Shandong A Military Barracks In Sewage Treatment And Water Reuse Technologies

With China's rapid social and economic development, environmental issues become increasingly prominent, especially in the deterioration of water environment exacerbated the shortage of water resources. Military environmental protection as part of the national environmental protection, military barracks, and sewage treatment is imminent.In this paper, on the basis of the relevant literature, reviewed the current situation and control of water pollution, and analyzed the current situation of water pollution and pollution-scale forces, characteristics. In accordance with the requirements of eco-camp construction, not connected to municipal sewage pipe network of the camp should build an independent small sewage treatment station after the sewage treatment reuse. For example, the issue of a military camp in Shandong, selected technology and methods for the camp sewage treatment and reuse, designed of the sewage treatment project; sewage treatment works commissioning and operation management of the camp.Shandong, a camp located in the Bohai region, is a national key pollution control areas. Camp located in the suburbs, there is no municipal pipe network. Sewage is directly emitted into the outside rivers of the camp through the sewage ditch without treatment. The discharge standards of the basin are strict. Local government has repeatedly requested it for treatment. Resident camp is one of the cities of key water shortage. So the camp sewage should control and reuse. Under the specific circumstances of the camp, combined with ecological requirements of the camp, the hydrolytic acidification-biological contact oxidation technology should be improved. Using buried Sewage treatment one integrated tank design as its sewage treatment, and greening the environment. Process is simple and practical, mature and reliable, stable operation, low investment, simple operation, low cost.Sewage treatment camp about 300 t/d, chemical oxygen demand in water of about 400mg/L, biochemical oxygen demand of about 200 mg/L, ammonia about 40 mg/L. total nitrogen of about 50 mg/L, TP of about 5 mg/L. After three months of trial operation after commissioning, the effluent CODcr redused less than 50 mg/L. Biochemical oxygen demand is less than 10 mg/L. Ammonia is less than 5 mg/L. Total nitrogen is less than 15 mg/L. TP is less than 0.5 mg/L. These indicators meet the "urban recycling water for landscape and environmental quality (GB/T18921-2002) standards. Resuse sewage for watering flowers and trees, add water and washing the park landscape, not only solve the sewage straight row of environmental problems, but also save fresh water, reduce costs, meet the ecological requirements of the building barracks.
