摘要

在脱水过程中产生精矿，并将其返回到工艺系统的起点。所得浓缩物的质量，以及污染物返回负荷的大小，影响着废水生物处理过程中的电力需求。以下研究介绍了位于波兰的五个污水处理厂的集中质量检测结果。测定了悬浮物含量与浓缩液中氨、COD浓度的关系。据估计，总体悬浮固体的增加导致COD增加约1.15 kgCOD/kgTSS。TSS浓度与氨无相关性。据计算，完全消除污泥中的悬浮固体将使所有五个物体的用电量减少约535兆瓦时/年。

Influence of Effluent Quality from Sludge Dewatering on Electricity Consumption

Abstract During the dewatering process, centrate is produced, which is returned to the beginning of the technological system. The quality of the resulting centrate, and therefore the size of the returned load of pollutants, affects the demand for electricity in the process of biological wastewater treatment. The following study presents the results of centrate quality tests at five wastewater treatment plants located in Poland. The dependence between suspended solids content and ammonia and COD concentrations in the centrate was determined. It was estimated that an increase in the overall suspended solids leads to an increase in COD by about 1.15 kgCOD/kgTSS. No correlation was found between TSS concentration and ammonia. It was calculated that the complete elimination of suspended solids from the sludge would reduce the electricity consumption for all five objects by about 535 MWh/y.
