A dynamical model of intensification of the recycling process of liquid manure in a methane tank with an anaerobic bio-filter

The main ways to intensify anaerobic processing of liquid manure is to increase an active bio-mass in a methane tank. A dynamic functional model of a methane tank with an anaerobic bio-filter is introduced in the article. As the initial sources of the model, the Conto and Mono models were used. The mathematical essence of the dynamic model is the immobilization of the methanogenic microflora on the carrier (kapron cord) of the bio-filter, which is characterized by the rate of gas generation from a unit of fermented raw materials. In accordance with the dynamic model, a structural model of anaerobic processing of liquid pig manure in the methane tank was developed. The model was based on the criteria for assessing immobilisation properties and physic-structural characteristics of bio-filter carriers. The developed dynamic model will make it possible to intensify the process of anaerobic recycling of organic sewage of livestock. The productivity of the bio-filter functionally depends on the structural elements (the number of blades, diameter and length of the cord), with increase in size of which the area of methanogenic microflora and the rate of gas formation increase.
