Mechanisms to clean sewage

Sewage drained from homes passes through sewer pipes (gesuikan) and enters the sand basin.
In this pond, remove the large garbage and sand in the sewage, remove it, and pump it up with a sewage pump. First, send it to sedimentation pond.

Slowly drain the sewage (gesui) and sink the fine garbage that could not be removed in the sand basin (chinsachi), and remove it. I will remove it.
The sinking mud is collected by a sludge scraping machine and sent to the adjusted sludge tank.

The mud with small creatures (seibutsu) (microorganisms (biseibutsu)) that cannot be seen in the eyes (me) is called activated sludge.
The activated sludge (Kasei Odei) and the water (mizu) that first came out of the sedimentation pond (Saishochindenchi) are blown in with a sprayer (Sankisochi) and stir while watching.
The sewage is polluted by small creatures (seibutsu) and the water is clean.

Since the water (water) that has passed out of the reaction tank contains activated sludge, it takes time to slow down the mud (doro) in this pond. Sink in.
The water (mizu) in the upper part (ho) overflows from the triangular (Sankaku) cough on the surface of the pond (ike) and flows into the contact tank. ) To do.
The sinking mud is returned to the reaction tank, and the excess mud is sent to the adjustment sludge tank. )

The clean water (mizu) is disinfected with hypochlorite (Jiaenso-san) sodium solution (Yoeki), and flows to Tsurumi River (Tsurumigawa).

The excess mud of the first sedimentation pond and the final sedimentation pond is submerged further and darkened.
The dark mud is sent to the northern sludge resource (Hokubu Odekagen) conversion center and processed.

At the Water Reclamation Center, we check every day to see if water is clean.
In addition, a microscope (kenbikikyo) also confirms the state of microorganisms (biseibutsu) of activated sludge.

At the Tsuzuki Water Reclamation Center, you can receive a request for a facility tour from time to time. For more information, please see here (link to the tour guide page).
