A material for a carrier structure for a group of effective microorganisms, prepared by kneading one part by weight of cement together with a mixture of 2-3 parts by weight of coarse crushed particles prepared by crushing a tourmaline ore to a size of 1 to 20 mm, 2-3 parts by weight of a coarse powder prepared by crushing a tourmaline ore to a size of 1 mm to 100 mu m, and 2-3 parts by weight of a tourmaline powder prepared by crushing a tourmaline powder and sieving the powder with a 100 mu m sieve to obtain an undersize fraction, an EM fermentation material in an amount of 10-100 % by volume of the mixture, and a suitable amount of water to prepare a concrete-like material. This material can be used to reduce water pollution of rivers and, in addition, can improve the efficiency of wastewater treatment equipment. |
