    下水生物学的処理水を対象として、オゾン/過酸化水素処理による有機物の分解実験を、半回分式実験装置を用いて行った。通気したオゾン濃度は50 mg/Lで、過酸化水素は初期に0、7.5、30、75または150 mg/Lを添加した。生物学的処理水の場合、初期過酸化水素濃度は30 mg/Lが最も速いTOC除去速度が得られ、反応器当たり0.08〜0.11 mg C/L/minであるのに対し、生物学的処理水の後段の急速砂ろ過塔でろ過した処理水の場合、初期に添加する過酸化水素濃度は7.5 mg/Lが最も速いTOC除去速度が得られ、0.19〜0.21 mg C/L/minであった。各々で単位TOC除去当たりの消費オゾン量は、26〜36 mg O3/mg Cおよび14〜15 mg O3/mg Cであった。また、生物学的処理水と生物学的処理水をガラス繊維ろ紙でSSを除去した処理水を用いた実験でも、SSを除去した処理水が速い除去速度が得られた。このことから、TOC除去速度はSSの存在が影響することがわかった。ろ過水では、1 mg/L程度までTOCが除去された。

    Two modified SBRs, specially configured to consist of both oxic and anoxic zones, and be operated with only a single simultaneous oxic/anoxic phase in each treatment batch, were tested to evaluate their applicability in the treatment of RLP wastewater. The effects of COD to TN ratio and their loading rates on the performance of the modified SBRs in the simultaneous removal of organic matter and nitrogen from RLP wastewater were investigated. It was observed that the performance of the two reactors in removal of COD and ammonium-N was similar, and did not remarkably change when varying the COD/TN ratio, as well as COD and TN loading rates in the ranges of 3.4-6.0 gCOD/gN, 0.8-1.7 kgCOD⋅m-3⋅d-1 and 0.15-0.34 kgN⋅m-3⋅d-1, respectively.

    An O3/H2O2 advanced oxidation process was experimentally examined for leaching radioactive cesium from contaminated sewage sludge since the excessive oxalic acid from the conventional method of coprecipitation with ferrocyanide complex salts disturbs the process of radioactive cesium removal. The most suitable condition for leaching radioactive cesium was a pH of 3, which subsequently mineralized the oxalic acid effectively. According to this study, 30 mg/L of hydrogen peroxide was an appropriate concentration. TOC was reduced from 100 mg/L to 40 mg/L within 40 minutes. The ozone requirement per TOC removal was 1.9 mgO3/mgC. Therefore, it proved that one molecule of ozone was needed to mineralize one molecule of oxalic acid. Oxalic acid was effectively decomposed at a pH of 3. Therefore, an O3/H2O2 dvanced oxidation process using a multistage reactor with 30 mg/L of hydrogen peroxide was recommended.

    Pilot tests of a cubic-lattice-based rotating biological contactor were implemented to remove organic matter from wastewater from a milk factory and a hospital in Vietnam. In the milk factory wastewater, the biochemical oxygen demand (BOD) removal ratio was stable between 60% and 90% (average 75%) using this method, with a BOD surface load of 0.002-0.020 kg•m-2•day-1. The average nutrient ratio of the raw wastewater was 0.13 of total nitrogen and 0.015 of total phosphorus compared with 1.0 of BOD. The BOD of treated water was less than 50 mg•L-1, achieving category B of the industrial wastewater standard of Vietnam (QCVN 40:2011). For the hospital wastewater, the BOD removal ratio was stable between 60% and 90% (average 78%), with a BOD surface load of 0.005-0.022 kg•m-2•day-1. The average nutrient ratio of the raw wastewater was 0.25 of total nitrogen and 0.018 of total phosphorus compared with 1.0 of BOD. The BOD of treated water was less than 50 mg•L-1, satisfying category B of the medical wastewater standard of Vietnam (QCVN 28:2010/BTNMT). The electric power consumption was 0.73 KWh•m-3 of wastewater. The sludge conversion ratio from BOD was 0.51 kg TSS•kg BOD-1 based on the excess sludge and suspended solids in raw wastewater and treated water.

    We have worked on the development of a biological filtration system utilizing indigenous bacteria to remove arsenite, arsenate, iron, manganese and ammonia from groundwater. Among various bacteria, iron bacteria (bacterial species that biologically oxidize dissolved Fe and/or Mn, and deposit them as oxides) together with nitrifiers play the most important role in our system. This report is a brief summary of our pilot study (started in 2004), treating groundwater by the biological filtration. The purpose is to determine the optimal operating conditions to achieve the most efficient removal of arsenic.

    The purpose of this study is to remove pollution matter such as organic matter and nutrients from sewage using a bio film method with string media and then to recover the phosphorus from the used string media. The activated sludge method is the most popular method for sewage treatment. However this method produces a lot of excess sludge and increases the costs of the sewage treatment facility. The results of our experiments on removal of organic matter show that a bio film method using string bio film media can remove organic matters in sewage. Sewage also contains high concentrations of phosphorus, which should be removed to improve the treated water quality but is an important nutrient in agriculture. Since phosphorous becomes depleted in soil by agricultural activity, it must be added regularly to maintain soil fertility. This makes recovered phosphorous a valuable by-product of sewage treatment. This study therefore also evaluated phosphorus recovery from the used string media with hot water and confirmed the possibility of phosphorous recovery by that method.

