鳌江水污染特征及防治对策

The Aojiang River Water Pollution and Treatment

平阳县环境监测站于1998年—2002年对鳌江埭头、江屿、方岩渡、江口渡4个断面的水质进行了监测。结果表明,埭头断面目前属尚清洁,江屿断面属严重污染(以氨氮、挥发酚为主),方岩渡、江口渡断面为中污染段(以氨氮为主);造成鳌江污染的污染源主要是平阳县的制革废水和鳌江沿岸乡镇的生活污水。提出,环保及各级政府部门应加大对鳌江治理投资,尽快建设排污管网及生活污水处理厂;对无能力进行废水处理的小企业,应予以关闭;提倡使用清洁生产工艺,从源头减少制革废水的污染。

Water quality of the AojiangRiver was monitored from 1998 to 2002. The monitoring cross section included Litou, Jiangyu, Fangyandu and Jiangkedu. The water quality in Litou was clean, heavy polluted in Jiangyu (key pollution index was NH_3N and volatile phenol). In Fangyandu and Jiangkedu, water was middle polluted(NH_3N). The main reason of pollution was the tanning waste water and domestic sewage. So the pollution treat invest must be increased. And the blow-off pipe network and domestic sewage treatment plant must be constructed, too. Others included to shut down the polluted-heavy plant, to improve cleaner production to reduce the pollution of tanning waste water.
