Novel wet-solid states serial anaerobic digestion process for enhancing methane recovery of aquatic plant biomass.

water plant biomass is characterized by a high water content and structure of lignocellulose. To apply digestion (AD) for the anaerobic treatment of aquatic plants, the simultaneous achievement of high methane (CH4) per volume of biomass recovery and high biodegradability has been a challenge because of these characteristics.

Here, we propose a new series of two-stage wet-and solid-state AD (SS-AD) systems are quickly digested fraction of labile cytoplasmic reactor AD first wet the retention time short while slowly digesting the fraction of lignocellulosic later SS-AD with retention time long. In this study, the effect of this series AD on CH4 recovery and chemical oxygen demand (COD) balance of aquatic plant biomass are examined in a semi-continuous operation. Elodea nuttallii, overgrowing in the valley south of Lake Biwa, Japan, was used as the substrate. For comparison, the different stages of AD with a hydraulic retention time (hrts) (30 d and 15 d) is performed.

The CH4 conversion efficiency at one stage AD deteriorated from 47.6 to 33.1% of COD with HRT is shortened, perhaps because of the low degradability fraction of slowly degrading (ie lignocellulose) in a short retention time. In contrast, AD series under the same HRT (15 d) as AD-one stage exhibited higher CH4 conversion efficiency of 65.1% COD, mainly due to increased degradation of the fraction of slowly degrading because prolonged solid retention time (52.2 d) of the entire system ,

The CH4 recovery from wet AD AD series alone systems surpassed that of 30 d-HRT from one stage of AD, probably because HRT is suitable for most small volatile and / or recirculation microbes. Serial wet and SS-AD suggested as a suitable technology for water treatment plant biomass with recalcitrant cell wall and cytoplasm unstable.
