Preparation method and device of soil improvement type organic fertilizer

Abstract

The invention relates to the technical field of soil improvement, in particular to a preparation method of a soil improvement type organic fertilizer. The preparation device is used in the preparation method, and the preparation device comprises an electrolytic tank, a cathode bar, an anode bar, a power source and a recovery unit. The cathode bar and the anode bar are arranged in the electrolytic tank, the cathode bar is rotationally arranged in the electrolytic tank, the recovery unit comprises a flexible belt, an unwinding disc and a winding disc, and the flexible belt starts from an execution part of the unwinding disc to wind the cathode bar for several circles and then is wound on an execution part of the winding disc. The preparation method comprises the following steps of S1, electrolyzing an organic stock solution by the cathode bar and the anode bar; S2, analyzing the heavy metal on the cathode bar, and adsorbing the heavy metal on the flexible belt; S3, enabling the unwinding disc and the winding disc to work to replace the flexible belt on the cathode bar. According to the present invention, the heavy metal in the organic stock solution is removed in an electrolysis mode, the heavy metal can be recycled, the cost is low, and the content of the heavy metal in the prepared organic fertilizer is lower. The invention further relates to a preparation device of the soil improvement type organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a method for preparing a soil-improving organic fertilizer. The invention also relates to a soil improvement type organic fertilizer preparation equipment. Background technique [0002] Farmers in our country have a tradition of using organic fertilizers and attach great importance to the use of organic fertilizers. The United States, Western Europe, Japan and other developed countries are emerging "ecological agriculture" and "organic agriculture". These countries also attach great importance to the use of organic fertilizers, and stipulate organic fertilizers as the main fertilizer source for the production of green food. Organic fertilizer refers to a type of fertilizer that contains organic substances and can not only provide a variety of inorganic and organic nutrients for crops, but also fertilize and improve the soil. High-quality organic fertilizer contains a v...

Problems solved by technology

[0005] The device separates the heavy metals in the organic fertilizer through the passivation solution. The organic fertilizer is easily diluted and eliminated by the passivation solution, and the loss of the organic fertilizer is relatively large.
