Anaerobic treatment is widely used around the world as a biological stage in both domestic and industrial wastewater-treatment plants. The two principal advantages of anaerobic over aerobic treatment are the production of biogas, which can be used as fuel, and the lower rate of biomass production, which results in lower maintenance costs for the plant. The upflow anaerobic sludge blanket (UASB) reactor is an attractive alternative for regions in hot climates since it works better under mesophilic conditions and it does not need any supporting structure for the development of microorganisms, wh

Additionally, grain distillery wastewater (GDWW) is high in fats, oils and grease (FOG) which can cause problems during AD.

碩士<br>崑山科技大學<br>環境工程研究所<br>99<br>The dyeing industry is a complicated process, intensive and professional technology. With characteristics of large wastewater discharge and high concentration of pollution, the impact on the environment is obvious and serious. In the past decades, the research and development of synthetic pulps and dyeing assistants result in the challenge of wastewater treatment. The problems of un-efficient treatment and high cost of wastewater treatment always bother the industrial development. One of the alternatives to resolve the problem is to develop the module of series

Abstract:

The start-up of two upflow anareobic sludge blanket (UASB) reactors seeded with aerobic activated sludge and treating brewery wastewater is presented in this thesis. Both reactors were identical in design and were continuously operated at 19 - 23 ° C. Reactor A was seeded with 1.98 g VSS/1 of reactor, while Reactor B was seeded with 5.93 g VSS/1 of reactor. The reactors were first operated at a hydraulic retention time of 5 days. The hydraulic retention time was then reduced in a step-wise fashion to 3 days, 1.5 days, 18 hours then 12 hours in order to increase the organic loading rate.

碩士<br>國立成功大學<br>環境工程學系碩博士班<br>92<br>Four upflow anaerobic sludge bed (UASB) reactors with effluent recycle (superficial velocity us = 2.0 m/h, operating temperature = 35℃) were used to treat sulfate-laden tannery wastewater. At the volumetric loading rates (VLRs) of 1.06, 2.12, 3.17, and 4.23 kg COD/m3-d (COD/SO42- = 0.7) and without internal sulfide oxidation (ORP = (-375)－(-395) mV), the COD removal efficiencies were 86.7－88.0% and the sulfides and unionized H2S effluent concentrations (i.e., an inhibitory substance onto anaerobic microorganisms) were 303－311 and 31－44 mg S/L, respectively.

碩士<br>崑山科技大學<br>機械工程研究所<br>100<br>This work presents the performance of intermittent recirculation for the treatment of cow wastewater by a 11.4L bench scale upflow anaerobic sludge blanket (UASB) reactor. It was operated at room temperature (13.6 -27.8°C) with 1.1-5.1 kg COD/m3-d of organic loading for 186 days. At the start up period the reactor was operated with 0.127 m/hr superficial velocity by continuing recirculation. However the UASB reactor exhibited inoperable conditions due to the sludge bed expansion to the top of the reactor. Therefore we proposed the new four operation modes by s

The treatment efficiency and the Daphnia acute toxicity of the effluent of a biological system were tested and discussed. The main operation factors in treatment systems were the pH and hydraulic retention time (HRT) in all tests. According to the results of effluent bio toxicity after the treatment, we found when
