【摘要】：老齡垃圾滲濾液由于其成分復(fù)雜、可生化性差,一直是污水處理中的難點(diǎn)。近年來興起的生物陰極型微生物燃料電池由于其建造成本相對便宜,并且陽極室、陰極室均具有去除底物污染物的能力,成為處理老齡垃圾滲濾液的一種有效新技術(shù)。本文通過構(gòu)建生物陰極型雙室微生物燃料電池,處理老齡垃圾滲濾液,研究了陽極與陰極面積比值和處理過的老齡垃圾滲濾液作為陰極液時(shí)對生物陰極型MFC的產(chǎn)電特征、陽極底物與陰極液處理效果的影響。電極面積是影響MFC性能的重要因素。實(shí)驗(yàn)結(jié)果表明,陽極與陰極面積比為1:2、2:2、2:1的三組生物陰極型微生物燃料電池輸出電壓分別為408、452、396m V,最大電功率密度分別為145.73、237.65、136.50m W/m3,內(nèi)阻分別為350、200、400Ω,COD的去除率分別為21.18%、20.20%、22.31%。三組微生物燃料電池運(yùn)行30d后,垃圾滲濾液中氨氮、硝酸鹽氮、亞硝酸鹽氮濃度均下降,其中氨氮去除率分別為80.88%、73.61%和66.17%,其去除效果與產(chǎn)電性能相關(guān)。陰極液是影響MFC性能的重要因素。實(shí)驗(yàn)結(jié)果表明,以處理過的老齡垃圾滲濾液作為陰極液的MFC,其COD、氨氮和硝酸鹽氮的去除率較傳統(tǒng)工藝分別提高了33.74%、44.32%和了17.92%;以體積比為75%的處理過的老齡垃圾滲濾液作為陰極液時(shí),能夠顯著提高M(jìn)FC的產(chǎn)電效果及系統(tǒng)的總氨氮去除量,輸出電壓和輸出功率密度均最大(分別為498m V和295.24m W/m3)、內(nèi)阻最小(244Ω)、總氨氮去除量最高(601mg);以體積比為50%的處理過的老齡垃圾滲濾液作為陰極液時(shí),能夠顯著提高M(jìn)FC系統(tǒng)的總硝酸鹽氮的去除量。
[Abstract]:Because of its complex composition and poor biodegradability, the aged landfill leachate has always been a difficult problem in wastewater treatment. In recent years, the biological cathode microbial fuel cell has been developed because of its relatively cheap construction cost and anode chamber. The cathode chamber has the ability to remove the substrate pollutants, which has become an effective new technology for the treatment of the leachate of the aged refuse. In this paper, the biocathode biofilm microorganism fuel cell is constructed to treat the leachate of the aged refuse. The electrogeneration characteristics of biocathode MFC were studied when the anodic to cathode area ratio and the treated landfill leachate were used as cathode solution. The effect of anode substrate and cathodic solution treatment. The electrode area is an important factor affecting the performance of MFC. The experimental results show that, The output voltages of the three groups of biological cathode microbial fuel cells with anodic to cathode area ratio of 1: 2: 2: 2: 1 were 408 / 4522 / 396mV, respectively, and the maximum electric power density was 145.73237.6N / 136.50m / m ~ (3), respectively. The removal rate of internal resistance of 350,200,400 惟 COD was 21.18 ~ 20.200.20 / 22.31respectively. After 30 days of operation, the three groups of microbial fuel cells had been operated for 30 days. The concentration of ammonia nitrogen, nitrate nitrogen and nitrite nitrogen in landfill leachate decreased. The removal rate of ammonia nitrogen was 80.88% 73.61% and 66.17%, respectively. The removal efficiency was related to the electrical properties. The cathode solution was an important factor affecting the performance of MFC. The experimental results showed that the concentration of ammonia nitrogen, nitrate nitrogen and nitrite nitrogen in landfill leachate were 80.88%, 73.61% and 66.17%, respectively. The removal rate of COD, ammonia nitrogen and nitrate nitrogen in the treated old landfill leachate as cathode fluid was increased by 33.744.32% and 17.92% respectively compared with the traditional process, while the treated old landfill leachate with volume ratio of 75% was used as cathode liquid, the removal rate of COD, ammonia nitrogen and nitrate nitrogen was increased by 33.744.32% and 17.92%, respectively, when the treated landfill leachate with volume ratio of 75% was used as cathode liquid, It can significantly improve the power generation effect of MFC and the removal of total ammonia nitrogen in the system. The output voltage and output power density are the highest (498mV and 295.24mW / m3, respectively), the minimum internal resistance is 244惟 ~ (-1), and the total ammonia nitrogen removal is the highest (601mgN). When the treated landfill leachate with volume ratio of 50% is used as cathode liquid, The removal rate of total nitrate nitrogen in MFC system can be increased significantly.
