摘　　要：通过调查赤水河九仓—中华段各污染源,以化学需氧量(COD)和氨氮(NH3-N)为污染负荷指标,分析了赤水河九仓—中华段污染负荷现状,确定了主要污染源。在此基础上,选择NH3-N和COD为计算因子,利用一维水质模型测算出赤水河九仓—中华段水环境容量,COD:133.5 t/a,NH3-N:18.75 t/a。结果表明,各水平年COD和NH3-N都没有环境容量,主要是因为沿岸乡镇居民的生活污水未经处理直接排放,白酒企业废水也未达标排放。因此,必须加快各乡镇污水处理厂的建设并使污水达标排放;加强酒厂废水达标治理,确保国酒特殊水源的水质满足生产要求。Based on the investigation and analysis of various pollution sources ,status quo of Jiucang -zhong-hua section of Chishui River was analyzed with COD and NH 3 -N as index of pollution load ,and main pollu-tion source was determined.Choosing COD and NH3 -N as two indicators,water environmental capacity was computed using one dimensional water quality model as well .The water environmental capacity of COD and NH3 -N were 133.5 t/a and 18.75 t/a.The results showed that neither COD nor NH3 -N had environmen-tal capacity in each level year mainly because domestic sewage from the residents of the coast was directly discharged without treatment,and that treated wastewater of liquor enterprises did not meet the discharge standard.Therefore the construction of the town sewage treatment plants should be sped up to guarantee emis-sion standard,and the treatment of wastewater from the liquor enterprises should be strengthened to ensure the water quality to satisfy the special production requirements of national wine Maotai .
