摘要:
本文对辽河12个断面和大辽河3个断面的水质参数:pH、溶解氧、COD、BOD5、氨氮和总磷的空间变化进行了研究。结果表明,辽河和大辽河流域15个监测断面水体的pH值都大于7;辽河上游到下游COD、BOD5呈上升的趋势,大辽河3个断面都达到劣Ⅴ类;监测断面中有接近70% 断面总磷,80%断面氨氮都达到劣Ⅴ类;辽河和大辽河的污染非常严重。


Abstract:
Space variation of water quantity parameters including pH、DO、COD、BOD5、ammonia nitrogen and total phosphorous were investigated in 12 sections of Liao River and 3 sections of Daliao River. The results showed that pH values in 15 sections were above 7. The trends of COD and BOD5 from upstream to downstream in LiaoRiverwere gradually increased. The values of COD and BOD5 in 3 sections of Daliao River reached interior V class. The values of ammonia nitrogen about 70% of all sections and total phosphorous about 80% reached interior V class.LiaoRiverandDaliaoRiverwere seriously polluted.
