Problems solved by technology

However, the cement wood body has a certain degree of alkalinity, and the pH is between 11 and 13. Improper control of the ratio can easily cause burning of seeds and seedlings; at the same time, the cement itself also has a negative impact on the fertility of the base material.

example 1-1

[0030] For the pulping red liquor collected from A paper mill, the pH is 4.8-5.0, and the MVC+MED-TC two-stage combined process is used for evaporation and concentration to a moisture content of 70%.

[0031] The chemical reaction ax was introduced, and the pH value of the concentrated solution was determined to be 3.5. Adjust the pH to 6.0 with slaked lime solution, and add dilute nitric acid with a percentage concentration of 33%, so that the pH of the material in the reactor was 3.0, and the temperature was controlled between 60 and 62°C. Between, stir for 35 minutes, cool.

[0032] Adding 2% zinc sulfate saturated solution, 3% magnesium sulfate saturated solution, 2% ferrous sulfate saturated solution, 3% manganese sulfate saturated solution by volume, reaction temperature control Between 50 and 52°C, stir for 20 minutes.

[0033] The paper-making red liquor lignin mixture processed through the above steps is further dried, and the drying process adopts the flash drying p...

[0035] For the pulping red liquor collected from B paper mill, the pH is 5.0-5.5, and the MVC+MED-TC two-stage combined process is used for evaporation and concentration to a moisture content of 40%.

[0036] Introduce a chemical reaction axe. After measurement, the pH of the concentrated solution is 1.5. Adjust the pH to 5.5 with quicklime, add dilute nitric acid with a percentage concentration of 35%, so that the pH of the material in the reactor is 1.5, and the temperature is controlled between 65 and 67°C. , stirred for 40 minutes, and cooled.

[0037] Add a 5% saturated solution of zinc sulfate by volume, a saturated solution of magnesium sulfate with a volume percentage of 2%, and a saturated solution of ferrous sulfate with a volume percentage of 3%. The reaction temperature is controlled between 55 and 57°C, and stirred for 25 minutes .

[0038] Fill the papermaking red liquor lignin mixture processed through the above steps directly. After testing, the total content ...

[0040] For the pulping red liquor collected from C paper mill, the pH is 5.0-5.5, and the MVC+MED-TC two-stage combined process is used for evaporation and concentration to a moisture content of 50%.

[0041] Introduce a chemical reaction axe. After measurement, the pH of the concentrated solution is 1.5. Adjust the pH to 5.5 with quicklime, add dilute nitric acid with a percentage concentration of 35%, so that the pH of the material in the reactor is 3.5, and the temperature is controlled between 68 and 70°C. , stirred for 30 minutes, and cooled.

[0042] Add 2% zinc sulfate saturated solution, 3% magnesium sulfate saturated solution, 3% ferrous sulfate saturated solution, 2% manganese sulfate saturated solution by volume, reaction temperature control Between 58-60°C, stir for 20 minutes.

[0043] The papermaking red liquor lignin mixture processed in the above steps is further dried, and the drying process adopts a spray drying process. After the drying is completed, the s...

Abstract

The invention provides a preparation and use method which is applicable to nutritive base material additives for revegetation of the side slopes on the roads and bare mountains, namely an additive which adopts functional materials as nutritive base materials and is obtained by the processing of carrying out evaporation concentration, nitric acid oxidation, chelation (or neutralization and chelation) by adding sulphate (or oxide), drying and packaging or direct filling and the like to red liquor of pulp and paper making by acid process. The additive is reasonably matched with a cement binder, can adjust acidity and alkalinity of the base materials, prevent burning of seeds and seedlings caused by incorrect control of cement using amount, simultaneously has functions of supplying fertilizer, preserving fertilizer and water and modifying soil, can effectively solve the problem that the vegetation is degraded in the existing technology of revegetation and ecological protection of bare slope and the base materials are easy to be washed, is greatly convenient to construction, has wide application prospect, simultaneously opens up a new path in aspect of treatment and comprehensive utilization of paper-making waste liquor and provides a new energy-saving emission-reducing technology for numerous paper-making factories.

Description

technical field [0001] The present invention relates to a nutrient substrate additive for road slope and bare mountain vegetation restoration, more specifically, relates to a kind of lignin functional material obtained by processing papermaking pulping red liquor as roadside Preparation and application method of nutrient substrate additive for slope and bare mountain vegetation restoration. Background technique [0002] With the rapid development of my country's economy, large-scale urban and rural construction and transportation construction have left a large number of road and railway slopes and abandoned quarries in various places, and the area of ​​exposed slopes is increasing by hundreds of millions of square meters every year. A large number of road slopes and exposed quarries have seriously damaged urban and rural ecological landscapes and caused soil erosion. [0003] For the treatment of road slopes and exposed mountains, people used a large number of simple engine...
