光伏电站水消防和生活污水处理方案的优化设计
|
摘要
文章根据光伏电站火灾危险性等级,通过控制单栋建筑物规模,实现取消水消防,并根据不同构筑物的火灾类别有针对性地采取相应的消防措施。许多光伏电站建设了地埋式一体化生活污水处理装置,但实际运行效果不理想。建议在干旱地区采用沉淀池和蒸发池,并考虑低温或阴雨季的调蓄容积;非干旱地区采用包括厌氧—兼氧—好氧工艺的生物塘处理工艺,可以利用当地的土石类建筑材料和当地优势种群的水生物处理污水。这样的设计方案具有建设和运行费用低、审批简单、实际运行效果好的优点,适于在光伏电站中推广使用。
Based on the fire risk level in photovoltaic(PV)power stations, this paper proposes to take corresponding measures for fire protection according to the fire categories of different structures by controlling the scale of a single building while abandoning water fire protection. Some PV power stations has constructed underground integrated sewage treatment equipment, but the actual effect is not satisfactory. Therefore, the paper suggests that in the arid area, sedimentation or evaporation tanks should be used and the storage volume in low temperature or rainy seasons should be considered as well; while in the non-arid area, biological ponds with treatment process of anaerobic-facultative-aerobic technology are preferable, making use of local building materials like earth and rock, and the aquatic organisms of the dominant population as well. Such designs have the advantages of low cost of construction and operation, simple approval, and good running effect, which are suitable for widespread application in PV power stations
