- 摘要:
- 北京市某再生水廠設(shè)計(jì)規(guī)模為8×104 m3/d，出水水質(zhì)執(zhí)行北京市地方標(biāo)準(zhǔn)《城鎮(zhèn)污水處理廠水污染物排放標(biāo)準(zhǔn)》（DB 11/890—2012）A標(biāo)準(zhǔn)。該廠采用多段進(jìn)水A2O+MBR工藝作為主處理工藝，由于其出水COD很難穩(wěn)定達(dá)到京標(biāo)A標(biāo)準(zhǔn)的要求（COD≤20 mg/L），需增加COD深度處理單元。對(duì)目前可選擇的深度處理工藝——臭氧催化氧化、脈沖炭吸附、下向流炭吸附及活性焦吸附工藝就占地面積、投資、運(yùn)行成本及工藝的實(shí)際應(yīng)用情況進(jìn)行了比較。結(jié)果表明,臭氧催化氧化工藝占地面積最小，脈沖炭吸附和下向流炭吸附工藝初期投資較低，活性焦吸附及下向流炭吸附工藝運(yùn)行成本更低。臭氧催化氧化、脈沖炭吸附、活性焦吸附工藝均有實(shí)際應(yīng)用案例。綜合考慮，最終確定脈沖炭吸附和活性焦吸附工藝是現(xiàn)階段較好的COD深度處理把關(guān)工藝。
- Abstract:
- The effluent of a reclaimed water plant in Beijing, with a design scale of 8 ×104 m3/d, implemented class A standard of Beijing local standard Discharge Standard of Water Pollutants for Municipal Wastewater Treatment Plants (DB 11/890-2012) (Beijing standard A). It was proposed to adopt multi-stage water inlet A2O+MBR process. Because it was difficult for the effluent COD to stably meet the requirements of the Beijing standard A(COD≤20 mg/L), advanced COD removal processing unit ought to be added. The theoretically feasible methods, such as the ozone catalytic oxidation, the pulsed carbon adsorption tank, the downflow carbon adsorption tank and the activated coke adsorption bed process, were compared in terms of land occupation, investment, operating cost and practical application of the process. The results showed that ozone catalytic oxidation covers the smallest area. The initial investment of the pulsed carbon adsorption tank and the downflow carbon adsorption tank was lower, and the operating cost of the activated coke adsorption bed and the down-flow carbon adsorption tank was lower. The ozone catalytic oxidation, the pulsed carbon adsorption tank, the active coke adsorption bed had practical application cases of the wastewater plant. Considering the above factors, it was concluded that the processes of pulsed carbon adsorption and activated coke adsorption were the better processes for COD removing advanced treatment at present.
