PAC automatic dosing control method and system applied to sewage treatment process

The invention provides a PAC automatic dosing control method and system applied to a sewage treatment process. The PAC automatic dosing control method comprises the following steps: step 1, inputting data; 2, calculating the treatment capacity of the medicament; step 3, calculating a total dosing flow suggested value; 4, calculating a pump frequency conversion flow coefficient; 5, calculating a frequency suggested value of the dosing pump; and 6, pump frequency output is judged, a dosing pump frequency suggestion value is continuously calculated according to the steps 2-5, and the dosing pump frequency suggestion value is issued to a field PLC substation to conduct frequency control on the dosing pump. According to the PAC automatic dosing control method and system, PAC intelligent regulation and control are realized without considering complex process parameters of a biochemical process section. 本发明提供一种应用于污水处理工艺的PAC自动加药控制方法及系统，包括如下步骤：步骤一、数据输入；步骤二、计算药剂处理能力；步骤三、计算加药总流量建议值；步骤四、计算泵频转流量系数；步骤五、计算加药泵频率建议值；步骤六、判断泵频输
