Opis:
The paper summarizes the results from twenty model tests of continuous one-stage mesophilic anaerobic co-digestion of cattle slurry (90 wt. %) and various biowastes (10 wt. %). Digestion was conducted in 0.06 m3 reactors with hydraulic retention times ranging from 60 to 98 days during the research period 2007-2010. Methane production intensity and specific methane production are discussed. The highest methane production intensity (0.85 mN3.m-3.d-1) was from a mixture of 63 wt. % of total solids from biscuit meal EKPO - EB and from 37 wt. % of total solids from cattle slurry. The highest specific methane production from 1 kg of added organic compounds (0.67 mN3.kgVSp-1) was given by a mixture containing 61 wt. % of total solids using spring barley Aksamit (milled grain) and 39 wt. % of total solids from cattle slurry. The highest substrate-specific methane production (0.92 mN3.kgVSp-1) was from milled grains of winter rye Aventino.

Opis:
A laboratory physical model of a new type of anaerobic fermenter for “dry” and “wet” anaerobic digestion consisting of silage bags was designed. In the model, the experiment based on high-solids discontinuous anaerobic co-fermentation of agricultural substrates was carried out. It was verified that a horizontal fermenter constructed from silage bags is a suitable type of equipment for the production of biogas. The biogas production peaked at 4th day and was completed by 18th day. Within 18 days of discontinuous high-solids process (18.5-20.0 wt. %TS) the intensity of biogas production reached 1.18 mN3. m-3 . d-1, or 0.0012 mN3. kg-1 . d-1, and the specific methane production 0.01 mN3. kg-1, or 0.07 mN3. kgVS-1. After conversion of the modeling process to a semi-continuous low-solids mode (3.5-5. 5 wt. %TS) during the daily dosage of 87 wt % mixture of biscuit meal EKPO-EB with 13 wt % CaO, the intensity of biogas production reached the value 2.42 mN3 . m-3 . d-1, or 0.0105 mN3 . kg-1 . d-1. The fermentation bag appears to be a more efficient device in the semi-continuous “low-solids” Laboratory model: “(2 inches)”.

Opis:
The aim of this paper is a mathematical description of algorithm for controlled assembly of incinerated batch of waste. The basis for formation of batch is selected parameters of incinerated waste as its calorific value or content of pollutants or the combination of both. The numerical model will allow, based on selected criteria, to compile batch of wastes which continuously follows the previous batch, which is a prerequisite for optimized operation of incinerator. The model was prepared as for waste storage in containers, as well as for waste storage in continuously refilled boxes. The mathematical model was developed into the computer program and its functionality was verified either by practical measurements or by numerical simulations. The proposed model can be used in incinerators for hazardous and municipal waste.
