摘要

For the difference of iron and manganiferous groundwater qualities and spatialrndistribution between the groundwater sources and service regions, different layout ofrngroundwater biological removal of iron and manganese system should be adopted. Itrnwas one of the conditions to prevent the ferromanganese sediment silting raw waterrnpipelines to ensure the service lives of water pipelines. It was important for the securityrnand stability runing of the entire water supply system. In this paper, the layoutrnrelationship between the groundwater biological removal of iron and manganese systemrnand the water supply network were studied. As following recommendations had beenrnmade: 1, to minimize the oxygenation opportunity in the process of iron andrnmanganiferous groundwater be taken and delivered; 2, to take into account of removal ofrniron and manganese water works should be as close as possible to water source duringrnthe establishment of the taking water, purification and delivery of water systems, inrnorder to reduce the length of transmission of water line. Use of these recommendationsrnin practice, achieved good results: the groundwater biological removal of iron andrnmanganese treatment plant had a daily handling capacity of 200,000 tons and therneffluent iron, manganese all was trace amount and met the Chinese standards forrndrinking water quality.
