The invention discloses application of iron sulphide ores and a method for adsorbing trace phosphor in water by using the iron sulphide ores. With respect to the application of the iron sulphide ores, the iron sulphide ores are used as an adsorbing material for adsorbing trace phosphor in water, and an application method comprises the steps of: crushing the iron sulphide ores, sieving to obtain granules with the grain diameter of 0.1-1mm or adding a binder for granulation to obtain the granules with the grain diameter of 0.1-1mm, filling the granules to form a filter column, injecting water with phosphorous mass concentration of lower than 3ppm into the filter column, controlling the flow velocity of a filter liquid to be 0.1-6m/h, and collecting filtrate. By means of the invention, the phosphorous content in the water is decreased to be below 0.1ppm from 0.5-3ppm, so that the phosphorous concentration of drained domestic sewage is decreased to a level within a phosphorous concentration ...

The invention discloses a method for preparing nano iron by taking iron oxide as a raw material and application of the nano iron. The method is characterized by comprising the following step: preparing the nano metal iron by reducing iron oxide through hydrogen at the temperature of 450-850 DEG C. The nano iron prepared by the method has high removing rate on arsenic, hexavalent chromium and nitrate nitrogen in water and can be widely used for the processing and the in-situ remediation of underground water containing the arsenic, the hexavalent chromium and the nitrate nitrogen.

The invention discloses a preparation and regeneration method for water treatment defluoridation filter material based on a natural mineral. The invention is that natural bauxite ores are used as raw materials, are roasted at high temperature at two stages after crushing, screening and pretreatment through hydrochloric acid, and finally are cooled to obtain the defluoridation filter material. After the defluoridation filter material loses efficacy, the defluoridation filter material can be reused after inorganic aluminum salt solution is used for soaking the defluoridation filter material. The invention has the advantages that the water treated by using the defluoridation filter material can fully satisfy the standard that fluorine content in drinking water is lower than 1.0mg/L, the source of the raw materials is wide, the preparation is simple and convenient, the cost is low and the application prospect is good.
