【摘要】：針對(duì)單一蒸汽機(jī)械再壓縮(MVR)技術(shù)處理阻燃劑化工廢水能耗相對(duì)較高的問(wèn)題,采用電滲析(ED)耦合MVR技術(shù)的新型模式,對(duì)阻燃劑廢水進(jìn)行深度脫鹽及脫COD處理的同時(shí)降低系統(tǒng)總能耗。電滲析階段考察不同的水回收率、不同電壓及不同流量下的廢水處理效果;最終階段采用MVR工藝處理電滲析濃室產(chǎn)水,并對(duì)過(guò)程能耗模擬分析。結(jié)果表明,當(dāng)電滲析采用恒壓為25 V、體積流量為15 L/h、電滲析水回收率為67%時(shí),耦合工藝的總能耗與單一使用MVR相比降低了48.8%;同時(shí)整體工藝的水回收率提高至95%。
[Abstract]:Aiming at the problem of relatively high energy consumption in the treatment of flame-retardant chemical wastewater by single steam mechanical recompression (MVR) technology, a new model of MVR coupled with electrodialysis was adopted. The deep desalination and desalination of flame-retardant wastewater were carried out while the total energy consumption of the system was reduced. Different water recovery rates, different voltages and different flow rates were investigated in the electrodialysis stage. In the final stage, the MVR process was used to treat the water production in the electrodialysis concentrated chamber, and the energy consumption of the process was simulated. The results showed that when the constant pressure was 25 V, the volume flow rate was 15 L / h, and the recovery rate of the electrodialysis water was 67%, Compared with using MVR alone, the total energy consumption of the coupled process is reduced by 48.8%, and the water recovery rate of the whole process is increased to 95%.
