摘要
2004年8月~2005年3月对温州龙湾区永兴围垦养殖区周边及沿岸氨氮进行了调查检测,结果表明:工业区排放的废水中氨氮含量高于正常水质几十倍,以滨海工业区附近为最高,其次为蓝田工业区、扶贫工业区、高新工业区。工业区以生产合成革、化工、电镀、农药为主,排出的废水中含有高浓度的氨氮,最高检测值为87.5mg/L,废水直排入海,严重影响了周边的生态环境。
Based on investigating and analyzing the samples from circumjacent water area and coastwise of Yongxin inning bread aquatics zone of Longwan district Wenzhou city from August, 2004 to March, 2005, the results showed that the NH4-N content of waste water outletting from industrial park exceeded several ten times of normal quality.The NH4-N content near the Binhai industrial zone ranked first,followed by Lantian industrial zone,Fupin industrial zone,Gaoxing industrial zone.The industrial zone produced mostly compositive-hide, chemical products, galvanoplastics and pesticide.There was the NH4-N of high concentration in the waste water in letting from the industrial zone, the highest content up to 87.5 mg/L.The circumjacent entironment around the sea into which the waste water was drained was seriously polluted.
