隨著社會(huì)的進(jìn)步和經(jīng)濟(jì)的發(fā)展，加之日益嚴(yán)峻的水資源需求，人們對城市污水處理的要求愈加嚴(yán)格。 the total hydraulic retention time is less than other craft. Running alternately by the anaerobic, anoxic anaerobicaerobic conditions can inhibiting filamentous bacteria breeding, overe the sludge bulking, and the SVI generally less than 100, it is advantageous to the treatment of sewage and sludge after separation, in anaerobic and lack of oxygen in the operation of the segment only gentle stirring, low operating cost. The process effect of sewage treatment is well, and can save money for th
