[Technical Field] The present invention relates to a novel phosphorus removal agent. [Prior Art] Since phosphorus is a causative substance that causes eutrophication of water quality, it is necessary to remove phosphorus from not only industrial wastewater, but also sewage domestic wastewater, industrial wastewater, and other contaminated water. Conventionally, various methods have been known for removing phosphorus from wastewater, but none of them are yet satisfactory in terms of cost, and there is a desire to develop an inexpensive phosphorus removal agent. [Purpose] The purpose of the present invention is to provide an inexpensive phosphorus removal agent. [Structure] According to the present invention, there is provided a phosphorus removal agent containing a heat-treated residue of oil shale as a main ingredient. The phosphorus removing agent of the present invention has a heat-treated residue of oil shale as a main ingredient. In this case, the oil sierre heat treatment is performed at a temperature of 400-1000℃, preferably 500-1000℃.
The temperature is 800℃. As the phosphorus removing agent of the present invention, general waste oil shale can be used as it is, or preferably it can be further heat-treated before use, and can be obtained at a very low cost. This phosphorus removing agent can be used in various forms such as fine powder or granules. In order to remove phosphorus dissolved in water using the phosphorus remover of the present invention, for the phosphorus remover of the present invention,
All you have to do is bring it into contact with water containing phosphorus. In this case, methods for bringing the phosphorus removing agent into contact with the phosphorus-containing water include a method in which the phosphorus removing agent is introduced into the phosphorus-containing water, and a method in which the phosphorus-containing water is passed through a column filled with the phosphorus removing agent. When removing phosphorus by adding a phosphorus remover to phosphorus-containing water, the ratio of the phosphorus remover to the phosphorus-containing water is usually 0.1 to 10% by weight.
Preferably it is 0.5 to 5% by weight. The processing time is
It usually takes about 30 minutes to 3 hours. [Effects] The phosphorus removal agent of the present invention is applicable to the removal of phosphorus from various wastewaters containing phosphorus. In this case, the phosphorus remover that has adsorbed phosphorus can be effectively used as a phosphorus fertilizer because the adsorbed phosphorus component is soluble. [Example] Next, the present invention will be explained in more detail with reference to Examples. Example 1 As a phosphorus removal agent, waste oil shale from Colorado, USA, which was carbonized at 500 to 600°C and whose composition is shown in Table 1 below, and its heat-treated residue were used.

る。[Table] The heat treatment of the waste oil siel was carried out in an electric furnace at 200 to 1000°C for 2 hours. Next, the above-mentioned waste oil shale and its heat treatment residue were used as a phosphorus removing agent, and this was converted into sodium hydrogen phosphate (Na 2 HPO 4 ) as a phosphorus compound.
Add 0.001 mol to an aqueous solution of 100 ml of water,
After stirring and mixing at 25° C. for 2 hours, the phosphorus removing agent was filtered, and the residual PO 4 3 in the filtrate was measured, and the phosphorus removal rate was calculated based on the measurement results. The results are shown in the table below. In addition, in Table 2, the phosphorus removing agent whose heat treatment temperature is 0 means waste oil siel itself.

In addition, in Table 3, the phosphorus removing agent whose heat treatment temperature is 0 means unheat-treated oil shale itself.
