<p>The present invention relates to a wastewater treatment system. Organic food waste and human waste are separated from each other by using a solid-liquid separator before discharge to a terminal sewage disposal plant. The precipitated sludge and solid are compressed, dehydrated, turned into cake, packaged in a sealed container, sent to a compost plant, and matured to be used as compost resources. The supernatant of the wastewater from a residential site from which organic matter is removed by at least 60% is sent to the terminal sewage disposal plant so that the wastewater treatment facilities can be simplified and the treatment cost can be reduced. With food waste pulverization and disposal through toilets and drains in residential sites allowed by law, an increasing number of households are pulverizing and discharging food waste. As a result, slime accumulation leading to sewage pipe clogging and overflow damaging low-level houses are becoming more and more frequent. Water collection tank solid separation collection and cake packaging and discharge for dealing with the problem are effective in terms of food waste desalination, solid composting, resource recycling while reducing the organic matter treatment load of a terminal sewage disposal plant and reducing wastewater logistics cost.</p> |
