| 英文摘要 | This plant-scale investigation compared two process improvement strategies for Lianyungang drinking water treatment plant (L-DWTP), a typical plant employing conventional processes to treat source water impacted by seasonal non-point pollution. Hierarchical cluster analysis grouped it into two clusters, i.e. normal period and polluted period. Originally, the L-DWTP exhibited poor organic matter removal efficiency, and 76.7% of the effluent permanganate index (CODMn) levels exceeded the state regulation requirement (<3mg/L). In addition, chloroform concentration was observed to exceed the regulation requirement (60 mu g/L) by 14.2 and 56.2% in normal and polluted periods. The combined use of FeCl3 and KMnO4 (Fe-Mn enhanced coagulation) increased the CODMn removal efficiency by 10.6%, and decreased the chloroform formation by 26.4%. It indicates that about 94.5% of effluent CODMn values and nearly all of chloroform levels may meet the standard in normal period. However, Fe-Mn enhanced coagulation shows limitation in polluted period. The advanced treatment by ozone-biological activated carbon process (O-3-BAC) increases the CODMn removal efficiency by 29.5%, and decreases the chloroform formation by 43%, indicating that effluent levels may meet the standard both in normal and polluted periods. Cost was also compared, and the extra cost for Fe-Mn enhanced coagulation is only about 20% of that for O-3-BAC. In conclusion, O-3-BAC works well both in normal and polluted periods. Fe-Mn enhanced coagulation only shows good performance in normal period, but is more economical. Therefore, it is proposed to use Fe-Mn enhanced coagulation in normal period, while O-3-BAC during polluted period. These obtained plant-scale data are valuable to optimize the operation of DWTPs with similar challenges. |
