Optimization of organic-containing wastewater and sludge treatment systems

Abstract

An enzymatic-cavitation method for the biological treatment of organic-containing wastewater and sludge treatment has been developed, according to which the air supply is carried out not by compressors, but rather ejectors. In addition, low-intensity cavitation is provided. The biological treatment of the wastewater has been performed at a temperature of 10–42°C. The energy consumption of the process is reduced by six times, while the time of sludge treatment is 8–10 h at a pressure of 0.30–0.35 MPa. The treated sludge has some adsorptive properties.
