specific Embodiment approach 1

[0004] Embodiment 1: Add the retting solution after the reaction of the microbial degumming warm water retting method into the retting container in an amount of 50% of the volume of the retting container, and the original flax stems in the container have been soaked in warm water for 2 to 4 hours, Then fill up the retting container with clean water, and heat it to 30°C-37°C, add sodium chloride and urea into the retting container while heating, and add 74-92.6 grams of chlorine per cubic meter of retting container Sodium chloride and 129.6 to 231.5 grams of urea, after 72 to 88 hours, the retting ends.

[0005] The strains were activated with beef extract peptone solid medium for 24 hours at 30°C, and the activated strains were inserted into the retting container with 1% of the original flax stem weight in the retting container as the inoculum amount. The stems have been soaked in warm water for 2 to 4 hours, then fill the retting container with clean water, and heat it to 30°...

Abstract

Provided is a bacteria added retting liquid recycling method in warm water retting. The inventive retting method for flax comprises: inoculating the retting liquid produced by microorganism rapid degumming and warm water retting method for flax with the quantity 50 wt.% of the retting container to the retting container, in which the flax protocorm is soaked for 2-4 hours in warm water, then topping up the retting container with clean water, heating to 30-37 DEG C, meanwhile adding 74-92.6 g / m3 sodium chloride and 29.6-231.5 g / m3 urea, finishing the retting after 72-88 hours. The method can shorten the zymolysis cycle, improve the yield rate of the flax fiber, increase the intensity of the flax fiber, improve the flax fiber quality, reduce the sewage in the retting.

Description

Technical field: [0001] The invention relates to a method for retting with waste liquid of retting. Background technique: [0002] At present, the method of warm water retting adopted in our country is: firstly divide the raw flax stems into various grades, then manually bind the raw flax stems of the same grade into small bundles of about three kilograms each, and pack the bundled flax raw stems into In the retting tank, the loading density is 95-100 kg / m3, then fill the retting tank with clean water and soak for four hours (this is called 'first water' or 'one pass water'), after four hours the retting Drain the water in the pool, and then fill the retting pool with clean water (this is called "upper warm water" or "secondary water"). After filling, heat the retting pool to the required temperature with steam. This will consume a large amount of coal, and the existing retting waste liquid can only be discharged, which not only pollutes the environment, but also causes a w...
