Abstract

The invention relates to a water purification biological material and a preparation method thereof. The water purification biological material consists of a solid raw material, water, biological enzyme and biological fungicide, wherein the solid raw material comprises the following components by weight percent: 50 to 70 percent of iron ore slag, steel factory blast furnace slag or converter slag,10 to 40 percent of granite powder, and 5 to 20 percent of a binder, and the sum of the weight percent of the three raw materials is 100 percent; the consumption of water is 15 to 30 percent of the weight of the solid raw material, the consumption of the biological enzyme is 0.01 to 0.1 thousandth of the weight of the solid raw material, and the consumption of the biological fungicide is 0.01 to 0.1 thousandth of the weight of the solid raw material. The preparation method comprises the following steps: mixing raw materials, forming or pressing forming by virtue of a grinding tool to obtain block-shaped or spherical product with a specific gravity of 2.0 to 3.0. The water purification material is mainly inorganic material Fe, the quality is approximate to cobbles, the water purification biological material can be used for directly substituting the gravels to be laid on banks of river and the bottom of water and can be prevented from being flushed away by rip current or flood water in anatural environment. The water purification biological material contains complexing iron ions and has a curing effect for nutritional phosphor salts.

Description

technical field [0001] The invention belongs to the field of water purification materials, and in particular relates to a water purification biological material and a preparation method thereof. Background technique [0002] The key to the treatment of eutrophic water bodies is to inhibit the upturning of nutrients in the bottom sediment. However, dredging and dredging are mostly used in China at present, and the cost of mechanical labor is huge, and because it is only a temporary reduction, it cannot be controlled later. repeatedly. The use of chemical principles for treatment is more common to treat the bottom with slaked lime or to use chemical agents (flocculants such as polyferric chloride) to quickly purify water in a short period of time. However, the action time is short and the water quality repeats quickly, and the flocculant will cause secondary pollution to the environment. The more common method of physical principle treatment is: use zeolite, medical stone, a...
