Abstract
The invention relates to a method for producing a soil amendment by using papermaking black liquor wastewater and waste paper sludge, which is characterized by comprising the following steps: carrying out a neutralization reaction on the black liquor wastewater and the waste paper sludge from a paper mill and furfural waste liquid, waste mother liquor from a cystine plant, waste acid liquor from a gourmet powder factory, pickling waste liquor from a zinc plating plant and waste liquor containing ferrous sulphate from a titanium pigment plant; adsorbing with calcium superphosphate and humic acid, and meanwhile mixing and activating medium and trace nutrient elements and beneficial elements in alkali, and adjusting to reach the optimum pH value of 5-8, thus obtaining the soil amendment. In the invention, the soil amendment produced with the papermaking black liquor wastewater and the waste paper sludge has the following obvious advantages: loosening soil aggregate, radically treating saline and alkaline land, causing crops to have developed root system, flourish leaves, thick and strong straws, and full seeds, and increasing crop disease resistance. Due to drought resistance, saline-alkali tolerance and greatly-increased crop yield, the soil amendment is an effective organic compound fertilizer.
Description
Technical field
The present invention relates to a kind of natural soil-conditioning material or soil-stabilising material of coming from, be specifically related to a kind of method of utilizing papermaking black liquor wastewater, waste paper sludge to produce soil improvement agent.
Background technology
Acid soil mainly is distributed in southern area, and kind has: brown earth, cinnamon soil, Lou soil, grey cinnamonic soil, anthropogenic-alluvial soil etc.Alkaline soil is distributed in northern area more, and kind has: alkaline earth, loessal soil, black mature soil, brown soil, chestnut soil etc.Acid soil is the mineral soils of many places in the areas of high temperature and rainfall, organic matter in its soil constitution and nutrient poorness and mineral content height.Because frequent rainfall causes the leaching loss of soil neutral and alkali composition such as ammonium, potassium, calcium, magnesium ion serious, is not easy acidic substance such as mobile iron, aluminium and builds up relatively, causes soil to be acidity or strong acid reaction.Simultaneously, compositions such as accumulative iron, aluminium be easy to soil constitution particularly the phosphorus element be combined into indissoluble and separate the aluminum phosphate of state, iron, therefore cause the phosphorus element that the validity of plant is reduced, promptly produce the negative impact of plant normal growth and the serious waste of capital goods in the agricultural sector, cause the pollution hazard of ecotope simultaneously, become the restraining factors of rural economy sustainable and healthy development.
Soil acid mainly influences the activity of various chemical reactions and soil microorganisms in the soil.Sour environment makes elements such as iron in the soil, aluminium, manganese have very high degree of activation, when pH less than 5 the time, the solubleness of aluminium, iron and manganese can be increased to the degree that is enough to poison the certain plants growth; Precipitation causes potassium, calcium, the loss of magnesium plasma to cause plant-growth to be injured; Because of suppressing biological activity of soil, acidity causes bad edatope influence.With regard to pH, be the optimum plant growth in the edatope condition of 6-7 neutral range, phosphorus plays an important role to growth and development of plant.Phosphorus is only second to the effect of nitrogen to the importance of growth and development of plants under the general condition, and phosphorus has and the equivalent effect of nitrogen to plant under certain condition; Scarce phosphorus not only influences plant normal growth and hinders the absorption of plant to other elements.Therefore, the nitrogen in the soil, potassium etc. just depend on the supply of phosphorus indirectly to the growth and development of plant effect.Under the neutrallty condition in the soil validity of phosphorus reach the highest, this moment, most of plants absorbed the resistance minimum of phosphorus from soil.Phosphorus depends primarily on the quantity of ionic state phosphorus to the validity of plant, and the quantity of ionic state phosphorus is decided by the pH value of the soil solution again.Soil pH is determined by wherein each kind of ion to a great extent to the influence of phosphorus validity.The phosphorus content that exists with ionic state in the edatope about PH6.5 is the highest.PH value when in other words, the validity of phosphorus is maximum in the soil is between the 6-7.Therefore, create suitable edatope,, improve agricultural performance, the very necessary behave of preserving the ecological environment improving utilization rate of fertilizer, promoting plant that effective absorption of nutrient is raising crop yield and quality, reduces the fertilising cost.
Various wastewater treatments produce a considerable amount of solid waste mud, and sludge treatment has become the important restraining factors of restriction various wastewater processing technologies and engineering development, and the stacking that does not add disposal is land occupation and cause secondary environmental pollution to endanger in a large number.
Notification number: CN1563274, open day: the Chinese patent literature of 2005.01.12 was announced " a kind of method of utilizing paper waste to handle the improving sludge acid soil ", this invention is meant that specifically the mud of the solid waste utilizing granularity 5 orders-100 purpose to handle the alkali paper-making pulping waste liquor to obtain-contain xylogen is material, with 1 ‰-10 ‰ of topsoil (soil that refers to the 0cm-20cm degree of depth) soil amount, take top application or improve acid soil (soil that refers to pH value≤6) with mode that the soil blending is executed, reduce soil acidity (target pH value 6-7), suppress harm ionic activity in the soil, improve the validity of plant nutrient in the soil, the environment of improving the soil, promote growth and development of plants, realize waste ' s reclamation.But this invents described method complex disposal process, only can improve acid soil, and still, our area of national acid soil is fewer, and the fertilizer efficiency meaning is not very big, and the Production Flow Chart complexity, also is difficult for promoting.
Notification number: CN1664064, open day: the Chinese patent literature of 2005.09.07 was announced " a kind of alkaline soil improver ", this invention proposes a kind of alkaline soil improver and newly fills a prescription, to improve the efficient of gypsum or phosphogypsum improvement alkaline soil, can be that main soil improvement agent is applied to not only alkali but also non-irrigated area also with gypsum or phosphogypsum.This alkaline soil improver, its composition comprise following weight part: gypsum 1, stalk 0.5-1.5, urea 0.01-0.08.A significant contribution of this invention is to utilize agricultural crops stalk mixed gypsum or mixed fertilizer industrial waste phosphogypsum chemical modifying and physically improved combining.Can not only fundamentally improve soil compaction, and the effect of soil improvement under the condition of not carrying out drip washing significantly is better than simple chemical modifying.But this invention cost is also higher, and the fertilizer efficiency meaning is also little, and the Production Flow Chart complexity, also is difficult for promoting.
