influent flow

Study of influent flow distribution methods and strategies in step-feed A/ O process

分段进水A/O工艺流量分配方法与策略研究

Under decided process parameters and influent water quality conditions, the objective function is based on the least errors of wastewater quality. The optimized parameter for influent flow distribution ratios are ( 37.2)%,( 27.4)%, 23.2% and 12.2% respectively.

在确定的工艺参数和进水水质条件下，以出水水质模拟值与控制出水水质间的最小误差为目标函数，得到各级进水流量分配比分别为37.2%、27.4%、23.2%和12.2%。

The average flow rates in rainy and dry seasons were 417.1 and 206.8m3/d. The sum of the infiltration and the evapotranspiration loss in period without rain occupied 42.1%~ 60.5% of the influent water.

监测结果表明，雨季、旱季平均流量分别为417.1206.8m3/d，无降雨期间渗漏、蒸发蒸腾损失的水量之和占进水的42.1%~60.5%。

The influence factors, including stirring time, stirring pH value, influent flow rate, pH value, temperature, the dosage of NaCl, current intensity and electrolysis time were investigated respectively through the single factor experiments.

采用单因素实验考查了碱洗搅拌时间、碱洗pH值、电解时间、进水pH值、电流强度、进水流量、水温、氯化钠投加量等因素对活性炭再生效果的影响。

The influent flow rate was steadily decreased while keeping the time intervals constant between successive increments.

为保持相继增加之间的时间间隔不变，流入的流速会持续降低。

In order to improve effluent water quality prediction precision of wastewater treatment system, the main factors which have influence on the effluent quality are analyzed according to the process flow and the characteristics of influent water quantity of a wastewater treatment plant.
