反硝化深床滤池自控问题分析及对策

Analysis and countermeasures of automatic control of denitrification deep bed filter

反硝化深床滤池一般采用恒水位运行控制方式,但是在传统控制逻辑下,遇到系统受到冲击的情况,无法及时自行处理,需要耗费大量人力进行干预,防止系统瘫痪,从而影响出水水质,存在一定的运行隐患。通过对滤池的自动化控制程序进行优化,在恒水位运行的前提下,由阀门开度来控制反冲洗和氮气释放,大大增加了滤池的运行效能和安全性能,避免了不必要的人力投入。

The denitrification deep-bed filter generally adopts constant water level operation control mode,but under the traditional control logic,when the system is impacted,it cannot handle it in time and requires a lot of manpower to intervene to prevent the system from paralyzing,which affects the water output.There are certain hidden dangers in water quality.By optimizing the automatic control program of the filter,under the premise of constant water level operation,the valve opening is used to control the backwash and nitrogen release,which greatly increases the operating efficiency and safety performance of the filter,and avoids unnecessary manpower input.
