| 摘 要： | 通过调整复合混凝剂优化处理工艺处理凉果废水,研究凉果废水的处理效果。通过数据分析可以得出结论:采用聚合硫酸铁、聚铝复合混凝剂,其适宜的用量为300 mg/L。凉果废水经过复合混凝处理,其糖及盐分去除率分别高达98.3%、99.7%,COD去除率和脱色率去除率分别为99.6%、96.9%,均达到《污水综合排放标准》(GB8978-1996)的一级标准。

| Abstract: | By changing the dosage of composite coagulant, the treatment effect of preserved fruit wastewater by complex coagulation method was investigated. The results show that appropriate dose of the composite coagulant containing polymeric ferric sulfate and poly aluminum is 300 mg/L. After treating the preserved fruit wastewater with the compound coagulant, the sugar and salt removal rates can reach to 98.3% and 99.7%,respectively.Furthermore, the COD removal rate and the decolorization rate can reach to 99.6% and 96.9% respectively, treated wastewater can meet level 1 standard of "the integrated wastewater discharge standard" (GB8978-1996). |
