- 摘要:
- 污水处理厂的高效沉淀池由于设计构造和水力条件特殊,其池面及斜管周边均易滋生大量藻类,不仅会堵塞斜管、降低沉淀效率、增加运行成本,还会导致某些出水指标不达标。为解决此类问题及改善沉淀效果,设计和开发了“光伏+反洗”复合工艺技术。通过优化分布式光伏板的光照角度、架设方式等,最大程度避免阳光直射高效沉淀池的池面,有效抑制了池内藻类的繁殖;此外,配套构建气源、调节阀、自控系统等一体化反冲洗系统,形成了一套操作简便、运行高效、效果可控、成本较低的反洗方案,可将残存在斜管上的附着藻类彻底清除。自“光伏+反洗”复合工艺系统实施以来,高效沉淀池池面及斜管周边藻类附着基本消失,且该区域光伏系统发电量达57.3×104 kW·h/a,总体上降低了运行成本。
- Abstract:
- Due to the special design structure and hydraulic conditions, a large number of algae are prone to grow on the surface of the high-efficiency sedimentation tank and the surrounding inclined tubes, which will not only block the inclined tube, reduce the sedimentation efficiency, and increase the operating cost, but also cause some effluent indicators to fail to meet the standards. In order to solve such problems and improve the sedimentation effect, the photovoltaic and backwash composite process has been designed and developed. By optimizing the illumination angle and erection mode of the distributed photovoltaic panels, direct sunlight is avoided on the surface of the high-efficiency sedimentation tank to the greatest extent, which effectively inhibits the growth of algae in the pool. In addition, the integrated backwash system such as air source, regulating valve, and automatic control system is constructed to form a backwashing scheme with simple operation, high efficiency, controllable effect and low cost, which can completely remove the attached algae remaining on the inclined pipe. Since the implementation of the photovoltaic and backwash composite process system, the algae adhesion on the surface of the high-efficiency sedimentation tank and the surrounding inclined tubes has basically disappeared, and the annual power generation of the photovoltaic system in this area has reached 573 000 kW·h, which has generally reduced operating costs.
