Stage Process

Anaerobic fermentative technology is an important route to solving environmental pollution and resources problems. Combined hydrogen and methane production in a two-stage process is a concept which has been developed in recent years Anaerobic biological treatment organic wastewater can produce large amounts of hydrogen and methane，which can be used as energy carrier. At present，the research focusing on the adjustment of fermentation hydrogen-methane production has been conducted. Furthermore, the simultaneous hydrogen-methane production was tested and optimized. However, it lacked combined hydrogen-methane production in an anaerobic reactor in literature so far. Based on preview experiment, the paper studied the simultaneous hydrogen-methane fermentation in an anaerobic baffled reactor (ABR) system. ABR has the advantage of biomass phase separation and integration of acidogenic and methanogenic processes to simultaneously conduct hydrogen-methane production during wastewater treatment. Through deep biohydrogen production, it can enhance the activity of hydrogen-producing acetogens (HPA) and the efficiencies of the combined hydrogen-methane fermentation system. It showed to enhance the activity of HPA was the key to the combined hydrogen-methane production.

Aiming at the fact that the low concentration sewage in small cities, this paper presents Two-phase Anaerobic Baffled Reactor (TAABR) for living wastewater treatment, importantly, it designs and researches Two-phase Anaerobic Baffled Reactor and its advantages, designs a trial project according to the characteristics of the reactor equip. The experiment uses the method that by shortening HRT to raise the load to start and analyses the operating results during startup as follows: 1. 53 days later anaerobic reactor start-up successes.2. When the load is 0.5kgCOD/m3.d, the removal rate of COD is more than 80%. 3. PH value is not the main limiting factors during start up in the reactor and there is basically no danger of excessive acidification.

This paper presented Low investment and low running cost Two-phase Anaerobic Baffle Treatment Craft for living wastewater treatment, it designed Two-phase anaerobic reactor and carried out a successful launch and Experiment research. The results are as follows: 1. The experiment uses the start method that by shortening HRT to raise the load, after 53 days completes experiment start.2. By the analysis of HRT to the system effect, suggest that the best HRT is 6 h when the craft processes sewage. 3. The system clean rates of the total nitrogen and total phosphoric are respectively 21.05% and 20.1%.4. The temperature has an influence on clean effect of the system, when the temperature descends from 20 °C to 10 °C, system clean rate of average COD descends from 87.1% to 52.4%. 5. Reactor VFA and PH measurement results express that the craft could circulate stably and efficiently.
