Rural Drinking Water Safety Of Shandong Provice-Application Of Special Water Quality Treatment Technology And Post-establishing Management Of Rural Drinking Water Safety Project

In recent years, the difficult job of drinking water in rural areas has made great progress. However, the situation of drinking water safety is still very flinty. The drinking water in some areas exist some questions of severe water pollution, low guarantee rate of water supply, water-borne endemic. In particular, the water quality problems, such as high-fluorine, high arsenic, brackish water, polluted water and schistosoma, seriously endanger the health of rural residents.After investigate and study the status of rural drinking water safety of Shandong provice, we can see special water quality are very prominent in the problems of rural drinking water safety of Shandong Province. Therefore, the problem of special water quality became a key to solve the problems of rural drinking water safety in Shandong province. At the same time, the post-establishing management of rural drinking water safety project is the important guarantee for the normal operation of rural drinking water safety project. Therefore, the study of the post-establishing management is very urgent and necessary.This paper collect the primary trentment methods of brackish water desalination and fluoride removal, fully compare their respective advantages and disadvantages, And according to the characteristics of rural areas in Shandong Province, choose the trentment methods basing on principles of low-cost, simple and stable operation, simple equipment. Finally, the paper choose reverse osmosis process to desalinate the brackish water, design the reverse osmosis system for a typical example, and use Dow's design software FILMTEC ROSA to predict water quality, which can achieved even better than the national hygiene standards for drinking water. The paper choose activated alumina adsorption method removal fluoride, because the method has mature technology and been widely used, this paper only describe its technology and equipment. At the same time, in view of rural drinking water safety project generally pay attention to construction and scorn management, analyze the main problems of the current post-establishing management of rural drinking water safety project, and summed up the mode of the post-establishing management of rural drinking water safety project and the problems which are should be paied attention to. Through the results of this paper, on the one hand, rich the theory of rural drinking water safety, on the other hand, provide the reference and theoretical basis for the treatment of special water quality of the rural drinking water safety in Shandong Province and the post-establishing management of rural drinking water safety project.
