Discussion on Characteristics of TOC of Sewage Treatment Plant in Guilin
The total organic carbon(TOC)was monitored from three sewage treatment plants and the receiving waterbody in guilin to analyze the TOC variation with water yield and the time.Meanwhile,chemical oxygen demand(COD) from three sewage treatment plants was monitored.The linear regression of COD and TOC was obtained with the least square method and the correlation test was carried out.The results indicate that the concentration of TOC in Qilidian sewage treatment plant is the highest in three sewage treatment plants and has the best treatment effect;the concentration of TOC in high water yield are higher than low water yield;there is a significant linear correlation between COD and TOC values of these samples except Beichong sewage treatment plant.
