在面對順酐廢水

In the face of maleic anhydride wastewater

順酐廢水主要特點是COD含量非常高、其內(nèi)的大分子污染物特別多、pH值低、營養(yǎng)物質(zhì)缺乏等,因此在使用傳統(tǒng)的廢水處理工藝是很難做到達標排放。

The main characteristics of maleic anhydride wastewater are high COD content, abundant macromolecular pollutants, low pH value, and lack of nutrients. Therefore, it is difficult to achieve standard discharge using traditional wastewater treatment processes.

例如某企業(yè)的順酐裝置排放的廢水是有三股,三股都不是“善茬”,其中離心機輕相廢水的水量和濃度都較高,COD濃度在26000mg/L-32000mg/L,其它廢水則是真空泵排放廢水,COD濃度都可以超過10000mg/L;

For example, the wastewater discharged from a certain enterprise's maleic anhydride plant consists of three streams, none of which are "good crops". Among them, the amount and concentration of the centrifuge light phase wastewater are relatively high, with a COD concentration of 26000mg/L-32000mg/L, while the other wastewater is discharged from a vacuum pump, with a COD concentration exceeding 10000mg/L;

而另一個企業(yè)的順酐裝置廢水是會排放出溶劑萃取離心分離廢水和切換冷卻器清洗廢水,COD濃度會超過40000mg/L,其內(nèi)的更是富含鄰苯二甲酸、富馬酸、馬來酸、焦油等污染物,處理難度巨大。

The wastewater from another enterprise's maleic anhydride plant will discharge solvent extraction centrifugal separation wastewater and switching cooler cleaning wastewater, with a COD concentration exceeding 40000 mg/L. The wastewater is also rich in pollutants such as phthalic acid, fumaric acid, maleic acid, tar, etc., making treatment difficult.

生物法是解決有機物的常見工藝:厭氧生物處理技術+好氧生物處理技術。

Biological method is a common process for solving organic matter: anaerobic biological treatment technology+aerobic biological treatment technology.

厭氧生物處理技術是可以做到提高可生化性,去除廢水當中的大分子污染物,并且COD去除率相對較高,可從COD濃度在7000mg/L降低1200mg/L(UASB反應器等)。它的處理是利用兼性厭氧菌和專性厭氧菌的共同作用,將廢水中的有機物分解并產(chǎn)生CO2,CH4等的一種生物處理技術,其具體過程是通過水解、發(fā)酵(或酸化)、產(chǎn)乙酸和產(chǎn)甲烷四個階段來達到去除有機物的目的。

Anaerobic biological treatment technology can improve biodegradability, remove macromolecular pollutants from wastewater, and have a relatively high COD removal rate, which can be reduced from a COD concentration of 7000mg/L to 1200mg/L (UASB reactor, etc.). Its treatment is a biological treatment technology that utilizes the combined action of facultative anaerobic bacteria and specialized anaerobic bacteria to decompose organic matter in wastewater and produce CO2, CH4, etc. The specific process is achieved through four stages: hydrolysis, fermentation (or acidification), acetic acid production, and methane production to remove organic matter.

與好氧生物處理技術相比,雖說厭氧生物處理具有不需充氧、能耗低、污泥量小等特點,但是厭氧反應器的啟動時間較長、出水水質(zhì)未能達到排放標準,需要配合好氧生物處理技術來完成廢水的凈化。

Compared with aerobic biological treatment technology, although anaerobic biological treatment has the characteristics of no need for oxygenation, low energy consumption, and small sludge volume, the start-up time of anaerobic reactors is longer, and the effluent quality does not meet the discharge standards. Therefore, it is necessary to cooperate with aerobic biological treatment technology to complete the purification of wastewater.

現(xiàn)在也有很多好氧生物處理技術可應用在濃度較高生物接觸氧化法、生物降解反應器系統(tǒng)(RBS)、深井曝氣法(DSP)和序批式活性污泥法(SBR)等。

There are also many aerobic biological treatment technologies that can be applied in high concentration biological contact oxidation, biodegradation reactor systems (RBS), deep well aeration (DSP), and sequencing batch activated sludge (SBR) processes.

生物接觸氧化法是生物膜法的一種。在生物接觸氧化法中,微生物主要以生物膜的狀態(tài)附著在固體填料上,有部分生物絮體呈破碎生物膜狀懸浮于處理水中,生物接觸氧化法中有機物的去除主要靠生物膜(附著微生物)的作用來完成。

Biological contact oxidation method is a type of biofilm method. In the biological contact oxidation method, microorganisms mainly adhere to solid fillers in the form of biofilms, and some biological flocs are suspended in the treated water in the form of broken biofilms. The removal of organic matter in the biological contact oxidation method mainly relies on the action of biofilms (attached microorganisms).

如果處理順酐廢水采用生物法進行降解的話,還需要針對廢水內(nèi)的情況,例如油脂、可生化性、偏酸性等問題,在生化處理階段前進行解決。

If biological degradation is used to treat maleic anhydride wastewater, it is necessary to address issues such as oil, biodegradability, and acidity in the wastewater before the biochemical treatment stage.
