长江武汉段工业港酚污染带研究

Study on phenolic contaminated zone of the Changjiang River in Wuhan

建立了计算污染带长度、最大宽度及其出现距离的解析模式和给定污染带范围下排污口允许排污量的简便算法。对长江武汉段工业港酚污染带作了应用研究。结果表明，到２０００年该污染带长、宽将分别达到４３５７．９ｍ和４７．１ｍ，最大污染带宽出现在排污口下游１６０３，８ｍ处．若将污染带控制在长１０００ｍ、宽５０ｍ内，该排污口酚排放量就应控制在４９．０２ｔ／ａ以内。

Water quality models are presented for estimating the range of contaminated zone of a river and the allowable amount of pollutant discharged on the wastewater discharge point in given range of the zone.The models are applied to study the phenolic contaminated zone of the Changjiang River in Wuhan reach. In the year 2000, the zone will be 4357. 9 m long and 47. 1m wide. The biggest width of the zone will be located in x= 1603. 8 m. If the zone needs to be controled within 1000 m long and 50 m wide, the discharge amount of the discharge point should be less than 49. 02 t/a.
