Embodiment 1

[0022] Take 2.5g of attapulgite ore powder, activate it in 4% hydrochloric acid dope for two hours, the solid-liquid ratio is 1.2:1, then dry the activated attapulgite powder at a temperature of 300°C for two hours, Then take 2.5g of activated carbon mixed powder to 80 mesh fineness, and make powder 1 for subsequent use.

[0023] Put 1g of powder 1 into 2000ml of raw water containing fluorine and arsenic, stir for 40-60 minutes, and filter with filter cloth or fast filter paper. Treat more than 10,000 tons of raw water and use mechanical filtration.

Embodiment 2

[0025] Take 2.5g of attapulgite ore powder, place it in a roasting furnace, and roast it at a temperature of 360°C for three hours, then take 2.5g of activated carbon mixed powder to a fineness of 80 meshes, and prepare powder 1 for later use, and then add polyaluminum chloride Powdered to 80 mesh fineness, prepared powder 2 for subsequent use.

[0026] Put 1g of powder 1 into 2000ml of fluorine-containing and arsenic-containing raw water, stir for 30 minutes, then put 0.75g of powder 2 into the raw water, continue stirring for 15 minutes, stand still for 3-5 minutes to separate layers, drink the upper part of the water, and discard the slag in the lower part Go (bury the water slag deep in the soil away from the water source).

Abstract

The fluorine and arsenic removing water purifier consists of mainly attapulgite powder and active carbon, and is prepared through activating attapulgite powder, mixing activated attapulgite powder with active carbon in certain ratio, crushing to 80 mesh, crushing polyaluminium chloride powder to 80 mesh and other steps. The fluorine and arsenic removing water purifier has high fluorine and arsenic removing capacity, and can also eliminate inorganic heavy metal ions and polar and nonpolar organic molecules from water. The present invention may be used in purifying various kinds of surface polluted water, domestic sewage and industrial effluent, has low cost, easy use and great water treating capacity, and is suitable for rural district.

Description

technical field [0001] The invention relates to a water purifying agent and a preparation method thereof, more specifically, the invention relates to a water purifying agent for removing fluorine and arsenic and a preparation method thereof. Background technique [0002] Endemic fluorosis, arsenic poisoning and endemic goiter are all caused by the high fluoride and arsenic content in drinking water and the lack of iodine in water. These three endemic diseases spread across 29 provinces, municipalities, autonomous regions and municipalities directly under the central government (except Shanghai). The diseased areas are mainly distributed in the vast rural areas, especially the remote areas with backward economy. The total population of the diseased areas exceeds 100 million, seriously affecting the local people. physical health and economic development. [0003] At present, the defluoridation and arsenic removal technologies adopted by various countries are mainly activated ...
