PURPOSE:To efficiently purify various kinds of water such as tap water, boiler water or river sewage, by immersing a sintered molded product of radiative marble and zeolite, etc., in water to treat said water while treating the treated water with low voltage high frequency discharge. CONSTITUTION:Raw water is supplied to a rotary screen 2 by a pump 1 through a conduit to be filtered and the surface of the rotary screen 2 is washed by a shower 4 while washing water is collected on a trough 3 and made to flow down to be recovered in a sludge accumulation canister 5. The raw water from which sludge is removed is recovered by a receiving tray 6 to be introduced into a tank 7 packed with a radiative ore and zeolite stone to catalytically reduce the impurities in raw water while raw water is irradiated with radioactive rays to be sterilized. Subsequently, raw water after adsorption is filtered to be supplied to a filter 9 from a chamber 8 and further filtered to be sent in a high frequency discharger 10 by a pump 11 to perform discharge treatment.
