- Abstract:
- The A/O+diatomite process was optimal designed, and used in Liangwu wastewater treatment plant with capacity as 1 000 m3/d in Lichuan City, Hubei Province. The hydraulic process, the retention time of biological treatment tank, the reflux of mixed liquid and sludge, the mixing mode of diatom fine soil and the way of disinfection were optimized. When HRT of regulating tank and AO tank was respectively 6 h and 9.5 h (anoxic 2.5 h, aerobic 7 h), the diatomite was mixed via mechanical stirring, and ultraviolet radiation disinfection was replaced by chlorine dioxide disinfection, the removal efficiency of SS, NH3-N, TP, animal and vegetable oil and Fecal Coliform were more than 90%. After operation for 4 months, the effluent reached the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).
