| description | The accumulation of solid and liquid organic waste requires their treatment to develop energy biotechnologies and prevent environment pollution.
Aim. The goal of the work was to study the efficiency of the purification of the filtrate from dissolved organic compounds by aerobic oxidation and methane fermentation.
Methods. The standard methods were used to determine рН and redox potential (Eh), the gas composition, the content of short-chain fatty acids, the concentration of dissolved organic compounds counting to the total сarbon. The efficiency of two types of microbial metabolism for the degradation of soluble organic compounds of filtrate was compared.
Results. The aerobic oxidation was established to provide 1.9 times more efficient removal of dissolved organic compounds, compared with the anaerobic methane fermentation. However, it provided CH4 yield 1 L/dm3 of filtrate (сarbon concentration — 1071 mg/L). The necessity to optimize the methods for purifying filtrate to increase the efficiency of the process was determined.
Conclusions. The obtained results will be the basis to develop complex biotechnology providing not only the production of environmentally friendly energy H2 via the fermentation of solid food waste, but also the purification of filtrate to solve the ecological and energy (CH4 production) problem of society. |
