| Drinking water sources protection has become a common concern of the world’s topic, many scholars at home and abroad from the city water source of drinking water safety evaluation, the division of drinking water sources protection zones for water source protection present situation, problems and countermeasures, and water source protection legislation experience and so on different angles on the in-depth research.Work on current international, the protection of water source is becoming more and more attention, the United Nations educational, scientific and cultural organization has reduced the water source protection related topics included in the international hydrological phase 6 focus on. Liuhe as jilin province new regional economic center,agriculture and agricultural product processing industry has developed rapidly,industrial parks and the rapid development of private economy, more and more is also high to the requirement of urban infrastructure.The current supply and demand of water in the basic balance state. But with the constant improvement of the economic development, people’s living standard and the liuhe county economic development zone of large-scale construction, water resources shortage, water pollution, water quality deterioration ha yu economic sustainable development faces three big bottleneck, "water" to people’s health and production life impact.As a result, in this paper, a new water source of large forced child reservoir as the research object, the "basic information collection, analysis of domestic and foreign research now,evaluation of water quality status of status quo survey carried out for the water-source survey, reasonable division of reserve, put forward countermeasures for water source protection" route for research.According to the forced child station monitoring water quality value and single index evaluation results show that the forced child categories for Ⅲ throughout the year, water quality standard project for the permanganate index and chemical oxygen demand(cod), 5 biochemical oxygen demand(cod), ammonia nitrogen, which is8.3%.According to survey data show that water supply and consumption, urban water shortage, respectively in 2020 and 2030, 695.9×104m3,1008×104m3and Ann county in 2020 and 2030 water were 142.4 × 104m3and219.0 × 104m3.According to the pollution source survey, forced child reservoir water source of drinking water pollution wource sources pollution is mainly distributed in rural life, farmland runoff pollution, decentralized four categories of livestock and poultry breeding pollution and other pollution.On evaluation, present situation of water quality for water status quo and pollution source survey, on the basis of the experience analogy method is adopted reasonable division of forced child reservoir level reserve, secondary reserves and prospective reserves.Liuhe forced child reservoir level reserve covers an area of 8.82Km2, accounting for 2.6% of the catchment area(338 Km2). The secondary reserve covers an area of 53.83 Km2, accounting for 15.9% of the catchment area(338 Km2).Prospective reserve covers an area of 275.35 Km2, accounting for 81.5% of the catchment area(338 Km2).Finally, according to the regulation on administration of prevention and control of pollution of drinking water sources reserve, the jilin province urban drinking water sources protection ordinance, from the legislation protection, policy measures,comprehensive control, strengthening the supervision, perfecting the monitoring five aspects give me some Suggestions on strengthening prevention and control of water pollution and protection, for the liuhe county departments concerned shall strengthen the supervision of water source and ensure the safety of water quality to provide the reference basis. |
