Problems solved by technology

When the precipitation method is used to remove arsenic in water, more chemical reagents will be consumed, and attention should be paid to the stability of the arsenic-containing sludge produced.
Otherwise, if it is not handled properly, the arsenic pollutants in the sedimented sludge will be released during the storage process, causing secondary pollution and natural pollution.

Embodiment 1

[0018] experiment procedure

[0019] Carefully dig out the spider plants, aloe vera and pothos from the cultivation soil, wash the roots and set aside.

[0020] Prepare six bottles of 100ppb (100mg / l) arsenic solution respectively. Put the washed various plants into the solution, observe their growth status and regularly measure the content of arsenic in the water. The volumes and growth conditions of each solution are shown in Table 1.

[0021] Table 1 Observation record of various landscape plants adsorbing arsenic in water

[0022]

[0023] Summarize

[0024] It can be seen from the above table that aloe vera and pothos grow well, while Chlorophytum is relatively drought-tolerant and not very cold-tolerant plants. Therefore, after 6 days of adsorption in water at 9°C, the growth of roots and leaves has been poor. And its arsenic content also increased accordingly. Considering comprehensively, the arsenic content of Podophyllum 2# reached the standard, and the growth...

Abstract

The invention discloses the application of scindapsus aureus to the drinking water dearsenization. Compared with the chemical precipitation method and the physical adsorption method in the prior art, the invention uses all natural green plants, dose not need the genetically-modified cultivation treatment, ensures that the arsenic adsorbed to the roots of the plants can not be easily released, is safer and easier, has high operability and has the function of beautifying the environment.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to the application of a plant in the arsenic removal treatment of drinking water. Background technique [0002] Arsenic is a well known toxic element. In view of the great harm of arsenic to human health and the increasingly serious arsenic pollution, in 1993, WHO took the lead in raising the index value of arsenic in drinking water from 50 μg / L to 10 μg / L. Subsequently, the European Union, Japan, and the United States also set their drinking water arsenic standards at 10 μg / L. my country's new national standard "Drinking Water Sanitation Standard" (GB5749-2006) implemented since July 1, 2007, raised the standard limit of arsenic in drinking water from no more than 50 μg / L in the original national standard to no more than 10 μg / L . [0003] At present, there are many researches on arsenic removal treatment of drinking water at home and abroad, and the main methods of water treatment...
