Abstract:
The capability of im idac loprid w astew ater trea tm en t by com b ined Anne robicH ydro lysis-pressurized b io log ical ox idation pro cess w as studied in th is paper. The stud ies show ed that the hydro lys is e ffect was im proved due to co-m etabo lism by m ix ing pesticide w astewa ter and Sew age in term of a vo lum e ratio as 8B2. The feasib le runn ing param eter o f pressur ized bio log ica l ox ida tion process w as that the pressure am ounted to 01 3MPa, DO w as in scope o f 5 and 6m g /L, and theHRT w as 416 h. The effect of pestic idew astew ater treatment w ou ld not be im pac ted obv iously by the h igh sa lt content. The vo lum e load of pressurized b io log ical ox idation process should be contro lled in a low leve lwhen the effluent COD v alue w as requ ired to be low, as shou ld be contro lled in a high leve l when dea ling effic iency o f the reactor w as requ ired to be h igh.
