A method for treating high-concentration organic wastewater is provided to treat the high-concentration wastewater for a short time, and produce organic manure needed for organic farming. Large-sized adulterations are filtered off from high-concentration wastewater and sludge containing fine suspended solids is separated the from high-concentration wastewater through a pretreatment process(S100). The wastewater passed by the pretreatment process is purified to form liquefied fertilizer through a liquefied fertilizer process(S200). The sludge discharged from the pretreatment process and the sludge discharged from the liquefied fertilizer process are deodorized to form manure through a manure process(S300). The wastewater discharged from the pretreatment process is completely purified and discharged, and a thickened liquid generated during purifying of the wastewater is transferred to the liquefied fertilizer process, through a biological treatment process(S400). |
