[0004] Mikania micrantha H.B.K, also known as Eupatorium micrantha and Eupatorium micrantha, belongs to Asteraceae (Asteraceae) and is a perennial herbaceous or woody vine. It is native to Central America and is now a tropical and subtropical Although a lot of research has been done on the medicinal and pesticide activities of Mikania micrantha at home and abroad, there is no report on the use of Mikania micrantha in the treatment of dye wastewater. At present, the use of Mikania micrantha in the treatment of printing and dyeing wastewater is still in a blank stage.

Embodiment 1

[0027] Mikania micrantha comes from the wild in Mangshi, Dehong Prefecture. The stem of Mikania micrantha with a length of 40cm is cut, placed in a container with tap water, and then placed indoors in a sunny place for 15 days to grow fibrous roots; Mikania micrantha, which has basically the same growth and weight, is inserted into the treatment pool containing the printing and dyeing wastewater to be treated;

[0028] The amount of printing and dyeing wastewater to be treated is 250mL, the concentration of basic fuchsin is 10mg / L, and the pH is adjusted to between 2 and 12. There is a plant of Mikania micrantha in each treatment pool. After 3 days of cultivation, samples are taken to determine the alkaline substances in the printing and dyeing wastewater. Red concentration, calculate the removal rate, the result is as follows figure 1 shown;

[0029] Among them, Mikania micrantha was cultured in a basic fuchsin solution with a pH of 2 and 12, and died after growing for 1 day...

Embodiment 2

[0031] Cut off the stem of Mikania micrantha with a length of 40 cm, place it in a container with tap water, and then place it indoors in a sunny place to cultivate for 15 days, until it grows fibrous roots; select Mikania micrantha with a fibrous root of 10 cm, basically the same growth, and basically the same weight. Insert it into the treatment tank containing the printing and dyeing wastewater to be treated;

[0032] The printing and dyeing wastewater to be treated is 250mL, the concentration of basic fuchsin is adjusted to 5, 10, 15, 20, 30, 40, 50 mg / L, and the pH is 7. There is a plant of Mikania micrantha in each treatment pool, and in different time periods Sampling is carried out to measure the concentration of basic fuchsin in the printing and dyeing wastewater, and the removal rate is calculated. The results are as follows: figure 2 shown;

[0033] From figure 2 It can be seen from the figure that Mikania micrantha was cultured in a basic fuchsin solution with ...

Embodiment 3

[0035] Cut off the stem of Mikania micrantha with a length of 40 cm, place it in a container with tap water, and then cultivate it in a sunny place indoors for 15 days until it grows fibrous roots; choose Mikania micrantha whose fibrous roots are 10 cm, grow well, and have basically the same weight. It is inserted into the treatment tank containing the printing and dyeing wastewater to be treated;

[0036] The printing and dyeing wastewater to be treated is 250mL, the concentration of basic fuchsin is 20mg / L, and the pH is 7. There is a plant of Mikania micrantha in each treatment pool, which is adsorbed for 3 days to obtain the adsorbed Mikania micrantha and the treated printing and dyeing wastewater;

[0037] Recycling: recycle the adsorbed Mikania micrantha, specifically cut off and discard the part of the absorbed Mikania micrantha with fibrous roots, take the remaining part, put it in water, and then cultivate it in a sunny place indoors for 15 days. It grows fibrous root...

Abstract

The invention discloses an adsorption method for basic fuchsin in printing and dyeing wastewater. The adsorption method comprises the following steps: (1) culture of mikania micrantha: cutting out a section of the mikania micrantha, putting the mikania micrantha into water, culturing in an indoor sunny position for 10 to 20 days, and waiting until the mikania micrantha break out into fibrous roots; (2) adsorption of the basic fuchsin: selecting the mikania micrantha of which the fibrous roots are 8 to 12 cm in length and uniform in weight, inserting the mikania micrantha in a treating pond filled with to-be-treated printing and dyeing wastewater, inserting at least four strains of the mikania micrantha in the printing and dyeing wastewater for each liter, and enabling the adsorption time to be 1 to 7 days, thus obtaining adsorbed mikania micrantha and treated printing and dyeing wastewater. The adsorption method disclosed by the invention utilizes the mikania micrantha to remove the basic fuchsin in the wastewater, and has the advantages of high treatment efficiency, good treatment effect, high aesthetic value and low treatment cost, secondary pollution cannot be generated, and the purpose of water purification is achieved; meanwhile, related support and basis are provided for biomass resource reutilization of the mikania micrantha and establishment of water plant repairing feasibility in the field of printing and dyeing wastewater treatment.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to an adsorption method for basic fuchsin in printing and dyeing wastewater. Background technique [0002] The printing and dyeing industry is one of the heavily polluting industries, and it is the focus of attention in the field of wastewater treatment. Moreover, the printing and dyeing wastewater is dark in color, complex in composition, rich in toxic substances, and difficult to degrade, thus causing serious environmental pollution. Basic fuchsin widely exists in printing and dyeing wastewater. This type of wastewater containing basic fuchsin has a very bright color so that even when the concentration is very low, the chroma of the water body is very high, which seriously interferes with light transmission and chroma. Deeper wastewater will not only cause aesthetic unpleasantness, but also affect the amount of incident light in the water body, reduce the ...
