Study On The Process Design For The Mutual Sewage Treatment And Recycling Technology In Hulun Buir

Now, with the implementation of the strategy of eastward expansion of Hulun Buir City, settled enterprises isgrowing, and the sewage is increased dramatically. Since there is no sewage treatment works in the area, it has seriously restricted the economic and social development. On the one hand, water shortages have become increasingly prominent; on the other hand, the increasing amount of waste water discharge, and realize the wastewater recycling is the best choice to solve the contradictions, the recycling of sewage treatment plant sewage is the effective ways to increase income and reduce expenditure tap new sources of supply and reduce consumption in the eastern section of Hulun Buir City, reduce water pollution, improve the ecological environment and solve development zone water shortage, it is necessary to build sewage treatment and recycling engineering in the eastern section of Hulun Buir City.Sewage treatment process of this engineering combined with the discharge sewage water quality characteristics of the eastern section of Hulun Buir City, the wastewater treatment scale of the proposedwastewater treatment plant was designed as 40,000m3/d and 100,000m3/d for recent and long-term, respectively, and through schemes comparison, using " hydrolysis acidification tank+A2O biochemical tank+Four-phase advanced oxidation processes+Flocculation reaction precipitation + filter ".In addition, level A standard of “pollutant discharge standard of urban sewage treatment plant”(GB18918- 2002) of effluent quality would be achieved.After this project is completed, the eastern section of Hulun Buir City formed perfect sewage system, the sewage will be timely and effective treatment, and form a complete regeneration water recyling system, protect the hailaer river basin and water quality, reduce the public health event, so as to improve the level of public health. Technology and the effect of the whole engineering will achieve the domestic leading level, can improve the comprehensive utilization of water resources, can play a good role in environmental protection.
