Microbiological characteristics of municipal solid waste in St. Petersburg

The article is devoted to the problems of housing-and- communal services in the cities of Russia and their development in modern conditions. The research purpose was to give the theoretical justification as well as to develop some methodical recommendations on formation and implementation of the programmes of complex development of housing- and-communal services in the municipal units. The authors systematized the typical properties and specifics of housing-and-communal utilities, the role of the sector in preserving the environment, revealed the factors complicating their development significantly, carried out the analysis of the housing-and-communal sector condition and the sector’s needs for investments. According to the analysis results, the authors prove that modernization and improvement of housing-and-communal sector demands drawing up target programmes of complex development. In article Principles and stages of the development of the programmes of the improvement of the housing-and-communal utilities were offered, the directions, considered to be the most relevant, were pointed out. The authors recognize such consequence of the housing-and-communal utilities modernization as the increase of the utility tariffs and the need of assessment of the availability of housing-and-communal services for consumers. The authors offer the new indicator, namely, the share of the provided subsidies in the total amount of payments for premises and utilities, for the improvement of such assessment. The results of the research can be used by the practicians, forming target municipal development programmes of housing-and-public utilities development within the general strategies of the cities and regions development, aimed at the improvement of the population life quality and at the decrease in the environmental risks.

“…In addition to sand enrichment, the method can be successfully used for disinfection of liquid and solid waste [4]. Sand similar in consistency, very significant (from 5-10 [5, 6] to 20-34% [7,8]) and problematic (moisture ≈80% wt., Microbiological contamination 109-1010 CFU / g [9]) fraction of the municipal solid waste can be successfully sanitized in the same way.…”

The paper presents the results of research on the use of a pulsed electric discharge in aqueous media for the pretreatment (preliminary crushing and washing) of quartz sand in the glass industry. The averaged granulometric and elemental composition of quartz sands of the Muraevnya deposit has been studied (explored reserves are 31 million tons). The efficiency of the proposed method for treating quartz sand for its subsequent cleaning from undesirable impurities (primarily iron and clay oxides) is shown, preliminary parameters of the treatment process, changes in the granulometric and elemental composition of raw materials, and specific energy consumption for its treatment are determined. The main advantage of the technology is that it makes it possible to obtain such a degree of purification of quartz sand from impurities due to the destruction of impurities aggregated with silicon oxide particles, which is unattainable with standard flushing.

A multicenter study of the application of the microbiological preparation Embiko® in vineyards with its introduction with drip irrigation in the Western foothill-seaside viticultural zone of Crimea was carried out. Granulometric analysis of the soil showed that in the experimental version with the use of Embiko®, the specific content of its fine fractions increased by 5%, i.e. the soil became looser. The introduction of Embico® in liquid form with drip irrigation gave an increase in yield by 1.3 kg per bush, while the sugar content of the berry juice improved by at least 8%. An antistress effect on plants under the influence of treatment with a biological preparation was also revealed, which manifests itself in a significant functional improvement of the leaf apparatus and an increase in the growth rates of grape shoots. When using the biological preparation Embico®, the profit or net income at the pilot site increased compared with the control option (without application) and, accordingly, the profitability of production increased by 79%.
