A plant for wastewater treatment is provided by an exemplary embodiment of the present invention. The plant for wastewater treatment includes a reactor into which wastewater and air flow into and depart from; multi-layer sludge separating portions, wherein pollutants in wastewater can be decomposed by increasing an amount of dissolved oxygen because upward moving time of intruded wastewater and air bubbles can be increased by including a reactor divided into upper and lower sides, and fluidity of wastewater may be improved by forming a residential space; and carriers located between the sludge separating portions and including a large amount of microbes, wherein wastewater treatment is performed by a biological reaction caused by contact between the carriers and wastewater.

Plant for wastewater treatment

An apparatus and method for treating wastewater are provided. The method for treating wastewater includes: a pre-treatment step of removing impurities contained in high concentration wastewater and crushing the impurities using a crusher; a first aerobic treatment step of supplying wastewater containing organic acids to a first aerobic tank and injecting air to the first aerobic tank to be aerobically treated; an anaerobic treatment step of supplying the wastewater, from which excess organic acids are removed by the aerobic treatment, to an anaerobic tank to be anaerobically treated; a degassing step of supplying the wastewater treated in the aerobic and anaerobic treatment steps to a degassing tank to remove air and gas; and a post-treatment step of precipitating the wastewater aerobically treated using a solid-liquid separation tank, a pressure floatation tank or a precipitation tank.
