- Abstract:
- Groundwater is widely used in rural areas of northern Anhui, and there are some cases of excessive iron, manganese and fluorine. The second batch of rural drinking water safety consolidation and upgrading project was launched in 2019 in Mengcheng County, Anhui Province. In Luoji Waterworks, the water source was replaced by surface water from Cihuaixin River, a water treatment workshop was expanded with a design capability of 15 000 m3/d and effluent was sent to the clear-water reservoirs for Luoji and Licang Waterworks after treatment. The stainless steel water purification device mainly adopted the process of pre-ozone, mechanical mixing, grid flocculation, inclined pipe settlement, V-type filter and post-ozone, as well as activated carbon sand filter. Commissioning was completed in May 2020. At present, the daily water supply is 11 000 m3/d, and all the effluent indexes are superior to the standard of drinking water, including turbidity of 0.172 NTU.
