The 95.86% COD_Cr and 95.21% NH₃-N of Lan Gan weir 97.11% COD_Cr and 97.92% NH₃-N of the Long Zhua weir 97.73% COD_Cr and 97.18% NH₃-N of Hong Guangyou branch canal were from above two sources.According to the development programming, the Hi-technology area will cacel the first industry abolish the domestic animal breeding consummate the sewage pipe-net repair the above three rivers and increase the ability of the sewage disposal.
