Problems solved by technology

[0003] Most of the studies on the treatment of dye wastewater by fungi are carried out under sterilized conditions. Although a good treatment effect has been achieved under sterilized conditions, it cannot reflect the decolorization performance of fungi on dyes in actual conditions (non-sterilized conditions); sterilized conditions It is also impractical to treat dye wastewater under

Embodiment 1

[0025] The biosorption and regeneration method of mycelium balls in this embodiment includes preparation of mycelium balls, biosorption and regeneration of mycelial balls;

[0026] The preparation of the mycelium ball: including the configuration of the ball forming medium and the cultivation of the mycelium ball;

[0027] Preparation of ball-forming medium: adopt the following ingredients to make ball medium: potato juice prepared according to the ratio of 200g potatoes: 1L water, glucose 20g / L, NaCl1.0g / L, (NH 4 ) 2 SO 4 1.0g / L, KH 2 PO 4 0.5g / L and CaCl 2 0.05g / L; adjust the sphere-forming medium to acidic sphere-forming medium;

[0028] The preparation process of the potato juice is as follows: cut the potatoes into pieces, mix the potato pieces with water at a ratio of 200g / L, boil the water for 30 minutes, filter out the solids to obtain potato juice, add water to the potato juice, and make the diluted Potato juice is equal to the initial water volume.

Embodiment 2

[0048] The difference between this example and Example 1 is that in the method for biosorption and regeneration of mycelium balls in this example, the aeration time in the biosorption step lasts for 12 hours.

[0049] In this embodiment, the aeration time of 12 hours is adopted, which is suitable for the situation where the dye content in the wastewater is low.

Embodiment 3

[0051] The difference between this embodiment and the above embodiment is that in the method for biosorption and regeneration of mycelium balls in this embodiment, the aeration time in the biosorption step lasts for 18 hours.

Abstract

The invention discloses a mycelium pellet biosorption and regeneration method. The method includes the steps of preparation of mycelium pellets, specifically, spores are cultured into the mycelium pellets; biosorption, specifically, the mycelium pellets are used for conducting biosorption on anion azo dye waste water; and regeneration of the mycelium pellets, specifically, the mycelium pellets with dye adsorbed is desorbed in alkaline desorption liquid, the alkaline desorption liquid with the dye dissolved is recovered, and the desorbed regenerated mycelium pellets continue to be used for the step of biosorption. According to the mycelium pellet biosorption and regeneration method, biosorption and regeneration are conducted under the open non-sterilized condition by taking the advantages of extreme environment (such as high salinity and low pH) resistance, high adsorptive property, easy settlement and certain mechanical strength of the mycelium pellets, and a reactor is operated continuously with the biosorption technology as the core.

Description

technical field [0001] The invention relates to a method for biological adsorption and regeneration of mycelium balls. Background technique [0002] Azo dye wastewater is a kind of refractory industrial wastewater with a large amount of discharge in my country. Due to the complex quality of wastewater, conventional activated sludge methods are difficult to effectively treat this type of wastewater. Physicochemical treatment technologies such as coagulation sedimentation, advanced oxidation, etc. , has the disadvantages of large doses of chemicals, large amounts of toxic and harmful sludge, and high treatment costs. There are more and more studies on the use of fungi to treat dye wastewater, and the main mechanisms of fungal dye removal can be divided into three categories: biosorption, biodegradation, and bioaccumulation. Filamentous fungi can form mycelial balls with certain mechanical strength under certain culture conditions. The mycelial balls have good adsorption and se...
