Abstract:
The overall purpose of this research is to examine the impact of untreated sedimentation tank sludge water (USTSW) recycle on water quality during treatment of low turbidity water in coagulation—sedimentation processes. 950 mL of raw water and different concentrations of 50 mL USTSW are injected into six 1 000 mL beakers without coagulant.The results indicate that USTSW characterized as accumulated suspended solids and organic matter has active ingredients, which possess the equivalent function of coagulant. The optimal blended water turbidity is in the range of 10-20 NTU, within which USTSW recycle achieves the highest save coagulant rate. The mechanism of strengthening coagulation effect when USTSW recycle mainly depends on the chemical effect and physical effect. What is more, through scanning electron microscopy (SEM), it is found that the floc structures with USTSW recycle are more compact than those without USTSW recycle. Besides, the water quality parameters of color, NH3-N, CODMn, UV254, total aluminum, total manganese when USTSW recycle is better than the raw water without recycle, indicating that USTSW recycle can improve water quality with strengthening coagulation effect.
Key words: untreated sedimentation tank sludge water recycle low turbidity optimal blended water turbidity water quality
