Futian Sewage Treatment Plant is located in the downtown area of Futian District, nearby the north side of Shenzhen Mangrove Forest Nature Reserve. The service area covers 62.43 km2. Long-term control scale is 800,000 m3 / d, and the construction scale of first phase is 400,000 m3 / d. It was completed in 2015. The first phase of the project adopts double-covered semi-underground structure, and the initial settling tank, biological pool, the top of secondary sedimentation tank are double-decked to build a public park, with an area of about 80,000 m2.
1. 国内大规模污水厂中首次运用双层覆盖半地下式立体式布局，节约土地资源.
1. The three-dimensional layout characterized with double-covered, semi- underground structure is first used in domestic large-scale sewage plants, greatly saving land resources.
2.既有全地下式污水厂的优美环境，操作管理又具有地上式污水厂的便捷。
2.It has both the beautiful environment of the underground sewage plants and the convenient operation and management of the ground type sewage treatment plants.
3多段强化脱氮A2/O主体工艺先进可靠。具有很强脱氮除磷效果和抗冲击负荷的能力。
3. Multi-stage enhanced denitrification A2 / O is advanced and reliable. The utility model has the advantages of strong nitrogen and phosphorus removal effect and shock load resistance.
4.节能显著。采用精确曝气控制系统较传统曝气系统节能8%~10%。缺氧段采用低速大叶轮水下推进器电耗为传统潜水搅拌器的30%。
4. Energy saving. Accurate aeration control system is adopted, saving 8%~10% energy than traditional aeration system. In the anoxic stage, the power of the low speed large blade underwater propeller is 30% of that of the traditional diving mixer.
5.污水厂实行全流程密封加盖除臭，确保污水厂周边区域及顶部公园良好的空气质量。
5. Sealing, capping and deodorizing are adopted during the whole process, so as to ensure the good air quality in the surrounding area and the above park.
