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
The present invention relates to the method for soil preparation of a kind of comprehensive environmental improvement agricultural or forestry, be specifically related to the method on a kind of electrolytic manganese residues improvement red mud ground.
Background technology
Red mud is the insoluble industrial residue dumped after alumina producer alkaline process process bauxite.The output of China's red mud in 2011 is about about 4,500 ten thousand tons, and the accumulation volume of cargo in storage of red mud reaches 2.5 hundred million tons, and land occupation is more than 40,000 mu.The red mud comprehensive utilization ratio of current China only has 4%.
Along with the development of aluminum i ndustry and the reduction of aluminum ore grade, red mud quantity discharged, by increasing, must be used to red mud reprocessing, decreasing pollution of just turning waste into wealth.Red muds a large amount of at present is still discharged into stockyard and piles up, and wet method of building a dam is stored up, and be separated by natural subsidence and return use again to solution, this method easily makes a large amount of waste lyes penetrate into neighbouring farmland, causes alkalization of soils, paludification, polluted surface underground water source.
At present, in world wide, waste constantly increases, and red mud causes increasing technology, economy and environment problem.The external general row of employing disposes red mud in sea.Domestic Ji Jia aluminium manufacturer is all positioned at province, inland, and the expense of sea disposal is too high.Along with society is to the attention of environmental protection work, an urgent demand aluminum oxide industry realizes harmless emission or zero release.The comprehensive utilization aspect of red mud, comprises and refine iron and the recovery metal such as aluminium, titanium, vanadium, scandium wherein from red mud; Utilize the calcium in red mud, silicon, aluminum for devitrified glass and porous ceramic grain; After carrying out dealkalize process to red mud, for manufacture of cement; For the production of red mud brick; As road basement material etc.Although Technology is numerous, red mud comprehensive utilization ratio only has 4%, and major cause is summarized as: one is that processing cost is too high; Two is that to eat the quantity of slag little; Three is produce secondary pollution.
Summary of the invention
The object of the invention is to based on electrolytic manganese residues, red mud is processed, make it recover the ecological functions of soil, reach the treatment of wastes with processes of wastes against one another, naturally process the difficult problem of environmental protection of electrolytic manganese residues and red mud, finally enable plant at red mud general normal growth on the ground.
For achieving the above object, technical scheme of the present invention is: the method on electrolytic manganese residues improvement red mud ground, each component share is by weight: red mud 123 ~ 288 parts, electrolytic manganese residues 78 ~ 213 parts, pearlstone 21 ~ 67 parts, organic 24 ~ 56 parts, loosing soil agent 1 ~ 10 part, microbial preparation 0 ~ 1 part, NPK fertilizers 5 ~ 18 parts, trace mineral supplement 0 ~ 1 part.
The first step, to selected red mud dump or electrolytic manganese residues stockyard, needs area, the degree of depth multidraw in proportion of improvement according to stockyard; Because the material in red mud or electrolytic manganese residues stockyard can, because ore, technique and the factor of time change, so employing multidraw repeatedly simulation test determines improved formulations, be the basic demand of technological line and improvement cost;
Second step, selectes according to the geographical position in stockyard, weather condition the floristics that will plant; Select according to the geographical position in stockyard, weather condition the floristics that will plant, improve plant survival rate on the one hand, also reduce improvement cost on the other hand;
3rd step, needs area, the degree of depth of improvement, carries out repeatedly simulation test, determine and optimize improved formulations with got red mud sample at testing ground according to stockyard;
4th step, chooses the certain area needing to improve stockyard in proportion, does and expand experiment, again determine and optimize improved formulations;
5th step, by again to determine and the improved formulations optimized improves whole stockyard.
When adopting technique scheme, be main to process red mud with electrolytic manganese residues, with in the acidity of electrolytic manganese residues and the alkalescence of red mud, the treatment of wastes with processes of wastes against one another, makes the pH value of two kinds of wastes all adjust back to the normal range of suitable for plant growth at low cost; The pearlstone added has very strong absorption absorption property, can increase loose permeability and the moisture retention on red mud ground, improve its drought-resistant ability.Element fertilizer and the trace mineral supplement such as organic matter, loosing soil agent, microbial preparation, N P and K that add, mainly specific aim regulating plant generally normally can grow on the ground at red mud.Mainly by the proportioning of the various soil improvement agent of adjustment, process each kind of plant at red mud growth conditions on the ground, reach the object that each kind of plant can generally normally grow at red mud on the ground.By to the material of human hazard mainly heavy metal element process give the Nature.Through one or many process, plant can generally normally grow in stockyard again, although stockyard growing plants temporarily can not utilize by the mankind, the objectionable impurities in stockyard, to the harm of the mankind, can reduce year by year, finally inherently eliminate.In aforesaid method, employing multidraw repeatedly simulation test determines improved formulations, progressively expanding test improves whole stockyard, the technique effect brought is low cost improvement stockyard, the treatment of wastes with processes of wastes against one another, enables plant normally generally grow on the red mud that not even a blade of grass grows ground or electrolytic manganese residues on the ground, by the successive procreation of plant and microorganism and animal, reduce the objectionable impurities in stockyard year by year, eliminate its harm until final.
Further, the composition of described organic matter be carbohydrate, Mierocrystalline cellulose, xylogen, containing N compound, fat, resin, wax, tannin and ashy substance.
Further, the composition of described loosing soil agent is xanthohumic acid, Ulmic acids, plant cellulose, activation weathered coal.
Further, the composition of described trace mineral supplement is manganese, boron, zinc, copper, molybdenum, nickel.
