摘要
近几年来，廊坊市在水生态、水环境保护方面虽然取得了一定的进展，但是环境污染形势严峻的状况仍未得到明显改变。在经济快速增长，资源能源消耗大幅增加的情况下，污染物大量排放致使水体环境容量超标，主要污染物为氨氮、高锰酸盐指数、挥发酚、氟化物等。根据2009年廊坊市地表水和地下水水质监测评价分析显示，全市地表水中有水的297km河流河段全部评价为劣V类水质；全市浅层地下水水质也受到了不同程度的污染。在23眼水质监测井中，评价为Ⅰ、Ⅱ类水各1站次，分别占监测井总数的4．35％；Ⅲ类水2站次，占监测井总数的8．70％；Ⅳ类水（适用于工业、农业用水）7站次，占监测井总数的30．4%；Ⅴ类水12站次，占监测井总数的52．2％。并且南部地区受到污染程度比北部地区严重。
In recent years, Langfang city has made some progress on the water eco-environment protection. But the environmental pollution sta-tus has not obviously improved. As the fast growth of economy, more and more pollutants discharge far beyond the water environmental capaci-ty. The main pollutants are ammonia, nitrogen, permanganate index, volatile phenol, fluoride, etc. According to the analysis of water quality monitoring and evaluation in 2009, the water in the city＇s 297km river section was evaluated worse than Grade V; the city＇s groundwater quality in one station reaches Grade Ⅰ, and Grade 11 in another water station, accounting for 4. 3% in the total number of 23 monitoring wells; the wa-ter from two water stations reaches Grade Ⅲ, 8. 7% of the total monitoring wells; the water from seven water stations reaches Grade Ⅳ （for industrial, agricultural water use）, 30. 4% ; the water from 12 water stations reaches grade V, 52. 2%. The water pollution in the south is worse than in the north.
