- Abstract:
- With the gradual improvement of water purification plant diacharge standards, there is a growing demand for stability, low carbon emissions, and energy efficiency in the construction and operation of such facilities. Accurate oxygen supply has become a standard feature in the construction of water purification plants. In order to fully utilize its function, it is essential to assess the changes in water quantity and quality of water purification plants, and implement appropriate oxygen supply equipment configurations. A water purification plant is designed with an underground layout, and the primary effluent indexes need to comply with the quasi-Ⅲ class limits specified in Environmental Quality Standards for Surface Water (GB 3838-2002). The biological reaction tank is equipped with blast aeration and oxygen-enriched aeration. The two sets of aeration equipment were adjusted in tandem to achieve accurate oxygen supply. Through optimization, the configuration of the oxygen generator was adjusted from 3 sets with aeration intensity of 170 m3/h to 2 sets with aeration intensity of 80 m3/h plus 1 set with aeration intensity of 160 m3/h in the near future, and eventually to 3 sets with aeration intensity of 160 m3/h in future. After carefully selecting the blower, it was essential to establish a continuous connection of the air volume within the range of operating conditions. It highlighted the importance of pre-estimation in ensuring smooth and efficient operation.
