摘要

本文提出了用硫酸铝(Al2(SO4)3)和氯化铁(FeCl3)两种混凝剂对实际乳业废水进行混凝和脱馏预处理的方法。为了优化最佳混凝条件，使COD和浊度去除率达到最大值，采用了响应面法(RSM)。方差分析表明，降低浊度和COD的相关系数(R2)分别为0.959和0.840，说明二次开发模型的有效性及其预测质量。在Al2(SO4)3浓度为1200mg/L、处理时间为38.57min的条件下，模型预测浊度和COD去除率分别为98.18%和77.06%。这些结果与实验结果一致。

OPTIMIZATION OF COAGULATION PRETREATMENT OF A REAL DAIRY EFFLUENT USING A RESPONSE SURFACE METHOD

This paper proposes a pretreatment of a real dairy effluent by coagulation and decantation using two types of coagulants, aluminum sulfate (Al2(SO4)3) and ferric chloride (FeCl3). In order to optimize the best coagulation conditions leading to maximums of COD and turbidity removals, response surface method (RSM) was employed. The analysis of variance showed that the values of the correlation coefficients (R2) for the reduction of turbidity and COD were found equal respectively to 0.959 and 0.840, which gives an idea about the validity of the quadratic developed models and their predictive qualities. The results predicted by the models were 98.18 and 77.06% of turbidity and COD removals, at Al2(SO4)3 concentration of 1200mg/L and time of treatment of 38.57min. These results are in agreement with those obtained experimentally.

期刊介绍： Journal of Urban and Environmental Engineering (JUEE) provides a forum for original papers and for the exchange of information and views on significant developments in urban and environmental engineering worldwide. The scope of the journal includes: (a) Water Resources and Waste Management [...] (b) Constructions and Environment[...] (c) Urban Design[...] (d) Transportation Engineering[...] The Editors welcome original papers, scientific notes and discussions, in English, in those and related topics. All papers submitted to the Journal are peer reviewed by an international panel of Associate Editors and other experts. Authors are encouraged to suggest potential referees with their submission. Authors will have to confirm that the work, or any part of it, has not been published before and is not presently being considered for publication elsewhere.
