1. Tashkent Medical Academy Chair: Communal Hygiene On the topic: «Sanitary protection of reservoirs».

2. The purpose of the activity: To familiarize students with the hygienic assessment of the health situation in the address of sanitary protection of water bodies of administrative territories. To familiarize with the hygienic assessment of pollution of water bodies used for drinking and amenities nuzh population. Train organizations laboratory control over the quality of water in water bodies administrative territory To introduce sanitary examination procedure of industrial object, including objects of agricultural, housing and civil purposes, which are sources of pollution of surface waters SPE stage. To familiarize with the hygienic assessment of the sources of water pollution on stage PSS.

3. The student should know: Operating principles of the possibility of protection of surface water from sewage pollution Features of the organization and conduct of sanitary and epidemiological measures to mitigate the adverse effects of risk factors on health and the environment. Give an opinion on the basis of descent SanPiN 0056-96 waste water into the pond Organization and carrying out sanitary and epidemiological measures for the protection of surface water Conduct sanitary inspection of supervision and make appropriate accounting and reporting documentation of the quality of the reservoir study. Rules of sampling, transport and storage of samples taken, the accompanying drawing blanks.

4. The student should be able to: Conduct sanitary inspection of supervision and make appropriate accounting and reporting documentation under the control of objects. Carry CSS for the Protection of open water. Carry on CSS station wastewater treatment and assessment of the effectiveness of cleaning. Perform visual, laboratory instrumentation, calculation methods define the conditions of water discharge into water bodies. Preparation of graphic diagrams indicating the sampling points of water open water. Interpretation of the results of laboratory and instrumental investigations

5. motivation Participation sanitary physician assessment open water from sewage pollution to assess the quality of open water. To determine the conditions of descent of sewage and to develop methods for effective cleaning. Create health conclusions about the effectiveness of mechanical, biological methods and disinfection of wastewater.

7. Water pollution:Water quality characterized by the following parameters:1) Naturala. The physical temperature, color, material etc. vzveschennye2) Biological: microorganisms, bacteria, viruses, protozoa, etc. 3) Chemical: inorganic substances (salts of the acids, heavy metals), organic contaminants (pesticides, hydrocarbons)

8. I. In its origin impurities in water consumption are divided as follows: a) due to the influence of cities and populated areas: domestic waste water, storm water, waste dumps. b) due to the influence of industrial activity: a violation of the integrity of the soil (quarrying, drilling, wiring mines, toxic solid and liquid waste, industrial process water, (sugar, pulp and paper industry), storage of materials, waste disposal, soil contamination air emissions (acid rain, heavy metals) and their infiltration). c) due to the influence of agri - business activities: soil contamination with agrochemicals (fertilizers, plant protection products), animal production waste (slaughterhouse myasopererabotyvayuschie enterprise).

9. II. Distribution of contamination over time. A) by means of a continuous leaching of contaminants from improperly landfilled or disposed waste and their infiltration into aquifers. B) season in periods of intensive use of agrochemicals, the use of chemical means of protection, water pollution flanged water С) accidental: accidents and sewerage pipelines, technological pipelines and routes of transportation of chemical substances, emergency spill the contents of rail tank cars and tank trucks,

10. III. distribution in space: A) expanded in areas used for agricultural activities. B) that is located at industrial sites, landfill sites and waste disposal, due to the influence of the urban environment (city, town) B) linear: along highways, railroad tracks, rivers.

11. Work on control of hygiene practices in the implementation of measures aimed at preventing water pollution are carried out in the form of PSN and TSN PSN includes: 1. Consideration and approval of projects of construction, reconstruction or expansion of sewage of settlements and other objects of waste water that may be a source of contamination of surface waters. 2. The determination of conditions of descent of sewage into the reservoir, ie the required degree of purification. 3. sanitary supervision during construction and sewage treatment facilities, participation in the acceptance of their operation.

12. New pedagogical technologies used in class The method of "Handle in the middle of the table." It is proposed to specify the group. Each student writes on a piece of one answer and sends it to the next, and my pen moves to the middle of the table. This method can be used in written and oral form, with no use of job training and monitoring programs. Common answers the student is evaluated on the point system. Each question is given 15 minutes.

13. The method of "Round Table" Divide the group into small groups of 2-3 people, each MG offer sheet with the issue and ask for 1-2 minutes, write the answer to the question, and then pass another piece of MG and MG to take from another the next question and so on So, if organized 5 mg (2 students per table 1), the teacher hands out 5 questions and eventually on each piece should be 5 replies. After 12 minutes, the teacher collects all sheets and analyzes the quality of the answers aloud and exposes the evaluation of each MG.

14. Control questions: Sources of water pollution Relatively hygienic characteristics of domestic and industrial wastewater. Facilities used mechanical cleaning wastewater.Circular tanks, the principle of the settler. Septic and double decker settlers, application devices. The process of biological treatment.
