论文在分析国内外涂装废水处理技术现状和发展方向基础上，主要做了以下几个方面的工作：复配一种有机/无机絮凝剂，并用阴离子聚丙烯酰胺凝聚处理油漆废水；合成水溶性三聚氰胺甲醛树脂并优化工艺，并与改性阳离子聚丙烯胺凝聚处理油漆废水；通过试验和探索，得出如下研究结果： （1）100mL 6%的聚合硫酸铁溶液，复配3g聚二甲基二烯丙基氯化铵溶液处理油漆废水，能有效的解除油漆的粘性。阴离子聚丙烯酰胺凝聚剂的最佳加入配比为1:3，按工艺条件和配方所制备的漆雾处理剂对油漆废水中水性油漆的除去率达到91.5%， （2）水溶性三聚氰胺甲醛树脂制备的适宜反应条件为: 原料比n(三聚氛胺): n(甲醛)= 1: 2时，羟甲基化反应(pH=8-9，40 min)、酸性缩聚反应(pH=3，3h)，温度均在70℃下进行。 （3）凝集剂由0.12wt%的改性剂改性分子量1200万，离子度50%的阳离子聚丙烯酰胺制得。 |

Based on the present situation of analyzing the coating wastewater treatment technology at home and abroad and development direction ,this paper mainly do the following several aspects: blends with a kind of organic/inorganic flocculant and deal with the paint wastewater using anionic polyacrylamide , synthesizing water-soluble melamine formaldehyde resin and optimizing the process and treat paint wastewater using modified cationic polypropylene amine agglomerate. Through experiment and exploration, draw the following research results: 1) 100 mL 6% of polyferric sulphate solution, blending with 3 g poly two methyl two allyl of dimethyldiallylammonium chloride solution is used for paint wastewater treatment, can effectively remove paint sticky. the best prepared ratio of Anionic polyacrylamide is 1:3, the treatment agent prepared according to the process conditions and the formula can remove 91.5% paint in the waste water . (2) suitable reaction condition for the preparation of water-soluble melamine formaldehyde resin: raw material ratio of n (3 get together the atmosphere amine) : n (formaldehyde) = 1:2, hydroxymethylation reaction (pH = 8 to 9, 40 min), acidic polycondensation reaction (pH = 3, 3 h), 70 ℃ . (3) NingJiJi is made by 0.12wt% modificated agent and the cationic PAM whose molecular weight is 12 million, ion degrees 50% . |
