采用适合其分散处置特点的流化床和臭氧气浮装置对高档社区的景观水以及建筑中水进行再生处理。首先针对流化床工艺,用Fe3O4作为回流絮凝助凝剂,以增强悬浮层的稳定形成。其次,增设微孔曝气系统。一方面对流化床回流的Fe3O4进行水力再生;另一方面提高水中的溶解氧,降低臭味,提高系统的好氧微生物处理能力。最后,改变工艺流程,使景观水进水杂排水池,通过流化床处理。运行结果表明,出水水质完全符合GB/T18920-2002和GB/T18921-2002中的娱乐性景观环境用水、道路清扫、城市绿化和车辆冲洗的用水水质标准。
Fluidized beds and ozonated flotation devices suitable for their decentralized disposal are used to regenerate landscape waters in high-end communities and water in buildings. First of all, for the fluidized bed process, with Fe3O4 flocculation coagulant as reflux to enhance the stability of the suspended layer formation. Second, the addition of microporous aeration system. On the one hand, the fluidized bed reflux Fe3O4 for hydraulic regeneration; on the other hand improve the dissolved oxygen in water to reduce the odor and improve the system of aerobic microbial processing capacity. Finally, change the process, so that landscape water into the water drainage pool, through the fluidized bed treatment. Operation results show that the water quality in full compliance with GB / T18920-2002 and GB / T18921-2002 recreational landscape water environment, road cleaning, urban greening and vehicle flushing water quality standards.
