Advantages of intermittently aerated SBR over conventional SBR on nitrogen removal for the treatment

Xiaoyan Song, Rui Liu, Lujun Chen, Baogang Dong, Tomoki Kawagishi

《环境科学与工程前沿（英文）》 2017年 第11卷 第3期 doi: 10.1007/s11783-017-0941-7

摘要： An intermittently aerated sequencing batch reactor (IASBR) and a traditional sequencing batch reactor (SBR) were parallelly constructed to treat digested piggery wastewater, which was in high NH -N concentration but in a low COD/TN ratio. Their pollutant removal performance was compared under COD/TN ratios of 1.6–3.4 d and hydraulic retention times of 5–3 d. The results showed that the IASBR removed TN, NH -N and TOC more efficiently than the SBR. The average removal rates of TN, NH -N and TOC were 83.1%, 96.5%, and 89.0%, respectively, in the IASBR, significantly higher than the corresponding values of 74.8%, 82.0%, and 86.2% in the SBR. Mass balance of organic carbon revealed that the higher TN removal in the IASBR might be attributed to its efficient utilization of the organic carbon for denitrification, since that 48.7%–52.2% of COD was used for denitrification in the IASBR, higher than the corresponding proportion of 43.1%–47.4% in the SBR. A pre-anoxic process in the IASBR would enhance the ammonium oxidation while restrict the nitrite oxidation. Anoxic duration of 40–80 min should be beneficial for achieving stable nitritation.

Comparative study on microbial community in intermittently aerated sequencing batch reactors (SBR) anda traditional SBR treating digested piggery wastewater

Xiaolin Sheng, Rui Liu, Xiaoyan Song, Lujun Chen, Kawagishi Tomoki

《环境科学与工程前沿（英文）》 2017年 第11卷 第3期 doi: 10.1007/s11783-017-0929-3

摘要： A traditional sequencing batch reactor (SBR) and two intermittently aerated sequencing batch reactors (IASBRs) were parallelly operated for treating digested piggery wastewater. Their microbial communities were analyzed, and the nitrogen removal performance was compared during the long–term run. IASBRs demonstrated higher removal rates of total nitrogen (TN) and ammonium nitrogen (NH -N) than the SBR, and also demonstrated higher resistance against TN shock load. It was found that the more switch times between aerobic/anoxic in an IASBR, the higher the removal rates of TN and NH –N. All the reactors were predominated by , and , which were considered to be species of denitrifiers, ammonium oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB), respectively. However, the abundance and diversity was of great difference. Compared with SBR, IASBRs achieved higher abundance of denitrification–related bacteria. IASBR 1 with four aerobic/anoxic switch times was detected with 25.63% of , higher than that in IASBR 2 with two aerobic/anoxic switch times (11.57% of ), and much higher than that in the SBR (only 6.19% of ). IASBR 2 had the highest percentage of AOB, while IASBR 1 had the lowest percentage. The denitrifiers abundance was significantly positive correlated with the TN removal rate. However, the NH –N removal rate showed no significant correlation with the AOB abundance, but might relate to the AOB activity which was influenced by the average free ammonium (FA) concentration. was the only NOB genus detectable in all reactors, and were less than 0.03%.

Optimization of phosphorus removal in uniFed SBR system for domestic wastewater treatment

Xuguang TANG, Shuying WANG, Yongzhen PENG

《环境科学与工程前沿（英文）》 2010年 第4卷 第4期   页码 475-481 doi: 10.1007/s11783-010-0244-8

摘要： The characteristic of phosphorus removal and appropriate change of the traditional operation modes were investigated in UniFed sequencing batch reactor (SBR) laboratory-scale apparatus (40 L), treating actual domestic wastewater with low ratios of C/N (2.57) and C/P (30.18), providing theoretical basis for actual application of wastewater treatment plant. UniFed SBR system with its unique operation mode had the distinct superiority of phosphorus removal. On this occasion, the effect of volumetric exchange ratio (VER) and the method of influent introduction for phosphorus removal were studied. When the carbon source became the limiting factor to phosphorus release, the higher the VER, the lower the phosphorus concentration in the effluent. Three different influent patterns, including one-time filling, four-time filling, and continuous filling with the same quantity of wastewater could increase the release rate of anaerobic phosphorus from 0.082 to 0.143 mg·P·(L·min) . Appropriate change of the traditional operation modes could optimize the efficiency of phosphorus removal. When the feed/ decant time was extended from 2 h to 4 h, the phosphorous removal efficiency increased from 59.93% to 88.45% without any external carbon source. In the mode of alternation of anoxic-aerobic (A/O) condition, phosphorous removal efficiency increased from 55.07% to 72.27% clearly. The carbon source in the influent can be used adequately, and denitrifying phosphorus removal was carried out in anoxic stage 2 (A2). This mode was optimal for the treatment of actual domestic wastewater with low C/N and C/P ratios.

