| Tartalmi kivonat: | Mushroom growing is a sector of the national horticulture and the compost production is an essential part of the technology. The mushroom compost production is an environmental activity, because there is an opportunity in economical processing of big quantity of agricultural by-products. The mushroom compost contains chicken manure, straw, peat, yielded mushroom residue (residual stump, mycelium, mushroom) and sometimes horse manure. During the technology the quantity of ammonia emitted by the firms and the odour emission and the stench contamination is a serious problem. The large-scale manure production modelling of biogas experiments used liquid pig slurry as raw material. The additives were bran, mushroom compost and maize silage. The industrial by-products and wastes suitable for biogas production are defined by the dry matter, organic matter, nitrogen content, C:N ratio, specific gas yield. The intensity of the methane production is the direct measure of the activity of the methanogenic bacteria, and the most sensitive, typical indicator of the digester's yield. The combination and the yield of the produced gas features may be useful to estimate the stability of the anaerobic system. Consequently, the results of the examinations bring practical profit on the sizing, investment and firm operational area indispensable. |
