A method includes preparing a natural seashell, calcining the seashell at a high temperature to clear organic substances from the seashell, processing and reacting the seashell at a high temperature, and grinding and screening the seashell, to form a water purifying agent. The water purifying agent includes a powder having a porous structure. The powder has an interior provided with a plurality of pores. Thus, the water purifying agent is used individually or served as a carrier of a microorganism for a specified purpose, so as to purify the water quality. In addition, the water purifying agent has a high specific surface area and has a better adsorption capacity. 1. A method for making a water purifying agent , comprising:preparing a natural seashell;calcining the seashell at a high temperature to clear organic substances from the seashell;processing and reacting the seashell at a high temperature; andgrinding and screening the seashell, to form a water purifying agent with a porous structure;wherein the water purifying agent is used individually or served as a carrier of a microorganism for a specified purpose, so as to purify a water quality.2. A water purifying agent comprising:a powder having a porous structure;wherein:the powder has an interior provided with a plurality of pores;the powder is made of a natural seashell which is processed at a high temperature, and is ground and screened to form the porous structure; andthe powder is used individually or served as a carrier of a microorganism for a specified purpose, so as to purify a water quality.3. The water purifying agent of claim 2 , wherein the powder has a diameter of 0.4-10 μm. The present invention relates to a water purifying technology and, more particularly, to a water purifying agent and the method for making it.A conventional water purifying method comprises directly discharging water from the entire water area (such as the pond or the like) and then injecting clean water into the water area. ...
