摘要

摘要本研究采用统计设计实验，通过二水平、五因素全因子设计(FFD)和人工神经网络(ANN)，探讨混凝-絮凝过程的参数优化。采用混凝剂投加量、快混、慢混、沉降时间和种子种类进行试验设计。浊度去除、pH值和电导率变化被用作响应/输出。用脱壳(DSCP)和去壳(USCP)辣木籽饼粉对大坝饮用水处理效果进行了试验研究。两种方法对浊度去除的建模精度都很高，FFD和ANN的决定系数()分别为0.90和0.96。验证试验也证明了该模型具有良好的效率，去除率为90.42%，与FFD模型(90.71%)和ANN模型(92.33%)的去除率非常接近。因此，MO种子饼粉可以作为广泛使用的化学品的替代品。

Optimization of coagulation-flocculation process with dehulled and unhulled Moringa oleifera cake powder by 25 full factorial design and artificial neural networks: effect on dam water quality

ABSTRACT This study explores parametric optimization of coagulation-flocculation process using statistically designed experimentation via two-level, five factors full factorial design (FFD) and artificial neural network (ANN). The experimental design was produced using Coagulant dosage ), Fast mixing ), Slow mixing ), Settling time and Seeds kind . Turbidity removal, pH and conductivity variations have been adopted as responses/outputs. The efficiency of Moringa oleifera Lam (MO) seeds cake powder was tested using dehulled (DSCP) and unhulled (USCP) seeds on dam water treated for drinking purposes. Both methods modelled Turbidity removal with high accuracy with a coefficient of determination ( ) of 0.90 and 0.96 for FFD and ANN, respectively. Validation tests also proved to have good efficiency, with a removal rate of 90.42%, which is very close to that obtained by FFD (90.71%) and ANN (92.33%) models. Thus, MO seeds cake powder could serve as a replacement for the chemicals widely used.

期刊介绍： Urban Water Journal provides a forum for the research and professional communities dealing with water systems in the urban environment, directly contributing to the furtherance of sustainable development. Particular emphasis is placed on the analysis of interrelationships and interactions between the individual water systems, urban water bodies and the wider environment. The Journal encourages the adoption of an integrated approach, and system''s thinking to solve the numerous problems associated with sustainable urban water management. Urban Water Journal focuses on the water-related infrastructure in the city: namely potable water supply, treatment and distribution; wastewater collection, treatment and management, and environmental return; storm drainage and urban flood management. Specific topics of interest include: network design, optimisation, management, operation and rehabilitation; novel treatment processes for water and wastewater, resource recovery, treatment plant design and optimisation as well as treatment plants as part of the integrated urban water system; demand management and water efficiency, water recycling and source control; stormwater management, urban flood risk quantification and management; monitoring, utilisation and management of urban water bodies including groundwater; water-sensitive planning and design (including analysis of interactions of the urban water cycle with city planning and green infrastructure); resilience of the urban water system, long term scenarios to manage uncertainty, system stress testing; data needs, smart metering and sensors, advanced data analytics for knowledge discovery, quantification and management of uncertainty, smart technologies for urban water systems; decision-support and informatic tools;...