Advanced nitrogen removal using pilot-scale SBR with intelligent control system built on three layer

YANG Qing, WANG Shuying, YANG Anming, GUO Jianhua, BO Fengyang

《环境科学与工程前沿（英文）》 2007年 第1卷 第1期   页码 33-38 doi: 10.1007/s11783-007-0006-4

摘要： Since eutrophication has become increasingly severe in China, nitrogen and phosphorous have been the concern of wastewater treatment, especially nitrogen removal. The stabilization of the intelligent control system and nitrogen removal efficiency were investigated in a pilot-scale aerobic-anoxic sequencing batch reactor (SBR) with a treatment capacity of 60 m/d. Characteristic points on the profiles of dissolved oxygen (DO), pH, and oxidation reduction potential (ORP) could exactly reflect the process of nitrification and denitrification. Using the intelligent control system not only could save energy, but also could achieve advanced nitrogen removal. Applying the control strategy water quality of the effluent could stably meet the national first discharge standard during experiment of 10 months. Even at low temperature ( = 13vH), chemical oxygen demand (COD) and total nitrogen (TN) in the effluent were under 50 and 5 mg/L, respectively.

controlling system for nitrogen and phosphorus removal of municipal wastewater in a sequencing batch reactor (SBR

LI Jun, NI Yongjiong, WEI Su, CHENG Guobiao, OU Changjin, PENG Yongzhen, GU Guowei, LU Jingen

《环境科学与工程前沿（英文）》 2008年 第2卷 第1期   页码 99-102 doi: 10.1007/s11783-008-0017-9

摘要： The objectives of this study were to establish an on-line controlling system for nitrogen and phosphorus removal synchronously of municipal wastewater in a sequencing batch reactor (SBR). The SBR for municipal wastewater treatment was operated in sequences: filling, anaerobic, oxic, anoxic, oxic, settling and discharge. The reactor was equipped with on-line monitoring sensors for dissolved oxygen (DO), oxidation-reduction potential (ORP) and pH. The variation of DO, ORP and pH is relevant to each phase of biological process for nitrogen and phosphorus removal in this SBR. The characteristic points of DO, ORP and pH can be used to judge and control the stages of process that include: phosphate release by the turning points of ORP and pH; nitrification by the ammonia valley of pH and ammonia elbows of DO and ORP; denitrification by the nitrate knee of ORP and nitrate apex of pH; phosphate uptake by the turning point of pH; and residual organic carbon oxidation by the carbon elbows of DO and ORP. The controlling system can operate automatically for nitrogen and phosphorus efficiently removal.

Simultaneous denitrifying phosphorus accumulation in a sequencing batch reactor

YUAN Linjiang, HAN Wei, WANG Lei, YANG Yongzhe, WANG Zhiying

《环境科学与工程前沿（英文）》 2007年 第1卷 第1期   页码 23-27 doi: 10.1007/s11783-007-0004-6

摘要： In order to achieve simultaneous nitrogen and phosphorus removal in the biological treatment process, denitrifying phosphorus accumulation (DNPA) and its affecting factors were studied in a sequencing batch reactor (SBR) with synthetic wastewater. The results showed that when acetate was used as the sole carbon resource in the influent, the sludge acclimatized under anaerobic/aerobic operation had good phosphorus removal ability. Denitrifying phosphorus accumulation was observed soon when fed with nitrate instead of aeration following the anaerobic stage, which is a vital premise to DNPA. If DNPA sludge is fed with nitrate prior to the anaerobic stage, the DNPA would weaken or even disappear. At the high concentration of nitrate fed in the anoxic stage, the longer anoxic time needed, the better the DNPA was. Induced DNPA did not disappear even though an aerobic stage followed the anoxic stage, but the shorter the aerobic stage lasted, the higher the proportions of phosphorus removal via DNPA to total removal.

Effects of shear force on formation and properties of anoxic granular sludge in SBR

Xinyan ZHANG, Binbin WANG, Qingqing HAN, Hongmei ZHAO, Dangcong PENG

《环境科学与工程前沿（英文）》 2013年 第7卷 第6期   页码 896-905 doi: 10.1007/s11783-013-0539-7

摘要： This paper reports the effects of shear force on anoxic granular sludge in sequencing batch reactors (SBR). The study was carried out in two SBRs (SBR1 and SBR2) in which sodium acetate (200 mg COD·L ) was used as the sole substrate and sodium nitrate (40 mgNO -N·L ) was employed as the electron acceptor. The preliminary objective of this study was to cultivate anoxic granules in the SBR in order to investigate the effects of shear force on the formation of anoxic granular sludge and to compare the properties of anoxic sludge in the SBR. This study reports new results for the values of average velocity gradient, a measure of the applied shear force, which was varied in the two SBRs (3.79 s and 9.76 s for SBR1 and SBR2 respectively). The important findings of this research highlight the dual effects of shear force on anoxic granules. A low shear force can produce large anoxic granules with high activity and poor settling ability, whereas higher shear forces produce smaller granules with better settling ability and lower activity. The results of this study show that the anoxic granulation is closely related to the strength of the shear force. For high shear force, this research demonstrated that: 1) granules with smaller diameters, high density and good settling ability were formed in the reactor, and 2) granular sludge formed faster than it did in the low shear force reactor (41days versus 76 days). Once a steady-state has been achieved, the nitrate and COD removal rates were found to be 98% and 80%, respectively. For low shear force, such as was applied in SBR1, this research demonstrated that: 1) the activity of anoxic granular sludge in low shear force was higher than that in high shear force, 2) higher amount of soluble microbial products (SMPs) were produced, and 3) large pores were observed inside the larger granules, which are beneficial for nitrogen gas diffusion. Electron microscopic examination of the anoxic granules in both reactors showed that the morphology of the granules was ellipsoidal with a clear outline. Coccus and rod-shaped bacteria were wrapped by filamentous bacteria on the surface of granule.
