Abstract
Tieshan port is an important industrial area in the Beibu gulf economic zone.As the economy in this area develops rapidly,heavy metal pollution and its prevention have been focused.Based on the investigation of heavy metal pollution in Linhai industrial zone of Tieshan port in Guangxi from 2011 to 2012,the environment quality of this area was assessed using single factor index method.Environmental impact of pollutant emission was also predicted and analyzed,and the prevention and control measures for heavy metal pollution were proposed on the basis of the investigation and analysis.The results show that the main heavy metals are discharged within the standard;the main gas pollutants are plumbum and nickel; solid waste is recycled; the main waste water pollutant is chromium,and most waste water is reused;maximum ground concentration range of heavy metals from waster gas is one kilometer around the pollution source;the heavy metals in the marine water,ground water,surface water and soil have no significant change,which shows that pollution in this area is in low level.Integrated pollution prevention and control measures include promoting regional circular economy construction; reducing pollutants and emissions,transforming traditional manufacture industry into industrial eco-chain;strengthening the pollution source management,preventing leachate loss,targeted lead and chromium in wastewater treatment; strengthening the pollotion gross control; improving the management level,preventing pollution transfer; paying more attention to the construction of early warning emergency system.Through these measures proposed in this paper,we keep heavy metal pollution at lower levels in Linhai industrial zone of Tieshan port and reduce its harm to the environment.关键词
