COMBINED STATION BIOLOGICAL WASTEWATER TREATMENT WITH THE USE OF

RENEWABLE ENERGY.

Abstract: The article discusses the technology of sewage treatment with the production of biogas from the higher water plants - Eichhorn, which allows to solve complex environmental, food and energy problems.

Keywords: higher aquatic plants, combined waste water treatmen technology, green mass Eichhorn, air de-odorization.

Bioenergy is a promising direction of AEI, since it does not depend on climatic conditions and continuous, it can be produced directly if necessary consumption. Stations of purification of urban sewage of the Republic of Uzbekistan are working on the principle of biological purification of waste water by aerobic microorganisms. According to the technology, with vigorous bubbling air and multiple circulation, waste water under the action of aerobic microorganisms cleaned and disinfected.

At the Biological Station of treatment of urban sewage Andijan studies have been conducted to determine the effectiveness of the use of higher water plants eyhorniya in the combined wastewater treatment technology. Table-1 shows the results of the analysis of wastewater, carried out the Andijan Oblast SES before planting the plants and the dynamics of sewage treatment at intervals of 24 hours [1]. Bacteriological laboratory Andijan Regional CSES.

The laboratory apparatus 1 kg. green mass Eichhorn, was received on average 14 liters of biogas per day for 30 days, at a temperature of 36 0C. Calculations show that the number of biogas processing green mass Eichhorn 1 hectare bio-ponds can be more than 500 000 m3 per year. Given that the methane content in biogas by an average of 63 %, the number of equivalent calorific value of natural gas capacity will be up to 400,000

m3. Since the estimated water surface treatment plant required for the processing of incoming sewage is 20 hectares, the number of biogas production could reach more than 1 million m3 / year.

Thus, on the basis of the research, we can conclude the feasibility of using Eichhorn in the combined treatment technology of wastewater of industrial and household objects for various purposes, and other waters,

which differ in the degree and nature of contamination, thus find their comprehensive solution to the problem of ecological, agricultural (food) and energy areas:

- Cleaning and disinfection of wastewater and air deodorization biological treatment plant and the surrounding areas;

- Receiving a significant amount of biomass with a high content of protein, from which you can get protein-vitamin feed additive and organic fertilizer (ver-micompost);

- Green mass Eichhorn is an effective raw materials for alternative energy sources - biogas with high calorific value, which can be used in a cogeneration plant to produce electricity and heat.

Additional water treatment effects using Eichhorn is, firstly, the reduction of the number of working production lines and compressor plants, and secondly, you can dispense with the chlorination of water, which results in a double positive effect: improved health and safety of staff and reduced admission to the surrounding condition dangerous organochlorine compounds and chlorine.

THE SUBSYSTEM OF SEARCH IN THE DISTRIBUTED INFORMATION SYSTEMS

Summary. The article describes the principles of the search subsystems of the distributed information systems. It describes the basic mechanisms of the search engine, here the modern search engines of the world, and their positive and negative traits are revealed; it is determined that a successful search is associated with the use of search algorithms, synonyms and synonyms thesaurus.

Key words: search, information, network, distributed information systems, resource, Internet.

Introduction. Due to the rapid development of the mation systems was the subject of many scientists' re-

telecommunications technology and Internet, in particular, the problem of effective information search development is getting an extreme topicality. The distributed systems exist in various forms and store information by many different methods. The information search in such systems is currently the subject of the scientific debate and research, because if the information can not be found, information is defined as lost.

The interest to the issue of searching for the information was not weakened during the network lifetime. While carrying out information search that satisfies the user's information needs, it is necessary to know, what determines a successful search and which problems arise when working with the information.

In this article the existing search engines are examined, their advantages and disadvantages are analyzed and the solutions are offered which provide the high efficiency of information search in the distributed information systems.

Analysis of the recent research and publications. The subsystem of search in the distributed infor-

search, in particular such as A. Trusov [4], V. Trusov [4], T. Atanasova [1], B. Voyskunskii [3], A. Barysheva [2] and others.

Setting objectives. To analyze the mechanisms and principles of the subsystems of information search in the distributed information systems. To explore the algorithms of subsystem information search in distributed information systems of Internet. To describe the major search engines, identify their positive and negative traits.

The material presentation. The engine of information search in the distributed information systems takes one of the leading positions in the information system and system efficiency depends on its realization. At the same time, the realization of the extensive search capabilities may negatively affect the system productivity. [3].

Three basic requirements are provided to the search engine:

- the control of coverage resources;

- the control of accuracy of information received from the network;
