Description
Technical Field
The invention relates to the field of fertilizer production, in particular to an organic-inorganic compound fertilizer taking a water purification adsorption material as a matrix and a preparation method of the compound fertilizer.
Background
The eutrophication of water mainly comes from untreated or incompletely treated industrial wastewater, domestic sewage, organic garbage, livestock manure and agricultural chemical fertilizers, which cause water quality pollution caused by excessive content of organic substances and nutrients such as nitrogen (N), phosphorus (P), potassium (K) and the like in the water. Lakes such as Taihu lake, dian lake, nest lake and Po Yang lake in China all have the phenomenon of eutrophication of water body caused by the enrichment of nitrogen and phosphorus elements in the water body. Although no toxic substances exist in the water body, the blue algae bloom is often burst, the water quality is deteriorated, and the safety of the drinking water source is seriously threatened. Therefore, water eutrophication is an urgent problem to be solved in water environment quality.
Many wastes in life can be recycled due to being rich in beneficial substances needed by human beings. Such as agricultural wastes, organic plant sources and the like. The agricultural wastes are plant residual objects generated in the production process of agriculture and forestry, residual wastes such as animal wastes in the production process of animal husbandry, agricultural processing residual wastes, rural domestic wastes and the like. The organic plant source is organic plants such as residual plant shells, sawdust, vegetable leaves and the like processed in the life of people. These wastes are not effectively utilized and become a main factor for polluting soil and air environment. According to statistics, only agricultural wastes reach more than 40 hundred million tons every year in China at the present stage. The traditional incineration and landfill disposal mode has serious resource waste, pollutes soil and air environment quality, and cannot be effectively utilized to generate benefits. Therefore, how to recycle agricultural wastes and organic plant resources and supply beneficial substances rich in the agricultural wastes to the natural environment again to generate economic benefits is a problem to be solved urgently at present.
At present, organic-inorganic compound fertilizers on the market are mainly prepared by adding a certain proportion of chemical fertilizers into fully decomposed and fermented organic matters, fully mixing the chemical fertilizers uniformly and carrying out process granulation. In the preparation process, a large amount of chemical substances such as calcium phosphate, urea, ammonium nitrate, potassium chloride and the like are added to provide inorganic nutrient elements required by the fertilizer. So as to enhance the fertilizer efficiency and supplement trace elements required by plants. However, the use of a large amount of chemical substances can cause agricultural non-point source pollution, and the nitrogen, phosphorus and potassium nutrient elements which are not utilized can enter rivers and lakes along with surface runoff, so that the eutrophication phenomenon of a water body is caused.
