| titleOfInvention | Biological wastewater treatment method |
| abstract | The present invention relates to a method for treating wastewater having a large treatment load such as disposer wastewater. [Solution] Before wastewater including waste disposer treated wastewater is treated at the sewage treatment plant, various other wastewater and disposer wastewater are separately collected and collected in the building or small residential area. Wastewater is treated in the order of pretreatment sedimentation tank, aerobic aeration tank, and anaerobic sedimentation tank. Disposer wastewater is treated with methane fermentation in a separate digestion tank to separate digested sludge and separated water. Combined with the wastewater treatment solution, it is treated and purified through a three-phase coexistence tank and a fish culture tank. The three-phase coexistence tank forms an oxygen concentration gradient from the upper layer to the lower layer, forms the three-phase coexistence conditions of aerobic bacteria, anaerobic bacteria, and facultative aerobic bacteria, and decomposes small molecule organic substances and inorganic salts At the same time, it deodorizes odorous substances such as ammonia and hydrogen sulfide produced by anaerobic bacteria. In the aquaculture tank, nitrates and phosphates are consumed by plant cultivation and fish farming to reduce the processing burden of existing sewage treatment facilities. [Selection figure] None |
