YSH-人工湿地系统在造纸废水处理中的工程应用分析

Application Analysis of YSH-Constructed Wetland System to Treatment of Papermaking Wastewater

对YSH-人工湿地系统处理造纸废水的工艺及工程效益进行了分析.结果表明,在进水pH值为7.30-7.80,COD,BOD和SS的浓度分别为1700,611,332 mg·L^-1别为1630,580,260 mg·L^-1.系统运行稳定,出水水质达到排放标准且可用于农业灌溉,经济效益和环境效益良好.

The technology and engineering benefits of wastewater from paper making with YSH-constructed wetland system was studied experimentally. The result showed that, when pH = 7.30 - 7.80, COD, BOD and SS were 1 700, 611 and 332 mg mg·L^-1, respectively, the removal rates of COD,BOD and SS were 96.6% ,96.4% and 77.7% respectirery. The decrease of the concentration is 1 630, 580, 260 mg·L^-1; The performance of the system was stable and the quality of the effluent could meet the wastewater discharge standard, and it could be reused for agricultural irrigation, producing good economic and environmental benefits.
