Embodiment 1

[0013] (1) Plant treatment: select the vigorously growing Smilax, wash and remove the silt and phytoplankton attached to the plants. Select fresh emerald green and well-grown test materials, continue to wash them with tap water, and then transfer them to distilled water for acclimation and cultivation. The culture condition is an artificial climate chamber, with a light intensity of about 2800-3200lx, a humidity of 35%, a temperature of (20±1)°C, and a light-dark cycle ratio of 12h:12h. Acclimate and cultivate for 1 day.

[0014] (2) Phenol removal: waste water with low concentration of phenol: select plants that grow vigorously after domestication and cultivation, absorb the surface water with absorbent paper, weigh 80, and insert 20L of phenol treatment solution with a concentration of 6mg / L into the plastic Cultivate in the box, the temperature is controlled at 7-9°C, the light is 2800-3200lx, the light source is a fluorescent lamp, and the humidity is 35%. After 100 minut...

Embodiment 2

[0016] (1) Plant treatment: select the vigorously growing Smilax, wash and remove the silt and phytoplankton attached to the plants. Select fresh emerald green and well-grown test materials, continue to wash them with tap water, and then transfer them to distilled water for acclimation and cultivation. The culture condition is an artificial climate chamber, the light intensity is about 2800-3200lx, the humidity is 50%, the temperature is (20±1)℃, and the light-dark cycle ratio is 12h:12h. Acclimate culture for 1-2 days.

[0017] (2) Phenol removal: waste water with high concentration of phenol: select plants that grow vigorously after acclimation and cultivation, absorb the surface moisture with absorbent paper, weigh 320g, and insert it into plastic containing 20L of phenol treatment solution with a concentration of 500mg / L. Cultivated in a box, the temperature is controlled at 27-29°C, the light is 2800-3200 lx, the light source is a fluorescent lamp, and the humidity is 50...

Embodiment 3

[0019] (1) Plant treatment: select Vigorously growing Smilax, wash, remove the sediment and zooplankton attached to the plant; select fresh green and well-grown test materials, continue to wash with tap water, and then transfer to distilled water for further cleaning. Acclimatization culture; culture conditions are artificial climate chamber, light intensity 2800-3200lx, humidity 50%, temperature 21°C, light-dark cycle ratio 12h:12h, domestication culture for 2 days;

[0020] (2) Phenol removal: For water with a phenol content of 1mg / L, plant 80g of Smilax per 20L obtained from step (1), at a temperature of 7-9°C, with a light of 2800-3200lx, a fluorescent lamp as the light source, and a humidity of 50%. Cultivate for 100-140min.

Abstract

The invention relates to a method for removing phenol materials from water by using aquatic plants and belongs to the field of water ecological treatment. The method comprises the following steps: selecting potamogeton crispus growing vigorously, cleaning, and removing silt and zooplankton and phytoplankton from the plants; selecting fresh, emerald green and well-grown materials for the test, continuously washing with tap water, and conveying into distilled water to perform domesticated cultivation; and planting the domesticated plants into phenol-containing water and cultivating to purify the phenol materials. By the method, the phenol-containing wastewater is treated by the aquatic plants. The method has the advantages of readily available materials, wide distribution, low cost, simplicity in operation, no secondary pollution and the like.

Description

technical field [0001] The invention relates to a method for treating phenolic substances in water bodies by using aquatic plants, and belongs to the technical field of water ecological management. Background technique [0002] With the development of modern industry and the increase of population density, a large amount of untreated domestic sewage and industrial wastewater are directly discharged into water bodies, resulting in aggravated pollution of water bodies. Phenol-containing wastewater is a kind of industrial wastewater with great harm and wide pollution range, with wide sources and great harm. Wastewater mainly contains phenolic compounds, such as phenol, cresol, xylenol and nitrocresol. It mainly comes from industrial sectors such as coking plants, gas plants, and petrochemical plants, as well as the production processes of synthetic dyes, organic pesticides, and phenolic resins. For example, the mass concentration of phenol in wastewater produced during the co...
