- 摘要:
- 常州某生活垃圾焚燒發(fā)電廠對收集的城鎮(zhèn)居民生活垃圾發(fā)酵腐熟以提高熱值，其間產(chǎn)生含高濃度有機物的滲濾液。滲濾液設計處理規(guī)模為300 m3/d，采用內(nèi)外循環(huán)厭氧反應器（IOC）—A/O—UF/NF/RO組合處理工藝，出水水質(zhì)執(zhí)行《城市污水再生利用 工業(yè)用水水質(zhì)》（GB/T 19923—2005）中敞開式循環(huán)冷卻水系統(tǒng)補充水水質(zhì)標準。IOC為企業(yè)自行研發(fā)的厭氧反應器，通過內(nèi)、外循環(huán)系統(tǒng)的結(jié)合更好地適應高濃度滲濾液的處理。外置式管式UF與生物處理A/O系統(tǒng)組成MBR系統(tǒng)，能很好地去除有機物和總氮，MBR出水再經(jīng)NF和RO處理后，保證最后出水水質(zhì)達標。運行結(jié)果表明，該工藝對COD、NH3-N、TN和TP的去除率分別為99.99%、99.98%、99.24%和99.98%，出水相應指標分別為4.6、0.24、12.4和0.014 mg/L，均優(yōu)于敞開式循環(huán)冷卻水水質(zhì)標準，可作補充水再利用。
Abstract:- In a certain domestic waste incineration power plant in Changzhou, the collected urban domestic wastes are fermented and decomposed to improve the calorific value, during which leachate containing high concentration of organic matter is produced. The leachate was treated by a combined process of inner and outer cycling anaerobic reactor (IOC), A/O, and UF/NF/RO with designed treatment capacity of 300 m3/d, and the effluent quality follows the standard of supplementary water quality for open type circulating cooling water system in The Reuse of Urban Recycling Water—Water Quality Standard for Industrial Uses(GB/T 19923-2005). The self-developed IOC can better adapt to the treatment of high concentration leachate through the combination of inner and outer circulation systems. The MBR system constituted with the external tubular UF and the biological treatment A/O system can remove organics and total nitrogen well. Then the MBR effluent is treated by nanofiltration and reverse osmosis to better ensure that the final effluent quality can better meet the standard requirements. It is found that the removal rates of COD, NH3-N, TN and TP are 99.99%, 99.98%, 99.24% and 99.98%, respectively, and the corresponding effluent values are 4.6, 0.24, 12.4 and 0.014 mg/L, respectively. These results are superior to the standard of the open type circulating cooling water quality, thereby the effluent can be reused for supplementary.
