Description
Technical field
The present invention relates to Nutrition Soil, be specifically related to a kind of production method of sludge carbonization 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.
Mud is the smelly paste of a kind of easy corruption that produces in sewage treatment process, it is enriched the pollutent in sewage, containing hazardous and noxious substances such as the nutritive substances such as a large amount of nitrogen, phosphorus and organism, viral micro-organisms, parasitic ovum, heavy metals, without effectively processing disposal, produce serious harm by environment.Sludge moisture content >=80% that municipal sewage plant produces, mud is mostly in alkalescence, and pH value is 8 ~ 10, the product of unsuitable direct production recycling.
Investigation display, current China has the mud of 80% not to be effectively addressed, and even has and is simply discarded in the PE such as farmland, river greatly, become new source of pollution.
At present the mud of a large amount of non-stabilizing treatment has become the heavy burden of sewage work, and mud that is how that output is huge, complicated component carries out properly processing safely, make that it is innoxious, minimizing, resource utilization, become deeply concerned key subjects.
Summary of the invention
The object of the invention is to overcome weak point in prior art, a kind of production method of sludge carbonization Nutrition Soil is provided.
The production method of sludge carbonization Nutrition Soil: first the batching of sludge carbonization soil stirred and be squeezed into platy shaped particle, charing is treated to sludge carbonization soil, then by the batching granulation of sludge carbonization Nutrition Soil and sterilizing, is packaged as the finished product of sludge carbonization Nutrition Soil.
Sludge carbonization Nutrition Soil is made up of the waste after mud, active white clay waste slag, attapulgite clay, wilkinite, zeolite, pulverizing, the waste after bubble system, vermiculite, diammonium phosphate, perlite, ferrous sulfate and High hydrophilous resin.
Containing a considerable amount of nitrogen, phosphorus, potassium and trace element in the mud of city domestic sewage treatment plant, through suitable art breading, as cultivation medium soil, soil improvement material, also can be used as the raw material making fertilizer, the mud that the present invention selects city domestic sewage treatment plant to discharge, water content≤85% of mud.
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.
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.
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 after pulverizing, particle fineness≤0.5 millimeter of zeolite.
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 stalk of farm crop, wood chip, bamboo bits and leaf the like waste being dried, and the present invention selects 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.
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.
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.
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 the conditioning of mud charing 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 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.
