Technology for conversion of whey into organic-mineral fertilizers with amino acids

N. Terentyev Yu., V. Syrchina N., , V. Sazanov А., L. Sazanova M., A. Kozvonin V. &
Rational processing of whey is one of the most important problems of the dairy industry. Less than 50% of this waste is processed in Russia. Unprocessed whey is discharged into the sewage systems, which significantly increases the degree of contamination of the process waste water. Basically, processing of whey in commodity products is limited by economic factors. At the enterprises of small and average capacity high costs of introducing processing technologies do not pay off...

Reliability of sanitary and epidemiologic analysis of sewage at a large number of casual impacts and absence the dominating factor

It is known that the existing methods of the analysis of sewage composition can reveal excess of maximum permissible concentration no more than ten percent of total of rated pollution. Therefore, the actual task is increase of reliability of sanitary and epidemiologic analysis of sewage and cleaning quality of industrial drains as for existence of traces of pollution. It is reached by accounting of probabilistic and time characteristics of a stream of pollution receipt at...

Plant-microbe associations of the non-traditional sugar plants and the producers of natural sweeteners

, &
Soil microbial succession in chernozem under the influence of rhizodeposites of different groups of plants-sweeteners was investigated. It is found out that non-traditional sugar plants (Helianthus tuberosus, Smallanthus sonchifolius, Cyperus esculentus) enhance mineralization processes and reduce nitrogen immobilization, while producers of sweet glycosides (Stevia rebaudiana, Glycyrrhiza glаbra) do not change the trophic structure of soil microbial society. The species structure of microbial society was studied by the example of a complex of micromycetes. The general...

Benz[a]pyrene destruction by Elodea canadensis L. in water

The simulating model experiment on water-dissolved benz[a]pyrene (BP) impact on composition of polyarenes in Elodea canadensis L. plants was conducted. For that, five concentrations of BP in water solution were used: 1; 5; 10; 20 nanogram/l. To the end of the experiment, BP was found in water only when introduced in dose of 20 nanogram/l. We identified other PAHs in solution which could be BP destruction products made by Elodea Canadensis L. cell sap. Total...

Profile distribution and composition of some soil organic matter components at peatlands was studied. The humus state parameters which are accessed on base of fraction-group humus composition data are good markers of formation conditions of active...

Amphiphilic properties of soil organic matter in parcels of dominating coniferous trees in the middle taiga zone

The paper deals with morphological structure, physical-chemical and amphiphilic properties of soil organic matter in parcels of dominating tree species in the middle taiga zone of the Komi Republic. The study soils have similar morpho- logic structure, physical-chemical properties and profile distribution of amphiphilic fractions. The majority of migrating organic compounds accumulate in lower organic sub-horizons. Distribution of fractions in upper mineral sub-horizons depends on texture (granulometric composition) of soil-forming rocks. Profile distribution of hydrophilous...

Morphogenetic structure of marsh frog populations of Pelophylax ridibundus (Amphibia, Anura) under conditions of urban environment

E.A. Snegin & A.S. Barkhatov
On the basis of morphometric, phenetic and molecular genetic methods, the population structure of the Pelophylax ridibundus inhabiting the urbanized environment of Belgorod and its environs (Russia) was studied. The obtained results confirmed the previously stated assumptions, according to which under the conditions of anthropogenic load the color morph “striata” dominates (the proportion of individuals on impact territories was 70 to 93%). In relatively pure biotopes, the color morph “maculate” prevailed (58–67%). The morphometric characteristics...

I.A. Zyryanov, A.P. Pozolotin, A.G. Budin & E.V. Kantor
Electric power generation based on combustion of organic fuel is one of the largest sources of air pollution by toxic substances, including products of incomplete combustion. To reduce the negative impact of power plants on the environment, various methods are used to optimize the regimes for burning fuel and cleaning the emissions of combustion products into the atmosphere. One of the promising ways to regulate the combustion of fuels in order to reduce emissions is...
