摘要
针对采选矿废水处理中,通常采用的以进出水COD值作为药剂投加控制依据的时间滞后性问题,引入反应过程的ORP值作为辅助控制参数,研究发现,反应系统ORP值与出水COD值呈现近似相关性,ORP值越高,出水COD值越低。工业生产中,设置ORP值≥300 mV,可以保证出水COD值稳定低于60 mg/L,实现了废水处理的全过程控制。
The research adopt ORP in reaction process act as auxiliary control parameter in order to make up the time lag that agent dosage usually according to COD of water inlet and outlet in mining wastewater treatment. ORP in reaction process and COD of water outlet are approximate related that higher ORP corresponding lower COD according to the basic experiment. Keeping ORP value bigger than 300 mV can guarantee COD of water outlet lesser than 60 mg/L and achieve whole process control in wastewater treatment.
