Embodiment 1
[0017] The method for improving red mud land with electrolytic manganese slag, the proportion of each component by weight is: 123-288 parts of red mud, 78-213 parts of electrolytic manganese slag, 21-67 parts of expanded perlite, 24-56 parts of organic matter, loose soil 1-10 parts of fertilizer, 0-1 part of microbial preparation, 5-18 parts of nitrogen, phosphorus and potassium fertilizer, and 0-1 part of trace additive.
[0018] In the first step, for the selected red mud stockpile or electrolytic manganese slag stockpile, take multi-point sampling according to the area and depth to be improved in the stockpile; due to the material in the red mud or electrolytic manganese slag stockpile will vary depending on the ore, process Therefore, the use of multi-point sampling and multiple simulation tests to determine the improved formula is the basic requirement for the technical route and improved cost;
[0019] The second step is to select the types of plants to be planted accord...

Abstract
The invention discloses a method of utilizing an electrolytic manganese residue to improve red mud land. The method comprises the following steps: mainly utilizing the electrolytic manganese residue to treat red mud, neutralizing the alkali of the red mud with the acidity of the electrolytic manganese residue, treating the waste with processes of the waste against one another, regulating the pH value of the two wastes to a normal range suitable for plant growth at a low cost, adding expanded perlite with strong properties of absorption and adsorption, so as to increase the loose permeability and the moisture retention of the red mud land and increasing the draught resistant ability; adding an organic matter, a soil loosening agent, a microbial preparation, a nitrogen phosphorous and potassium element fertilizer, other element fertilizer and a micro additive, so as to purposefully regulate the plant to normally and generally grow on the red mud land. The method is adopted mainly to regulate proportion of various soil conditioners to process the growth state of various plants on the red mud land, so as to achieve the purpose that various plants can normally and generally grow on the red mud land.
Description
technical field [0001] The invention relates to a soil preparation method for comprehensive environmental management of agriculture or forestry, in particular to a method for improving red mud land by electrolyzing manganese slag. Background technique [0002] Red mud is an insoluble industrial waste that is discharged from alumina plants after alkaline treatment of bauxite. In 2011, the output of red mud in my country was about 45 million tons, and the accumulated stock of red mud reached 250 million tons, occupying more than 40,000 mu of land. At present, the comprehensive utilization rate of red mud in my country is only 4%. [0003] With the development of the aluminum industry and the reduction of the grade of aluminum ore, the discharge of red mud will increase. Red mud must be reprocessed and utilized in order to turn waste into treasure and reduce pollution. At present, a large amount of red mud is still discharged to the storage yard for storage, and the dam is we...
