提高重力式无阀滤池反冲洗效果的措施

Measure to Improve Backwashing Effect of Gravity Valveless Filter

重力式无阀滤池具有产水水量大、操作简单等特点,应用广泛。为提高反冲洗效果,采用诱导强制反冲洗措施,设计诱导强制反冲洗装置,利用泵抽真空方式,定时形成压强差,强制虹吸,实现定时反冲洗,由此保证出水水质和水量。对重力式无阀滤池的工作原理、设计选型进行了介绍,并分析了提高反冲洗效果措施的应用。

The gravity valveless filter has the characteristics of large water production and simple operation,and is widely used.In order to improve the backwashing effect,the induced forced backwashing measure was adopted,and the induced forced backwashing device was designed,and the pump vacuum mode was used to form a pressure difference at regular interval,and the forced siphon was used to realize the regular backwashing,so as to ensure the quality and quantity of effluent.The working principle,type selection design of gravity valveless filter were introduced,and the application of measure to improve the backwashing effect was analyzed.
