High-adsorbability composite material for sewage treatment as well as preparation method thereof

Abstract

The invention discloses a high-adsorbability composite material for sewage treatment. The high-adsorbability composite material comprises the following raw materials in parts by weight: 18 to 30 partsof polyacrylamide hydrogel, 6 to 12 parts of hirudin, 5 to 17 parts of glucomannan glue, 6 to 17 parts of sodium aluminosilicate, 4 to 10 parts of Curdlan powder, 2 to 5 parts of calcium phosphate, 1to 3 parts of L-lysine, 2 to 7 parts of lotus root powder, 1 to 5 parts of sophocarpidine, 3 to 6 parts of polymethylacrylic acid, 3 to 5 parts of modified waste water purifier activated carbon filter element powder and 60 to 90 parts of deionized water. The high-adsorbability composite material for sewage treatment has the advantages of high adsorption capacity, high selectivity and high efficiency, can capture various metal ions in a water body, has high removal rate on various metal ions in the heavy metal water and has treatment efficiency; furthermore, the treatment method is simple, andthe high-adsorbability composite material only needs to be thrown into the water during use.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-adsorption composite material for sewage treatment and a preparation method thereof. Background technique [0002] Traditional heavy metal treatment methods mainly include chemical treatment, ultrafiltration and adsorption. Although the chemical method has a fast purification speed and a simple process, it is prone to secondary pollution and difficult to recycle the wastewater; the ultrafiltration method is complicated in process, high in cost and poor in effect; the adsorption method is currently the most commonly used method in the treatment of heavy metal wastewater with low cost. , simple operation, no secondary pollution and other advantages. Currently commonly used adsorbents such as activated carbon, zeolite, ion resin, chelating resin, etc., have been well applied. However, the above-mentioned adsorbents have disadvantages such as low adsorption capacity...
