Embodiment 1

[0019] Embodiment 1: the preparation of heavy metal adsorbent

[0020] A heavy metal adsorbent prepared from wine residues, prepared from the following weight (kg) component raw materials:

[0021] Wine pomace 25, rice husk 8, boric acid 1.5, lauric acid 0.15, hydroxyethyl cellulose 4, polyaspartic acid 0.15, disodium edetate 1.5, sodium chloride 4, sodium lignosulfonate 1.5, Additive 5, water 45;

[0022] Wherein, the auxiliary agent is made of the following raw materials in parts by weight:

[0023] Fresh tea leaves 25, fresh pine needles 4, fresh mulberry leaves 4, citric acid 3, oxalic acid 0.8, sodium citrate 1.5, sodium lauroyl sarcosinate 0.8, water 90;

[0024] The preparation method of auxiliary agent is:

[0025] Clean and crush fresh tea leaves, fresh pine needles and fresh mulberry leaves, mix them with sodium citrate, and grind them evenly, first add citric acid, oxalic acid and water and stir for 6 hours at 90°C and 400r / min, then add sodium lauroyl sarcosinat...

Embodiment 2

[0029] Embodiment 2: to the adsorption effect of heavy metal lead and copper

[0030] Take by weighing sorbent material 0.5g among the embodiment 1, join 1L heavy metal lead ion concentration in the water of 0.1g / L, in room temperature adsorption 1h, detect the concentration of remaining lead ion in the solution, record adsorption capacity and be 43.6mg / L g.

[0031] Take by weighing 0.5g of the adsorbent in Example 1, join 1L of heavy metal copper ion concentration in water of 0.1g / L, absorb at room temperature for 1h, detect the concentration of remaining copper ions in the solution, and record the adsorption capacity as 75.5mg / L g.

Abstract

The invention discloses a heavy metal adsorbent prepared from grape wine residues. The heavy metal adsorbent is prepared from the following raw materials in parts by weight: 20-30 parts of grape wine residues, 5-10 parts of rice husk, 1-2 parts of boric acid, 0.1-0.2 part of lauric acid, 3-5 parts of hydroxyethyl cellulose, 0.1-0.2 part of polyaspartic acid, 1-2 parts of ethylenediaminetetraacetic acid disodium salt, 3-5 parts of sodium chloride, 1-2 parts of sodium lignosulfonate, 4-6 parts of additives and 40-50 parts of water. The heavy metal adsorbent is prepared from waste grape wine residues as a main raw material, has the characteristics that heavy metals can be combined, the adsorption property is high and the adsorption capacity is large, is safe and environmentally friendly, free of toxicity or harm, free of secondary pollution to the environment in the wastewater treatment process, can save the energy and reduce emission, and is economical and practical.

Description

technical field [0001] The invention relates to the field of environmental treatment, in particular to a heavy metal adsorbent prepared from wine dregs and a preparation method thereof. Background technique [0002] With the development of the global economy and society, environmental pollution is becoming more and more serious. Industrial wastewater, as the main source of environmental pollution, has been a major problem that has plagued countries all over the world for a long time. Heavy metal ions in industrial wastewater have strong carcinogenic, teratogenic, and mutagenic effects, which pose a serious threat to human health and the ecological environment. Therefore, it is very important to strictly control the pollution of heavy metal wastewater. [0003] Traditional heavy metal wastewater treatment methods mainly include chemical precipitation, ion exchange, membrane separation, etc. These methods usually have problems such as large investment, high energy consumption,...
