[0023] A preparation method of activated carbon filter element for water purification is specifically implemented according to the following steps:
[0024] Step 1. Weigh the raw materials according to the following parts by weight: 120-200 parts of activated carbon, 1-3 parts of polyethylene, 10-15 parts of sodium selenite, 8-10 parts of clay, 10-12 parts of magnesium, 5 parts of medical stone -10 parts, deodorant 5-10 parts, attapulgite 20-30 parts, nano-titanium oxide 5-8 parts, tourmaline powder 2-6 parts;
[0025] Step 2, after mixing the raw materials weighed in step 1, grinding and crushing;
[0026] Step 3. Put the mixture obtained in step 2 into a mold and then press it, then put the compressed material into the furnace for sintering heat treatment, keep it in the furnace at a temperature of 300-320°C for 50-80 minutes, sinter it, shape it and release it. The activated carbon filter element is obtained by cooling to 20-30°C and demoulding.
[0027] In step 1, the particle si...
