Embodiment 1
[0044] Embodiment 1: a kind of treatment method of diketene production waste water, comprises the following steps:
[0045] (1) Hydrolysis
[0046] Mix the rectification residue and waste liquid produced by the acetic acid cracking method to prepare diketene as wastewater to be treated; add water, disodium EDTA, low molecular weight sodium polyacrylate and sodium dodecylsulfonate to the wastewater to be treated, and stir at room temperature reaction, collect the CO produced by the reaction 2 , until the reaction is free of CO 2 produce;
[0047] On a mass basis, the ratio of waste water to be treated, water, disodium EDTA, low molecular weight sodium polyacrylate and sodium dodecylsulfonate is 1:2.0:0.02:0.25:0.05;
[0048] (2) Separation of acetone
[0049] Distill the slurry obtained in step (1) at a distillation temperature of 45° C., and collect the distilled gas into an acetone receiving tank after condensation;
[0050] (3) Dehydration
[0051] Concentrate the slur...
