官厅水库微污染快速渗滤处理系统启动试验研究

Study on Start-up Test of Rapid Infiltration Treatment System of Guanting Reservioir Slightly Polluted Water

采用快速渗滤处理系统处理官厅水库微污染水,以河砂或风尘砂为滤料,以水库底泥或污水处理厂的活性污泥作为接种微生物进行系统启动阶段微生物培养试验.同时,人为调节系统水力负荷,对启动过程中的各种条件进行了系统的研究.当系统达到稳定状态时,COD去除率可达59 9%～69 3%,各项指标均可达到地表水三类水质标准.

Rapid infiltration treatent system was used to rteat Guanting Reservoir slightly polluted water,river sand or windblown sand was used as infiltration packing and reservior sludge or activated sludge from waste water plant was used as inoculation microbe to start microbe cultivation test at start-up stage of system.Meanwhile,hydraulic loading of system was adjusted artificially,and various conditions of start-up stage were dicussed.When stable situation was acquired,the removal ratio of COD was 59.9%～69.3%,and each index could attain the third level surface water quality standards.
