【摘要】：根据水厂出厂水浊度和翻板滤池出水浊度内控指标的区间要求,建立回归分析方程,做出拟合直线,通过回溯法确定了高效澄清池出水浊度区间,并探索出PAC、PAM投加量及污泥回流比的优化区间。生产性试验表明,根据滤后水浊度内控指标为0.5~0.9 NTU,反馈控制高效澄清池出水浊度区间为1.8~3.1 NTU,探索出PAC投加量为14~22 mg/L、PAM投加量为0.08~0.16 mg/L、污泥回流比为2%~6%的最优药剂组合,从而指导水厂科学生产,达到了优质供水、节能降耗的目的。
[Abstract]:According to the requirements of the internal control index of turbidities and turbidities in the effluent of the water plant, the regression equation was established, the straight line was fitted, and the turbidity interval of the high efficiency clarifier was determined by the backtracking method. The optimization interval of PAM dosage and sludge reflux ratio was explored. According to the internal control index of the turbidity of filtered water is 0.5 ~ 0.9 NTU, and the feedback control of the turbidity interval of the high efficiency clarifier is 1.88 ~ 3.1 NTU, it is found that the optimal combination of chemicals with PAC dosage of 148mg / L and sludge reflux ratio of 0.16 mg / L and sludge reflux ratio of 2% can be used to guide the scientific production of water plant. To achieve the goal of high quality water supply, energy saving and consumption reduction.
