal skin, the middle layer of fecal liquid, and the bottom layer of fecal residue, which retain and settle parasite eggs.

Conditions: Tight sealing, relatively still or slow-flowing inside the pool, and an appropriate hydraulic retention time.

The structure and function of the second tank in a three-compartment septic tank

Function: To continue the retention and sedimentation of parasite eggs in the tank, achieve deep anaerobic fermentation, increase the concentration of free ammonia, and kill bacteria and eggs.

Condition: It should be tightly sealed to prevent fecal lumps, fecal skins and fecal residues from flowing into the second pool.

The structure and function of the third tank in a three-compartment septic tank

The fecal liquid flowing into the third pool is usually well-rotted. The bacteria and insects in it have been basically killed and removed, and it can be used for fertilization.

The main function of the third pool is to store manure. The volume of the third pool is basically determined by the frequency of fertilization

It is determined by the amount of fertilizer applied each time.

If the fecal water from the third pool is not used as fertilizer but is directly discharged for shallow soil filtration purification treatment,

The volume of the third pool can be appropriately reduced.
