淀粉基复合絮凝剂的制备及其絮凝效果研究
Preparation and Flocculation Effect of the Starch-based Complex Flocculant
摘要
Abstract
[Objective] The research aimed to discuss the best preparation condition and flocculation effect of starch-based complex flocculant. [Method] Starch, aluminum sulphate and ferrous sulfate as main materials, starch-based complex flocculant was prepared. By using orthogonal design, removal rates of the CODCr and chroma as indicators, influences of the pH, Fe/starch (mass ratio) and Al/starch (mass rati-o) on treatment effect of the dyeing wastewater by complex flocculant were studied. [Result] Considering from removal efficiency of the CODCr, the optimal preparation condition of complex flocculant was that pH was 2.5, Fe/starch ( mass ratio) was 0. 35/1 , and Al/starch (mass ratio) was 1.8/1. Considering from removal efficiency of the chroma, the optimal preparation condition of complex flocculant was that pH was 2. 5 , Fe/starch (mass ratio) was 0. 30/1 , and Al/starch (mass ratio) was 1. 8/1. [ Conclusion] When using the complex flocculant in practical engineering, the optimal preparation condition should be selected according to concreteObjectiveof the removing C0DCr and chroma.关键词
