【摘要】 在生物除铁除锰技术指导下设计建造的沈阳经济技术开发区供水厂 ,是我国第一座成规模的典型的地下水生物除铁除锰水厂。它的工艺特点体现在跌水弱曝气 ,在同一生物滤层中除铁除锰及培养期、稳定期的反冲洗机制。生物滤层培养成熟后 ,滤池铁锰去除效率达 99%以上 ,出水水质优于国家标准 ,取得了稳定的运行效果。更多还原

【Abstract】 Shenyang economic development zone waterworks is the first large-scale biological underground water Fe/Mn removal facility in this country. By adopted cascade weak aeration all the functions related to Fe/Mn removal such as the microorganism culturing and maturing, steady filtering and backwashing are processed in the same filtering bed. When the microorganism maturing, a steady state stable Fe/Mn removal ratio excess 99% has been obtained, which is better than the requirement of the national standard.更多还原
