- Abstract:
- Underground reclaimed water plant has the advantages of small footprint area, environmental friendliness and high resource utilization rate, thus has attracted wide attention at home and abroad in recent years, and has become one of the important choices for the construction of urban sewage treatment facilities. The treatment processes, key units, equipment and treatment performances between two typical underground reclaimed water plants, the Guiyang Qicaihu plant and Denmark Hiller-d plant, were compared. The two plants both showed significant land saving performance compared with the conventional wastewater treatment plants. The two plants were relatively complete in terms of sewage treatment line, sludge treatment line and odor treatment line, which reflected the characteristics of high standards. Under different national policies, the effluent quality of the two plants was generally good, and the TN in effluent from Hiller-d plant was as low as 1.96 mg/L. On the whole, the two underground plants showed better comprehensive benefits. On this basis, three inspirations for the high quality development of underground reclaimed water plant were further discussed.
