Abstract

The invention relates to a rare-earth porcelain sand filter material ball for removing organic matters and a preparation method thereof. The rare-earth porcelain sand filter material ball comprises the following raw materials of: by weight, 10-12 parts of rare earth, 25-35 parts of sticky loess, 40-60 parts of porcelain sand, 9-16 parts of a calcium carbonate stone powder, and 2-5 parts of a binder. The preparation method of the rare-earth porcelain sand filter material ball comprises the following steps of: weighing rare earth, adding a modifier into the weighed rare earth; immersing the configured raw materials in water, followed by the addition of porcelain sand to ferment; adding the calcium carbonate stone powder, the sticky loess and the binder into the processed raw materials, followed by machining processing to form a globoid; placing the prepared globoid into a porcelain sintering kiln to sinter; and naturally cooling after the sintering for molding. As voids on the sphericalsurface and in the filter material are distributed uniformly with large void fraction, the rare-earth porcelain sand filter material ball for removing organic matters in the invention has good anti-pollution performance.

Description

technical field [0001] The invention belongs to the technical field of water purification, and in particular relates to a rare earth porcelain sand filter material ball for removing organic matter and a preparation method thereof. Background technique [0002] At present, China is facing a serious water quality crisis, and water pollution has become a serious threat. The causes of China's water pollution are complex, wide-ranging and large-scale, with many types of pollutants and high loads, which have greatly exacerbated China's water scarcity, threatened the public's health and living standards, and caused huge social and economic losses. Since 1999, the discharge of domestic sewage in Chinese cities began to exceed the discharge of industrial wastewater. In the process of agricultural production, the use of chemical fertilizers has been increasing year by year. The pollution of groundwater in some areas is becoming more and more serious, and water pollution accidents hav...