    本研究は、回分式実験によりオゾンと4種の人工甘味料の反応量論について検討した。初期人工甘味料濃度を0.2 mmol/L、オゾン水濃度を0.0015〜0.0096 mmol/Lとして2分間反応させた。スクラロースについてはほとんど分解せず、オゾンの減少も少なかったことからほとんど反応が起こっていないと考えられた。サッカリン二水和物、アスパルテーム、アセスルファムカリウムは、オゾン1 molに対して、それぞれ0.92 mol、ア0.67 mol、1.1 mol分解することが確認できた。

    Even though O3/H2O2 based AOP has been proven to be an effective polishing treatment for sewage effluent, some of organic compounds were still found after treatment as the TOC value of treated sample was around 1 mg/L. In pursue of identifying these remaining substances, High Performance HPSEC-OCD was used to determine range of AMW of the remaining substances. In this study, four HPSEC-OCD results were observed and compared: (a) sewage effluent before AOP, (b) after ozone only treatment, (c) after ozonation with hydrogen peroxide addition in the beginning, (d) after ozonation with hydrogen peroxide continuously added. HPSEC-OCD chromatograms show that biopolymer in AMW range of 30,000 Da and LMW neutrals in AMW range of 500 Da were removed in all cases. However, humic substances and building blocks in AMW range of 2,700 and 2,000 Da are only removed in presence of hydrogen peroxide. LMW acids in which has AMW range of 1,100-1,200 Da were found irremovable. Furthermore, concentration in this AMW range increased after all treatment. The increase was hypothesized to be by-products of AOP reactions with larger molecules.

    An O3/H2O2 advanced oxidation process was experimentally examined to decompose oxalic acid. The method used was an adaptation of H2O2 decomposition via a continuous adding method to our reactor. As compared with the method of adding H2O2 at one time just before the start of the experiment and at two steps which have been carried out in the previous research, the degradation rate of TOC more continues at 1.0-2.0 mgC/L/min under the condition of pH3 and at 0.5-1.0 mgC/L/min under the condition of pH 7 during the experiment time.

    An O3 oxidation process and an O3/H2O2 advanced oxidation process were experimentally examined to decompose artificial sweeteners, which have the tendency to accumulate in ambient water. The artificial sweeteners examined in this experiment were saccharin sodium dihydrate, sucralose, aspartame, and acesulfame K. Decomposition of these sweeteners was achieved via both an O3 oxidation process and an O3/H2O2 advanced oxidation process. However, our results showed that organic byproducts were formed using both the processes.

    As a follow up to our previously reported work, an O3/H2O2 advanced oxidation process was experimentally examined for the decomposition of oxalic acid. This process was an adaptation of the step addition process previously reported for H2O2 in our reactor. In this study, not only TOC decomposition rate but also ozone consumption rate and hydrogen peroxide consumption rate are compared. And additionally following experiment was conducted in which under the experiment condition of pH 3, pH is readjusted at 3 when hydrogen peroxide is added at the second step. As a result, it was found that decomposition progressed more than the experiment when not added by two steps.

    As a follow up to our previously reported work, an advanced oxidation process involving O3/H2O2 was examined for decomposing organic matter in the effluent obtained from a final sedimentation tank, which was a part of the biological treatment process for sewage. The experiment was conducted using three addition methods of H2O2, which were addition at the beginning once, two-steps addition and continuance addition. The rate of decomposition was evaluated by calculating the rates of TOC decomposition, O3 consumption and H2O2 consumption. In case of this study, the continuance addition method decreased to 3.0 mgC/L, it was the lowest in the other methods.

    Three O3/metal advanced oxidation processes were examined to decompose oxalic acid and acetic acid. The metals used were iron, aluminum, and manganese and each process was tested under pH7 and pH3 conditions. Oxalic acid was hardly decomposed with iron and aluminum under pH7 or pH3 conditions, however it was highly decomposed with manganese under pH3 conditions. Acetic acid was not decomposed with any metal under pH7 conditions. Thus, we conclude that oxalic acid is decomposed when permanganate ions react with hydrogenoxalate ions.

    An O3/H2O2 advanced oxidation process was experimentally examined to decompose oxalic acid. Organic byproducts and mineralized oxalic acid were measured using a total organic carbon (TOC) analyzer and ion-chromatography under pH7 and pH3 conditions. The resulting data show that the removal rate of TOC was nearly equal to the removal rate of oxalic ions and hence, oxalic acid was almost completely mineralized by the O3/H2O2 advanced oxidation process.

    We have previously decomposed oxalic acid using an O3/H2O2 advanced oxidation process, where ozone gas feeds continuously, hydrogen peroxide is introduced immediately before the experiment, and sample water is introduced in batches (called a semibatch process). In this study, we use a semibatch approach again, but hydrogen peroxide is introduced twice; once immediately before the experiment and once during the experiment, after the first batch has been used. The resulting data show that this approach has a higher rate of TOC removal, even with the same quantity of hydrogen peroxide.

    An O3/H2O2 advanced oxidation process was experimentally examined to remove decomposing organic matter from sedimentation tank effluents of a biological sewage treatment plant. The effluents were obtained from a sewage treatment plant in the Kansai region, Japan, and filtered through a glass fiber filter to remove suspended solids. The resulting data show that suspended solids disturb the decomposition of organic matter in the effluents by forming HO radicals from ozone and hydrogen peroxide.

    An O3/H2O2 advanced oxidation process was experimentally examined for decomposing oxalic acid and acetic acid. Regarding sample water with 7.5 mg/L of hydrogen peroxide under pH3, oxalic acid as TOC was decomposed effectively. Regarding sample water with 150 mg/l of hydrogen peroxide, decomposition rate was reduced compared the water with 7.5 mg/L of hydrogen peroxide. Acetic acid was decomposed well, adding hydrogen peroxide more and taking decomposing time more under pH7. It was not decomposed under pH3.
