Problems solved by technology

[0003] In the existing natural rubber latex processing, concentrated latex or latex standard rubber is usually prepared by concentrating and separating natural latex or direct coagulation. The latex serum separated in the processing is hardly used at present and is discharged from the production system as environmental pollutants and waste water. , the enterprise still needs to treat its wastewater to reach the standard before it can be discharged
The remaining rubber clear slurry from natural rubber latex processing is the main source of pollution in natural rubber processing plants, accounting for more than 70% of the pollution load. The waste water treatment costs are high, and the waste water discharge seriously pollutes the environment. It is one of the main problems that enterprises need to solve urgently.

Embodiment 1

[0018] The specific process is as follows:

[0019] (1) Adopt disc type high-speed centrifuge to separate natural latex into two parts of concentrated latex and skim serum in advance under 10000 rev / min conditions, and the skim serum of separation is collected in container separately; (the concentrated that centrifugation obtains Latex will be reprocessed into products such as concentrated latex or latex label);

[0020] (2) The skim serum slurry obtained from step (1) is concentrated by RO membrane to remove 40-60% of the contained water and then becomes the skim serum concentrate;

[0021] (3) Add 4-5% (wt / wt) urea, 1-2% (wt / wt) sodium silicate and appropriate amount of zinc oxide to the skim concentrate obtained in step (2), and mix the skim concentrate The pH value of the mixture is adjusted to 9-9.5, tested, subpackaged and sealed away from light to obtain a water and soil conservation preparation product.

[0022] The above-mentioned water and soil conservation prepara...

[0030] The specific process is as follows:

[0031] (1) Adopt disc type high-speed centrifuge to separate natural latex into two parts of concentrated latex and skim serum in advance under 10000 rev / min conditions, and the skim serum of separation is collected in container separately; (the concentrated that centrifugation obtains Latex will be reprocessed into products such as concentrated latex or latex label);

[0032] (2) The skim serum slurry obtained from step (1) is concentrated by RO membrane to remove 40-60% of the contained water and then becomes the skim serum concentrate;

[0033] (3) Add selected microbial strains and 5-10% (wt / wt) waste molasses to the rubber serum concentrate obtained in step (2), and seal and ferment at 25°C-35°C for 10-12 hours At this time, the pH value of the slurry is naturally adjusted to 6-6.5, and then filtered with muslin cloth to remove impurities, then tested, subpackaged and sealed in a dark place to obtain a compound microbial liqui...

Abstract

The invention discloses a method for producing an agricultural biological agent with natural latex separating liquid. The method comprises the steps that natural latex is separated into two parts in advance, namely concentrated latex and latex skim slurry, through a high speed centrifuge, and then the two parts are processed separately; after part of moisture in the latex skim slurry is removed through an RO membrane, a concentrated latex skim solution is obtained; a proper amount of urea and sodium metasilicate are added to the concentrated latex skim solution to adjust pH value, and then a water and soil conservation agent is obtained; selected microorganism strains and a proper amount of waste molasses are added to the concentrated latex skim solution, sealed fermentation is conducted, and then liquid microbial agent is obtained; selected microorganism strains, a proper amount of waste molasses and inorganic fertilizer are added to the concentrated latex skim solution, and then liquid agricultural microbial fertilizer is obtained. According to the method, the latex skim slurry obtained by processing and separating the natural latex is prepared into the agricultural biological agent which is used for agricultural production and soil and water environment restoration, the environmental pollution problem can be solved, furthermore, the yield of agricultural products can be raised, quality of the agricultural products can be improved, ecological environment quality can be improved, and obvious social benefits, economic benefits and ecological environment benefits are achieved.

Description

technical field [0001] The invention relates to a production method of an agricultural biological agent, in particular to a method for preparing an agricultural biological agent by using natural rubber latex separation liquid secreted by Hevea brasiliensis as a raw material. Background technique [0002] Hevea brasiliensis is a very important and effective green "bioreactor" and "processing plant". The natural latex produced by the rubber tree's unique latex production and latex discharge system is an environmentally friendly and renewable natural biological Material. [0003] In the existing natural rubber latex processing, concentrated latex or latex standard rubber is usually prepared by concentrating and separating natural latex or direct coagulation. The latex serum separated in the processing is hardly used at present and is discharged from the production system as environmental pollutants and waste water. , Enterprises also need to treat their wastewater to meet the ...
