Description
Technical field
The present invention relates to soil and fertilizer preparing technical field, be specially the method utilizing papermaking-method reconstituted tobaccos waste liquid to produce saline and alkaline (acidifying) soil conditioner.
Background technology
Papermaking-method reconstituted tobaccos is a state-of-the-art technology of tobacco waste comprehensive utilization in the world at present, but the making beating in paper industry has been continued to use due to this technology, the Technologies such as process of manufacturing paper with pulp and natural extract separation, cause and production process creates substantial amounts of waste water, all bring serious puzzlement to environment and manufacturing enterprise. Generally often producing 1 ton of product and need to discharge the waste water of more than 70 tons, this produces waste water except containing materials such as Nicotiana tabacum L. organic matter and Nicotiana tabacum L. chopped fiber, possibly together with the macronutrient of the applicable crop growths such as substantial amounts of calcium carbonate, ammonia nitrogen and organophosphor. And the PH of each process section waste discharge is respectively less than 7, presents faintly acid, it is suitable for producing alkaline land soil regulator.
Salt-soda soil is dyskinetic low productive soil, and its principal contradiction is containing too much soluble organic fraction, soil liquid excessive concentration, crop water suction difficulty. In this kind of soil, soil nutrient balance is destroyed, and affects the normal absorption of nutrient. The main cause causing salt-soda soil enlarged areas is that hydropenia is short of rain, irrigation water salinity high, evaporation capacity is excessive, the salinity of depth of soils is absorbed by hair and accumulates to earth's surface. My China has more than 400,000,000 mu salt-soda soils at present, and the degree of salinization of soil expands, and one of the vital task that the agricultural production amount in salt-soda soil is China's agricultural development is also improved in transformation salt-soda soil.
For this, study a kind of utilize papermaking-method reconstituted tobaccos waste water produce alkaline land soil regulator method, tool is of great significance.
Summary of the invention
It is an object of the invention to the problems such as big for papermaking-method reconstituted tobaccos enterprise wastewater discharge capacity, treatment cost is high, environmental pollution is serious, and containing being suitable for the characteristic such as macronutrient of crop growth, it is provided that a kind of method utilizing papermaking-method reconstituted tobaccos waste liquid to produce Reyulation agent for saline-alkali soil.
The purpose of the present invention is achieved through the following technical solutions.
Utilizing the method that papermaking-method reconstituted tobaccos waste liquid produces Reyulation agent for saline-alkali soil, method step is as follows:
A) taking papermaking-method reconstituted tobaccos waste liquid to be filtered separating, filtering mesh number is 3-10 order; Described waste liquid is the extraction section of papermaking-method reconstituted tobaccos production, evaporation and concentration section, the mixed liquor of coating section, the waste liquid that profiled section any one section of manufacturing paper with pulp produces or two of which waste liquid;
B) after isolated by filtration, liquid phase part being sent into concentrator and carries out cryogenic vacuum concentration, the solid content of concentrate is 30%-50%;
C), after concentration, in mass ratio 60%-80% concentrate, 10%-35% organic carrier and 1-5% microbial bacterial agent are carried out mix, and stir; Described organic carrier can be a kind of or wherein several mixture in agricultural crop straw, mushroom bran, calcium carbonate, sandy soil, weathered coal, and microbial bacterial agent is commercially available complex microorganism bacterium solution;
D) low-temperature material after mix is dried to moisture 20 �� 2%, be then fed into granulator;
E) by particle diameter after granulating at the particle drying of 1-4mm to moisture lower than 15%.
In the inventive method, after concentration, the usage ratio of papermaking-method reconstituted tobaccos waste liquid is up to 60%-80%, it is possible to a large amount of use papermaking-method reconstituted tobaccos waste liquids; The Reyulation agent for saline-alkali soil prepared can significantly reduce salt alkali concn around seed root system, reduces the saline and alkaline toxic action to crop, thus promoting the growth of crops. The present invention can realize turning waste into wealth, and saves cost, it is achieved papermaking-method reconstituted tobaccos enterprise sewage zero-discharge. The present invention, by papermaking-method reconstituted tobaccos waste liquid adds organic carrier and microbial bacterial agent, has produced saline and alkaline (acidifying) soil conditioner of high value, has had small investment, instant effect, the features such as cost is low.
