摘要
北方特大缺水城市景观河道由于水资源短缺,河道用水置换次数少,河道水体自净能力低等原因,水体富营养化现象严重。采用新型除磷药剂——锁磷剂和微生物菌剂复合技术对河道水体进行水质净化试验。通过考察复合菌剂脱氮和降低COD的效果,来确定适宜的微生物投加浓度和验证复合技术的使用方式。
Because of water shortage, few replacement times of water in river, low self-purification capacity, the landscape rivers in water shortage megalopolis of northern China have serious entrophia problems. The channel water purification experiment was done by using composite technology of phoslock-microbial agents. According to the test of purification effect of complex bacteria on nitrogen and COD removal, the suitable concentration of complex bacteria was determine and the suitable using way of composite technology was confirmed.
