Example Embodiment

[0030] Example 1

[0031] Preparation of heat treatment reaction solution:

[0032] Put ginkgo bark and ginkgo leaves into a pulverizer at a mass ratio of 5:1 to pulverize to obtain a mixture, put the mixture into an oven, and dry it for 2 hours at a temperature of 40 °C to obtain a dry material. Anhydrous ethanol was put into a beaker at a mass ratio of 1:10, the beaker was placed in a shaker, shaken and soaked for 3 hours, and after soaking, the filter residue and filtrate were obtained by suction filtration and separated for use;

[0033] The above filter residue was put into the reaction kettle, soaked with hydrochloric acid with a mass fraction of 3%, the reaction kettle was sealed, the temperature in the reaction kettle was raised to 60 ° C, and the stirring speed was 400 r / min under constant temperature conditions for 2 hours. Add 10% sodium hydroxide solution dropwise to the beaker to adjust the pH to 10 to obtain an alkaline mixed solution;

[0051] Preparation of heat treatment reaction solution:

[0052] Put ginkgo bark and ginkgo leaves into a pulverizer in a mass ratio of 5:1 to pulverize to obtain a mixture, put the mixture into an oven, and dry it for 3 hours at a temperature of 50 ° C to obtain a dry material. Anhydrous ethanol was put into a beaker at a mass ratio of 1:10, the beaker was placed in a shaker, and soaked for 4 hours in a shaker. After soaking, suction filtration was performed to separate the filter residue and filtrate, which were used for later use;

[0053] The above filter residue was put into the reaction kettle, soaked in hydrochloric acid with a mass fraction of 6%, the reaction kettle was sealed, the temperature in the reaction kettle was raised to 70 ° C, and the stirring speed was 500 r / min under constant temperature conditions for 3 hours. Add 15% sodium hydroxide solution dropwise to the beaker to adjust the pH to 12 to obtain an alkaline mixed solution;

Abstract

The invention discloses a preparation method of an algistat containing gingko endophyte, and belongs to the technical field of water treatment. Ginkgo biloba endophyte extracted from ginkgo bark and leaves is attached to algistat components; the ginkgo biloba endophyte has good sterilization and bacteriostasis capability; the pollution of the algistat to the environment can also be reduced by utilizing the gingko endophyte; meanwhile, plant fibers, lignin and other components are extracted from the ginkgo barks and leaves; carbonized fibers are generated in the subsequent carbonization process; meanwhile, carbonized micro-particles formed by carbonizing sugar molecules are embedded into the carbon nano-particles; the algae removal efficiency of the algistat is enhanced; the effect is quick; a silicon dioxide component is also introduced into the fiber component; silicon dioxidete components are adsorbed in the plant fibers, silicon dioxide nano-molecules are generated in a carbon fiberstructure again after the pH value is adjusted and high-temperature treatment is conducted, the surface roughness of carbon fibers is improved, meanwhile, the carbon fibers are coated and protected to a certain extent, the growth environment of the gingko endophytes is protected, and the algae removal time efficiency of the algistat is improved.

Description

technical field [0001] The invention discloses a preparation method of an algastatic agent containing endophytic bacteria of ginkgo, belonging to the technical field of water body treatment. Background technique [0002] With the development of economy and the increase of human activities, the eutrophication of lakes and reservoirs is becoming more and more serious. The algae bloom caused by eutrophication not only brings serious harm to the ecosystem, but also seriously threatens human health and survival, increases the cost of water treatment and maintenance, makes the water ecological environment unbalanced, and becomes a water resource environment. One of the major challenges facing the field. [0003] Algae bloom is a disaster phenomenon that frequently occurs in seawater and freshwater waters. It is called red tide in the ocean and algae bloom in freshwater. The algae that can form water blooms are mainly species in Cyanophyta and Chlorophyta. In eutrophic freshwate...
