顺酐是一种重要的化工原料，在其生产过程中所产生的顺酐废水怎样处理是化工厂所面临的一个大问题。随着工作的不断推进，对顺酐废水处理工艺的研究也逐渐增多。例如如下一种处理顺酐生产废水的工艺，氢氧化钾厂家来为您讲解。

Maleic anhydride is an important chemical raw material. How to treat maleic anhydride wastewater produced in its production is a big problem faced by chemical plants. With the continuous advancement of environmental protection, the research on maleic anhydride wastewater treatment process has gradually increased. For example, the following process for treating maleic anhydride production wastewater will be explained by the potassium hydroxide manufacturer.

在顺酐废水处理工艺中，先将顺酐废水进入隔油池，去除废水中上浮的大部分油类。然后将顺酐废水中加入强酸和异构剂，并使混合物在58-63℃下进行反应30-40分钟后，将混合物进行降温冷却10-16℃后静置15-18分钟后，将混合物放入离心装置内进行离心。

In the maleic anhydride wastewater treatment process, maleic anhydride wastewater is first sent to the oil separator to remove most of the oil floating in the wastewater. Then, strong acid and isomer are added to maleic anhydride wastewater, and the mixture is allowed to react at 58-63 ℃ for 30-40 minutes. Then, the mixture is cooled down to 10-16 ℃ and allowed to stand for 15-18 minutes. Then, the mixture is put into a centrifugal device for centrifugation.

再将离心后的反应物放置反应釜中，并向混合物中加入100℃的水，并对混合物进行搅拌后，将混合物升温105-116℃下进行搅拌24-27分钟后，向混合物中加入催化剂进行搅拌并过滤后，向混合物中再次加入催化剂进行搅拌并过滤后，将过滤物进行降温结晶后离心分离，并将分离后的混合物放入烘干装置内进行烘干干燥。

Then put the centrifuged reactant into the reaction kettle, add water at 100 ° C to the mixture, stir the mixture, raise the temperature of the mixture to 105-116 ° C, stir for 24-27 minutes, add catalyst to the mixture, stir and filter, add catalyst to the mixture again, stir and filter, lower the temperature of the filter, crystallize and centrifuge it, And put the separated mixture into a drying device for drying.

离心后的离心液中加入混凝剂，并使混合物在30-34℃下进行搅拌30-40分钟，并控制溶液的pH为7-8，将混合放入过滤装置内进行过滤，将过滤物放入离心萃取机内，并向混合物加入萃取剂进行反应

Add coagulant to the centrifugal liquid after centrifugation, stir the mixture at 30-34 ℃ for 30-40 minutes, and control the pH of the solution to 7-8. Put the mixture into the filter device for filtration, put the filter into the centrifugal extractor, and add extractant to the mixture for reaction

将反应后的离心萃取机下端的混合物放入在生物滤池内进行好氧发酵，并对混合物进行降解。反应后的离心萃取机上端的混合物中加入碱液进行混合后，并对混合物进行浓缩蒸馏，并对生成的混合物进行回收。

The mixture at the lower end of the centrifugal extractor after reaction is put into the biological filter for aerobic fermentation, and the mixture is degraded. After the reaction, alkali liquor is added to the mixture at the upper end of the centrifugal extractor for mixing, the mixture is concentrated and distilled, and the resulting mixture is recovered.
