摘要:- 四川省內(nèi)江市某污水廠總處理規(guī)模為1.8×104 m3/d，一期工程處理規(guī)模為0.9×104 m3/d，原采用AAO-MBR為主體的污水處理工藝，出水水質(zhì)執(zhí)行《城鎮(zhèn)污水處理廠污染物排放標(biāo)準(zhǔn)》（GB 18918—2002）一級(jí)A標(biāo)準(zhǔn)。提標(biāo)改造工程處理規(guī)模不變，出水水質(zhì)要達(dá)到《四川省岷江、沱江流域水污染物排放標(biāo)準(zhǔn)》(DB 51/2311—2016)中城鎮(zhèn)污水處理廠排放標(biāo)準(zhǔn)�？偟陆抵�10 mg/L是關(guān)鍵技術(shù)難點(diǎn)，為此，采用AAOA-MBR強(qiáng)化脫氮工藝，主要通過(guò)改造AAO生物池?cái)U(kuò)大缺氧區(qū)容積、新增碳源投加系統(tǒng)、新增精確曝氣系統(tǒng)等措施，實(shí)現(xiàn)了在不新增土地、不停產(chǎn)情況下總氮的有效去除。工程建成投運(yùn)以來(lái)，運(yùn)行狀況良好，出水水質(zhì)穩(wěn)定達(dá)到設(shè)計(jì)標(biāo)準(zhǔn)。
Abstract:- The total treatment capacity of a wastewater treatment plant in Neijiang City, Sichuan Province is 1.8×104 m3/d, and the treatment capacity of the first phase project is 0.9×104 m3/d. The AAO-MBR was used as the original wastewater treatment process, and the effluent quality implemented the first class A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The treatment capacity of the upgrading project remains as same as the original project, and the effluent quality should meet the discharge standard of the municipal wastewater treatment plant in the Discharge Standard of Water Pollutants in Minjiang and Tuojiang River Basins of Sichuan Province (DB 51/2311-2016). The reduction of total nitrogen to 10 mg/L was the key technical difficulty. Therefore, the AAOA-MBR enhanced denitrification process was adopted to achieve the effective removal of total nitrogen without adding land or stopping production, mainly through the transformation of the AAO biological unit to expand the volume of the anoxic zone, addition of new carbon source dosing system, and adoption of new precise aeration system. Since the project was completed and put into operation, it has been in good operating condition, and the effluent quality has reached the design standard.
