- Abstract:
- In response to the shortcomings of high cost, high energy consumption and inconvenient operations management of underground sewage treatment plants, Dalinghe Sanhua water purification plant in Guangzhou has adopted some innovative measures, including combining with river embankments and cleverly selecting locations to solve the problem of difficult landing, making full use of the embankment elevation to reduce the buried depth of the underground tank by approximately 3.60 m, dividing the underground tank into 4 fire zones in combination with the process layout, enhancing the use of natural light to decrease the lighting energy consumption by approximately 4 088 kW·h/year, the air blower being doubled as ventilation of the underground space to save energy consumption of approximately 60 501 kW·h/year, and arranging the membrane tank close to the pretreatment area and sludge treatment area to facilitate the operational convenience and management. Overall, this project provides an engineering case reference for “double reduction and one increase” (i.e. reducing investment and energy consumption, increasing efficiency) of domestic underground sewage treatment plants.
