Problems solved by technology

Pleurotus eryngii hyphae grow on it, which can be absorbed and utilized by the mycelium as nutrients, and can also be used as a carrier to fix the mycelium of Pleurotus eryngii. These wastes can be used as cultivation materials for other edible fungus cultivation, and can be used as feed raw materials, but there is still a large amount of cultivation waste that cannot be recycled
Using Pleurotus eryngii cultivation waste to treat dye wastewater aims to improve the high cost of dye wastewater treatment and provide a new way for dye wastewater treatment
At present, there are almost no reports about utilizing cultivation waste to treat dye wastewater, so the present invention lays the foundation for rational utilization of dye wastewater treatment and cultivation waste

Embodiment 1

[0012] Example 1: Study the effect of different metal ions on enzyme activity.

[0013] Pleurotus eryngii cultivated material was provided by the Laboratory of Microbiology Engineering, College of Life Sciences, Fujian Agriculture and Forestry University. The results of measuring enzyme activity of cultivated material after harvest of Pleurotus eryngii showed that Pleurotus eryngii secreted laccase, manganese peroxidase, cellulase and hemicellulase, but not lignin peroxidase.

[0014] When Mn 2+ When the concentration is 2.5 mmol / L, laccase is activated; Ag + When the concentration is 5 mmol / L, both laccase and manganese peroxidase are inhibited; Fe 2+ At a concentration of 2.5 mmol / L, it inhibits laccase and promotes the secretion of manganese peroxidase, Ag + , Fe 2+ It has a strong inhibitory effect on laccase. Add 2.5 mmol / L Mn respectively 2+ , 5 mmol / L Ag + , 2.5 mmol / L Fe 2+ After the decolorization of aniline blue, the result showed that adding 2.5 mmol / L Mn 2+ The syste...

Embodiment 2

[0015] Example 2: Optimization of decolorization conditions for aniline blue in cultivation material of Pleurotus eryngii after harvest

[0016] After the harvested Pleurotus eryngii cultivated material is pulverized with a pulverizer and mixed, 6 g are respectively weighed and put into a 100 mL reaction system, shaken in a constant temperature shaker, and regularly sampled to verify the temperature, pH, speed, and dye Concentration, mediator molecule, Mn 2+ The effect of concentration on the decolorization of aniline blue. Observe the decolorization to measure its absorbance and calculate the decolorization rate.

[0017] The results are as follows:

[0018] 1. Temperature: the result when the reaction system is decolorized for 210 minutes. When the temperature is from 10-30℃, the decolorization rate of aniline blue will increase with the increase of temperature. When the temperature is higher than 30℃, the decolorization rate will decrease with the increase of temperature. If the ...

Embodiment 3

[0027] Example 3: Treatment of printing and dyeing wastewater and toxicological experiment with cultivation material after harvest of Pleurotus eryngii

[0028] The UV scanning spectra before and after dye degradation showed that the characteristic absorption peak of aniline blue at 585 nm disappeared, indicating that the cultivated material after harvest of Pleurotus eryngii can degrade aniline blue. Under the best decolorization conditions, the removal rate of aniline blue COD was 53.6%. The results of degradation of industrial printing and dyeing wastewater by cultivated material after harvest of Pleurotus eryngii showed that the amount of cultivated material added was positively correlated with the COD removal rate of printing and dyeing wastewater. At 30℃, 400 μmol / L ABTS, 5 mmol / L Mn 2+ , Under the condition of 110 rpm, the COD removal rate reached 86.1%. The results of toxicological experiments showed that the germination rates of rice seeds in solution culture before and...

Abstract

The invention concretely relates to a method for processing aniline-blue-containing pollution wastewater by using a cultivation material of harvested pleurotus eryngii. The method comprises: crushing the cultivation material of harvested pleurotus eryngii by using a crusher, pouring into aniline-blue-containing pollution wastewater, oscillating in a shaking table at a constant temperature, wherein the decoloring conditions for 100 mg / L of the aniline-blue-containing pollution wastewater comprises that the temperature is 20-40 DEG C, the molecular mediator is ABTS with the concentration of 400 mu mol / L, the Mn<2+> concentration is 1-3 mol / L, and the rotation speed is 50-150 rpm. By utilizing pleurotus eryngii cultivation waste material to process dye wastewater, environment is purified and also waste reutilization is realized, so that the method has good development prospect. The cultivation material of harvested pleurotus eryngii is taken as an experiment material for processing dye wastewater, is capable of adsorbing a part of a dye, and also is capable of secreting lignin digestive enzyme for degrading a toxic organic dye with a complex structure, and has important practical meaning on current dye wastewater processing.

Description

Technical field [0001] The invention specifically relates to a method for treating aniline blue-contaminated wastewater with cultivated material after harvest of Pleurotus eryngii. Background technique [0002] With the continuous development of economy, the living environment on which mankind depends for survival has been severely damaged. The pollution of printing and dyeing wastewater in the textile industry is becoming more and more serious. How to treat dye chemical wastewater economically and effectively is an urgent problem in environmental protection. Dye chemical wastewater has the basic characteristics of high chroma, high COD, high salinity, high toxicity, and low B / C. The synthetic organic dyes have the characteristics of stable chemical structure. These refractory pollutants will Cause a series of environmental and ecological problems. [0003] Traditional physical and chemical treatment technologies have limitations such as high cost and high secondary pollution, wh...
