动态水体修复模拟试验及自研菌剂应用研究

Study on dynamic simulation of water restoration and application of self-made bacterium agent

宜兴市前进河原水及底泥分别单独投加水体修复药剂、微生物菌剂及生物激活剂,通过实验室模拟动态水体修复实验研究对河流水体中污染物的去除效率。结果表明,硫酸铝/过氧碳酸钠对氨氮的去除效率最高,可达88.9%,生物活性剂对总氮去除最好,最高去除率为72.1%;复合菌剂适合于去除高锰酸盐指数,去除率可达70.4%;自研菌剂对氨氮、总磷及高锰酸盐指数的去除率明显高于外购菌剂,可作为新型水体修复菌剂使用。

In order to determine the removal efficiency of water restoration Pharmacy and microbial agents on river pollutants,through a laboratory tests to simulate the dynamic water restoration,the water and sediment comes from Qianjing river in Yixing city. The results indicate that,the removal efficiency of aluminum sulfate/sodium carbonate peroxide to ammonia nitrogen is highest,can amount to 88. 9%,the biological active agent to the total nitrogen removal is best,the highest removal rate was 72. 1%,and the compound bacterium agent is suitable for removal of permanganate index,removal rate of 70. 4%,the removal rate of self-made bacterium agent to ammonia nitrogen,total phosphorus and permanganate index was obviously higher than that of outsourcing bacterium agent,it can be used as a new type of water body repair bacteria agent and promotion.
