Abstract
The invention provides a method for producing a saline alkali soil conditioner by use of a paper-making reconstituted tobacco waste liquid. The method comprises the following steps: filtering and separating the paper-making reconstituted tobacco waste liquid, performing low-temperature vacuum concentration on the filtered and separated liquid phase part to obtain a concentrate in which the solid content is 30%-50%, next, mixing, selecting an organic matter carrier as one or a mixture of several of crop straws, mushroom bran, calcium carbonate, sandy soil and weathered coal, and a microbial agent as a commercial complex microorganism solution, drying the mixed materials until the moisture content is 20+/-2% and then pelletizing; then drying the pelletized particles with the particle size ranging from 1 to 4mm until the moisture content is lower than 15%. The method is capable of utilizing the paper-making reconstituted tobacco waste liquid to a large extent, the obtained saline alkali soil conditioner is capable of remarkably reducing the saline alkali concentration in the surrounding of the root system of seeds, reducing the toxic and harmful effects, produced by salt and alkali, on crops, and thus promoting the growth of the crops.
Description
Technical field
The present invention relates to soil and fertilizer preparing technical field, be specially the method for utilizing papermaking-method reconstituted tobaccos waste liquid to produce saline and alkaline (acidifying) soil redeposition.
Background technology
Papermaking-method reconstituted tobaccos is the state-of-the-art technology that tobacco waste fully utilizes in the world at present, but because this technology has been continued to use the making beating in paper industry, the Technologies such as the process of manufacturing paper with pulp and natural extract separation, cause in production process and produced a large amount of waste water, all brought serious puzzlement to environment and manufacturing enterprise.1 ton of product of common every production need discharge 70 tons of above waste water, and this factory effluent, except containing the materials such as tobacco organic matter and tobacco staple fibre, also contains the macronutrient of the applicable crop growths such as a large amount of calcium carbonate, ammonia nitrogen and organophosphorus.And the PH of each process section waste discharge is all less than 7, present slightly acidic, be suitable for producing alkaline land soil conditioning agent.
Saltings is obstacle low productive soil, and its principal contradiction is to contain too much solubility salinity, soil solution excessive concentration, crop water suction difficulty.In this class soil, soil nutrient balance is destroyed, and affects the normal absorption of nutrient.The major cause that causes saltings enlarged areas is that lack of water is short of rain, irrigation water salinity is high, steam output is excessive, the salinity of depth of soils is absorbed to earth's surface and accumulated by hair.My China has more than 400,000,000 mu saltings at present, and the degree of salinization expands, and transformation salinity ground the agriculture production amount that improves saltings are one of vital tasks of China's agricultural development.
For this reason, study a kind of method of utilizing papermaking-method reconstituted tobaccos waste water to produce alkaline land soil conditioning agent, tool is of great significance.
Summary of the invention
The object of the invention is the problems such as large for papermaking-method reconstituted tobaccos enterprise wastewater quantity discharged, treatment cost is high, environmental pollution is serious, and contain the characteristic such as macronutrient that is applicable to crop growth, a kind of method of utilizing papermaking-method reconstituted tobaccos waste liquid to produce Reyulation agent for saline-alkali soil is provided.
Object of the present invention is achieved through the following technical solutions.
Utilize papermaking-method reconstituted tobaccos waste liquid to produce the method for Reyulation agent for saline-alkali soil, method steps is as follows:
A) get papermaking-method reconstituted tobaccos waste liquid and carry out filtering separation, filtering mesh number is 3-10 order; Described waste liquid is extraction section, the evaporation concentration section that papermaking-method reconstituted tobaccos is produced, the waste liquid of coating section, any one section of generation of the profiled section of manufacturing paper with pulp or the wherein mixed solution of two kinds of waste liquids;
B) after filtering separation, liquid phase part is sent into thickening equipment, and to carry out cryogenic vacuum concentrated, and the solid content of enriched material is 30%-50%;
C) after concentrated, in mass ratio 60%-80% enriched material, 10%-35% organic carrier and 1-5% microbiobacterial agent carried out to mix, and stir; Described organic carrier can be a kind of in agricultural crop straw, bacterium chaff, calcium carbonate, sandy soil, weathered coal or several mixture wherein, and microbiobacterial agent is commercially available composite microbial bacteria liquid;
D) low-temperature material after mix is dried to moisture content 20 ± 2%, then send into tablets press and granulate;
E) by particle diameter after granulating at the particle drying of 1-4mm to moisture content lower than 15%.
In the inventive method, the usage ratio of concentrated rear papermaking-method reconstituted tobaccos waste liquid, up to 60%-80%, can be used papermaking-method reconstituted tobaccos waste liquid in a large number; The Reyulation agent for saline-alkali soil making can significantly reduce seed root system salt alkali concn around, reduces the saline and alkaline toxic action to crop, thereby promotes the growth of farm crop.The present invention can realize turns waste into wealth, cost-saving, realizes papermaking-method reconstituted tobaccos enterprise sewage zero-discharge.The present invention, by papermaking-method reconstituted tobaccos waste liquid is added to organic carrier and microbiobacterial agent, has produced saline and alkaline (acidifying) soil redeposition of high value, has less investment, instant effect, the feature such as cost is low.
