The application discloses a sewage treatment plant carbon source adding amount control method, device, equipment and medium, relates to the sewage treatment automatic control technical field, and carries out pretreatment to the multi-source control data of the sewage treatment process; the nitrogen index emission load and the water yield of the current control period are updated rolling, the cumulative nitrogen index emission load and the cumulative water yield between the starting control period and the current control period are obtained; based on the cumulative nitrogen index emission load, the cumulative water yield, the residual water yield prediction value between the next control period and the end control period of the current control period, the dynamic control set value is determined; the target carbon source adding amount is determined by using the water nitrogen index concentration and the dynamic control set value, the target carbon source adding amount is converted into a control instruction and is issued to an executing mechanism, so that the executing mechanism controls the carbon source adding amount, solves the problem that it is difficult to consider the constraints and dynamically adjusts according to the cumulative emission margin, and realizes the automatic control of the carbon source adding amount.

The present application relates to rectification technical field, particularly to a kind of rectification tower system balance full-automatic separation control method, rectification tower system includes rectification I tower, control method includes to rectification I tower is carried out material balance control and gas-liquid equilibrium control, gas-liquid equilibrium control is used to control the amount of backflow of material backflow to rectification I tower;The material balance control includes: detecting the actual feed flow of rectification I tower and the actual liquid level value of the first reflux tank corresponding to rectification I tower, in combination with the overhead take-off component set point of rectification I tower and the overhead take-off component density, the overhead take-off material flow of rectification I tower is calculated and controlled in real time.By the method, the stability and efficiency of rectification tower system are improved, and the energy consumption cost and the volatility problem of product are reduced.
