Pollution Prevention Countermeasures of Chemical Industry in the Haihe Basin
Chemical industry in Haihe Basin is the second largest polluting industries. The emissions of COd and NH3-N of chemical industry in 2007 accounted for 18% and 44% of the total watershed, while the emissions of COD less than paper industry and the emissions of NH3-N more than that. Based on the environmental statistics of Haihe Basin in 2007, the paper analyzes the rate of standard reaching, structural pollution characteristics, water use efficiency and the level of pollution control of chemical industry in the Haihe Basin. It suggests that, if all the enterprises achieve the secondary standard, the emissions of COD and NH3-N can decrease by 38% and 11%; If they can meet the primary standard, the emissions of COD and NH3-N can decrease by 62% and 70%. Eventually, the pollution control measures such as achieving or raising the emission standards, adjusting industry structures are proposed.
