摘要
对弹性立体填料可变孔曝气软管曝气接触氧化工艺处理苏南农村微污染水塘水进行了中试研究,探索了该工艺的最佳运行参数,试验表明:在水力停留时间为1.7 h,气水比(0.8～1.2)∶1的运行条件下,该工艺取得了良好的NH3-N和CODMn去除效果,即使在进水含有高浓度藻类的情况下,该工艺还是保持了很高的藻类去除率。
The paper undertakes the pilot-scale research on the treatment of slight pollution pool water in rural areas of South of Suzhou by adopting the aeration hose contact oxidation of elasto-steric packing variable orifice,explores the optimal operation parameter of the craft,proves by the test that the craft achieves better removal effect for NH 3-N and COD Mn with the 1.7 h of the hydraulic retention time and the operation conditions with the gas-water ratio from（0.8 ～ 1.2） ∶ 1,and the craft maintains higher removal ratio for algae in spite of the high-density algae.
