Project summary

The aim of the project is to development of the combined technologies for wastewater treatment of “Sorbulak” accumulative reservoir of Almaty city.

The most perspective methods in this respect are the biological methods, as they do not lead to the secondary pollution, they have the high specificity and do not require the heavy capital investments.

The work efficiency of microbiologic (bacterial) specimens depends on the various reasons (local climatic conditions, character of organic pollutants, presence and quantity of local (indigenous) microorganisms’ forms).

Primary waste waters contain high concentrations of pathogenic and saprophytic flora that does not allow using bacterial preparations and so their preliminary treatment is required. It is reached by waste water precipitation in sequentially located accumulative reservoirs.

Now in the market there are many bacterial preparations for a treatment of environmental pollution, in particular from pollution by oil and oil products. However, these preparations ignore specific characteristics of pollutants, climatic conditions of object, presence and quantity of local (native) forms of microorganisms, therefore they are not effective. Native forms of microorganisms are most adapted to a survival, therefore development of a bacterial preparation will be made by a selection method of a native form of microorganisms having the greatest ability to utilization of organic pollutants of “Sorbulak” accumulative reservoir.

The radiation technology of silt activation for its further use as a nutrient solution for a buildup of microbiologic specimens will be used for the effectiveness increase of activity of microbiological preparations. The formation method of “activated sludge” is the preparatory radiation treatment, on the one hand, will allow to eliminate the competitive influence of others microorganisms strains, and, on the other hand, will allow to reduce a organic component density of silt, that will promote the improvement of organic compounds use by microbes.

Such technological approach will be tested on three sequentially located accumulative reservoirs that will allow determining on what of treatment stages of bacterial preparations use will give the maximal effect.

The spectrum of microflora (pathogenic and saprophytic) and contents of organic pollutants will be investigated in each of three sequentially located accumulative reservoirs. In the second and third accumulative reservoirs these indices will be investigated after use of a bacterial preparation.

The tasks of the project are:

  • research of an ecological situation of Sorbulak accumulative lake (bacterial flora and organic pollutants);
  • fermentation of resistant native forms of microorganisms in the polluted tests of silt and development of methods of increase of a developed preparation activity;
  • development of optimum regimens of microbiological cleansing of pollution from organic impurity of sediments of accumulative lake.

The staff of the Research Agricultural Institute will develop a bacterial preparation and the evaluation of its biochemical properties. The staff of the KNPU named after Abai will develop the species, time and dosage of a radiation treatment of silt. The staffs of the Research Agricultural Institute and the KNPU named after Abai will develop the selection of optimum associations of microorganisms and their environment conditions.

The participating institutes of the project have the qualified scientific personnel, experimental base and operational experience in the field of revegetation of organic origin pollutions.

The radiobiological technology of the wastewater treatment of Sorbulak accumulative lake will be developed as a result of project realization.

The scientists-participants of the project who previously were concerned in the development of a weapon of mass destruction, now will be involved in the solution of other problems – development the methods of revegetation from the pollutions of urban and industrial effluents.

Foreign collaborators may take part in discussion of the results of work and annual plans. We will also appreciate for their methodic assistance in this research.
