矿区自来水厂多参数控制系统

Multi-parameter Controlled Raw Water Treatment Technology For Mine Waterworks

以某矿区自来水水厂在处理矿井尾水中出现的特殊问题为例,介绍了采用流动电流、浊度、流量、压力、液位等相关参数构成的流动电流与浊度双闭环控制、外加流量前馈控制,并辅以对原水的混合、稳流和助凝剂投加等辅助措施的多参数控制方法在矿井尾水水处理系统中的应用。

Taking the special problems occurred during the treatment process of mine tailwater in a waterworks serving mining area as an example this paper explains the application of multi - parameter controlled method in mine tailwater treatment system, which is consisted of dual dosed loop control of stream current and turbidity and flow feed forward control adopting parameters concerned of stream current, turbidity, flow, pressure and liquid level while assisted by other auxiliary measures of raw water mixing, overflow control and PAM dosing and etc.
