順酐是一種重要的化工原料，在其生產(chǎn)過(guò)程中所產(chǎn)生的順酐廢水怎樣處理是化工廠所面臨的一個(gè)大問(wèn)題。隨著工作的不斷推進(jìn)，對(duì)順酐廢水處理工藝的研究也逐漸增多。例如如下一種處理順酐生產(chǎn)廢水的工藝，氫氧化鉀廠家來(lái)為您講解。

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.

在順酐廢水處理工藝中，先將順酐廢水進(jìn)入隔油池，去除廢水中上浮的大部分油類。然后將順酐廢水中加入強(qiáng)酸和異構(gòu)劑，并使混合物在58-63℃下進(jìn)行反應(yīng)30-40分鐘后，將混合物進(jìn)行降溫冷卻10-16℃后靜置15-18分鐘后，將混合物放入離心裝置內(nèi)進(jìn)行離心。

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.

再將離心后的反應(yīng)物放置反應(yīng)釜中，并向混合物中加入100℃的水，并對(duì)混合物進(jìn)行攪拌后，將混合物升溫105-116℃下進(jìn)行攪拌24-27分鐘后，向混合物中加入催化劑進(jìn)行攪拌并過(guò)濾后，向混合物中再次加入催化劑進(jìn)行攪拌并過(guò)濾后，將過(guò)濾物進(jìn)行降溫結(jié)晶后離心分離，并將分離后的混合物放入烘干裝置內(nèi)進(jìn)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.

離心后的離心液中加入混凝劑，并使混合物在30-34℃下進(jìn)行攪拌30-40分鐘，并控制溶液的pH為7-8，將混合放入過(guò)濾裝置內(nèi)進(jìn)行過(guò)濾，將過(guò)濾物放入離心萃取機(jī)內(nèi)，并向混合物加入萃取劑進(jìn)行反應(yīng)

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

將反應(yīng)后的離心萃取機(jī)下端的混合物放入在生物濾池內(nèi)進(jìn)行好氧發(fā)酵，并對(duì)混合物進(jìn)行降解。反應(yīng)后的離心萃取機(jī)上端的混合物中加入堿液進(jìn)行混合后，并對(duì)混合物進(jìn)行濃縮蒸餾，并對(duì)生成的混合物進(jìn)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.
