| 摘 要： | 用生物滴滤床（BTF）处理某化工厂污水站的H2S和挥发性有机物（VOCs）混合废气，当废气中H2S质量浓度为120～400mg／m^3、VOCs质量浓度为115～340mg／m^时，运行稳定后H2S和VOCs的去除率为95％和85％。考察了影响BTF运行的循环水水质情况，试验结果表明：加入Na2CO3可使循环水pH控制在3～6；循环水中含盐量、Cl^-质量浓度和SO4^2-质量浓度分别为2200～3300，600～800，1200～1400mg／L，均未达到抑制微生物的水平。

| Abstract: | The waste gas containing H2S and VOCs from the wastewater treatment plant of a chemical factory was treated in the biological trickling filter(BTF).When the mass concentrations of H2S and VOCs are 120-400 mg/m3 and 115-340 mg/m3,their removal rates in steady operation are 95% and 85% respectively.The quality of circulating water affecting the BTF operation was investigated.The test results show that the pH of circulating water can be controlled at 3-6 with the addition of Na2CO3 and the mass concentrations of salts,Cl-and SO24 are 2 200-3 300,600-800,1 200-1 400 mg/L,respectively.Each of them is below the level of microorganism suppression. |
