Abstract

The invention discloses a method used for removing malachite green from waste water with sunflower seed shell biomass carbon adsorbent, and belongs to the technical field of waste water processing. The method comprises following steps: the sunflower seed shell biomass carbon adsorbent prepared via microwave heating, and sodium chloride are added into waste water containing 100 to 900mg / L malachite green and with a pH value of 2 to 8, adsorption is performed for 2 to 24 hours at a temperature of 20 to 60 DEG C, an obtained mixture is filtered for separation, and a filtrate is adjusted to be neutral, and then is discharged. The method used for removing malachite green from waste water is simple, cost is low, and no secondary pollution is caused.

Description

technical field

[0001] The invention belongs to the technical field of wastewater treatment, and relates to a method for removing malachite green in wastewater by using an adsorbent, in particular to a method for removing malachite green in wastewater by using a sunflower seed shell biomass carbon adsorbent. Background technique

[0002] Malachite green is a synthetic organic compound, which is not only a dye, but also a fungicide, and its chemical functional group trityl has carcinogenic effect. Malachite green is often used for dyeing wool, silk, leather, etc. In the aquaculture industry, malachite green is used to treat parasitic, fungal or bacterial infections of fish or fish eggs, but it has side effects such as high toxicity and high residue on certain seafood. Malachite green is deposited in fish and other foods, and reaches and accumulates in the human body or animals through the food chain, endangering human health and easily causing poisoning of human and animal l...
