Wastewater treatment system with minimal mechanical equipment

摘要

The present invention relates to a wastewater treatment device that minimizes mechanical facilities, decomposing organic matter, and pumping sedimented sludge through a submersible pump installed in the settling tank to an anaerobic tank equipped to enable release of phosphorus from the inside of microorganism cells, phosphorus absorption By pumping the wastewater in which phosphorus has been absorbed by the compressed air supplied from the compressed air supply unit to the anaerobic tank to the anaerobic tank provided so as to be able to do so, to the anaerobic tank and the anaerobic tank, the agitator is excluded while stirring, so that the wastewater can be treated. can be minimized, so that power consumption can be reduced as well as maintenance due to the minimization of mechanical equipment.
