摘要
选取炉渣、陶粒、锯末3种填料,建立植物-微生物组合式人工沉床,在室内条件下,研究不同填料下的植物-微生物组合式人工沉床对轻度污染水体中高锰酸盐指数(COD)、总磷(TP)、氨氮(NH+4-N)及硝酸盐(NO-3-N)的去除效果。结果表明,炉渣、锯末填料的植物-微生物组合式人工沉床对轻度污染水体修复效果较好,但锯末填料在试验后期(15~18 d)出现腐烂、去除率下降等问题,因此炉渣可以作为植物-微生物组合式人工沉床的理想填料。
Select slag,ceramic and sawdust were selected as fillers to establish combined artificial microbes submerged bed under laboratory conditions to study the removal effect of COD,total phosphorus( TP),ammonia( NH+4-N) and nitrate( NO-3-N) under different treatment conditions. The results showed that slag,sawdust pack have better treatment effects for light polluted water bodies,but sawdust filler is easy to rot and have lower removal rates due to other issues in the latter stage of tests( 15 ~ 18d). So slag can be used as an ideal filler for composite artificial microbes submerged bed.
