对顺酐生产废水的来水行隔油处理，即设置或配备一座/多座隔油调节池，通过重力流的方式将浮油截留一个隔油池中，定期进行处理；隔油调节池出水则投加强酸及异构剂药剂在58℃-63℃下进行反应半小时，再降温冷却使废水中的顺丁烯二酸形成富马酸，富马酸在高温下会溶解，因此可通过对废水进行加热，而后在进入二级处理工艺进行处理。

98彩票The incoming water from the production of maleic anhydride should be treated with oil separation first, that is, one or more oil separation regulating tanks should be set up or equipped, and the floating oil should be intercepted into an oil separation tank through gravity flow for regular treatment; The effluent from the oil separation regulating tank is treated with strengthening acid and isomer agents at 58 ℃ -63 ℃ for half an hour, followed by cooling to form fumaric acid from the maleic acid in the wastewater. fumaric acid dissolves at high temperatures, so the wastewater can be heated and then treated in the secondary treatment process.

二级处理考虑土建成本、设备投入成本及药剂成本，选用生化处理，即厌氧处理工艺的不完全厌氧——水解酸化工艺、完全厌氧反应处理——厌氧反应池和接触氧化方式或活性污泥处理方式的好氧处理。在以往的废水处理中通过抽样对顺酐废水好氧出水进行检测，其中COD、氨氮等污染物指标都明显降低，可达到业主要求的排放标准。若标准较严者，则可考虑加深度处理配合使用，如混凝终沉、微电解反应罐等方式进行配合处理，确定处理后废水能稳定、持续地达标排放。具体使用哪种顺酐废水处理工艺或哪几种工艺结合处理可根据实际情况进行一对一针对处理制定。

The secondary treatment considers civil engineering costs, equipment input costs, and chemical costs, and selects biochemical treatment, namely incomplete anaerobic hydrolysis acidification process of anaerobic treatment process, complete anaerobic reaction treatment anaerobic reaction tank, and aerobic treatment of contact oxidation or activated sludge treatment method. In previous wastewater treatment, aerobic effluent from maleic anhydride wastewater was tested through sampling, and pollutant indicators such as COD and ammonia nitrogen were significantly reduced, meeting the discharge standards required by the owner. If the standard is stricter, it can be considered to use advanced treatment in combination, such as coagulation final sedimentation, micro electrolysis reaction tank, etc., to ensure that the treated wastewater can be stably and continuously discharged to meet the standard. The specific treatment process for maleic anhydride wastewater or the combination of several processes can be developed one-on-one according to the actual situation.

顺酐是一种重要的化工原料，其生产过程中会产生一定的废水，废水中含有顺酸、乙酸、丙烯酸等有机污染物，COD浓度值高，且废水的可生化性欠缺，由于废水中高COD浓度值会对水处理过程中的微生物有强烈的抑制作用，因此，在水处理过程中应先将废水中不可溶性的有机物通过破坏其链状或环状的连接键断开，从而使水处理的微生物对其处理难度降低；生产来水中会有部分的油类物质，需对其油类物质进行截留。

Maleic anhydride is an important chemical raw material, which generates a certain amount of wastewater during its production process. The wastewater contains organic pollutants such as maleic acid, acetic acid, acrylic acid, etc. The COD concentration value is high, and the biodegradability of the wastewater is insufficient. Due to the strong inhibitory effect of high COD concentration in the wastewater on microorganisms in the water treatment process, therefore, In the process of water treatment, insoluble organic matter in wastewater should be first broken by breaking its chain or ring like connection bonds, so as to reduce the difficulty of microbial treatment of water treatment; There will be some oily substances in the incoming water during production, and their oily substances need to be intercepted.
