在气水反冲洗V型滤池设置适当的在线检测仪表，采用先进的PLC自动控制系统，通过调节清水阀的开度保证恒水位过滤过程。滤池反冲洗时，采用合适的冲洗方法(单水或气、水反冲)和冲洗强度，既能有效地冲去积泥，又能保存滤料表面一定的生物膜，以保证后期过滤效果。
在氣水反遲洗V型濾池設置適噹的在線檢測儀錶，採用先進的PLC自動控製繫統，通過調節清水閥的開度保證恆水位過濾過程。濾池反遲洗時，採用閤適的遲洗方法(單水或氣、水反遲)和遲洗彊度，既能有效地遲去積泥，又能保存濾料錶麵一定的生物膜，以保證後期過濾效果。

Appropriate online measuring instruments are provided in air-water backwashing V-filters to ensure a constant water level of the filtering process by adjusting the opening of clean water valves using advanced PLC automatic control system. When air-water backwashing process is performed, appropriate washing methods and intensities are employed to wash away the deposition while maintaining certain amount of biofilms on the surface of the filter medium to ensure later filtration effect.
