Description
Technical field
The present invention relates to Nutrition Soil, be specifically related to the production method of a kind of zeolite mine tailing charing Nutrition Soil.
Background technology
The Nutrition Soil raw material that existing flower plants and nursery stock uses is formulated by material mixing such as mountain mud, garden mould, pond sludge, peat soil, river sand, plant ash, wood chip, agricultural crop straw, mushroom cultivation dead meal and soil ulmin mostly, these Nutrition Soils are not through reasonably preparing burden and sterilization, preserve moisture and fertility ability, permeability is bad, easily harden, mineral matter nutritional in Nutrition Soil is difficult to be absorbed by flower plants and nursery stock, flower plants and nursery stock also can be subject to the virus and bacteria in soil and newly sprout the infringement of weeds, is unfavorable for that the normal growth of flower plants and nursery stock is grown.
Phosphorus and potassium are all that flower plants and nursery stock grows required nutritive element, although containing a certain amount of phosphorus and potassium in Nutrition Soil, but major part belongs to late effect property phosphorus and potassium, directly can not be absorbed by flower plants and nursery stock root system, cause flower plants and nursery stock poor growth, the normal growth affecting flower plants and nursery stock is grown, therefore, phosphorus in Nutrition Soil and potassium, need be converted into solubility rapid available phosphorus and potassium directly could be absorbed by plant.
Mineral Resources in China 80% is intergrowth mineral, a large amount of valuable phosphorus, potassium and trace element retain among mine tailing, tailings impoundment needs to take a large amount of soil, a lot of Tailings Dam exceeds the time limit or excess load uses, even violation operation, make Tailings Dam there is great potential safety hazard, serious threat is caused to people's property of surrounding area and life security.
Current zeolite is mainly used for producing cement, and the zeolite mine tailing much not meeting cement mill quality standard abandons in a large number in mining area.
Summary of the invention
The object of the invention is to overcome weak point in prior art, provide a kind of zeolite mine tailing to carbonize the production method of Nutrition Soil.
The production method of zeolite mine tailing charing Nutrition Soil: first the batching of zeolite mine tailing charing soil is stirred and be squeezed into platy shaped particle, charing is treated to zeolite mine tailing charing soil, again by the batching granulation of zeolite mine tailing charing Nutrition Soil and sterilizing, be packaged as the finished product of zeolite mine tailing charing Nutrition Soil.
Zeolite mine tailing charing Nutrition Soil is made up of the waste after zeolite mine tailing, active white clay waste slag, mud coal, attapulgite clay, wilkinite, pulverizing, the waste after bubble system, vermiculite, diammonium phosphate, perlite, High hydrophilous resin and ferrous sulfate.
Zeolite is the general name of a kind of moisture alkali or alkaline-earth metal rack-like aluminium silicate mineral, the internal structure of its uniqueness and crystal physico-chemical property, make it have the excellent physicochemical properties such as absorption, ion-exchange, catalyzed reaction, acidproof, heat-resisting and radiation hardness, being agriculturally used as soil improvement agent, fertilizer conservation, water conservation can being played, prevent disease and pest.The present invention selects the zeolite mine tailing after pulverizing, particle fineness≤0.5 millimeter of zeolite mine tailing.
Atlapulgite is with attapulgite clay, wilkinite and gac for raw material, the sorbent material that the activity processed through acidification is higher, is widely used in grease-decolor; Atlapulgite after decolouring loses activity, can not regenerate and reuse, become a kind of auburn active white clay waste slag, in active white clay waste slag, oil length is up to 15 ~ 40%, active white clay waste slag is after again recycling, still remain the grease of 5 ~ 25%, these active white clay waste slags not only can produce spontaneous combustion, and serious environment pollution, at present, most of oil factory adopts water to spray or melt pit is buried, and as offal treatment, causes resource to waste.
Mud coal is a kind of byproduct in coal production process, Qi Zhongyou: mud coal, waste dump that the floating tail-coal of Oversized Coking Coal Cleaning Plant, the mud coal of coal-water mixture output, mine drainage are carried secretly water the mud coal washing away; There is due to mud coal many unfavourable condition such as high-moisture, high viscosity, high retentiveness and low heat value, be difficult to realize industrial application, kept outside of the door by user for a long time, containing more phosphorus, potassium and trace element in mud coal, but directly can not be absorbed by plant, the present invention selects the mud coal after pulverizing, particle fineness≤0.5 millimeter of mud coal.
Attapulgite clay has unique dispersion, high temperature resistant, anti-good colloidal property and the higher adsorptive power such as saline and alkaline, and has certain plasticity-and cohesive force.Attapulgite clay can adsorb foreign odor taste, heavy metal ion and carcinogenic substance in Nutrition Soil, the nutritive ingredient in Nutrition Soil is kept not run off, be conducive to growing of plant, the present invention selects the attapulgite clay after pulverizing, particle fineness≤0.5 millimeter of attapulgite clay.
Wilkinite is the moisture clay pit based on montmorillonite, because it has special character, as bloating tendency, cohesiveness, adsorptivity, catalytic, thixotropy, suspension and cationic exchange, wilkinite has stronger water absorbability and swelling property, adsorbable 8 ~ 15 times to the water yield of own vol, volumetric expansion can reach several times to 30 times, can be dispersed into as a form of gel and suspension in water medium, the present invention selects the wilkinite after pulverizing, bentonitic particle fineness≤0.5 millimeter.
The stalk of a large amount of farm crop, wood chip, bamboo bits, leaf and bark the like waste, be discarded in around farmland or roadside, mostly burned fall, severe contamination Air quality; Waste after pulverizing pulverizes after the straw of farm crop, wood chip, bamboo bits and leaf the like waste being dried, waste length≤25 millimeter after pulverizing.
Vermiculite after high-temperature roasting, its volume energy undergoes rapid expansion several times to tens times, the vermiculite after volumetric expansion, expanded vermiculite, is one of the lightest in the world mineral; Expanded vermiculite is used as soil improvement agent, can improve the structure of soil, and water storage preserves soil moisture, and improves the ventilation property of soil and aquosity, plays the multiple actions such as fertilizer conservation, water conservation, water storage, ventilative and mineral manure.The present invention selects the vermiculite after pulverizing, particle fineness≤0.5 millimeter of vermiculite.
Perlite becomes a kind of lightweight, multifunctional novel shaped material through expansion, have the features such as apparent density is light, thermal conductivity is low, chemical stability is good, and pearlstone is fertilizer conservation, water conservation, aseptic, good permeability on agricultural, gardens.The present invention selects the pearlstone after pulverizing, particle fineness≤2.0 millimeter of pearlstone.
Diammonium phosphate is a kind of readily avaiable fertilizer of high density, is applicable to various crop and soil, is specially adapted to the crop that nitrophilous needs phosphorus, makes base manure or topdress.
The water absorbent rate of High hydrophilous resin can reach hundreds of times even thousands of times of own wt, and the present invention selects the water absorbent rate of High hydrophilous resin to be 100 ~ 300 times.
Ferrous sulfate is pale green crystals, the ferrous sulfate of 10% aqueous solution is acid to reindeer moss, pH value is about 3.7, in the present invention for regulating zeolite mine tailing to carbonize the pH value of Nutrition Soil and the supplement as plant ferro element, physiological disturbance is there is in control plant because of iron deficiency, make leaf look chlorosis, can also be used to kill liver moss.
The present invention is achieved by following technical proposals:
