Laboratory test Qin Huaihe River of water sample die in a large amount the fish are caused by sanitary sewage
This newspaper reported yesterday Qin Huaihe River presented ten thousand dead fish outside Nanjing, after Nanjing Municipal Environmental Protection Agency received reporter's reflection, send and monitor and monitor personnel at once, begin from water west door, celebrate the door, is comparable to Hongqiao and goes upstream along collecting, the soldier divided two No. externally Qin Huaihe River has carried on water quality and taken a sample to analyze. In arrange and checking, have not found that there are illegal blowdown enterprises around. The enforcer introduces, in view of sense organ of water body, outside color of Qin's water of Huaihe River is yellowish green to blackish green, a few while lasting raft of pontoons section to collecting Fengtai bridge, oil film and rubbish float,river match Hongqiaos south, last grain the dragons silvers is blackish green in color in water in bridge for the rivers, there are black floating things in the river surface, the sense organ is relatively bad. The environment monitoring personnel in Nanjing are seven bridges of urns of Qin Huaihe River outside's from lying separately, military to book it on the check gate of the door, military to book it under the check gate of the door, long dry bridge, the intersection of Fengtai and bridge, collect, celebrate the intersection of door and six monitoring point of bridge and lie in to comparable to Hongqiao and transport grain south river silver the intersection of dragon and bridge of river 8 monitoring points are sampled together, by the look of result of laboratory test, south river and it transports grain to be monitoring data relatively poor in section in river, non- ion sanitary sewage index such as ammonia, ammonia nitrogen, permanganate index among them, about worse than other six sections two to four times. The south river is comparable to water of Hongqiao and dissolve oxygen, ammonia nitrogen density and exceed standard, it is only 0.5mg/L to dissolve oxygen, ammonia nitrogen exceeds standard 8.1 times. And transport Qin Huaihe River celebrates this Section of raft of pontoons from seven bridges of urns to collecting outside for the grain river low reaches, the intersection of ammonia and the intersection of nitrogen and until average 3.49mg/L raise to 10.5mg/L is most large to exceed standard 4.25, dissolve the intersection of oxygen and density until average 7.61mg/L was dropped to 2.64mg/L in the past in the past density. It is reported fish dissolve oxygen lower than 6mg/L to be difficult to survive, it is obvious Huaihe River Qin die fish cause by oxygen deficiency in water this time in water. The expert analyzes, from looking by looking over live and to the preliminary laboratory test data of the water sample quarried, some sections appear the fish may stop production and maintain the transformation to collect the well gate and is correlated with with the east sewage treatment plant of the city very much along the line of Qin Huaihe River this time.
