Abstract


Purposes:Turpan region centralized rural drinking water safety project monitoring points for water quality survey, puts forward Suggestions and opinions for the work of the regional water quality monitoring and water treatment, and to provide a scientific basis for the Government to formulate a reform water policy.Methods:According to the distribution of drinking water safety project, select the Turpan area, Turpan City, Toksun County, Shanshan County three counties (cities) as a water quality monitoring points. Monitoring indicators include sensory properties and chemical indicators, toxicology indicators, microbial indicators and disinfectants conventional indicators. Water sample collection, preservation, transportation, testing, analysis and evaluation of results are the requirements in accordance with the drinking water standard test method (GB/T5750-2006). Compare indicators for monitoring of the water samples of the finished water and peripheral water in the dry season and the wet period, as well as different water types.Results:A total of109water quality project monitoring point218to detect various types of water quality, detected a total of4,142times, finished water pipe network peripheral water, water from deep wells and springs pass rate of76%,73%,73%,76%; the factory with peripheral water toxicology indicators pass rate were100%, the total number of colonies in the sensory properties of microbial indicators and general chemical indicators, total coliform bacteria, heat-resistant coliform, chlorides, sulfates, solubility total solids, total hardness have substandard water samples, and other indicators pass rate of100%; finished water of the dry season and the wet period, peripheral water, spring water, water from deep well water sample pass rate difference. One sample of excess fluorine occurred in peripheral water samples in the dry season。Conclusion:Turpan region rural life drinking water quality get to improve, the state’s policy support to provide an important safeguard; The existing problem is microbial index to exceed bid, water supply facilities misgovernment. And earnestly do good jobs in rural water supply planning, strengthen the rural drinking water safety engineering operation management, strengthen rural water conservation, strengthen water management, and constantly explore suitable for rural drinking water treatment process, will help promote the development of rural water supply, and improving the rural drinking water quality.
