Abstract

The invention relates to an ecological combined device for treating sewage with high ammonia-nitrogen content. The ecological combined device comprises a multifunctional regulation pool, a deodorizing device, an internal-electrolysis anaerobic/anoxic organism iron-carbon reaction pool, a flexible biomembrane contact oxidation filter pool, an air blower room, a sedimentation tank and constructed wetlands. According to the ecological combined device disclosed by the invention, organic pollutants, nitrogen/phosphorus pollutants and animal/vegetable oils and fats are efficiently removed from wastewater through integrating hydrolysis, microelectrolysis and the biochemical reaction of iron bacteria, anaerobic bacteria, facultative bacteria and the like and combining a physical/chemical adsorptive precipitation-percolation process and a plant absorption and transformation process. The ecological combined device can be widely applied to a high-concentration organic wastewater and reclaimed water recycling system and a regenerated water recycling landscape water system, and has the characteristics of stability, reliability, low investment, low operating energy consumption, low operating cost, easiness in maintenance and management, and the like.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to an ecological combination device for treating ammonia nitrogen sewage. Background technique [0002] With the growth of population and economic development, the demand for fresh water resources is increasing; at the same time, due to irrational use, the shortage of fresh water resources is becoming increasingly tense. Reuse of reclaimed water is one of the main ways to utilize sewage water resources. In the 1950s and 1960s, European and American countries had begun to recycle sewage. Compared with foreign countries, my country's urban sewage reuse technology started relatively late, but it has developed rapidly in the past 10 years, and the starting point is relatively high. Water-scarce cities such as Beijing, Tianjin, Taiyuan, Qingdao, and Xi'an have successively established a series of sewage reuse projects. However, due to financial and technical reasons, my coun...
